Small Modular Nuclear Five Times The Price (letter)
by News Of The Area – Modern Media –
DEAR News Of The Area,
IN response to Derek Musgrove opinion regarding small modular nuclear generation.
Derek, the reason nuclear sub reactors are not used for domestic generation is because they use a more enriched fuel unsuitable for domestic SMRs.
If you research your topic for five minutes you will find only five SMRs operating in the world.
There are quite a number in development but they are either abandoned or going to produce power at five times the cost of other types of generation.
Nuclear power also needs huge amounts of water for cooling so it limits their location options.
Feel free to check these facts.
Not scaremongering but why would we want to pay five times the cost for power.
The reactor in Canada is heavily subsidised by their government.
While you fact check, search how many SMRs would Australia need.
Did you know in 2023 in South Australia 80 percent of their power generation was from renewables.
Regards,
Ian HALL,

Sam Altman-backed nuclear start-up crashes after Wall Street debut
NEW YORK, https://www.malaymail.com/news/money/2024/05/11/sam-altman-backed-nuclear-start-up-crashes-after-wall-street-debut/133694 ― The share price of nuclear energy start-up Oklo, chaired by OpenAI boss Sam Altman, fell sharply yesterday on its first day of trading on Wall Street.
At around 3.40pm (1940GMT), the stock was down 53.9 per cent to US$8.40 (RM39.80).
Founded in 2013 by graduates of the Massachusetts Institute of Technology (MIT), Oklo went public by merging with AltC Acquisition Corp, a listed company.
The latter is a SPAC (special purpose acquisition company), a company whose sole purpose is to enable another firm to enter Wall Street through a merger.
Since the deal with Oklo was announced in July last year, AltC’s share price has soared, gaining over 72 per cent.
But transactions involving a SPAC are often highly volatile, partly because they are more exposed to speculation than traditional IPOs.
Altman is involved in several cutting-edge sectors and invested in Oklo in 2015, also becoming its chairman.
According to company documents, Altman directly controls around three per cent of the capital.
Oklo plans to build small modular reactors (SMRs), which are theoretically quicker to build than conventional power plants and less complicated to construct in remote areas. Oklo also wants to offer nuclear fuel recycling.
Conventional nuclear reactors are hugely expensive and take a long time to construct, with major projects having become notorious for their budget and schedule overruns.
The startup does not yet have a site of its own, and in January 2022 was refused a licence to build an SMR in Idaho by the Nuclear Regulatory Agency (NRC).
The NRC rejected the application on the grounds that there was a lack of information on the risks of accidents and the responses planned in such cases.
With the merger with AltC, Oklo raised US$306 million, which will be used to build the company’s first fission reactor, Aurora, in Ohio. ― AFP
South Korean state energy monopoly in talks to build new UK nuclear plant.
Kepco has held early-stage discussions with British officials over
mothballed Wylfa site. South Korea’s state energy monopoly is in talks
with the UK government about building a new nuclear power station off the
coast of Wales, in what could be a big boost to Britain’s plans for a new
nuclear fleet.
Kepco has held early-stage discussions with British
officials about a new facility at the Wylfa site in Anglesey, and a
ministerial meeting is expected this coming week, according to people
briefed on the matter.
In his March Budget, chancellor Jeremy Hunt
announced the government would buy the mothballed site and another from
Hitachi for £160mn. In 2019, the Japanese industrial group scrapped its
plans to develop a nuclear project at Wylfa, writing off £2.1bn in the
process.
Hunt’s move was designed to facilitate a fresh deal with a new
private sector partner to build a power station at Wylfa, which could boost
the government’s plans to replace Britain’s current ageing fleet of
nuclear power stations.
A consortium including US construction group
Bechtel and US nuclear company Westinghouse has already proposed building a
new plant on the Wylfa site using Westinghouse’s AP1000 reactor
technology.
Another industry figure said Wylfa’s future would depend on a
decision by GB Nuclear, the government quango which now owns the site. GBN
could give the go-ahead for a large reactor or reactors at Wylfa or judge
that it is a suitable site for building a cluster of new “small modular
reactors”.
Supporters of SMRs claim their modular design would make them
relatively quick and cheap to build. “Wylfa is now the next priority site
for the UK so it makes sense that Kepco are interested, but they just need
GBN to make a decision soon about whether they do want a traditional
nuclear power station there,” the figure said.
One senior Korean
government official struck a cautious note about the prospect of Kepco
buying the site, saying that building nuclear power stations in the UK was
“difficult”.

