USA Department of Energy enthuses about Highly Enriched Uranium in space. Not everyone agrees
As I’ve mentioned before on this site, the oh so confident macho nuclear enthusiasts don’t need to do precautions, even though USA is in the thick of the pandemic. Only the 2 token women have the brains to wear masks.
US Ramps Up Planning for Space Nuclear Technology AIP, 31 July 20, NASA and the Department of Energy are expanding their collaboration as part of a broader White House push to develop nuclear power systems for space applications. The initiative comes as NASA faces key decisions on what fuel sources and technology development paths to pursue.
Now, NASA, DOE, and the White House want nuclear power to play a much larger role in space exploration as plans take shape for a sustained human presence on the Moon and subsequent crewed journeys to Mars……….
The American Nuclear Society hosted a debate on the topic at its annual meeting in June. While the society has generally supported the use of space nuclear power and propulsion in the past, it has decided to develop a position statement by spring 2021 on whether to favor the use of LEU.
Among the participants was Rep. Bill Foster (D-IL), a former Fermilab physicist, who argued that proceeding with HEU ( Highly Enriched Uranium) would set a dangerous precedent. “If all of the spacefaring nations start using HEU reactors in space, then this would involve utilization of a significant amount of weapons grade material,” he remarked…….
Alan Kuperman, a policy scholar affiliated with the Nuclear Proliferation Prevention Project, pointed to U.S. efforts since the 1970s to minimize the use of HEU in civilian applications, arguing they are “based on the logic of no exceptions.”
“If we say, ‘well, we’re going to have exceptions,’ then other countries are going to say, ‘well, we want exceptions too,’ and then the whole thing falls apart,” he remarked……..https://www.aip.org/fyi/2020/us-ramps-planning-space-nuclear-technology
USA wants nuclear power stations on the moon and on Mars
The U.S. Department of Energy put out the formal request to build what it calls a fission surface power system that could allow humans to live for long periods in harsh space environments.
The Idaho National Laboratory, a nuclear research facility in eastern Idaho, the Energy Department and NASA will evaluate the ideas for developing the reactor.
The lab has been leading the way in the U.S. on advanced reactors, some of them micro reactors and others that can operate without water for cooling. Water-cooled nuclear reactors are the vast majority of reactors on Earth.
“Small nuclear reactors can provide the power capability necessary for space exploration missions of interest to the Federal government,” the Energy Department wrote in the notice published Friday.
The Energy Department, NASA and Battelle Energy Alliance, the U.S. contractor that manages the Idaho National Laboratory, plan to hold a government-industry webcast technical meeting in August concerning expectations for the program.
The plan has two phases. The first is developing a reactor design. The second is building a test reactor, a second reactor be sent to the moon, and developing a flight system and lander that can transport the reactor to the moon. The goal is to have a reactor, flight system and lander ready to go by the end of 2026.
The reactor must be able to generate an uninterrupted electricity output of at least 10 kilowatts. The average U.S. residential home, according to the U.S. Energy Information Administration, uses about 11,000 kilowatt-hours per year. The Energy Department said it would likely take multiple linked reactors to meet power needs on the moon or Mars.
In addition, the reactor cannot weigh more than 7,700 pounds (3,500 kilograms), be able to operate in space, operate mostly autonomously, and run for at least 10 years.
“This may drive or start an international space race to build and deploy new types of reactors requiring highly enriched uranium.”
– Edwin Lyman, director of Nuclear Power Safety at the Union of Concerned Scientists
The Energy Department said the reactor is intended to support exploration in the south polar region of the moon. The agency said a specific region on the Martian surface for exploration has not yet been identified.
Edwin Lyman, director of Nuclear Power Safety at the Union of Concerned Scientists, a nonprofit, said his organization is concerned the parameters of the design and timeline make the most likely reactors those that use highly enriched uranium, which can be made into weapons. Nations have generally been attempting to reduce the amount of enriched uranium being produced for that reason.
“This may drive or start an international space race to build and deploy new types of reactors requiring highly enriched uranium,” he said.
