SMRs most expensive of all electricity technologies per kW generation

31 Mar, 2025 By Tom Pashby
Small modular reactors (SMRs) are projected to be the most expensive source per kW of electricity generated when compared with natural gas, traditional nuclear and renewables.

Mini nuclear reactor rush has a short half-life.

By Rob Cyran,
The rush to produce mini nuclear reactors on the cheap might have a short
half-life. In search of vast quantities of power for the data centers
fueling artificial intelligence, Meta Platforms, Alphabet and Amazon have
backed a goal, to triple the world’s nuclear power capacity by 2050.
The prospects for nuclear are indeed brightening, but it is still more
expensive and far slower to build than renewables. The upstart approach of
making smaller, identikit reactors will struggle even harder to close that
gap. Theoretically, SMRs can reduce costs by simplifying the underlying
design into a set of mass-produced, standard parts made off-site. About 95
companies are actively chasing this dream, according to John Ketchum, chief
executive of NextEra, the nation’s largest power developer.
Big names are in the fray, like OpenAI chief Sam Altman and his side project Oklo, or
Google and Amazon, which have invested in Kairos and X-energy,
respectively. UK-based engineering giant Rolls-Royce is urging the British
government to begin moving ahead with new projects.
This idea isn’t entirely new. The U.S. built some small commercial reactors in the 1960s.
But bigger reactors benefit from economies of scale, requiring
proportionately less material and fewer operating staff, resulting in a
one-third advantage versus smaller plants in costs per kilowatt of power,

Bavarian SMRs & Hydrogen Vans: What Could Possibly Go Wrong?

Michael Barnard https://cleantechnica.com/2025/04/01/bavarian-smrs-hydrogen-vans-what-could-possibly-go-wrong/
First Hydrogen Corp, a Canadian firm with more ambition than balance sheet, has now turned its sights on Germany — arguably the worst possible place to mix hydrogen hype with small modular nuclear reactors. The company, known mostly for a hydrogen van prototype and a team structure with more CEOs than engineers, is proposing a new strategy: use SMRs to produce hydrogen in Europe. Specifically, Germany.
The same Germany that just shut down its last nuclear plant, has strong anti-nuclear public
sentiment, and boasts some of the world’s most rigorous licensing hurdles for anything
remotely radioactive. As ideas go, this one isn’t just premature — it’s completely divorced from geopolitical, technological, and economic reality.
First Hydrogen’s European push is being channeled through its subsidiary, First Hydrogen
GmbH, an entity that appears to have been created to give the illusion of boots on the ground.
Back home, they’ve created First Nuclear Corp to drive this atomic angle, despite having no
nuclear licenses, no reactor designs, no partnerships with reactor vendors, and no market for
their product. The goal, supposedly, is to deploy SMRs to generate electricity that will then be
used to produce green hydrogen. This hydrogen would then presumably be used to fuel their
not-yet-commercial light commercial vehicles. Vehicles which, in independent UK trials,
consumed about 3.3 kilograms of hydrogen per 100 kilometers, making them far less efficient
than any battery-electric alternative, and certainly more expensive.
Let’s set aside for a moment the inconvenient truth that SMRs don’t exist yet in commercial
form. There are prototypes on paper, pilots under development, and timelines that stretch
comfortably into the late 2030s, assuming nothing goes wrong. But what’s really being
proposed here is to power a struggling hydrogen vehicle strategy with a non-existent nuclear
technology in a jurisdiction where nuclear projects are politically toxic and legally tangled. This is not a roadmap. It’s a Mad Libs of energy buzzwords.
Germany has made its stance on nuclear abundantly clear. After Fukushima, the country
committed to a complete nuclear phaseout, closing its last reactors in 2023. Public support for nuclear energy remains extremely low, and regulatory pathways for new nuclear builds are effectively blocked. That’s before we even get into the practicalities of siting, permitting,
insuring, and securing nuclear facilities in urban or semi-urban zones where hydrogen refueling infrastructure would plausibly be located. It’s like proposing to build a coal plant in the middle of Amsterdam to power electric scooters — technically possible, but politically suicidal and economically nonsensical.
But to understand why Germany is so allergic to nuclear, you have to understand the deeper
story of the Energiewende, Germany’s energy transition. It didn’t start in 2011 with Fukushima.
It started decades earlier, born out of a uniquely German mix of post-war anti-militarism,
environmental consciousness, and civic engagement. The anti-nuclear protests of the 1970s
weren’t fringe movements, they were formative. They helped shape political parties, most
notably the Greens, and built the cultural foundation for the country’s long-standing skepticism of nuclear energy. When Fukushima happened, it wasn’t a wake-up call for Germany, it was a confirmation of everything they already believed.
And here’s the thing: despite their nuclear exit, Germany has made enormous progress on
decarbonization. Their electricity mix now includes more than 50% from renewables,
dominated by wind and solar. They built the world’s largest solar industry (before China
undercut it), deployed tens of gigawatts of onshore and offshore wind, and invested heavily in grid infrastructure and storage. Per capita and against GDP, they emit far less CO₂ than most industrialized nations. Their carbon intensity of electricity has plummeted since the early 2000s, while industrial output remained robust. In short, Germany has done more of the hard work of decarbonization than most of its nuclear-hugging critics.
That doesn’t mean shutting down their nuclear plants was their best move. It wasn’t. Keeping
them online until their natural retirement age would have eased short-term energy price
spikes, especially during the Russian gas crunch. But the decision wasn’t made in a vacuum, and it wasn’t made by a government asleep at the wheel. It was the culmination of decades of cultural, environmental, and political alignment. If any country has earned the right to make that call, it’s the one that actually built a renewable-heavy grid and stuck with it through market ups and downs.
So for First Hydrogen to march into this context with a plan to pair nuclear technology Germany doesn’t want with hydrogen use cases it doesn’t need is more than tone-deaf, it’s
fundamentally incoherent. It misunderstands the culture, the policy, the economics, and the
actual energy system Germany has spent a generation building.
Then there’s the hydrogen problem itself. Hydrogen, for all its green branding, is an expensive
and inefficient energy carrier. Producing it via electrolysis requires vast amounts of electricity.
Storing it requires compression, liquefaction, or chemical conversion, all of which add cost and complexity. Transporting it is a logistical headache. Using it in vehicles loses 70 to 80% of the original energy. Add a nuclear reactor to the chain, and you’ve just stapled a megabucks solution to a kilobuck problem. It’s like powering your toaster with a jet engine. Sure, it works in
theory, but you’ll be out of money before the bread even gets warm.
And yet, if there’s one country where this kind of layered energy absurdity might get polite
applause instead of the deadpan stares it deserves, it’s Germany. Because while Germany has done many things right in its energy transition, it has also demonstrated a persistent, baffling irrationality when it comes to hydrogen.
This isn’t new. Michael Liebreich has been calling out the hydrogen hype for years. I’ve written
extensively about the groupthink — gruppendenken — that has gripped German energy policy circles, particularly in their obsession with hydrogen for end-use energy. Not for steelmaking or fertilizer — reasonable uses — but for heating buildings and driving cars and, now apparently, running vans on SMR-generated hydrogen. The evidence for this folly isn’t anecdotal, it’s in their modeling.
The dena-led Leitstudie Aufbruch Klimaneutralität (the German Energy Agency’s major
decarbonization pathway study) baked in hydrogen use at the end of every possible pipe. It
projected hydrogen-based heating, hydrogen transport, even hydrogen-based electricity
storage, despite the energy system losses stacking up like a Jenga tower made of burned
money. Similarly, the Prognos/PKI modeling , used in federal advisory processes, leaned heavily on magical hydrogen imports and vast, unexplained electrolysis buildouts, seemingly
unbothered by grid realities or cost curves.
These weren’t fringe speculations, they were foundational documents. Germany’s hydrogen
enthusiasm has created a policy environment where ideas that should be non-starters get
traction simply because they have the word wasserstoff in them. In that context, First
Hydrogen’s pitch to bring SMR-powered hydrogen production to Germany starts to make a
twisted kind of sense — not in physics, not in finance, but in the cultural logic of a country that,
for all its engineering rigor, still sometimes falls hard for the techno-utopianism of
overcomplicated solutions. It’s a country that earned its way to energy credibility with wind,
solar, and storage, and then occasionally turns around and tries to put a hydrogen jetpack on it for no good reason. So yes, the plan is absurd, but absurdity has a strange way of finding an audience where the right buzzwords meet the right policymaking blind spots.
And yet, First Hydrogen keeps raising small sums of money and announcing ever more
grandiose plans. In 2024, it closed tranches of convertible debentures amounting to a few
hundred thousand Canadian dollars, not enough to buy a single electrolyzer system, let alone fund a nuclear project. That’s on top of the roughly $9 million it has raised since 2020 which is supposed to fund a 35 MW electrolysis plant and a hydrogen delivery van manufacturing facility in Quebec as well.
The same company that hasn’t brought a product to market is now pitching itself as a future
builder of Europe’s nuclear-hydrogen infrastructure. The gap between vision and resources is
so wide you could drive their hydrogen prototype van through it and still have room for a
busload of skeptical engineers.
Balraj Mann, the founder, chair and CEO of First Hydrogen, had 20 firms he had founded,
owned, and was CEO of many of them when I looked at them a year ago. Now he’s added some more, and possibly has increased his $480,000 per year salary — just from First Hydrogen — based on this new international expansion. It’s convenient that these hydrogen plays appear to be a long way from his investors, reducing the likelihood of due diligence types actually looking at the lack of evidence of any there there.
What makes this spectacle more concerning is not that it exists — there are always hype-
chasers in clean tech — but that it continues to attract press coverage, grants, and in many
cases, government support. It raises a deeper question: why are we so willing to entertain the
layering of unproven technologies under the banner of innovation?
Hydrogen for energy plays keep failing and the countries into the first and biggest,
like Norway and Australia, are abandoning the space because it doesn’t make economic sense.
SMRs are decades away from commercial competitiveness, if they ever get there (unlikely),
more a form of intentional delay by right wing parties that can no longer just deny climate
change than an energy alternative. Stacking one onto the other doesn’t multiply opportunity, it multiplies uncertainty. Hydrogen with SMRs is such a classic case of multiplying hype that I
called it out specifically in my article from a couple of years ago, Two Wrongs Don’t Make A
Right: Adventures In Multiplying Hype.
In the end, First Hydrogen’s German SMR plan isn’t a moonshot, it’s a distraction. The world needs scalable, affordable, low-carbon solutions now. We have them: solar, wind, batteries,
grid interconnection, efficiency. Instead of doubling down on fairy dust, maybe it’s time we
started demanding fewer buzzwords and more kilowatt-hours. Until then, we’ll keep getting
pitches like this — powerpoint fantasies fueled by venture fumes and public confusion.
Swarms of satellites are harming astronomy. Here’s how researchers are fighting back