France’s mini nuclear reactor plan – Nuward, gets another financial handout from the European Commission
The European Commission (EC) has approved, under European Union (EU) state
aid rules, a €300m ($320m) French measure to support Electricité de
France’s (EDF) subsidiary Nuward in researching and developing small
modular nuclear reactors (SMRs). The EC said the measure will contribute to
the achievement of the strategic objectives of the European industrial
strategy and the European Green Deal.
France notified to the Commission its
plan to grant €300m to Nuward to support its research and development
(R&D) project on SMR technology. The project aims to develop processes for
the design and construction of SMRs based on a simple and modular design
and with a power output equivalent to or less than 300 MWe. The front-end
design is the third phase of the overall Nuward project, which contains
five distinct phases.
In December 2022, the Commission already approved a
€50m French measure to support the second phase of the project, aimed at
acquiring new knowledge for the design and construction of SMRs. The aid
will take the form of a direct grant of up to €300m that will cover the
R&D project until early 2027. The measure will support Nuward in sizing the
modules and components of the SMRs and validating their integration in the
SMRs by means of numerical simulators and laboratory tests. Nuward will
also carry out industrialisation studies relating to the modular design and
mass production of SMRs. Finally, the measure will also support Nuward in
the preparation of the required safety demonstrations for the approval of
the project by the national nuclear safety authorities.

Small reactors don’t add up as a viable energy source
By M.V. Ramana and Sophie Groll. 6 May 24, https://cosmosmagazine.com/science/engineering/small-reactors-dont-add-up/
The nuclear industry has been offering so-called Small Modular Reactors (SMRs) as an alternative to large reactors as a possible solution to climate change.
SMRs are defined as nuclear reactors with a power output of less than 300 megawatts of electricity, compared to the typically 1000 to 1,500 megawatts power capacity of larger reactors.
Proponents assert that SMRs would cost less to build and thus be more affordable.
However, when evaluated on the basis of cost per unit of power capacity, SMRs will actually be more expensive than large reactors.
This ‘diseconomy of scale’ was demonstrated by the now-terminated proposal to build six NuScale Power SMRs (77 megawatts each) in Idaho in the United States.
The final cost estimate of the project per megawatt was around 250 percent more than the initial per megawatt cost for the 2,200 megawatts Vogtle nuclear power plant being built in Georgia, US.
Previous small reactors built in various parts of America also shut down because they were uneconomical.
The high cost of constructing SMRs on a per megawatt basis translates into high electricity production costs.
According to the 2023 GenCost report from the Australian Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the Australian Energy Market Operator, the estimated cost of generating each megawatt-hour of electricity from an SMR is around AUD$400 to AUD$600.
In comparison, the cost of each megawatt-hour of electricity from wind and solar photovoltaic plants is around AUD$100, even after accounting for the cost involved in balancing the variability of output from solar and wind plants.
Building SMRs has also been subject to delays. Russia’s KLT-40 took 13 years from when construction started to when it started generating electricity, instead of the expected three years.
Small reactors also raise all of the usual concerns associated with nuclear power, including the risk of severe accidents, the linkage to nuclear weapons proliferation, and the production of radioactive waste that has no demonstrated solution because of technical and social challenges.
One 2022 study calculated that various radioactive waste streams from SMRs would be larger than the corresponding waste streams from existing light water reactors.
The bottom line is that new reactor designs, such as SMRs, will not rescue nuclear power from its multiple problems. Any energy technology that is beset with such environmental problems and risks cannot be termed sustainable.
Nuclear energy itself has been declining in importance as a source of power: the fraction of the world’s electricity supplied by nuclear reactors has declined from a maximum of 17.5 percent in 1996 down to 9.2 percent in 2022. All indications suggest that the trend will continue if not accelerate.
The decline in the global share of nuclear power is driven by poor economics: generating power with nuclear reactors is costly compared to other low-carbon, renewable sources of energy and the difference between these costs is widening.
Nuclear reactors built during the last decade have all demonstrated a pattern of cost and time overruns in their construction.
The Vogtle nuclear power plant being built in Georgia, involving two reactors designed to generate around 1,100 megawatts of electricity each, is currently estimated to cost nearly USD$35 billion.
In 2011, when the utility company building the reactor sought permission from the American Nuclear Regulatory Commission, it projected a total cost of USD$14 billion, and ‘in-service dates of 2016 and 2017’ for the two units.
In France, the 1,630-megawatt European Pressurised Reactor being built in Flamanville was originally estimated to cost 3 billion euros and projected to start in 2012, but the cost has soared to an estimated 13.2 billion euros and is yet to start operating as of March 2024.