Earlier this week, the United Arab Emirates launched an orbiter to Mars and China launched an orbiter, lander and rover. The U.S. has already landed rovers on the red planet and is planning to send another next week.
Officials say operating a nuclear reactor on the moon would be a first step to building a modified version to operate in the different conditions found on Mars.
“Idaho National Laboratory has a central role in emphasizing the United States’ global leadership in nuclear innovation, with the anticipated demonstration of advanced reactors on the INL site,” John Wagner, associate laboratory director of INL’s Nuclear Science & Technology Directorate, said in a statement. “The prospect of deploying an advanced reactor to the lunar surface is as exciting as it is challenging.”
Space archaeology, space junk and weapons, and long-lasting radioactivity
While the nuclear macho men plan more nuclear, and nuclear weapons in space, it seems that it takes a woman, Alice Gorman, to investigate the radioactive pollution on Earth and in space, due to these activities
Nuclear sites still dangerous in 24,000 years, say space archaeologists
Some nuclear tests were conducted also in outer space and nuclear fuel was employed as propellant for rockets. https://www.jpost.com/health-science/nuclear-sites-still-dangerous-in-24000-years-space-archaeologists-say-636379 By ROSSELLA TERCATIN JULY 26, 2020
Gorman said the issue presents two challenging elements: What materials can survive such a long time, and what form of language can be used to deliver the actual message?
“As for the first difficulty, we know that stones and pottery last a very long time,” she said. “But the second point raises a big archaeological question related to symbolic communication. If we look at rock art from 20,000 years ago, we can see that there are pictures of animals, but we do not know what those pictures mean. Therefore, it is possible that our current symbols to mark radioactive sites, the yellow [and] black sign, will be interpreted as an invitation to explore the area, rather than to keep away from it.”
If the UN Outer Space Treaty of 1967 prohibited nuclear weapons in space, the issue of its weaponization remains very relevant.“Recently, Russia tested an anti-satellite weapon, reawakening the debate,” Gorman told the Post.
She began to work in space archaeology following years of work focused on stone-tool analysis and the aboriginal use of bottle glass after European settlement.
Space archaeology deals with the same issues of regular archaeology, understanding material culture, human behavior and the interaction with the surrounding environment, Gorman said.
Gorman was drawn to space archaeology by the idea of exploring space junk, those many objects that cannot even be seen in the sky circling the Earth. Currently, she is working on the archaeology of the International Space Station.
The recent attempt by Israel to land a robotic unit on the moon with the Beresheet mission represents a very interesting development for space archaeologists, Gorman said.
“For many decades, the only material cultures present on the moon were the American and the Soviet one,” she said. “As new countries have started to reach the moon, this has changed, bringing more diversity to the field.”
Outer space beginning to look like a new area of nuclear conflict, according to Pentagon

Space Nukes
The U.S. Department of Defense released a new space strategy report on Wednesday. In it, the military revealed that it’s concerned that nukes detonated in space could wipe out its fleet of satellites.
It’s not a new concern, since space nukes were originally banned in the 1967 Outer Space Treaty. But all the same, Business Insider reports that the Pentagon is particularly concerned that China and Russia might strike — a dire warning for the future of combat.
The report specifically identified China and Russia as immediate threats. Such an attack could potentially devastate military communication networks as well as the myriad other systems that depend on satellites.
“The challenge of a nuclear detonation is that it creates an electromagnetic pulse and a signal that could then take out indiscriminately many satellites in space and essentially fry the electronics,” Deputy Assistant Secretary of Defense for Space Policy Stephen Kitay said at a press conference on the report, according to BI.
“That is a threat that we have to potentially be prepared for — a nuclear detonation in space,” he added.
If nothing else, the report is yet another sign that the idea of space remaining peaceful seems to be slipping away.
“I wish I could say that space is a sea of tranquility, but the fact of the matter is that space is contested,” Kitay said. “Outer space has emerged as a key arena of potential conflict in an era of great power competition.”