SpaceX and other companies plan to launch tens of thousands of satellites, which could mar astronomical observations and pollute the atmosphere.
Nature, By Alexandra Witze, 18 Mar 25
In the next few months, from its perch atop a mountain in Chile, the Vera C. Rubin Observatory will begin surveying the cosmos with the largest camera ever built. Every three nights, it will produce a map of the entire southern sky filled with stars, galaxies, asteroids and supernovae — and swarms of bright satellites ruining some of the view.
Astronomers didn’t worry much about satellites photobombing Rubin’s images when they started drawing up plans for the observatory more than two decades ago. But as the space around Earth becomes increasingly congested, researchers are having to find fresh ways to cope — or else lose precious data from Rubin and hundreds of other observatories.
The number of working satellites has soared in the past five years to around 11,000, mostly because of constellations of orbiters that provide Internet connectivity around the globe (see ‘Satellite surge’). Just one company, SpaceX in Hawthorne, California, has more than 7,000 operational Starlink satellites, all launched since 2019; OneWeb, a space communications company in London, has more than 630 satellites in its constellation. On paper, tens to hundreds of thousands more are planned from a variety of companies and nations, although probably not all of these will be launched1.
Satellites play a crucial part in connecting people, including bringing Internet to remote communities and emergency responders. But the rising number can be a problem for scientists because the satellites interfere with ground-based astronomical observations, by creating bright streaks on images and electromagnetic interference with radio telescopes. The satellite boom also poses other threats, including adding pollution to the atmosphere.
When the first Starlinks launched, some astronomers warned of existential threats to their discipline. Now, researchers in astronomy and other fields are working with satellite companies to help quantify and mitigate the impacts on science — and society. “There is growing interest in collaborating and finding solutions together,” says Giuliana Rotola, a space-policy researcher at the Sant’Anna School of Advanced Studies in Pisa, Italy.

