Duffy to announce nuclear reactor on the moon

Source: Politico

Transportation Secretary Sean Duffy will announce expedited plans this week to build a nuclear reactor on the moon, the first major action by the former Fox News host as the interim NASA administrator.

NASA has discussed building a reactor on the lunar surface, but this would set a more definitive timeline — according to documents obtained by POLITICO — and come just as the agency faces a massive budget cut. The move also underscores how Duffy, who faced pushback from lawmakers about handling two jobs, wants to play a role in NASA policymaking.

“It is about winning the second space race,” said a NASA senior official, granted anonymity to discuss the documents ahead of their wider release.

President Donald Trump named Duffy as interim administrator in July after abruptly withdrawing the nomination of billionaire Jared Isaacman amid a spat with the nominee’s ally, Elon Musk.

In this episode, the lunar nuclear waste explodes, hurtling the moon across the universe.

The people on the moon base survive and then have adventures, usually involving such things as falling through black holes and meeting powerful aliens with big egos and various personality disorders.

Powering things like colonies and stellar vehicle construction and low-gravity research, for instance.

Stuff that will be quite useful should humans ever want to colonize off-planet.

> Is it the first step towards some kind of colony or mining operation?

One could hope so.

> Perhaps and advertising billboard big enough to see from earth?

Perhaps. F47 would certainly approve of a huge image of himself orbiting the planet.

Seriously, the moon is our jumping-off point for further extra-terrestrial exploration and expansion. Much of the space colony tech will be developed and tested and refined in lunar colonies.

The availability of water will be an issue, with some ice-mining involved. Fortunately, lunar water contains a lot of hydrogen isotopes (deuterium, tritium) useful for fusion reactions.

> What protects the facility from meteroids uninpeded by atmosphere?

This will be a tough problem that will need to be at least partially solved to enable any long-term exo-colony development. Sub-surface colonies with minimal top-side facilities are the likeliest initial mitigative approach, although eventually humans might use something like the "iron dome" technology to intercept and destroy or redirect incoming meteors.

We shouldn't enter into such a venture lightly, pretending there are no hazards, nothing to learn, and no problems to solve. Unfortunately, F47's team of wastrel idiots likely will do just that.

I was born a month before Sputnik, and grew up with the space program. Always saw it as worthwhile, aspirational, the future of mankind.

Read a lot of classic sci-fi in my early 20's. This thread brought to mind "The Moon is a Harsh Mistress" by Robert A. Heinlein, in which the Moon is a penal colony and the inmates revolt with the aid of a supercomputer that becomes sentient.

Fiction, but I think our society needs the realm of ideas and aspiration for the future now more than ever.

Never, ever give Republicans the time of day when they ask how the fuck the country can pay for anything anymore. Clearly there's nothing they won't pay for as long as they're the ones in control. It's not a matter of fucking money. It's about values and priorities. Something this country no longer has.

How much nuclear fuel would you need, and how would you get it there?

My probably ill-informed answers: 1. lots and 2. with rockets blasting off from earth.

And I assume the payloads would have to be shielded. even if un-crewed, to protect the workers pulling this together for launch. To do any good shielding from gamma radiation has to be heavy. Then too, if the rocket goes boom on the pad, or explodes in mid air, or fails to reach orbit, or otherwise screws up.....

This is just another terrible idea in the annals of terrible ideas, especially since NASA is losing qualified people left and right. Imagine one of these missions being pulled together by some MAGA flunky, the engineering analog to RFK Jr.

Let's hope this dangerous fantasy quite literally never gets off the ground.

An already woefully underfunded NASA, that has had its budget cut by an additional 40% and has the greatest brain drain in its history as this administration declares war on education, science and scientists, is going to launch fissile material into space on a rocket that, if we have a single accident, could leave over half of Florida uninhabitable for the next 10,000 years? Have I got that right?

They were expecting many more employees to take the voluntary resignation but only got about 900 to do so. The latest news at KSC is that 6,000 people will be laid off because of the budget cuts. This is just at KSC. Can you imagine the ripple affect of that many in Florida being let go? My son is a software engineer at NASA and he will just leave the state if he's one of the layoffs. He hates Florida anyway. He's told me morale is extremely bad right now and they want to launch Artemis in January.

Mon Aug 4, 2025, 08:15 PM

.... which, of course is what a nuclear reactor does. But I don't understand, and I can't find it explained anywhere, how the heat gets turned into electricity. I don't think they will be operating a steam turbine on the moon.

I can think of two possibilities...

* Thermoelectric, based on the thermocouple principle. This is a tried and true space technology, but is inefficient. https://en.wikipedia.org/wiki/Thermoelectric_generator

* More speculative, a Sterling engine to produce mechanical power, and then drive a generator. I'm not sure this would work. https://en.wikipedia.org/wiki/Stirling_engine

Anyone have any clues?

Tue Aug 5, 2025, 03:30 AM

The water that flow through the reactor and turbines is a closed loop. You'd have to transport the water there too, of course (extracting it from rocks there would need energy - and if you had that, you wouldn't need the reactor). The cooling would have to be done without evaporation, or transfer of heat to river/sea water that we do with Earth-based reactors, but I think that would be possible by radiation - certainly during a lunar night, and maybe during a day too (with shading? A proper engineer of scientist might be able to say if it's feasible).