Trump’s ominous creation of the U.S. Space Force – for the purposes of war
How much will it cost? The vast costs will be shouldered by taxpayers, likely by slashing funding for essential social needs. The aerospace industry has suggested defunding “entitlement programs” to pay for “everything space.” That would likely include cutting Social Security, Medicare, and Medicaid among other social and welfare programs. In his proposed fiscal year 2021 budget, Trump is recommending $15.4 billion for the Space Force. The Space Force, if it is allowed to continue, will clearly be a multi-billion dollar annual affair.
Who will profit?
Raytheon is emerging as a major beneficiary of Space Force work. Perhaps not uncoincidentally, Mark Esper, Trump’s U.S. Secretary of Defense at the time the Space Force was announced, is a former lobbyist for the corporation. Other major contractors for the Space Force will be Northrop Grumman, Boeing and Lockheed-Martin, the world’s biggest military contractor.

Here’s a supremely unaffordable nuclear fantasy – reactors on the moon and Mars
NASA Wants to Go Nuclear on the Moon and Mars for Astronaut Settlement, SciTech Daily By AMERICAN CHEMICAL SOCIETY MAY 31, 2020 m It might sound like science fiction, but scientists are preparing to build colonies on the moon and, eventually, Mars.
With NASA planning its next human mission to the moon in 2024, researchers are looking for options to power settlements on the lunar surface. According to a new article in Chemical & Engineering News, the weekly newsmagazine of the American Chemical Society, nuclear fission reactors have emerged as top candidates to generate electricity in space.
Confusion over which American military satellites are “nuclear” and which are “nonnuclear.”
![]() Counterspace capabilities may meet dual-purpose command and control assets to create new risks. The Diplomat, By Ankit Panda, April 08, 2020 The Trump administration’s 2018 Nuclear Posture Review (NPR) drew much attention for the inclusion of language expanding the scope under which the United States might employ nuclear weapons. Specifically, the document observed that certain “extreme circumstances,” which “could include significant non-nuclear strategic attacks,” would rise to the level of meriting a nuclear response. In remarks delivered during an online video conference this week, Christopher Ford, U.S. assistant secretary at the State Department’s Bureau of International Security and Nonproliferation, discussed this language in the context of space security. Ford emphasized that for the purposes of parsing that bit of the 2018 NPR, American adversaries should understand that U.S. space-based dual-use (nuclear and nonnuclear) command and control assets qualified as what the 2017 National Security Strategy had dubbed a “vital U.S. interest.” Accordingly, Ford continues: “I need hardly point out — but I will nonetheless, for emphasis — that the U.S. National nuclear Command, Control, and Communications (NC3) architecture depends to some extent upon space-based systems.” He is clear therefore that nonnuclear attacks on this architecture would potentially rise to the level of a nuclear response: “Any harmful interference with or attacks upon such components of our space architecture at any time, even if undertaken only with non-nuclear tools, thus starts to move into ‘significant non-nuclear strategic attack’ territory, and would lead to a significant and potentially drastic escalation of a crisis or conflict.” Much of what Ford says here is not new or surprising, but his remarks offer one of the starker presentations of these ideas by a U.S. official in recent years — at least since the release of the 2018 NPR. The problem that arises is one of “entanglement,” where a crisis might escalate to the nuclear level inadvertently if an adversary — say China — is attempting to degrade U.S. conventional operations by taking aim at certain space-based assets. Though the United States openly acknowledges the role of space-based assets in nuclear command and control, there is no explicit tabulation of which American military satellites are “nuclear” and which are “nonnuclear.”….. https://thediplomat.com/2020/04/space-based-nuclear-command-and-control-and-the-non-nuclear-strategic-attack/ |

Critical comments on the claim that “Nuclear Energy Could Power The Trillion-Dollar Space Race”
Haley Zaremba’s final comment “” good news for public health and the environment coming out of the space industry”” left me puzzled.
Just exactly how are nuclear-powered space travel, and nuclear reactors on the moon and on Mars “good news for public health and the environment”?
A second question – nuclear reactors in space as a “trillion dollar” industry. Does this mean that it will magically somehow bring in trillions of dollars to the U.S. economy, – or, more likely, just add trillions of dollars to the national debt?