These cost increases and delays confirm the historical pattern identified in a study published in 2014: of the 180 nuclear power projects around the world it studied, 175 had exceeded their initial budgets, by an average of 117 percent, and took 64 percent longer than initially projected.
However, the recent projects are even more extreme in the magnitude of the disconnect between expectations and reality.
These reactor projects, and the Hinkley Point C project under construction in the United Kingdom, also confirm another historical pattern: costs of nuclear power plants go up with time, not down. This is unlike other energy technologies, such as solar and wind energy, where costs have declined rapidly with experience.
The climate crisis is urgent. The world has neither the financial resources nor the luxury of time to expand nuclear power. As physicist and energy analyst Amory Lovins argued: “… to protect the climate, we must save the most carbon at the least cost and in the least time.”
Expanding nuclear energy only makes the climate problem worse.
The money invested in nuclear energy would save far more carbon dioxide if it were instead invested in renewables.
And the reduction in emissions from investing in renewables would be far quicker.

Why UK Government nuclear quango has ruled out Trawsfynydd from initial mini-nuke rollout
The site in Gwynedd could still be considered later on in the process
Owen Hughes, Business correspondent, 3 MAY 2024
A UK Government nuclear quango has dropped Trawsfynydd from the initial rollout of small modular reactors. Former Prime Minister Boris Johnson had said in 2022 that the UK Government are “looking to build another small modular reactor(SMR) on the site at Trawsfynydd”.
The Nuclear Decommissioning Authority (NDA) and Welsh Government owned Cwmni Egino had been working up plans for a new nuclear station close to the former power station, which stopped generating in 1991 and is in the long process of being decommissioned. The location had also previously been tipped by Rolls Royce SMR as a location for an SMR.
But those hopes have been dealt a blow after Great British Nuclear(GBN) said the site would not be considered in its initial rollout phase. It is understood the size of the site and the volume of cooling water counted against it. They also said it may not be able to deploy as quickly as some other sites.
It has though not been ruled out completely and could play a part in the future. A source explained that the initial rollout was looking at locations that could host four or five SMRs, which Traws does not have capacity for.
But once these larger sites are developed a further rollout would consider smaller sites that could host one or two SMRs, with would put the Gwynedd site back in contention.
On Anglesey, UK Government is buying the Wylfa site in a bid to progress nuclear development on the island after two failed attempts for a Wylfa B. This could be used for four or five SMRs or a single large scale nuclear power station…………………………………
GBN’s plans for its first phase of work for SMRs proposes to make decisions on investments by 2029, with power on the grid by the mid-2030s. https://www.dailypost.co.uk/news/north-wales-news/uk-government-nuclear-quango-ruled-29108206
TODAY. Small modular reactors – yes -the nuclear lobby will keep hyping them – no matter what!
Well, we all do know why. The small nuclear reactor (SMR)power industry – moribund though it is, is essential for the nuclear weapons industry – for a number of reasons, but importantly – to put a sweet gloss on that murderous industry.
Never mind that USA’s NuScale’s SMRs were a resounding flop – NuScale is still being touted, along with all the other little nuclear unicorns manouvreing to get tax-payer funding.
The facts remain, and apparently just need to be hammered again and again:
SMRs are not cheap, not safe, do not reduce wastes, are not reliable for off-grid power, are not more efficient fuel users than are large reactors.
The latest hyped -up push for SMRs is in Canada – with the boast that they will benefit indigenous communities . Successful bribery of indigenous people would give a huge boost to the global nuclear lobby, – as indigenous people have historically been the most distrustful of uranium mining and of the whole nuclear fuel chain.
The gimmicks this time are floating nuclear power plants – barges carrying Westinghouse’s eVinci microreactors. These would take over from the current deisal power plants serving remote communities. There are already some solar, wind and battery projects – frowned upon by the nuclear lobby, of course.
These projects are being strongly promoted, but poorly explained to indigenous communities, would bring radiological hazards along Canada’s Northern shoreline
And what really are the chances that these little nuclear power sources would be effective anyway? Recent reports by the International Atomic Energy Agency (IAEA) reveal that while 83 small nuclear reactors are “in development”, but there are only 2 in operation.
In both cases, the development of the reactors was a very lengthy and expensive process.
The Chinese SMR HTR-PM- “Between January and December 2022, the reactors operated for only 27 hours out of a possible maximum of 8,760 hours. In the subsequent three months, they seem to have operated at a load factor of around 10 percent.”
For the Russian SMR – “The operating records of the two KLT-40S reactors have been quite poor. According to the IAEA’s PRIS [Power Reactor Information System] database, the two reactors had load factors of just 26.4 and 30.5 percent respectively in 2022, and lifetime load factors of just 34 and 22.4 percent.”