Behind the hype -“New wave of smaller, cheaper nuclear reactors sends US states racing to attract the industry “

No modular reactors are operating in the U.S. and a project to build the first, this one in Idaho, was terminated in 2023, despite getting federal aid.
The U.S. remains without a long-term solution for storing radioactive waste
Nuclear also has competition from renewable energies.
New wave of smaller, cheaper nuclear reactors sends US states racing to attract the industry, By ASSOCIATED PRESS, 29 March 2025 https://www.dailymail.co.uk/wires/ap/article-14549543/New-wave-smaller-cheaper-nuclear-reactors-sends-US-states-racing-attract-industry.html
HARRISBURG, Pa. (AP) – With the promise of newer, cheaper nuclear power on the horizon, U.S. states are vying to position themselves to build and supply the industry’s next generation as policymakers consider expanding subsidies and paving over regulatory obstacles.
Advanced reactor designs from competing firms are filling up the federal government’s regulatory pipeline as the industry touts them as a reliable, climate-friendly way to meet electricity demands from tech giants desperate to power their fast-growing artificial intelligence platforms.
The reactors could be operational as early as 2030, giving states a short runway to roll out the red carpet, and they face lingering public skepticism about safety and growing competition from renewables like wind and solar. Still, the reactors have high-level federal support, and utilities across the U.S. are working to incorporate the energy source into their portfolios.
Last year, 25 states passed legislation to support advanced nuclear energy and this year lawmakers have introduced over 200 bills supportive of nuclear energy, said Marc Nichol of the Nuclear Energy Institute, a trade association whose members include power plant owners, universities and labor unions.
“We´ve seen states taking action at ever-increasing levels for the past few years now,” Nichol said in an interview.
Smaller reactors are, in theory, faster to build and easier to site than conventional reactors. They could be factory-built from standard parts and are touted as flexible enough to plunk down for a single customer, like a data center or an industrial complex.
Advanced reactors, called small modular reactors and microreactors, produce a fraction of the energy produced by the conventional nuclear reactors built around the world for the last 50 years. Where conventional reactors produce 800 to 1,000 megawatts, or enough to power about half a million homes, modular reactors produce 300 megawatts or less and microreactors produce no more than 20 megawatts.
Tech giants Amazon and Google are investing in nuclear reactors to get the power they need, as states compete with Big Tech, and each other, in a race for electricity.
For some state officials, nuclear is a carbon-free source of electricity that helps them meet greenhouse gas-reduction goals. Others see it as an always-on power source to replace an accelerating wave of retiring coal-fired power plants.
Tennessee Gov. Bill Lee last month proposed more than $90 million to help subsidize a Tennessee Valley Authority project to install several small reactors, boost research and attract nuclear tech firms.
Long a proponent of the TVA’s nuclear project, Lee also launched Tennessee’s Nuclear Energy Fund in 2023, designed to attract a supply chain, including a multibillion-dollar uranium enrichment plant billed as the state’s biggest-ever industrial investment.
In Utah, where Gov. Spencer Cox announced “Operation Gigawatt” to double the state’s electricity generation in a decade, the Republican wants to spend $20 million to prepare sites for nuclear. State Senate President J. Stuart Adams told colleagues when he opened the chamber’s 2025 session that Utah needs to be the “nation´s nuclear hub.”
Texas Gov. Greg Abbott declared his state is “ready to be No. 1 in advanced nuclear power” as Texas lawmakers consider billions in nuclear power incentives.
Michigan lawmakers are considering millions of dollars in incentives to develop and use the reactors, as well as train a nuclear industry workforce.
One state over, Indiana lawmakers this month passed legislation to let utilities more quickly seek reimbursement for the cost to build a modular reactor, undoing a decades-old prohibition designed to protect ratepayers from bloated, inefficient or, worse, aborted power projects.
In Arizona, lawmakers are considering a utility-backed bill to relax environmental regulations if a utility builds a reactor at the site of a large industrial power user or a retired coal-fired power plant.
Still, the devices face an uncertain future.
No modular reactors are operating in the U.S. and a project to build the first, this one in Idaho, was terminated in 2023, despite getting federal aid.
The U.S. Department of Energy last year, under then-President Joe Biden, estimated the U.S. will need an additional 200 gigawatts of new nuclear capacity to keep pace with future power demands and reach net-zero emissions of planet-warming greenhouse gases by 2050 to avoid the worst effects of climate change.
The U.S. currently has just under 100 gigawatts of nuclear power operating. More than 30 advanced nuclear projects are under consideration or planned to be in operation by the early 2030s, Nichol of the NEI said, but those would supply just a fraction of the 200 gigawatt goal.
Work to produce a modular reactor has drawn billions of dollars in federal subsidies, loan guarantees and more recently tax credits signed into law by Biden.
Those have been critical to the nuclear industry, which expects them to survive under President Donald Trump, whose administration it sees as a supporter.
The U.S. remains without a long-term solution for storing radioactive waste, safety regulators are under pressure from Congress to approve designs and there are serious questions about industry claims that the smaller reactors are efficient, safe and reliable, said Edwin Lyman, director of nuclear power safety at the Union of Concerned Scientists.
Plus, Lyman said, “the likelihood that those are going to be deployable and instantly 100% reliable right out of the gate is just not consistent with the history of nuclear power development. And so it´s a much riskier bet.”
Nuclear also has competition from renewable energies.
Brendan Kochunas, an assistant professor of nuclear engineering at the University of Michigan, said advanced reactors may have a short window to succeed, given the regulatory scrutiny they undergo and the advances in energy storage technologies to make wind and solar power more reliable.
Those storage technologies could develop faster, bring down renewables’ cost and, ultimately, make more economic sense than nuclear, Kochunas said.
The supply chain for building reactors is another question.
The U.S. lacks high-quality concrete- and steel-fabrication design skills necessary to manufacture a nuclear power plant, Kochunas said.
That introduces the prospect of higher costs and longer timelines, he said. While foreign suppliers could help, there also is the fuel to consider.
Kathryn Huff, a former top Energy Department official who is now an associate professor at the University of Illinois Urbana-Champaign, said uranium enrichment capacity in the U.S. and among its allies needs to grow in order to support reactor production.
First-of-their-kind reactors need to get up and running close to their target dates, Huff said, “in order for anyone to have faith that a second or third or fourth one should be built.”
DOE Reissues $900M Nuclear SMR Opportunity, Scraps Community Criteria to Focus on Technical Merit
Power, Mar 26, 2025, by Sonal Patel
The U.S. Department of Energy (DOE) has reissued a $900 million funding opportunity to accelerate deployment of Generation III+ small modular reactors (SMRs), removing community benefit requirements and shifting the focus solely to technical merit—a move that reflects the Trump administration’s revised energy and industrial priorities.
The funding opportunity announcement (FOA)—officially designated DE-FOA-0003485—was first issued in October 2024, backed by funds appropriated through the 2021 Infrastructure Investment and Jobs Act (IIJA) and authorized under the Consolidated Appropriations Act of 2024. The effort remains jointly administered by the Office of Nuclear Energy and the Office of Clean Energy Demonstrations (OCED), with technical support from the National Nuclear Security Administration (NNSA)……………………………………………………………………………………………………………………….
Community Requirements Dropped
According to the FOA, eligible Tier 1 projects must feature Generation III+ light-water reactor (LWR) designs ranging between 50 MWe and 350 MWe per unit. (To be considered, total plant output, including process heat loads, must be below 350 MWe.) Projects may involve single-unit or multi-unit configurations with no cap on total site output. Designs must meet a minimum Technology Readiness Level (TRL) of 6, signaling sufficient maturity for system-level validation and procurement.
The FOA also stresses that cost-sharing is a core requirement. “DOE cannot contribute more than 50% of the overall project cost; therefore, the total award value will be no less than $1.6 billion, if the full government share is awarded.” It adds that “DOE will pay out based on previously agreed milestone amounts upon their completion,” and that “the agreed upon milestone payment from DOE cannot account for more than 50% of the project costs incurred in completing the milestone.”………………………………………………………………………………………………………………………………………….
The most prominent change— as highlighted above—is that the March 24 submission formally eliminates all community benefit obligations that were central to the October 2024 solicitation. That includes the removal of the Community Benefits Plan, which had been a required five-page submission outlining how projects would support community and labor engagement, workforce investment, and equity objectives. It also eliminates the “Program Policy Factors” section, which the DOE previously used after technical review to prioritize projects based on geographic diversity, local job creation, engagement with disadvantaged communities, and alignment with broader social goals such as the Justice40 Initiative. The reissued FOA now states that “applications will be evaluated solely on technical merit.”……………………………………………………………………………………………more https://www.powermag.com/doe-reissues-900m-nuclear-smr-opportunity-scraps-community-criteria-to-focus-on-technical-merit/
The rush to war in space only needs a Gulf of Tonkin incident, and then what happens?