A final question – as the global economy, and especially the American economy, goes into freefall, heading for the greatest Depression ever, is this article just a rather sad joke?
Nuclear Energy Could Power The Trillion-Dollar Space Race https://oilprice.com/Energy/Energy-General/Nuclear-Energy-Could-Power-The-Trillion-Dollar-Space-Race.html By Haley Zaremba – Apr 09, 2020, While the economy comes to a grinding halt here on Earth, some investors, inventors, and dreamers are looking to the stars for their next business venture. The final frontier has been touted as a potential breeding ground for untold numbers of industries in key economic sectors including mining, tourism, research and development, data collection and analysis, to name just a very few.
In fact, the commercial potential of the space economy is allegedly so great and so untapped (for now) that Bank of America Merrill Lynch projected back in 2017 that the size of the space industry is due to explode, expanding to more than eight times its current size by 2050. Valued at nearly $400 billion now, that means that the space sector would reach a total value of nearly $3 trillion over the next thirty years.
We are entering an exciting era in space where we expect more advances in the next few decades than throughout human history,” a Bank of America report stated. Goldman Sachs and Morgan Stanley, however, were far more conservative in their projections than Bank of America Merrill Lynch, but the financial corporations still predicted that the space sector will expand to be a more-than trillion dollar industry inside of 20 years.
Even the United States Chamber of Commerce has been bullish on the space sector, stating that “total private investment is growing at a striking pace,” citing research by Bryce Space and Technology. “From 2000-2005, the industry received more than $1.1 billion in investment from private equity, venture capital, acquisitions, prizes and grants, and public offerings. By the 2012-2017 period, the industry had received more than $10.2 billion.” The Chamber goes on to say that, “the increased investment reflects the new opportunities in the commercial space sector and new startup ventures that did not exist a decade ago.”
Last summer, Oilprice reported that the nuclear industry was also angling to get a piece of the modern-day space race. “In just a few short years from now, the United States will be shipping nuclear reactors to the moon and Mars,” the report said, citing statements from team members from the Kilopower project, a collaborative venture from NASA and the United States Department of Energy.
The Kilopower project is a near-term technology effort to develop preliminary concepts and technologies that could be used for an affordable fission nuclear power system to enable long-duration stays on planetary surfaces,” said NASA’s Space Technology Mission Directorate. “In layman’s terms, the focus of the Kilopower project is to use an experimental fission reactor to power crewed outposts on the moon and Mars, allowing researchers and scientists to stay and work for much longer durations of time than is currently possible,” the Oilprice article summed up.
Now, just this week, an article from Space.com reported that “space is about to go nuclear — at least if private companies get their way.” The article is referencing developments from the 23rd annual Commercial Space Transportation Conference (CST), which took place in Washington, D.C. back in January. There, “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.”
NASA is no stranger to nuclear power. The agency has already used nuclear energy to power its Mars rovers, its Cassini mission probe of Saturn and its rings, and the two Voyagers up there exploring the edges of our solar system as we speak. The nuclear energy that powered those projects, however, relied “on the passive decay of radioactive plutonium, converting heat from that process into electricity to power the spacecraft,” whereas, according to the panelists at the CST, the future of space industry electricity lies in “Nuclear Thermal Propulsion (NTP), a technology developed in the 1960s and ’70s that relies on the splitting, or fission, of hydrogen atoms.” This form of nuclear fission would need low-enriched uranium, a much less hazardous material.
“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,” explained Space.com.
At least there is some good news for public health and the environment coming out of the space industry on the week that Trump announced that he wants to mine the moon.

Russia and the quest for nuclear power in space
Ekipazh: Russia’s top-secret nuclear-powered satellite, The Space Review, by Bart Hendrickx, Monday, October 7, 2019 There is strong evidence from publicly available sources that a Russian company called KB Arsenal is working on a new type of military satellite equipped with a nuclear power source. Called Ekipazh, its mission may well be to perform electronic warfare from space.