Will Canada’s remote indigenous communitites buy the duplicitous nuclear lobby’s propaganda on SMRs ? And then, subsequently, will the rest of us buy it, despite the facts. I guess that the corporate media will help, – if lies are repeated often enough, people come to believe them.
Small modular reactors aren’t the energy answer for Canada’s remote communities and mines
The energy costs associated with small modular reactors exceed those of diesel-based electricity. Policy-makers should focus on renewables.
by Sarah Froese, Nadja Kunz, M. V. Ramana August 26, 2020 https://policyoptions.irpp.org/magazines/august-2020/small-modular-reactors-arent-the-energy-answer-for-remote-communities-and-mines/
A new type of theoretical nuclear power plant design called small modular reactors (SMRs) has been in the news of late. Earlier this year, at the 2020 Canadian Nuclear Association conference, Minister of Natural Resources Seamus O’Regan announced that the federal government will release an SMR Action Plan this fall. Ontario, New Brunswick and Saskatchewan have announced their backing and possibly some financial support for the development of these reactors.
Promoters suggest that remote communities and off-grid mining operations are promising markets for SMRs in Canada. These communities and mines pay a lot for electricity because they are reliant on diesel generators, and transporting and storing diesel to these locations can be very expensive. Thus, supporters hope, SMRs might be a way to lower electricity costs and carbon dioxide emissions.
We examined this proposition in detail in a recently published paper and concluded that this argument has two problems. First, the electricity that SMRs produce is far more expensive than diesel-based electricity. Second, even ignoring this problem, the total demand for electricity at these proposed markets is insufficient to justify investing in a factory to manufacture the SMRs.
SMRs have been proposed as a way to deal with many problems associated with large nuclear power plants, in particular the high costs of construction, running to tens of billions of dollars. SMR designs have much in common with large nuclear reactors, including, most basically, their reliance on nuclear fission reactions to produce electricity. But they also differ from large nuclear reactors in two ways. First, they have electricity outputs of less than 300 megawatts (MW) and sometimes as low as a few MW, considerably lower than the outputs of 700 to 1500 MW typical of large nuclear reactors. Second, SMR designs use modular means of manufacturing, so that they need only be assembled, rather than fully constructed, at the plant site. While large reactors that have been constructed in recent years have also adopted modular construction, SMR designers hope to rely more substantially on these techniques.
A standard metric used to evaluate the economics of different energy choices is called the levelized cost of energy (LCOE). We calculated that the LCOE for SMRs could be over ten times greater than the LCOE for diesel-based electricity. The cheapest options are hybrid generation systems, with wind or solar meeting a part of the electricity demand and diesel contributing the rest.
Why this high cost? The primary problem is that the small outputs from SMRs run counter to the logic of economies of scale. Larger reactors are more cost-efficient because they produce more electricity for each unit of material (such as concrete and steel) they use and for the number of operators they employ. SMR proponents argue that they can make up for this through the savings from mass manufacture at factories and the learning that comes with manufacturing many reactors. The problem is that building a factory requires a sizable market, sometimes referred to as an order book. Without a large number of orders, the investment needed to build the factory will not be justified.
We estimated the potential market for SMRs at remote mines and communities in Canada. We drew primarily upon two databases produced by Natural Resources Canada regarding mining areas and remote communities. As of 2018, there were 24 remote mining projects that could be candidates for SMR deployment within the next decade. Currently, these projects use diesel generators with a total installed capacity of 617 MW. For remote communities, we calculated a fossil fuel (primarily diesel) generation capacity of 506 MW. But many of these communities had demands that were too low for even the smallest-output SMR under review at the Canadian Nuclear Safety Commission.
Even if all these potential buyers want to adopt SMRs for electricity supply, without regard to the economic or noneconomic factors weighing against the construction of nuclear reactors, the combined demand would likely be much less than 1000 MW. The minimum demand required to justify the cost of producing SMRs would be three to seven times higher.
Furthermore, we concluded that the economics of SMRs don’t compete when compared with other alternatives. The cost of electricity from SMRs was found to be much higher than the cost of wind or solar, or even of the diesel supply currently used in the majority of these mines and communities.
Of course, our estimates for the LCOEs of different sources are dependent on various assumptions. We tried varying these assumptions within reasonable limits and found that the main result — that electricity from SMRs is far more expensive than the corresponding costs of generating electricity using diesel, wind, solar or some combination thereof — remains valid. All else being equal, the assumed capital cost of constructing a SMR would have to decline by over 95 percent to be competitive with a wind-diesel hybrid system. The limited experience with SMRs that are being built around the world suggests that construction costs will be higher, not lower, than advocates promise.