| Spacecom Protecting Homeland From Growing Threats March 26, 2025 | By David Vergun , https://www.defense.gov/News/News-Stories/Article/Article/4136285/spacecom-protecting-homeland-from-growing-threats/ |
The Defense Department must prepare for conflict in space to ensure deterrence. If that fails, the U.S. military is ready to fight and win, said Space Force Commander Gen. Stephen N. Whiting, who testified today at a Senate Armed Services subcommittee on strategic forces.
He said threats continue to expand at a breathtaking pace and pose a risk to the joint force.
The Defense Department must prepare for conflict in space to ensure deterrence. If that fails, the U.S. military is ready to fight and win, said Space Force Commander Gen. Stephen N. Whiting, who testified today at a Senate Armed Services subcommittee on strategic forces.
He said threats continue to expand at a breathtaking pace and pose a risk to the joint force.
Whiting said no other country can match the United States’ understanding of the complexities of space and the requirements to operate effectively in the most challenging areas of responsibility.
“Our military has the best trained, most capable space warfighting force in the world, and they stand dedicated to for America,” he added.
The general said Operation Olympic Defender is an example of working with allies and partners. He noted that Germany, France and New Zealand recently joined the United Kingdom, Canada and Australia as participating nations.
The operation’s mission optimizes space operations, improves mission assurance, enhances resilience and synchronizes efforts, according to a Spacecom news release.
This growth further strengthens partnerships and enables our allies to share the burden of collective space security, Whiting said.
“These advantages and our ability to deter potential adversaries cannot be taken for granted,” he said. “Deterrence in space is consistent with other domains. It requires a keen understanding and clear communication of what we are deterring against, credible, acknowledged capabilities to impose costs on those who attack us, and resilient architectures to dissuade attack by making any effort futile.”
Whiting said Spacecom is fully integrated into and contributing to the department’s efforts to establish a Golden Dome for American missile defense shield, adding that Space Command requires stable funding, as well as effective and efficient acquisition programs that deliver advanced space capabilities.
He identified the most pressing issues as the delivery of integrated space fires, enhanced battlespace awareness, and integrated command and control capabilities to achieve space superiority, which enhances homeland defense while protecting and enabling the joint force.
“Although many challenges lie ahead, the future of space holds tremendous promise for America if we actively and thoughtfully protect it,” he said.
In Whiting’s prepared testimony submitted to lawmakers, he wrote: “Spacecom is partnering with U.S. Northern Command and other stakeholders to write an initial capabilities document aimed at defining capability-based requirements for the Golden Dome architecture, based on forecasted threat scenarios. As these capabilities develop and deliver, we stand ready to take an active role in the operation of a next-generation space architecture which will be resident in our in support of protecting American citizens from attack.”
In his prepared testimony, he also addressed China’s views on space technology and its goal of becoming the dominant power in East Asia and a global superpower.
” seeks to rival the United States in nearly all areas of space technology by 2030 and establish itself as the world’s preeminent space power by 2045. Since 2015, China’s on-orbit presence has grown by 1,000%, with 1,094 active satellites as of January 2025. Its sophisticated space and counter-space systems enhance its ability to secure territorial claims, project power, and challenge U.S. advantages.”
Risk of Radiation Carcinogenesis

