The claim that nuclear power is needed for national security is a masked money-grab

 that price won’t only be paid by emptying our wallets . It will also be paid in health and safety. State senators with dollar signs twinkling in their eyes are lining up for relief handouts that will do nothing to fix our healthcare crises — laid bare under the coronavirus crisis — nor our economy. But they are playing the Russia card to get the money.

The claim that nuclear power is needed for national security is a masked money-grab

The US Department of Energy’s assertions about Russian and Chinese supremacy in the nuclear sector is reminiscent of the “Commie plot” rhetoric of the 1950s. But it’s a thinly disguised ploy to feed at the federal subsidies trough and revive a moribund industry.

A few years ago I attended two days of the Nuclear Deterrence Summit, held just outside Washington, DC. In my defense, I’ll say it was a necessity. I really wanted to get inside how these people think. There was plenty of talk about the need for nuclear weapons, their range and potency, all done with a calm equilibrium devoid of conscience. It was chilling.

But it was also the theatre of the absurd. At one point there was actually talk about a “missile gap.” The Russians were getting ahead. This must be stopped. Was I on the set of a remake of Dr. Strangelove? Was this General ‘Buck’ Turgidson railing about “commie plots” and “mineshaft gaps”?

Life, as it turns out, is routinely stranger than any fiction. Turgidson is still with us, and he has extended his brief to include “civilian” nuclear power plants in the competition with the “Ruskies” and now, the Chinese. Continue reading

NuScam’s “small nuclear reactor” project runs into yet more trouble

Nuclear Intelligence Weekly 15th May 2020, The US Nuclear Regulatory Commission (NRC) said that NuScale has not “sufficiently validated” the design and performance of the steam generator in its 50 megawatt small modular reactor (SMR) currently under design certification review. The NRC is nevertheless still expected to certify the SMR design but without granting “finality” to the steam generator, touted by the Fluor subsidiary as one of the key innovations to its smaller”cost-competitive” design.
That will likely inhibit the company’s ability to attract further investment to the project, which Fluor itself is no longer investing in.  NuScale submitted its design certification applicationto the NRC in December 2016 and the NRC is expected to grant the certification later this year or early next year.
That, however, depends on the outcome of a staff review of unrelated changes to the SMR’s emergency
core cooling system that NuScale plans to submit to the NRC on May 20.  Instead of resolving the steam generator design issue ahead of design certification, the NRC is deferring to the plant operator Energy Northwest
to resolve the issue during the licensing process, after construction.http://www.energyintel.com/pages/eig_article.aspx?DocId=1072564

Australian politician John Barilaro gets it so wrong about small nuclear reactors

Electrical Review 4 May 2020  I have to conclude that the Deputy Premier of New South Wales, John Barilaro, is a remarkable clairvoyant. He has announced unequivocally on Australian media that Rolls Royce is set to build up to 15 new small-size nuclear reactors in Britain over the next nine years.
Strange this. Just 18 months ago, according to the Financial Times, Rolls-Royce was preparing to shut down altogether its R&D project to develop small modular nuclear reactors, unless the British government agreed to an outrageous set of demands and subsidies. Granted the Johnson government has bunged them a few million to keep the R&D going.

But there is as yet no sign of anything being oven-ready to come to the marketplace, let alone 15 up and running. But there remain some rather disturbing connections between small reactor projects and nuclear weapons proliferation. And Rolls-Royce does offer up one of the most glaring examples. Part of the company’s current sales pitch to the British government includes the argument that a civil small-reactor industry in the UK “would relieve the Ministry of Defence of the burden of developing and retaining skills and capability” for its weapons programme. It may be true. But it is not really Atoms for Peace, , is it?

U.S. taxpayers might cough up for a private company’s new “Small Nuclear” space travel gimmick

Private companies find role in developing nuclear power for space travel, Space.com By JoAnna Wendel – Space.com contributor 6 Apr 20, 

Nuclear-powered spacecraft could cut our travel time to Mars in half. Space is abouto go nuclear — at least if private companies get their way.

At the 2 t3rd annual Commercial Space Transportation Conference (CST) in Washington, D.C., in January, a panel of nuclear technology experts and leaders in the commercial space industry spoke about developments of the technology that could propel future spacecraft faster and more efficiently than current systems can.

Nuclear technology has powered spacecraft such as NASA’s Mars rovers, the Cassini mission and the two Voyagers that are currently exploring the outer reaches of our solar system. But those fuel sources rely on the passive decay of radioactive plutonium, converting heat from that process into electricity to power the spacecraft.