Meanwhile, renewables and storage technologies have seen substantial cost declines over the past decades. Recent estimates place wind, solar and hybrid systems at costs competitive with diesel power. Successful demonstrations suggest that renewable hybrid applications are becoming increasingly feasible for heavy industry, and the implementation of numerous numerous projects in northern communities suggests a high level of social acceptance. Many northern and, in particular, Indigenous communities have an interest in self-determined decision-making and maintaining a good relationship with the land. In June 2019, for example, the Anishinabek Chiefs-in-Assembly, representing 40 First Nations across Ontario, unanimously expressed opposition to SMRs. Grand Council Chief Glen Hare announced that the Anishinabek Nation is “vehemently opposed to any effort to situate SMRs within our territory.”
Instead of focusing on SMRs, policy-makers should bolster support for other renewable generation technologies as key mechanisms to reduce carbon emissions and align with community values.
A Closer Look at Two Operational Small Modular Reactor Designs
There are literally dozens of small modular reactor (SMR) and microreactor designs being developed by different companies around the world, and some of the work has been going on for decades. Yet, only two designs have actually been built and put into commercial operation. POWER takes a closer look at both of them.
Power, by Aaron Larson 1 May 24
Many nuclear power supporters have long thought small modular reactors (SMRs) would revolutionize the industry. Advocates expect SMRs to shorten construction schedules and bring costs down through modularization and factory construction. They often cite numerous other benefits that make SMRs seem like no-brainers, and yet, only two SMR designs have ever been built and placed in commercial operation.
The International Atomic Energy Agency (IAEA) publishes booklets biennially on the status of SMR technology. In the IAEA’s most recent booklet, it notes 25 land-based water-cooled SMRs and another eight marine-based water-cooled designs are under development globally. It also lists 17 high-temperature gas-cooled SMRs, eight liquid-metal-cooled fast-neutron-spectrum SMRs, 13 molten-salt SMRs, and 12 microreactors. If you do the math, that’s 83 SMR designs under development, but only the KLT-40S and HTR-PM are actually operational.
KLT-40S
The KLT-40S is a pressurized water reactor (PWR) that was developed in Russia. It is an advanced version of the KLT-40 reactor, which has been used in nuclear-powered icebreakers. The first KLT-40S units, and, to date, the only two of these units to enter commercial operation, were deployed in the Akademik Lomonosov—the world’s first purpose-built floating nuclear power plant (FNPP, Figure 1 on original).
Main Design Features.………………………………………………………………………………………………………….
Deployment Details.…………………………….
Construction and testing of the FPU was completed in 2017 at the Baltic shipyard. In May 2018, the vessel was towed 4,000 kilometers (km), around Finland and Sweden, to Murmansk, completing the first leg of its journey to Pevek. Fuel loading was completed in Murmansk in October 2018. First criticality was achieved in November 2018, then in August 2019, the vessel embarked on the second leg of its journey—a distance of 4,700 km—towed by two tugboats to the Arctic port town of Pevek, where it was connected to the grid on Dec. 19, 2019. Akademik Lomonosov was fully commissioned on May 22, 2020, and it currently provides heat to the town of Pevek and supplies electricity to the regional Chaun-Bilibino power system.
HTR-PM
On Dec. 6, 2023, China National Nuclear Corp. announced it had commenced commercial operation of the high-temperature gas-cooled modular pebble bed (HTR-PM) reactor demonstrator. The HTR-PM project was constructed at a site in Rongcheng, Shandong Province, roughly midway between Beijing and Shanghai in eastern China…………………………………
Main Design Features.…………………………………………………………………………………………………..
Deployment Details.……………………………………………………………………. The civil work for the nuclear island buildings was completed in 2016 with the first of two reactor pressure vessels installed in March that year. The fuel plant reached its expected production capacity in 2017. Startup commissioning and testing of the primary circuit were finished by the end of 2020. The HTR-PM achieved first criticality in September 2021, and was ultimately grid connected on Dec. 20, 2021.
Spotty Results at Best
While it is laudable that these SMRs—the KLT-40S and HTR-PM—have been placed in commercial operation, their performance since entering service has come under fire. In The World Nuclear Industry Status Report 2023 (WNISR), a Mycle Schneider Consulting Project, co-funded by the German Federal Ministry for the Environment, Nature Conservation, Nuclear Safety, and Consumer Protection, it says both designs have operated at low capacity factors recently.