There is not currently thought to be a notable risk of a crewmember developing clinically detectable cancer during a mission due to spaceflight exposure.
Robert E. Lewis, NASA, 11 Mar 25, https://www.nasa.gov/directorates/esdmd/hhp/risk-of-radiation-carcinogenesis/
Increased radiation exposure in the spaceflight environment outside of low-Earth orbit may contribute to an increased risk of developing cancer later in an astronaut’s life. Shielding is effective against some radiation exposure, such as solar particle events (SPE) but does not mitigate Galactic Cosmic Radiation (GCR) exposure. Primary contributors to development of cancer later in life are dependent on mission parameters and duration, solar conditions, body structures present, individual radiosensitivity, and age at exposure. The effects of other sources of uncertainty that may modify radiation risk (e.g., secondary spaceflight hazards) are being characterized but cannot be estimated or integrated currently. Terrestrial cancer therapies continue to progress and may be able to mitigate cancer outcomes. There is not currently thought to be a notable risk of a crewmember developing clinically detectable cancer during a mission due to spaceflight exposure.
Delusional, ruinous and obsolete -the ITER nuclear fusion project

The ITER fusion project is 18 years late and can do nothing about climate change, writes Antoine Calandra
https://beyondnuclearinternational.org/2025/03/16/delirante-ruineuse-et-obsolete/
ITER (International Thermonuclear Experimental Reactor) is an international tokamak nuclear fusion research and engineering project, which has been significantly over budget and schedule, and is currently under construction next to the Cadarache nuclear facility in southern France.
India is one of the seven partner countries in the ITER project, along with the European Union, Russia, Japan, the United States, China, and South Korea. Macron may boast as much as he likes, but ITER is a complete fiasco, a delusional, ruinous, and obsolete project.
On November 14, 2024, the annual public meeting entitled: ITER, 15 years: what assessment? was held in Peyrolles.
I was expecting a big event and to get some recent information on the ITER construction site…But surprise, none of that!
A nondescript multipurpose room, no decor, no documents available, unpleasant white light, around forty people present, only interns (CEA ITER* employees, CLI members, local elected officials, a few union members)
For the event, the tables and chairs were arranged differently, “for a more convivial, cabaret-like atmosphere,” I heard. Oh!?
Pietro Barabaschi, Director General of ITER, was not there.
No agenda to announce the evening’s schedule with the names of the speakers, as in previous occasions. A very meager presentation of the ITER project (5 or 6 images) and that was it. And “time for questions from the audience.” Ah!
In short, the most pathetic ITER public meeting I have ever attended. A public meeting that reflects the ITER assessment.
ITER, what is the outcome?….a disaster!
We already wrote in 2005 with the MEDIANE association: “ITER, a dangerous, ruinous and doomed nuclear project”
The latest important news regarding ITER came on July 3, 2024, during the press conference of Pietro Barabaschi, the current ITER Director General, news that had been expected for a year.
A new calendar: 9 more years late!
The first plasma was originally scheduled for 2016, then postponed to 2025. It has been postponed to 2034. We are 18 years behind schedule.
And with the new calendar, an additional cost of €5 billion!
That’s at least €25 billion of public money to date, a cost multiplied by five. And in reality, more than €40 billion, including the in-kind contributions from the project’s partner countries.
The ITER Director acknowledged that “Fusion cannot come in time to solve the problems our planet faces today, and investments in other technologies, both known and unknown, are absolutely necessary.”
However, the speeches and commitments to get this nuclear fusion project accepted were completely different in 2006 at the time of this charade of public debate.
It was even possible to read that after ITER, DEMO, a pre-industrial demonstrator, was planned to “prove the industrial feasibility of this technology around 2040 and demonstrate that fusion can, by 2050, produce electricity on an industrial scale.”
Once again, the seven partner countries (the European Union, Russia, Japan, the United States, China, India, and South Korea) have agreed to pay more. But the ITER Director is now considering finding private actors to try to fill this financial gap.
Several private companies no longer expect anything from ITER, but they firmly believe in nuclear fusion and promise electricity production in a shorter timeframe.
Some even claim that ITER will be obsolete by the time it is commissioned.
I would add that ITER will probably not work and that there will never be industrial production of electricity through nuclear fusion.
Nuclear fusion will be neither “a revolution for humanity” nor “the energy of the future.”
It is not clean energy, nor even abundant energy. It is dangerous to human health and produces radioactive waste.
Its interest is above all military and to try to save the nuclear industry which has been in a bad state for several years.
ITER will probably never work and will end in total fiasco, worse than SuperPhénix*, which was supposed to be the flagship of the French nuclear industry.
But by squandering all these billions, the ITER monster will have succeeded in blocking any progress towards another energy model and imposing the continuation of the nuclear industry for years to come.
This myth of free and inexhaustible energy that allows for indefinite consumption and waste must be eradicated from people’s minds once and for all. It is also time to put an end to this gigantism and centralization of production in the hands of powerful, commanding states that serve the richest.
The solutions for the future have been known for a long time:
save energy, put an end to waste, develop and improve renewable energies (solar, wind, hydraulic) the only truly clean and future energies.
And not to develop them in an industrial and centralized manner, which is obviously and unfortunately the case.
The industrialization of the world must be fought. A new social project is a prerequisite for any energy project.
The future lies in small production units, local or regional, with technology accessible to the greatest number, low energy consumption, avoiding the cost of distribution.
Nuclear fusion, like fission, is a dangerous, dirty, and expensive energy source. It’s a complex, centralized technology reserved for wealthy countries, leading to proliferation, dependency, injustice, and war.

The Volunteer “Data Hoarders” Resisting Trump’s Purge
Can librarians and guerrilla archivists save the country’s files from DOGE?
New Yorker, By Julian Lucas, 15 Mar 25
The deletions began shortly after Donald Trump took office. C.D.C. web pages on vaccines, H.I.V. prevention, and reproductive health went missing. Findings on bird-flu transmission vanished minutes after they appeared. The Census Bureau’s public repository went offline, then returned without certain directories of geographic information. The Department of Justice expunged the January 6th insurrection from its website, and whitehouse.gov took down an explainer page about the Constitution. On February 7th, Trump sacked the head of the National Archives and Records Administration, the agency that maintains the official texts of the nation’s laws, and whose motto is “the written word endures.”
More than a hundred and ten thousand government pages have gone dark in a purge that one scientist likened to a “digital book burning,” and which has proved as frightening in its imprecision as in its malice……………………………………………………………………………………. (Subscribers only)