Regulatory issues
One of the Principles stipulates that nuclear reactors may be operated on interplanetary missions, orbits high enough to allow for a sufficient decay of the fission products, or in low-Earth orbits if they are boosted to sufficiently high orbits after the operational part of the mission. As explained earlier, the latter procedure was followed for the Soviet-era RORSAT missions, but it is highly unlikely that Russia would want to risk repeating the Cosmos 954 experience of 1978. In fact, the very presence of a “transport and energy module” on Ekipazh is a sure sign that it will be placed into an orbit high enough to prevent any harm. Before the nuclear-powered TEM is even activated, a liquid-fuel propulsion system may first boost the satellite to an orbital altitude of at least 800 kilometers, the same procedure that has been described for the one-megawatt TEM. During a recent question-and-answer question with students in St. Petersburg, Roscosmos chief Dmitri Rogozin confirmed that 800 kilometers is the minimum operating altitude for nuclear reactors. Judging from Russian press reports, Rogozin was actually replying to a question about Ekipazh, but seemingly dodged that by talking about the one-megawatt reactor instead.[38]
The results of this safety assessment, together with, to the extent feasible, an indication of the approximate intended time-frame of the launch, shall be made publicly available prior to each launch and the Secretary-General of the United Nations shall be informed on how States may obtain such results of the safety assessment as soon as possible prior to each launch.
Outlook
One also wonders if the Russians are biting off more than they can chew by simultaneously working on two nuclear electric space tugs (Ekipazh and the one-megawatt TEM). An attempt to streamline this effort seems to have been made by giving KB Arsenal a leading role in both projects in 2014, making it possible to benefit from the company’s earlier experience in the field and infrastructure that it may already have in place to test related hardware. Still, the two projects use fundamentally different nuclear reactors built by different organizations.
Physics Nobel Laureate predicts NO Migration to Other Planets
Humans will not ‘migrate’ to other planets, Nobel winner says, https://phys.org/news/2019-10-humans-migrate-planets-nobel-winner.html?fbclid=IwAR2JOS8NV_Z1FWLWspae0m611nKzYdZaHB7DQGvVEYIpDnYqYKgsDnPQCDc 10 Oct 19 Humans will never migrate to a planet outside of Earth’s solar system because it would take far too long to get there, Swiss Nobel laureate Michel Mayor said Wednesday.
Mayor and his colleague Didier Queloz were on Tuesday awarded the Nobel Prize for Physics for their research refining techniques to detect so-called exoplanets.
“If we are talking about exoplanets, things should be clear: we will not migrate there,” Mayor told AFP near Madrid on the sidelines of a conference when asked about the possibility of humans moving to other planets.
“These planets are much, much too far away. Even in the very optimistic case of a livable planet that is not too far, say a few dozen light years, which is not a lot, it’s in the neighbourhood, the time to go there is considerable,” he added.
“We are talking about hundreds of millions of days using the means we have available today. We must take care of our planet, it is very beautiful and still absolutely liveable.”
The 77-year-old said he felt the need to “kill all the statements that say ‘OK, we will go to a liveable planet if one day life is not possible on earth’.”
“It’s completely crazy,” he added.
Using custom-made instruments at their observatory in southern France, Mayor and Queloz in October 1995 discovered what had previously only existed in the realm of science fiction—a planet outside Earth’s solar system.
Mayor was a professor at Geneva University and Queloz was his doctorate student, when they made the discovery which started a revolution in astronomy. Since then over 4,000 exoplanets have been found in our home galaxy.
“It was a very old question which was debated by philosophers: are there other worlds in the Universe?,” Mayor said.
“We look for planets which are the closest (to us), which could resemble Earth. Together with my colleague we started this search for planets, we showed it was possible to study them.”
Mayor said it was up to the “next generation” to answer the question of whether there is life on other planets.
“We don’t know! The only way to do it is to develop techniques that would allow us to detect life at a distance,” he said.
Weapons proliferation risk of nuclear power in space
“There’s a lot of opposition in Congress and in nonprofit groups to any further use of highly-enriched uranium,” Kuperman tells us. “So if NASA wants to use highly-enriched uranium for this space reactor, it might provoke opposition to space reactors in general.