Concerning the Chinese HTR-PM, the WNISR says, “Between January and December 2022, the reactors operated for only 27 hours out of a possible maximum of 8,760 hours. In the subsequent three months, they seem to have operated at a load factor of around 10 percent.” The Russian units’ performance has been nearly as dismal. “The operating records of the two KLT-40S reactors have been quite poor. According to the IAEA’s PRIS [Power Reactor Information System] database, the two reactors had load factors of just 26.4 and 30.5 percent respectively in 2022, and lifetime load factors of just 34 and 22.4 percent. The reasons for the mediocre power-generation performance remain unclear,” the report says.
Meanwhile, the promises of shortened timelines and lower costs were not borne out by these projects. “The experience so far in constructing these two SMRs as well as estimates for reactor designs like NuScale’s SMR show that these designs are also subject to the historical pattern of cost escalations and time overruns. Those cost escalations do make it even less likely that SMRs will become commercialized, as the collapse of the Carbon Free Power Project involving NuScale reactors in the United States illustrated,” the WNISR says………….. https://www.powermag.com/a-closer-look-at-two-operational-small-modular-reactor-designs/
ARC might need to redesign its SMR technology: former president + US bans import of enriched uranium + more to the story
Susan O’Donnell, 2 May 24 To clarify, there’s currently no enrichment plant in the US that produces HALEU (fuel enriched between 5 and 20 percent), as far as I’m aware. Any nuclear fuel enrichment happening in the U.S. would be for the existing light-water reactors that use fuel enriched to less than 5 percent. My take: the idea that the ARC reactor design could change from using HALEU fuel to low enriched uranium is frankly ridiculous. It would not be the same reactor at all, it would be a completely different design. Quote: “It’s not something that can’t be fixed,” Sawyer said. Fixed? WTF? This whole project is a scam. |
U.S. Senate passes Russian uranium import ban

The article above is about the shortage of HALEU, the fuel currently only available in Russia that is needed by the designs of advanced reactors cooled by liquids other than water. The design for the ARC reactor slated for Point Lepreau in New Brunswick requires HALEU.

ARC might need to redesign its SMR technology: former president
Norm Sawyer points to other companies around the world that pivoted quickly to address the lack of enriched uranium available
Adam Huras
Published May 01, 2024
The former president and CEO of ARC Clean Technology says the company might need to redesign its small modular nuclear reactor technology.
Norm Sawyer points to other companies around the world that pivoted quickly to address the lack of enriched uranium available.
Brunswick News reported earlier this week that ARC is still in search of a new enriched uranium supplier, after it originally planned to buy from Russia.
Meanwhile, Energy Minister Mike Holland says he has been assured that “there’s a queue for North American enriched uranium and we’re in it,” maintaining the company that the Higgs government spent $20 million on won’t be shut out.
Firms around the world developing a new generation of small nuclear reactors to help cut carbon emissions have been forced to face a big problem: The only company that sells the enriched fuel they need is Russian.
“It’s not only ARC, the industry in general is really dealing with the fallout of the war,” Sawyer said, who is now a nuclear consultant through his own firm. “Russia is the main supplier of HALEU around the world.”
High-assay low-enriched uranium (HALEU) is an integral component of the company’s ARC-100 sodium-cooled fast reactor, as well as a number of other advanced reactors currently in development attempting to achieve smaller designs.
But it’s not as simple as finding that enriched uranium closer to home.
While Canada mines uranium – there are currently five uranium mines and mills operating in Canada, all located in northern Saskatchewan – it does not have uranium enrichment plants.
The U.S. opened its first and only enrichment plant last year, operated by Centrus Energy in Ohio, amid a federal push to find a solution to the Russia problem.
It remains the only facility in the U.S. licensed to enrich uranium.
It currently has contracts with two American companies pursuing SMR technology, although it says it could rapidly expand production with federal investment.
One of those, TerraPower, a nuclear reactor developer founded by Bill Gates, has said Russia’s invasion would mean a delay to the deployment of its Natrium reactor by at least two years.
Other companies have pivoted.
Sawyer pointed to Denmark’s Seaborg Technologies that announced last year it would be changing its proposed SMR fuel from HALEU to low-enriched uranium “due to the risks associated with developing a sufficient supply.”
That resulted in design changes.
It was a move the company said was necessary to meet its planned timeline to see a first group of SMRs ready by 2028……………………………………………………..
What I’ve been told that there are a number of things taking place to ensure that there’s a queue for North American enriched uranium and we’re in it,” Holland said.
“That’s what I’ve been told and told definitively.”
Holland said the U.S. has a “vested interest” in aiding Canada and its SMR technology because Canada has the uranium they’re going to need as well.