Book Review: How Our Digital Infatuation Undermines Discourse

In “Superbloom,” Nicholas Carr laments that we live in a state of uncontrollable sensory and communication overload.
By Elizabeth Svoboda, 03.14.2025, https://undark.org/2025/03/14/book-review-superbloom/?utm_source=Undark%3A+News+%26+Updates&utm_campaign=ecc4df9cbe-RSS_EMAIL_CAMPAIGN&utm_medium=email&utm_term=0_5cee408d66-185e4e09de-176033209
It was all Mother Nature’s fault, you could say. After winter rains in Lake Elsinore, California, reawakened countless dormant poppy seeds in early 2019, spring blossoms crowded in thickly enough to turn the hillsides bright orange — a fleeting “superbloom.” Recognizing an Instagrammable backdrop when she saw one, influencer Jaci Marie Smith reclined across the floral carpet in orange overalls and hit post. “You’ll never influence the world by trying to be like it,” her photo caption read.
In March, posts like Smith’s and #superbloom hashtags fueled a global frenzy. So many sightseers and influencers crowded into Lake Elsinore, snarling traffic and pulling up blooms by the handfuls, that officials declared a public safety emergency. As residents and others ripped into influencers for unleashing viral havoc on the small town, some took down their poppy posts, while others offered excuses and mea culpas. A meme that had begun in innocent enthusiasm curdled in an internet minute, setting people against each other and leaving a wake of real-world destruction.
We’re living in a perpetual digital superbloom, contends technology writer Nicholas Carr — a state of sensory and communication overload we can no longer control, one that’s sowing division and damage on a global scale. And like the poppy field that hypnotized Dorothy’s “Wizard of Oz” crew, this social media-fueled superbloom lures us in with enticements that are nearly impossible to resist. “Poppies are lush, vibrant, and entrancing,” Carr writes in “Superbloom: How Technologies of Connection Tear Us Apart.” “They’re also garish, invasive, and narcotic.”
This is familiar ground for Carr — at least, as familiar as any fast-morphing digital terrain can be. Carr’s stance as a techno-skeptic has been consistent for decades, though it’s evolved as digital communication modes have bloomed and receded. His 2010 book “The Shallows”, a finalist for the Pulitzer Prize, argued that the online world is distracting and prevents deeper engagement with texts, and he followed that up in 2014 with “The Glass Cage,” a reflection on how interacting with our computers changes us.
In “Superbloom,” Carr expands on a central theme of “The Glass Cage”: While we view our digital devices as helpers serving up knowledge and entertainment, they exact an unacknowledged toll in the process, altering how we think, act, and communicate. We are far different humans in an era of texting, posting, and like-seeking, Carr argues, than we were when limited to letters and phone calls — and not for the better.
He contends that when we communicate mostly in one-line messages and hot takes, the kind that titillate and propagate from one human node to the next, our capacity to engage more intently and thoughtfully withers. “What we sacrifice are depth and rigor,” he writes. Thus, “we rely on quick and often emotional judgments while eschewing slower, reflective ones.”
This is a fair point, if only true in some online contexts: Masters of the 140-character social media quip win plenty of fans elsewhere with their books and long essays. What’s more convincing is Carr’s analysis of why our instant access to one another online, which we often assume is an advantage, has led to more social breakdown rather than less.
……………………………………in virtual space, “we’re all in one another’s business all the time,” Carr writes, later adding, “With an almost microscopic view of what everybody else is saying and doing — the screen turns us all into peeping Toms — we have no end of opportunities to take offense.”
……………….Carr’s vivid, jargon-free prose hits right in the solar plexus. “We’re not hostages with Stockholm syndrome,” he writes of our relationship with social media. “We’re being given what we want, in quantities so generous we can’t resist gorging ourselves.”
…………………However hard-hitting and sound its claims, “Superbloom” might feel too apocalyptic were it not for Carr’s closing plea to hold the line. He says it’s too late to change the online systems we’re embedded in — a judgment that seems a tad dour, given how rapidly those same systems have themselves changed over time. But he rightly notes that to peel away from a virtual world that’s more image than substance, users must deliberately resist its empty charms, much as the rebels of Aldous Huxley’s “Brave New World” rejected the happiness drug soma.
…….. he calls for judicious online withdrawal rather than Luddite-style divestment, for staking out a position “not beyond the reach of the informational flow, but beyond the reach of its liquefying force.”
While digital pessimists can come across as Cassandra-like, their warnings have never been more resonant. For Carr, the rough online beast is no longer merely slouching in our direction. It’s already devouring us. “Superbloom” frames the choice ahead in the starkest possible terms: Do we consent to being swallowed, or find a way — however quixotic and improbable — to escape the maw?

Elon Musk Announces ‘Massive Cyberattack’ Causing X Outage
Thousands of people reported on March 10 that the social media platform was down for them.
Epoch Times, 3/10/2025By Jack Phillips
Tech billionaire Elon Musk on March 10 said that an outage affecting his social media platform, X, is being caused by a “massive cyberattack” that is ongoing.
On March 10, tens of thousands of reports were submitted to DownDetector saying users could not access the X app or website or they could not access posts.
In response, Musk wrote at midday: “There was (still is) a massive cyberattack against X. We get attacked every day, but this was done with a lot of resources.”
“Either a large, coordinated group and/or a country is involved,” the Tesla and SpaceX CEO wrote, adding that his company is “tracing” the attacks.
In a later interview with Fox News on the same day, Musk said that the attacks’ IP addresses in the X cyberattack were “linked to IP addresses originating in the Ukraine area.” The Epoch Times could not immediately authenticate Musk’s comment.
People on the platform first started reporting issues after 5 a.m. ET on March 10, according to DownDetector. After a brief period of time, the number of reports appeared to drop before picking back up again at about 11 a.m. ET……………………………………
More than 10,000 people in the United Kingdom also reported an X outage earlier on March 10, according to DownDetector’s website…………………..
The outage comes amid Musk and Secretary of State Marco Rubio having publicly sparred with Polish Foreign Minister Radoslaw Sikorski on March 9 after Musk said on X that the Ukraine war with Russia would be severely hampered if he were to turn off Starlink internet access in the Eastern European country.
On March 9, Musk, who is currently a senior adviser to President Donald Trump, wrote that Starlink has served as the “backbone of the Ukrainian army” and asserted that “their entire front line would collapse if I turned it off.” He also said he wants peace for Ukraine and that he’s backed the country in its war effort by providing the internet service.
Sikorski responded to Musk by saying that Poland was paying for the internet service and claimed Musk was threatening Kyiv. The Trump administration and Ukraine’s leadership have been engaged in high-stakes talks about ending the conflict and a deal for continued support of Ukraine that also benefits the United States………. https://www.theepochtimes.com/us/elon-musk-announces-massive-cyberattack-causing-x-outage-5823029?utm_source=Aobreakingnoe&utm_medium=Aoemail&utm_campaign=Aobreaking-2025-03-11&utm_content=NL_Ao&src_src=Aobreakingnoe&src_cmp=Aobreaking-2025-03-11&cta_utm_source=Aobreakingnoecta&est=iIzbjUv5GHdVOivdisxCzrbEBMMMNm2pOhOa%2F2%2Bo%2B8Uc84LMJe%2BVuIounSiENahxKSKfQOBK8pkU
Failure After Failure: Let’s Ditch Small Modular Reactors.