Instead, the CST panelists discussed Nuclear Thermal Propulsion (NTP), a technology developed in the 1960s and ’70s that relies on the splitting, or fission, of hydrogen atoms. Although fission is associated with more warlike images, the panel’s experts emphasized the safety of nuclear thermal propulsion, which would use low-enriched uranium.

An NTP-powered spacecraft would pump hydrogen propellant through a miniature nuclear reactor core. Inside this reactor core, high energy neutrons would split uranium atoms in fission reactions; those freed neutrons would smack into other atoms and trigger more fission. The heat from these reactions would convert the hydrogen propellent into gas, which would produce thrust when forced through a nozzle.

This chain reaction is the key to NTP’s power, panelist Venessa Clark, CEO of Atomos Space, a company that’s developing thermonuclear propulsion powered spacecraft to provide in-space transportation options to satellite operators, told Space.com. A soda-can-size fission reactor could propel humans to Mars in just three to four months, she said, about twice as fast as the currently estimated time it could take a chemically propelled ship to carry humans to the Red Planet. …..

But the government still has to play some role, both Clark and Thornburg said. Government agencies like NASA and the military branches may be the first clients for these commercial companies. Clark noted NASA’s recent pushes to partner with the private sector, such as its commercial lunar payload services program and its commercial crew program.

“Government players, NASA and also now the Air Force are looking at procuring services rather than funding the development of technology, which is really exciting for us,” Clark said…. https://www.space.com/commercial-nuclear-power-for-faster-space-travel.

Quote from article”Instead, the CST panelists discussed Nuclear Thermal Propulsion (NTP), a technology developed in the 1960s and ’70s that relies on the splitting, or fission, of hydrogen atoms” Whoever wrote that needs to learn some basic nuclear physics. In nuclear thermal propulsion the atoms of a fissile heavy element (such as Uranium 235 in the designs mentioned) are split, hydrogen is the simplest and lightest of the elements and cannot be split (hydrogen atoms can however be joined together in the process of nuclear fusion, but that is a different process). Where hydrogen comes in is that in the NTP designs it is the propellant gas that is heated by the nuclear fission reactor to provide propulsion, hydrogen is chosen because being the lightest element it achieves the highest exhaust velocities.

British small nuclear reactors to help Turkey to get nuclear weapons?

Fears over nuclear Turkey after Rolls Royce reactor deal, Morning Star, 

 MARCH 25, 2020   ENGINEERING firm Rolls-Royce has struck a deal with Turkey for the production of nuclear mini-reactors, sparking fears that the British company and its international consortium partners are helping pave the way for Ankara to develop a nuclear bomb…..

It is part of a consortium including BAM Nuttall, Laing O’Rourke, National Nuclear Laboratory, Atkins and others. They will work together on designing the new power plant. ….

the plans have raised fears that Turkey’s authoritarian President Recep Tayyip Erdogan could use the development as a step towards the country becoming a nuclear-armed power.

As previously reported in the Morning Star, Turkey’s secret nuclear programme includes plans to acquire weapons of mass destruction (WMDs), including nuclear missiles.

The plans have been given the green light by Mr Erdogan’s religious adviser Hayreddin Karaman, who provided not only his blessing for the government to acquire WMDs but also encouraged its leadership to do so.

Writing in a pro-government newspaper in 2017, Mr Karaman said: “We need to consider producing these weapons, rather than purchasing them, without losing any time and with no regard to words of hindrance from the West.”

There are already some 70 US-owned nuclear warheads said to be based at Incirlik airbase near the southern of Adana.

About 40 of these are thought to be under Turkish control, though details are patchy due to a lack of openness and transparency.

In previous deals with Russia and a Japanese-French consortium, the door was left open for the development of nuclear weapons after Turkey rejected offers to include the provision of uranium and the return of the spent fuel rods used in the reactors.

Ankara would be able to use its own low-enriched uranium and reprocess the fuel rods, producing its own enriched uranium for the development of nuclear weapons.

The development has parallels with the Indian missile capability developed after the testing of plutonium produced in the Canadian-supplied Cirus reactor, which first raised the issue that nuclear technology supplied for peaceful purposes could be diverted to weapons production. https://morningstaronline.co.uk/article/b/fears-over-nuclear-turkey-after-rolls-royce-reactor-deal

How will the IAEA spin the mind-boggling costs of Small Modular Nuclear Reactors (SMRs)?