“There are people saying ‘hey, if Canada is going to be your large supplier we’re going to have to work out, quid pro quo, that we don’t get excluded,’” he said.
Holland maintained that “our toe is stuck in the door so we have an opportunity to be part of that supply chain………………………………..
Sawyer said making a change to a different fuel means components will need to be redesigned.
“Obviously, you design a reactor for the type of fuel you’re going to use so there’s obviously some work to be done to realign the reactor core to the new type of fuel,” he said. “Is it easy? I’m not sure if it’s easy. There is some work to be done, there’s no doubt.”
Sawyer added that there’s two components to SMRs: the reactor design, construction and deployment, and then the fuel.
“Any delay on either one of those sides of the equation could cause a delay later on,” he said.
Five Things the “Nuclear Bros” Don’t Want You to Know About Small Modular Reactors
1. SMRs are not more economical than large reactors.
2. SMRs are not generally safer or more secure than large light-water reactors.
3. SMRs will not reduce the problem of what to do with radioactive waste.
4. SMRs cannot be counted on to provide reliable and resilient off-the-grid power for facilities, such as data centers, bitcoin mining, hydrogen or petrochemical production.
5. SMRs do not use fuel more efficiently than large reactors.

Even casual followers of energy and climate issues have probably heard about the alleged wonders of small modular nuclear reactors (SMRs). This is due in no small part to the “nuclear bros”: an active and seemingly tireless group of nuclear power advocates who dominate social media discussions on energy by promoting SMRs and other “advanced” nuclear technologies as the only real solution for the climate crisis. But as I showed in my 2013 and 2021 reports, the hype surrounding SMRs is way overblown, and my conclusions remain valid today.
Unfortunately, much of this SMR happy talk is rooted in misinformation, which always brings me back to the same question: If the nuclear bros have such a great SMR story to tell, why do they have to exaggerate so much?
What are SMRs?
SMRs are nuclear reactors that are “small” (defined as 300 megawatts of electrical power or less), can be largely assembled in a centralized facility, and would be installed in a modular fashion at power generation sites. Some proposed SMRs are so tiny (20 megawatts or less) that they are called “micro” reactors. SMRs are distinct from today’s conventional nuclear plants, which are typically around 1,000 megawatts and were largely custom-built. Some SMR designs, such as NuScale, are modified versions of operating water-cooled reactors, while others are radically different designs that use coolants other than water, such as liquid sodium, helium gas, or even molten salts.
To date, however, theoretical interest in SMRs has not translated into many actual reactor orders. The only SMR currently under construction is in China. And in the United States, only one company—TerraPower, founded by Microsoft’s Bill Gates—has applied to the Nuclear Regulatory Commission (NRC) for a permit to build a power reactor (but at 345 megawatts, it technically isn’t even an SMR).
The nuclear industry has pinned its hopes on SMRs primarily because some recent large reactor projects, including Vogtle units 3 and 4 in the state of Georgia, have taken far longer to build and cost far more than originally projected. The failure of these projects to come in on time and under budget undermines arguments that modern nuclear power plants can overcome the problems that have plagued the nuclear industry in the past.
Developers in the industry and the US Department of Energy say that SMRs can be less costly and quicker to build than large reactors and that their modular nature makes it easier to balance power supply and demand. They also argue that reactors in a variety of sizes would be useful for a range of applications beyond grid-scale electrical power, including providing process heat to industrial plants and power to data centers, cryptocurrency mining operations, petrochemical production, and even electrical vehicle charging stations.
Here are five facts about SMRs that the nuclear industry and the “nuclear bros” who push its message don’t want you, the public, to know.

by Jov Onsat, Rigzone Staff, Thursday, May 02, 2024
The French government has received clearance from the European Commission to provide Electricité de France (EDF) a further EUR 300 million ($321.6 million) for the front-end design phase of a project to develop small modular nuclear reactors (SMRs).
The project by Nuward, the nuclear energy-focused subsidiary of state-owned EDF, aims to come up with a design that has a power output of up to 300 megawatts electric.
The front-end design is the third phase of the five-phase project. The Commission previously approved EUR 50 million ($53.6 million) in French state aid for the second phase, which focused on gathering new knowledge for SMR design and construction.
Under the measure, the aid will take the form of a direct grant of up to EUR 300 million that will cover the R&D [research and development] project until early 2027”, the Commission said in a statement announcing clearance for the new funding from European Union competition regulations. “The measure will support Nuward in sizing the modules and components of the SMRs and validating their integration in the SMRs by means of numerical simulators and laboratory tests.