The World Mind, February 25, 2025, Carmine Miklovis https://www.theworldmind.org/briefing-archive/failure-after-failure-lets-ditch-small-modular-reactors2025/2/25
Imagine a revolutionary new coffee machine – one that can get twice as much coffee from the same amount of beans. This machine would make coffee cheaper to make at home and buy at shops like Dunkin’ and Starbucks. This coffee machine starts to get buy-in from major companies in the coffee business, like Keurig and Nespresso, and is projected to be launched in Summer 2025. Halfway through the spring, it’s announced that, due to delays, it will now be launched in Winter 2027. After another delay, it’s announced that the project is now expected by 2030. Keurig and Nespresso, in response, withdraw from the project, further delaying it until 2035. After 10 years of delays, would you still invest in this machine? Probably not, so why are we investing in an energy technology that’s built on the same promises?
Small modular reactors (SMRs), unlike the coffee machine, are a real technology that promise to make nuclear energy cheaper and more accessible. In theory, their smaller size allows them to be deployed more quickly and in a variety of settings, an advantage over solar panels, wind turbines, and tidal energy, which have location restrictions. Some of these reactor designs can reprocess spent fuel (known as a “closed fuel cycle”) to extract more energy than traditional reactors can from the same amount of fuel. As such, many have hailed these nuclear reactors as the key to addressing the climate crisis, as they seem to resolve a lot of the current problems that have plagued nuclear power thus far.
On an international level, France and India have announced plans to begin constructing SMRs together, praising the energy source for its potential to enable the transition to a low-carbon future. India is also expected to work with U.S. firms to enhance investment in the technology. Similarly, Trump’s pick for energy secretary, Chris Wright, served on the board of Oklo Inc., a company that focuses on advanced nuclear technology, and is pushing for investments in nuclear energy (alongside fossil fuels). As the Trump administration ditches renewables for fossil fuels and nuclear energy, some, including Wright, have said that now is the time for the nuclear renaissance.

Unfortunately, however, it seems increasingly likely that these reactors will fail to live up to their promise. Talks of deploying small modular reactors have been ongoing for over a decade, and while around a hundred designs exist, only two reactors have been deployed–one in China and one in Russia. In the U.S., while private companies and the federal government have invested billions into their development, projects have faced delays and cancellations. Long construction times, issues with quality control, and disproportionately high energy costs (for producers and consumers alike) have led many to conclude that the energy source is a false promise. Recognizing this failure, many of the largest energy companies, such as Babcock & Wilcox and Westinghouse have withdrawn their investments, leaving many other investors hesitant to put any of their assets in the nuclear cause. While the potential of these models is exciting in theory, investors would much rather hedge their bets on just about anything else.

To make matters worse, small modular reactors come with an additional catch: they risk enabling the proliferation of nuclear weapons. SMRs are a dual-use technology; after reactors have extracted energy from the fuel rods (the real-life equivalent of the coffee beans from earlier), they’re left with weapons-grade plutonium in the nuclear waste that could be used to create a potent nuclear weapon. This risk is particularly acute for reactors that reprocess for more energy, as the leftover waste is more potent and more viable for a nuclear weapon.
This presents a particular challenge, as in order for the touted benefits of SMRs to materialize, they need to distinguish themselves from the nuclear reactors we have now. As such, these new designs have to be more efficient and take advantage of their versatility, which means a lot of smaller reactors capable of reprocessing. More fissile material (in quantity and quality) coming out of more reactors makes it difficult to effectively monitor where all the waste goes. To complicate things, monitoring is already a problem, as it’s difficult to accurately measure nuclear material as it’s being transported from the facility to a waste disposal unit. The ease of diverting material could provide a pathway for states that have long had nuclear ambitions, such as Iran (who is also in a proxy war against a nuclear-armed adversary), or opportunistic non-state actors (such as domestic extremists or terrorist groups like ISIS) to finally get their hands on a nuclear weapon.

Unfortunately for proponents, it’s unlikely that the U.S. will be able to control or monitor the spread of this technology. The U.S. cannot set the standards for SMRs when it continues to lag behind Russia and China in production. Even then, why would countries already in China’s global infrastructure program, known as the Belt and Road Initiative, choose to get nuclear reactor designs from the U.S. further down the line when they can get nuclear reactors from China now? Chinese energy technology is likely more interoperable—able to work with pre-existing infrastructure—than U.S. designs, further restricting the U.S.’ potential market share. Even our closest allies wouldn’t want U.S. models, as some of them, including Germany and Japan, have given up on nuclear energy altogether. Given this hesitation and the long delays, SMRs would either fail to be deployed at a sufficient scale to resolve climate change, or would be completed hastily, which increases the risk of state or non-state actors acquiring a nuclear weapon.
While some may argue that any investment in renewable energy is a net positive in the fight against climate change, investing in nuclear energy hamstrings the response of future administrations. Investing in nuclear power creates a dangerous moral licensing, wherein future leaders may feel less incentivized to invest in other, effective renewable energy sources because they feel that they already have it covered with nuclear power. Historically, because of the way subsidies are distributed under the Clean Power Plan, nuclear energy actively stifles the development of other energies. In an effort to make nuclear power prices competitive, the U.S. government subsidizes it, which actively siphons those subsidies away from solar, wind, and tidal energy. As solar energy becomes the cheapest option available, subsidies to expand its gap or aid its clean partners could enhance renewable energy’s grip on the market. Absent these subsidies, however, fossil fuels may retain their foothold in the market for the foreseeable future. Given the existential threat at stake, the risk that this poses for the climate response cannot be overstated.