“NASA is introducing political risks to its plan by going this highly-enriched uranium route,” he adds.
The Trump administration ordered NASA in August to craft guidelines for safely using nuclear reactors on Mars or the moon. NASA is also moving ahead with its nuclear power ambitions under it’s Kilopower project to build a highly-enriched uranium reactor that could deliver 10 kilowatts of electrical power continuously for at least 10 years. The space agency launched a study in fiscal 2019 with the Department of Energy to determine how both low and highly-enriched uranium could meet different needs. But the agency “has not made a final decision on highly-enriched uranium versus low-enriched uranium for surface power,” according to NASA spokeswoman Clare Skelly……… https://www.politico.com/story/2019/09/27/nuclear-power-nasa-mars-alan-kuperman-q-and-a-1510896
Security dangers of nuclear energy in space
Nuclear Energy in Space: Nonproliferation Risks http://www.spaceref.com/news/viewpr.html?pid=54634, University of Texas-Austin, September 17, 2019
On October 17, experts from NASA, Congress, and reactor companies will gather in the nation’s capital to discuss ongoing development of nuclear reactors for space missions and the potential security risks.
The event is free, but pre-registration is required. For further details, and to register, please see: https://space-nuclear.eventbrite.com.
The program will feature Jeffrey A. Sheehy, NASA’s Chief Engineer in the Space Technology Mission Directorate. The keynote address will be delivered by Rep. Bill Foster (D-IL), the only physicist in Congress and a member of the House Science Committee.
Controversy centers on NASA’s choice of fuel for the reactor it tested in 2018 for use on a planetary surface: weapons-grade, highly enriched uranium. NASA scientists believe such uranium would enable smaller reactors, reducing launch costs. However, critics argue it could undermine decades of U.S. progress in reducing worldwide civilian commerce in this dangerous material, create a precedent that could help rogue countries obtain nuclear weapons, sharply increase security costs, impede NASA’s cost-saving collaboration with commercial partners who lack licenses for such uranium, and potentially disperse nuclear weapons material to adversaries in the event of a launch failure. They say that an alternative reactor fuel – low-enriched uranium, which is unsuitable for nuclear weapons – could reduce the security, economic, and political risks.
Last month, President Trump issued a Presidential Memorandum on the launch of space nuclear systems, which highlighted the security risk: “Due to potential national security considerations associated with nuclear nonproliferation . . . The President’s authorization shall be required for Federal Government launches . . . when such systems utilize any nuclear fuel other than low-enriched uranium.” In June 2019, the U.S. House of Representatives passed an appropriations bill that included an amendment by Rep. Foster, directing NASA to “work towards the development of a low enriched uranium (LEU) space power reactor.”
Ontario’s secretive role in helping Trump to nuclear weaponise Space

Unbeknownst to most Canadians, the Darlington nuclear power plant 70 kilometres east of Toronto has been playing a not-so-small role in the U.S. race to weaponize space
The 50th anniversary of the Apollo 11 mission added momentum to the new push to go farther into outer space than humans have ever gone before.
Ontario’s nuclear industry could receive both a reflected glow from the extraterrestrial travel hype and a new revenue stream. It could also potentially increase international nuclear-weapons proliferation.
Unbeknownst to most Canadians, the Darlington nuclear power plant 70 kilometres east of Toronto has already been playing a not-so-small role in the space race.
The plant has been producing radioactive plutonium-238 as fuel for spacecraft in NASA’s mushrooming space pipeline since 2017.
“We are proud to have Ontario play a part, however small, in this most noble of human endeavours,” OPG’s then-president and CEO Jeff Lyash said in a news release.
Canadian Nuclear Laboratories (CNL), which runs the Chalk River facility near Ottawa, another participant in the initiative, posted a “Success Stories” article on its website seven days later. It cautioned that “this opportunity is still subject to regulatory and licensing processes.” But it quotes a CNL official as saying “staff should take a lot of pride in the fact that we are key partners.”