IAEA launches project to examine economics of SMRs   https://www.world-nuclear-news.org/Articles/IAEA-launches-project-to-examine-economics-of-SMRs  26 March 2020,  he International Atomic Energy Agency (IAEA) is launching a three-year Coordinated Research Project focused on the economics of small modular reactors (SMRs). The project will provide Member States with an economic appraisal framework for the development and deployment of such reactors.
The IAEA said it had launched the project in response to increased interest in SMRs, noting that multiple SMR projects are currently under development (involving about 50 designs and concepts) and at varying technology readiness levels. Their costs and delivery times need to be adequately estimated, analysed and optimised, it said. Specific business models have to be developed to address the market’s needs and expectations. The market itself should be large enough to sustain demand for components and industrial support services. However, the economic impact of SMR development and deployment must be quantified and communicated to gain societal support, it said.

Participants in the research project will cover: market research; analysis of the competitive landscape (SMR vs non-nuclear alternatives); value proposition and strategic positioning; project planning cost forecasting and analysis; project structuring, risk allocation and financial valuation; business planning and business case demonstration; and economic cost-benefit analysis.

The framework they establish will be applied, in particular, to assess the economics of multiples (serial production of reactors in a factory setting), factory fabrication (conditions to be met for a factory to exist), and supply chain localisation (opportunities and impacts).

The deadline for proposals to participate in the research project is 30 April.

In early 2018, the IAEA announced it was forming a Technical Working Group to guide its activities on SMRs and provide a forum for Member States to share information and knowledge. The group, comprising some 20 IAEA Member States and international organisations, held its first meeting in April that year.

Military use: that is clearly the reason for developing Small Nuclear Reactors

If the testing goes well, a commercially developed, Nuclear Regulatory Commission licensed reactor will be demonstrated on a “permanent domestic military installation.
Pentagon awards contracts to design mobile nuclear reactor Defense News 
By: Aaron Mehta    March 9  WASHINGTON— The Pentagon on Monday issued three contracts to start design work on mobile, small nuclear reactors, as part of a two-step plan towards achieving nuclear power for American forces at home and abroad.

The department awarded contracts to BWX Technologies, Inc. of Virginia, for $13.5 million; Westinghouse Government Services of Washington, D.C. for $11.9 million; and X-energy, LLC of Maryland, for $14.3 million, to begin a two-year engineering design competition for a small nuclear microreactor designed to potentially be forward deployed with forces outside the continental United States.

The combined $39.7 million in contracts are from “Project Pele,” a project run through the Strategic Capabilities Office (SCO), located within the department’s research and engineering side. The prototype is looking at a 1-5 megawatt (MWe) power range. The Department of Energy has been supporting the project at its Idaho National Laboratory.

Pele “involves the development of a safe, mobile and advanced nuclear microreactor to support a variety of Department of Defense missions such as generating power for remote operating bases,” said Lt. Col. Robert Carver, a department spokesman. “After a two-year design-maturation period, one of the companies funded to begin design work may be selected to build and demonstrate a prototype.”…….

A second effort is being run through the office of the undersecretary of acquisition and sustainment. That effort, ordered in the 2019 National Defense Authorization Act, involves a pilot program aiming to demonstrate the efficacy of a small nuclear reactor, in the 2-10 MWe range, with initial testing at a Department of Energy site in roughly the 2023 timeframe.

If the testing goes well, a commercially developed, Nuclear Regulatory Commission licensed reactor will be demonstrated on a “permanent domestic military installation by 2027,” according to DoD spokesman Lt. Col. Mike Andrews. “If the full demonstration proves to be a cost effective energy resilience alternative, NRC-licensed [reactors] will provide an additional option for generating power provided to DoD through power purchase agreements.”…….

According to Dr. Jonathan Cobb, a spokesman for the World Nuclear Association, small nuclear reactors come in three flavors. The first, small modular reactors, sit in the 20-300 MWe range and are approaching the point they will appear on market.

The second category sits from 10-100 megawatts, and have been used in transports such as icebreakers. According to Cobb, a pair of 32 MWe reactors, based on icebreaker technology, are being used aboard the Akademik Lomonosov, a Russian “floating power plant.”