While advocates of SMRs are right that renewable energy needs to be adopted swiftly, trying to haphazardly rush out these reactors to deploy around the world risks trading one crisis for another, enabling a new era of nuclear proliferation. Similarly, if the Trump administration wants to keep its promise of low energy prices, their best bet is to stop investing in the nuclear power industry and let solar and wind energy take the reins. Like the hypothetical coffee machine, the benefits of SMRs will remain a nice thought, but nothing more than that. As climate change beckons at our doorstep, we can’t afford to invest in a false promise—it’s time to ditch SMRs.
The SMR Gamble: Betting on Nuclear to Fuel the Data Center Boom

“Who’s going to insure these plants?” “That’s a huge unknown. “
Mar 3, 2025, by Sonal Patel Power Mag
Data center power demand is accelerating, pushing the grid to its limits and prompting tech giants to bet on next-generation nuclear reactors. But given steep costs, regulatory hurdles, and uncertain scalability, is nuclear the future of data center energy—or just another high-stakes gamble?
At the end of January, Chinese artificial intelligence (AI) startup DeepSeek unveiled two large language models (LLMs)—DeepSeek-R1 and DeepSeek-R1-zero. Unlike previous generations of AI models, DeepSeek’s breakthrough reduced the compute cost of AI inference by a factor of 10, allowing it to achieve OpenAI GPT-4.5-level performance while consuming only a fraction of the power.
The news upended future electricity demand assumptions, rattling both the energy and tech sectors. Investment markets reacted swiftly, driving down expectations—and share prices—for power generation, small modular reactor (SMR) developers, uranium suppliers, gas companies, and major tech firms.
Yet, amid the chaos, optimism abounded. Analysts pointed to Jevons paradox, the economic principle that efficiency gains can increase consumption, rather than reduce it. “Our model shows a ~90% drop in the unit cost of compute over a six-year period, and our recent survey of corporate AI adoption suggests increases in the magnitude of AI use cases,” said Morgan Stanley Research. The U.S. remains the dominant market for AI-driven data center expansion, with 40 GW of new projects under development, aligning with a projected 57 GW of AI-related compute demand by 2028. Already, that load is transforming the energy landscape. A recent POWER analysis shows that U.S. data center electricity consumption could reach between 214 TWh and 675 TWh annually by 2030, up from 176 TWh in 2023 (Figure 1 on original)………………………………
Emerging Business Challenges
Still, beyond regulations, the actual business of running co-located nuclear plants remains uncertain. While recent discussions highlight tech companies as potential investors in advanced nuclear facilities, data center sources confirmed most aren’t attracted to the prospect of owning and operating nuclear plants.
“Data center operators are not in the business of running power plants,” said Walsh. “They want reliability and cost certainty, but they don’t want to deal with regulatory oversight, fuel procurement, or reactor maintenance.”………………………
From an operational standpoint, co-located facilities can pose new risks, as Nina Sadighi, professional engineer and founder of Eradeh Power Consulting told POWER. “Who’s going to insure these plants?” she asked. “That’s a huge unknown. Right now, insurance providers are hesitant because of the regulatory and operational complexity. The traditional nuclear liability structures are built around large reactors with established operational histories, and when you introduce something novel like SMRs or microreactors, you’re dealing with a very different risk profile.”
Sadighi, though generally optimistic about nuclear’s suitability for data centers, also pointed to potential workforce-related challenges that hinge on timely deployment. “If we train nuclear workers now, but deployment gets delayed, those workers won’t wait around,” she said. “The nuclear workforce pipeline is not like a tech workforce, where people can pivot between roles quickly. These are specialized skills that require years of training, and if there’s uncertainty about job stability, we risk losing them to other industries entirely,” she said. Sadighi also raised concerns about the stringent operational protocols that add to labor inefficiencies.
Finally, while the data center industry isn’t solely bent on economics—and told POWER sustainability with a long-term vision is a bigger priority—scaling up will require significant investment. That has sparked all kinds of debate. Lux Research estimates first-of-a-kind (FOAK) SMRs could cost nearly three times more than natural gas ($331/MWh versus $124/MWh) and more than 10 times more when factoring in cost overruns and delays. The firm projects SMRs won’t be cost-competitive before 2035. “Cheap nuclear just isn’t in the cards in the next two decades,” it says.
The fundamental debate is rooted in several uncertainties—which is not uncommon for emerging sectors, experts also generally pointed out. “Tax credits—especially the clean electricity production tax credits and investment tax credits—will be vital to the commercial viability of these projects, especially considering the FOAK risk,” said Teplinsky. “DOE [U.S. Department of Energy] loan guarantees and direct financing from the Federal Financing Bank at low rates are also essential to companies’ ability to secure debt and reduce cost of capital. Grant funding to support commercial demonstrations and high-assay low-enriched uranium support are also key.” ………………..

Small modular reactor plans edge closer, amid claims that the technology makes no economic sense

By Simon Hacker, Punchline Gloucester 28th Feb 2025
…………………………………….Dale Vince, the owner of Stroud-based green energy group Ecotricity, has
roundly condemned the technology for “defying the economic laws of
gravity”.
Speaking on his weekly Zerocarbonista podcast, Mr Vince said:
“When you come to small nukes, the government and the nuclear industry have
consistently said that we will get lower bills, but they don’t put a number
on it. They are ecomonists without numbers!
Energy minister Ed Miliband: keen to move ahead on SMR plans. Big nuclear is the most expensive electricity we have ever made, it’s off the charts compared to renewable
energy and one of the fundamental laws of physics is that the economies of
scale come by making something bigger, not by making something smaller –
it always costs money to miniaturise.
So here they are, saying we can
miniatarise nuclear reactors that famously went decades late and billions
over budget… and they’ll be cheap. I don’t believe that for a second and
what we are of course doing is proliferating the risk.”
He added: “It’s always worth imagining what it would be like if the Romans had nuclear
power. If they did, Bath would be a toxic no-go zone. It’s only 2,000 years
ago and sounds like a long time, but not in the context of toxic nuclear
waste.” Whether Berkeley and neighbouring site Oldbury-on-Severn progress
with Rolls Royce’s SMR bid, the technology’s pathway to viable commercial
models for energy production remains challenging: as of today, only China
and Russia have operational SMRs, with China’s HTR-PM pebble-bed reactor
connected to the grid and Russia’s floating Akademik Lomonosov plant
utilizing two 35MW SMRs. https://www.punchline-gloucester.com/articles/aanews/smr-plans-edge-closer-amid-claims-the-technology-makes-no-economic-sense