CNL has continued communicating with other project stakeholders. But when NOW contacted CNL for a comment it responded on September 5 that it is no longer involved in the project. OPG has removed the news release from its website and did not respond to NOW’s request for information. Turns out a company called Technical Solutions Management (TSM) is steering the initiative now.
TSM is owned by former nuclear-industry executives Billy Shipp, Pierre Tremblay and Paul Spekkens. CEO Shipp told NOW in an August 29 phone interview that NASA has yet to give its formal thumbs-up.
“For us to get out ahead of our client [NASA], in terms of anticipated need [for plutonium-238], or making statements of their need, is not that professional on our part. So we really have been very low-key on this,” Shipp says when reached for an interview aboard a boat off Vancouver Island.
But he noted that U.S. President Donald Trump’s establishment of a Space Command makes the project more likely to proceed.
Plutonium-238 has long been used to fuel flight, via conversion into electricity of the intense heat the atom pumps out. The U.S. powered military satellites with it in the 1960s. NASA also harnessed it most recently to propel Curiosity Rover to Mars in 2011.
The steps involved for the manufacture of made-in-Canada plutonium-238 to supplement the U.S.’s production involves first synthesizing neptunium-237, plutonium-238’s precursor at the Pacific Northwest National Laboratory in Richland, Washington.
From there, the material is transported to Chalk River where it is put into bundles before it’s sent to Darlington and inserted into CANDU reactors. There, the neptunium-237 catches stray neutrons, transforming it into plutonium-238. The bundles are shipped back to Chalk River where the plutonium-238 is separated from by-products and packaged into pellets. The pellets are transported to Idaho National Lab where they are readied as ‘nuclear batteries’ for spacecraft engines. The current price of plutonium-238 isn’t public, but back in 2003 one kilogram was worth about $8 million U.S.
Gordon Edwards, co-founder and president of the Canadian Coalition for Nuclear Responsibility, says the form of radioactivity emitted by plutonium (namely, alpha particles) is highly toxic when inhaled but often isn’t picked up by radiation detectors.
For example, in November 2009, hundreds of workers at OPG’s Bruce nuclear plant breathed in plutonium dust (a by-product of nuclear-energy production) but the plutonium remained undetected for weeks. Many of the workers had not been given respirators. It was the largest preventable exposure of workers to internal radioactive contamination in the history of the civilian nuclear industry.
Even worse, says Edwards, is the fact the process used to create plutonium-238 can also be used to transform depleted uranium into plutonium-239, the key explosive in nuclear bombs.
“I grant that TSM’s plutonium-238 program does not fundamentally enhance this danger, but it does provide an opportunity to tell the public and politicians that if you can produce one kind of plutonium for the space program you can just as easily produce another kind of plutonium for a nuclear-weapons program, using essentially the same CANDU technology,” Edwards tells NOW.
However, no one inside the space or nuclear industries appears be seriously addressing these well-known problems. And there is plenty of money potentially available for a new plutonium-238 venture. NASA projects its research and development budget – including developing power and propulsion systems – will be $1.5 billion next year, rising to $3.4 billion by 2024.
TSM’s other co-owners, Tremblay and Spekkens, are well-placed to move such a project forward. Tremblay was OPG’s chief nuclear operating officer and president of OPG’s subsidiary Canadian Nuclear Partners. He became AECOM Canada Nuclear Operations’ president and CEO in August 2018. The American multinational is playing key roles in the multi-billion-dollar Darlington refurbishment. Tremblay started consulting for AECOM in June 2016; an industry article about this said the firm “has recruited key expertise that will undoubtedly position the company to play a key part in the massive nuclear power projects anticipated for Ontario over the next decade.”
Spekkens retired in 2016 as OPG’s vice president of science and technology and as chair of the CANDU Owners Group, a Toronto-based private organization that promotes CANDU use around the world. He then became a consultant and director of nuclear technology at Kinectrics.
He opined on the nuclear industry’s future at a June 2017 conference. In the abstract of his lecture, Spekkens says “this future will, of course, depend heavily on technology. But also (and perhaps equally) important will be non-technical considerations such as public acceptance, a pipeline full of qualified future employees, public policy in several levels of government, and of course, finances.”