“Nuward will also carry out industrialization studies relating to the modular design and mass production of SMRs. Finally, the measure will also support Nuward in the preparation of the required safety demonstrations for the approval of the project by the national nuclear safety authorities”.
The Commission recently launched an alliance to accelerate the development of SMRs, following moves by the United Kingdom and United States to commercially scale up the advanced nuclear generation technology.
The public-private coalition aims to come up with a working model by the 2030s. “The Alliance targets a wide range of SMR stakeholders including vendors, utilities, specialized nuclear companies, financial institutions, research organizations, training centers and civil society organizations”, the Commission said in a press release February 9 announcing the initiative…………………..
Earlier the UK government announced an investment of GBP 300 million ($376 million) for the domestic production of high-assay low-enriched uranium (HALEU), challenging Russia’s status as the only commercial manufacturer of the fuel for SMRs. The UK previously funded a program by Rolls-Royce PLCs to design an SMR model, which is currently awaiting approval for deployment in Poland, as announced by the company last week—though the product is still undergoing the regulatory design assessment in the UK.
The UK will become the first country in Europe to launch a high-tech HALEU nuclear fuel program, strengthening supply for new nuclear projects and driving Putin further out of global energy markets”, the UK Department of Energy Security and Net Zero (DESNZ) said in a news release January 7 announcing the HALEU funding.
The DESNZ said GBP 10 million ($12.5 million) has also been allotted to develop sites and promote skills development for the production of other “advanced nuclear fuels”.
The International Atomic Energy Agency says HALEU is only produced in the U.S. and Russia but only the latter makes the fuel at a commercial scale. SMRs need HALEU, which contains five to 20 percent of uranium-235, beyond the five percent level that fuels most of today’s nuclear power plants, according to the United Nations nuclear watchdog.
The UK move was followed by an announcement by the US Department of Energy (DOE) offering contracts worth up to $500 million in total for HALEU production, besides funding offers for SMR design development. “Currently, HALEU is not commercially available from U.S.-based suppliers, and boosting domestic supply could spur the development and deployment of advanced reactors in the United States”, the DOE noted in a media statement January 9 announcing the funding offer.
Last year the U.S. Nuclear Regulator Commission issued the country’s first certification for an SMR design, that of NuScale Power Corp. https://www.rigzone.com/news/france_increases_state_funding_for_advanced_nuclear_rd_project-02-may-2024-176607-article/
Rolls-Royce scales back plans to build nuclear factories in UK
Rolls-Royce has scaled back plans to build two new factories for its small modular reactor (SMR) programme in the UK, following delays to a government design competition.
The FTSE 100 company had originally proposed one factory to make heavy pressure vessels for its SMRs and another to make the building blocks of the reactors.
It had drawn up a final shortlist of locations for the pressure vessels factory, including the International Advanced Manufacturing Park on the outskirts of Sunderland, Teesworks in Redcar and the Gateway industrial park in Deeside, Wales.
But on Friday Rolls confirmed it no longer intends to proceed with that plan because there is no longer time to build the factory and make the first pressure vessels for the early 2030s, when it hopes to complete its first SMRs.
It is still proceeding with work to build the second factory, however.
The company had been waiting for the outcome of an ongoing SMR design competition in the UK – first announced by the Government in 2015 – before it made a decision on the pressure vessel plant.
But that competition has been repeatedly delayed, with the arms length body Great British Nuclear only formally created last summer and winners not due to be announced until this June at the earliest.
Instead the engineering giant will now buy its heavy pressure vessels from a third party supplier.
The large, metal components sit at the heart of nuclear reactors and must be able to withstand extremely high temperatures and pressures. They are only made by a select group of companies, partly due to the need for specialist welding techniques.
Among their number is now Sheffield Forgemasters, which was nationalised by the Ministry of Defence in 2021.
Earlier this month, Sheffield became the sole UK company to gain the qualifications needed to make SMR reactor vessel components.
Despite having shelved its plans for a heavy pressure vessel factory, Rolls is still pressing ahead with plans to build its second factory, which will build the modular units that make up its SMRs.
It is understood that sites shortlisted for the pressure vessel factory will also be contenders for the second plant but no decisions have been made.
On Friday, a spokesman for Rolls-Royce SMR confirmed the company had now “prioritised work on our modules assembly and test facility”, adding: “Our efforts are focused on identifying the best site to support our deployment at pace.”
The company has also not ruled out reviving its plan for a heavy pressure vessel factory at some point in the future, so long as it manages to build up a healthy pipeline of orders.
A Government spokesman said: “Our world leading SMR competition aims to be the fastest of its kind, helping secure billions in investment for the UK, meaning cleaner, cheaper and more secure energy in the long-term.”