The third category, covering what the Pentagon appears most interested in, is a category known as microreactors. The challenge, Cobb said, is that this group is the furthest behind technologically, with demonstrations of commercial systems targeted for “the second half of the 2020s,” putting them in the “ballpark” of what DoD is looking for with its A&S effort……

Edwin Lyman, director of the Nuclear Safety Project at the Union of Concerned Scientists, has concerns about the availability of fuel to power a proliferation of small nuclear reactors. He noted, “there are no clear plans for manufacturing the quantity of high-assay low enriched uranium, much less the production of high-quality TRISO [TRi-structural ISOtropic particle] fuel, that would be able to meet timelines this decade.”……

Lord, for her part, would not rule out working with foreign allies on the nuclear program in some way, saying “We always talk with our partners and allies about collaboration. We have many umbrella vehicles, if you will, to do that, particularly with [National Technology and Industrial Base] countries — U.K., Canada, Australia. We have a little bit of an easy button there for working back and forth with technical information.”…    https://www.defensenews.com/smr/nuclear-arsenal/2020/03/09/pentagon-to-award-mobile-nuclear-reactor-contracts-this-week/?fbclid=IwAR2MTkRUDqIkruQHY0RivblBzoSY6gubpl8gkWDUDhedVwZEGstJhHYLb6U#.XmawxEl-aJ0.facebook

A ruse to save the nuclear industry? Dangerous, expensive portable mini-reactors

March 16, 2020 Posted by | Small Modular Nuclear Reactors, USA | Leave a comment

Proponents of Small Nuclear Reactors need a reality check – about the STAGGERING COST

a reality check is in order. A handful of small reactors is under construction but they have been subject to huge cost overruns and delays. William Von Hoene, senior vice-president of Exelon ‒ the largest operator of nuclear power plants in the US ‒ says that no more large reactors will be built in the US and that the cost of small reactors is “prohibitive”.

Rolls-Royce sharply reduced its small-reactor investment to “a handful of salaries” in 2018 and is threatening to abandon its R&D altogether unless the British government agrees to an outrageous set of demands and subsidies.

And they say that small nuclear reactors do not have military applications

Pentagon awards contracts to design mobile nuclear reactor Defense News

The best way to differentiate between the programs may be to think of the A&S effort as the domestic program, built off commercial technology, as part of an effort to get off of local power grids that are seen as weak targets, either via physical or cyber espionage. Pele is focused on the prototyping a new design, with forward operations in mind — and may never actually produce a reactor, if the prototype work proves too difficult…… https://www.defensenews.com/smr/nuclear-arsenal/2020/03/09/pentagon-to-award-mobile-nuclear-reactor-contracts-this-week/

A sceptical look at NuScam’s small nuclear reactor plans

Recent experience supports skepticism. Westinghouse worked on an SMR design for a decade before giving up in 2014. Massachusetts-based Transatomic Power, a nuclear technology firm, walked away from a molten salt SMR in 2018, and despite an $111 million dollar infusion from the US government, a SMR design from Babcock & Wilcox, an advanced energy developer, folded in 2017. While the Russians have managed to get their state-funded SMR floating, its construction costs ran over estimates by four times, and its energy will cost about four times more than current US nuclear costs. 
Eventually, every nuclear conversation turns to radioactive waste and safety. SMRs using a pressurized water reactor will continue to generate highly radioactive spent fuel, yet no country has a permanent solution for how to safely store this kind of waste.  ……..
small modular reactors suffer from many of the same problems as large reactors, most notably safety issues
“It would be irresponsible for the NRC to reduce safety and security requirements for any reactor of any size.”

The Smaller Is Better Movement in Nuclear Power, Are miniature reactors really safer? Mother Jones  LOIS PARSHLEY, 8 Mar 20, 

Huge computer screens line a dark, windowless control room in Corvallis, Oregon, where engineers at the company NuScale Power hope to define the next wave of nuclear energy. Glowing icons fill the screens, representing the power output of 12 miniature nuclear reactors. Together, these small modular reactors would generate about the same amount of power as one of the conventional nuclear plants that currently dot the United States—producing enough electricity to power 540,000 homes. On the glowing screens, a palm tree indicates which of the dozen units is on “island mode,” allowing a single reactor to run disconnected from the grid in case of an emergency. 

This control room is just a mock-up, and the reactors depicted on the computer screens do not, in fact, exist. Yet NuScale has invested more than $900 million in the development of small modular reactor (SMR) technology, which the company says represents the next generation of nuclear power plants. NuScale is working on a full-scale prototype and says it is on track to break ground on its first nuclear power plant—a 720-megawatt project for a utility in Idaho—within two years; the US Nuclear Regulatory Commission has just completed the fourth phase of review of NuScale’s design, the first SMR certification the commission has reviewed. The company expect final approval by the end of 2020. The US Department of Energy has already invested $317 million in the research and development of NuScale’s SMR project.