The danger, the unwisdom, of highly enriched uranium in space

Since 2015, NASA has funded a group at Los Alamos National Laboratory to build what is called the Kilopower reactor, a nuclear fission reactor for space applications. The Kilopower reactor is a sodium-cooled fast-neutron reactor with a block core that produces electrical energy with Stirling engine heat converters. NASA plans to build four or five Kilopower reactors, each with a lifetime of 12 to 15 years and a continuous energy output of 10 kilowatts, which could meet the energy needs of a possible Mars base. This Kilopower fast reactor could be fueled with either LEU or HEU. While the LEU fuel for the Kilopower reactor would contain 19.75 percent uranium 235, the HEU fuel would contain 93 percent of this isotope, a degree of enrichment that is called “weapon-grade.” In the newest prototype, these two versions of the fast reactor have essentially the same design but differ by size and weight. Los Alamos published a white paper about the Kilopower reactor in August 2017 supporting the LEU designs, but half a year later the lab successfully tested the HEU design. In October 2018, Los Alamos published a second white paper that favored HEU on the grounds that it would have a lighter weight.
Indeed, the HEU version of the Kilopower reactor is lighter, but it comes with alarming risks: the block fuel element contains around 43 kilograms of HEU, enough material for a terrorist group to build a nuclear weapon. There is also a proliferation risk. Kilopower would establish a precedent that other states could use to justify their own production of weapon-grade uranium. That is why, over the last four decades, the United States has led an international effort to persuade research reactor operators to switch from using HEU to using LEU. Building an HEU-fueled space reactor would undermine those attempts and the nonproliferation policies that inform them.
There are other downsides beyond the security risks. For example, the use of HEU would exclude private industry from taking part in space-reactor research and development. Such a reactor would also be more expensive than the LEU version because of the high costs required to secure significant quantities of HEU during the development and the launch. Finally, an HEU reactor would be sure to stir controversy for the reasons mentioned above and would be subject to cancellation by Congress.
Beyond that, the main advantage of the HEU reactor may not actually be much of an advantage. In 2015 scientists from the Korea Atomic Energy Research Institute, and in 2018 scientists from the Colorado School of Mines, each published designs for different, lighter LEU reactor models with a similar power output to the Kilopower LEU version. Moreover, it seems realistic that we can expect further weight and launching cost reductions well before a Mars colonization mission could start.
Accident risks. Sending nuclear reactors into space is not a new idea. The Soviet Union launched over 30 into orbit during the Cold War to power radars that tracked the US Navy. The United States launched only one reactor, in 1965. Dubbed the SNAP-10A, it had to be shut down after only 43 days due to an electrical component failure.
Most of these reactors are still orbiting above us—but not all of them. For example, the Soviet Kosmos 954 reactor crashed to earth in 1978, spreading radioactive material over a large area of northern Canada. In total there is about one ton of nuclear material in orbit, and all of it is at risk of colliding with other space debris and coming back to earth.
Major accidents have occurred in over 20 percent of space reactor missions. That is probably one of the reasons why no country has launched a reactor into space since the Cold War. Given these issues, why not avoid radioactive material for space missions altogether? Perhaps solar energy should be the first choice for electrical energy in space. Most satellites launched into space get their energy from solar panels, as does the international space station, which has successfully operated for over 10 years with solar arrays that produce up to 120 kilowatts of electricity. The NASA Mars rover Opportunity ran for over 14 years powered by solar panels. In short, the difficulties of running a solar power system on Mars seem manageable.
If we really want to build a Mars base in the not-so-distant future, why should we go with weapon-grade uranium, with all its security and proliferation risks, when we have both the option of affordable alternative LEU designs and solar options that eliminate these risks? https://thebulletin.org/2019/09/do-we-need-highly-enriched-uranium-in-space-again/?utm_source=Newsletter&utm_medium=Email&utm_campaign=Newsletter09162019&utm_content=NuclearRisk_UraniumInSpace_09122019