Small nuclear reactors to fix climate change? IT’S A LIE ! – theme for March 2020

They depend on  long carbon -emitting chains of mining, transport, construction, and then demolition,  disposal of long lasting toxic radioactive trash.

Even if Small Nuclear Reactors did work against climate change (which they don’t) –  any such effect would require millions of them to be set up immediately.  Go figure.

Author information:

Lindsay Krall is a post-doctoral Macarthur fellow at the George Washington University Institute for International Science and Technology Policy. Her research focuses on policies for the back end of the nuclear fuel cycle, particularly as they pertain to radionuclide transport in the environment, systems and organizations for waste storage and disposal, and the long-term behavior of spent fuels from advanced reactors. Allison Macfarlane is Professor of Public Policy and International Affairs at the George Washington University’s Elliott School of International Affairs. She directs the school’s Institute for International Science and Technology Policy Program and is the former chairman of the US Nuclear Regulatory Commission. Macfarlane was a member of the Blue Ribbon Commission on America’s Nuclear Future from 2010-2012.

“Abstract:

Nuclear energy-producing nations are almost universally experiencing delays in the commissioning of the geologic repositories needed for the long-term isolation of spent fuel and other high-level wastes from the human environment. Despite these problems, expert panels have repeatedly determined that geologic disposal is necessary, regardless of whether advanced reactors to support a “closed” nuclear fuel cycle become available. Still, advanced reactor developers are receiving substantial funding on the pretense that extraordinary waste management benefits can be reaped through adoption of these technologies. Here, the authors describe why molten salt reactors and sodium-cooled fast reactors – due to the unusual chemical compositions of their fuels – will actually exacerbate spent fuel storage and disposal issues. Before these reactors are licensed, policymakers must determine the implications of metal- and salt-based fuels vis a vis the Nuclear Waste Policy Act and the Continued Storage Rule.” end quote.Emphasis added for clarity. Mr. O’Brien and Mr. Bernardi need to consider the scientific and technical reality behind the gloss they want to disseminate.

NuScale’s nuclear reactor looks suspiciously like an old design, (that melted down)

Why Does NuScale SMR Look Like a 1964 Drawing of Swiss Lucens Nuclear Reactor (which suffered a major meltdown in 1969)?
https://miningawareness.wordpress.com/2015/08/31/why-does-nuscale-smr-look-like-a-1964-drawing-of-swiss-lucens-nuclear-reactor-which-suffered-a-major-meltdown-in-1969/
Whatever NuScale is, or is not, it clearly isn’t “new”. The Bible must have foreseen the nuclear industry when it said that there was no new thing under the sun. While there might be something new about it, certainly its scale is not. And, it seems mostly a remake of old military reactors, perhaps with influence from swimming pool reactors.

The main ancestor seems to be the US Army’s SM-1, made by the American Locomotive Company, making its most distant ancestor the steam locomotive.

Government subsidizes for NuScale are a deadly taxpayer rip rip-off. Even without an accident, nuclear reactors legally leak deadly radionuclides into the environment during the entire nuclear fuel chain, as well as when they are operating. Then, the nuclear waste is also allowed to leak for perpetuity.

The 1964 Lucens Design certainly looks like the one unit NuScale. Did MSLWR, now NuScale, take from Lucens or from an earlier common design ancestor?

NuScale 12 years ago when it was called MASLWR and still an official government project, 2003, INEEL/EXT-04-01626.

This is for single reactors. They want to clump them together.

Is there a common ancestor in either the US nuclear power station in Greenland or Antarctica? Actually, the main “parent” for the underground concept, according to the Swiss documentation, is underground hydroelectric power stations, dating from the 1800s. These caverns have been known to collapse, which, along with the WIPP collapse, points to another risk associated with underground nuclear reactors, besides leakage and corrosion.
being mostly in an underground cavern proved to be a liability rather than an asset for Lucens. The cavern leaked water and contributed to corrosion issues that ultimately led to nuclear meltdown.

Despite its tiny size, tinier than NuScale, it still is classified as a major nuclear accident. Furthermore, the cavern did not keep the nuclear fallout from escaping into the environment. There was 1 Sv (1000 mSv) per hour of
radiation in the cavern. Radiation was measured in the nearby village, and the cavern still leaks radiation. Continue reading