There are craters on the moon with areas that are perpetually in shade, and even may harbor water ice. So if you place it properly you may be able to have a cold zone day or night.

The moon has dark periods when solar would not be effective. It would be used, but it would not be continuous. I guess battery storage could be used but I don't know how practical that would be.

The other issue I saw mentioned is that whoever puts a nuke on the moon could reasonably declare an "exclusion zone" which would be similar to staking out a territorial claim.... but perhaps in a way that could avoid space treaty complications.

My answer is yes, they can (and will) monitor reactors on the moon to that degree. That can be done now, but the link I sent about LunaNet shows the next generation of space based communication infrastructure, focused specifically on the cis-lunar domain. It is in development right now, and I have had a small part in moving it forward over the years.

The reactors themselves will be much more fool proof than this:

119. "Air cooling" is not exactly a lunar option, with no air
Tue Aug 5, 2025, 02:35 PM
Aug 2025

It does seem that a method of cooling a lunar reactor is still under debate:

Russian space agency Roscosmos has announced its intention to build a nuclear reactor on the lunar surface in collaboration with the China National Space Administration. According to Roscosmos director general Yury Borisov, “Today we are seriously considering a project—somewhere at the turn of 2033–2035—to deliver and install a [nuclear] power unit on the lunar surface together with our Chinese colleagues.” The reactor would apparently be used to supply power to the Russian-Chinese International Lunar Research Station (ILRS), plans for which the two nations unveiled in 2021.
...
Borisov, who is a former deputy defense minister, stated that the lunar nuclear reactor “should be” constructed autonomously by robotic technology, rather than be built by humans. He described the reactor plans as “a very serious challenge,” noting that a solution to cooling the proposed lunar reactor has not yet been found.

https://www.ans.org/news/article-5894/nations-envision-nuclear-reactors-on-the-moon/

It might be a lot easier near the poles, where the maximum daytime temperatures can be below the boiling point of water - see https://www.sciencedirect.com/science/article/pii/S0019103516304869
That might make some form of radiator a possibility.

There is no water on the moon (maybe at the poles?) - how would the reactor be cooled?
Who would be available to monitor a meltdown or other catastrophe? If the personnel there are killed, you can't get more people there instantly!
If the moon is destroyed or badly damaged, the Earth's tides would be completely destroyed - perhaps massive floods or tidal waves.
We do not know the full functions of our moon, or even if it is natural! Some old civilizations say that the moon was "towed into place." NASA discovered that the moon "rang like a bell" upon a heavy impact. Hollow? What could be inside? How is it that the moon PERFECTLY fits the area of the Sun during a solar eclipse?
Maybe we should think this thing through a bit . . .

This has been a hot topic here before!
https://www.democraticunderground.com/122878972

https://www.democraticunderground.com/100216096617

This is part of Project Artemis, a long term vision of returning to the moon.
Initial inquires for a power station project called “Fission Surface Power Project” were initiated as far back as 2021.
“ NASA is collaborating with the U.S. Department of Energy’s Idaho National Laboratory to establish a sun-independent power source for missions to the moon by the end of the decade
Providing a reliable, high-power system on the moon is a vital next step in human space exploration, and achieving it is within our grasp,” Sebastian Corbisiero, the Fission Surface Power Project lead at the lab, said in a statement.”


https://apnews.com/article/technology-science-business-moon-idaho-ae35ae200a46bec0ca215bc88923181d#

Last month, under fears that Cheeto was cutting NASA funding, hundreds of NASA employees and former astronauts issued the Voyager Declaration, advocating continuing NASA’s research and exploration goals, which includes Project Artemis.

“ Dear Interim Administrator Duffy,
In light of your recent appointment as Interim NASA Administrator, we bring to your attention recent policies that have or threaten to waste public resources, compromise human safety, weaken national security, and undermine the core NASA mission. We, the signatories of this letter, dissent from these policies, and raise these concerns because we believe strongly in the importance of NASA's mission, which we are dedicated to uphold.
Major programmatic shifts at NASA must be implemented strategically so that risks are managed carefully. Instead, the last six months have seen rapid and wasteful changes which have undermined our mission and caused catastrophic impacts on NASA's workforce. We are compelled to speak up when our leadership prioritizes political momentum over human safety, scientific advancement, and efficient use of public resources. These cuts are arbitrary and have been enacted in defiance of congressional appropriations law. The consequences for the agency and the country alike are dire.”

Tue Aug 5, 2025, 05:45 AM
Aug 2025

...while a number of fission reactors have operated in orbit - one crashed into Northern Canada some years back, as I remember - there is absolutely no good reason to put a fission reactor on the moon.

I note that the seismometer left on the Moon by one of the Apollo missions is nuclear powered, with a radiothermoelectric generator (RTG) powered by 238Pu, and almost all of the deep space missions have been similarly powered, they had a purpose and required low power. (The Voyager missions are now heading out of the solar system and still communicating on nuclear power.)

From my perspective this is a typically nutty idea put forth by these people as a distraction as the continue the engineering the collapse of the United States.

We need, desperately, nuclear reactors on Earth for now, not much else.

I note, with some regret and dismay, that many of the posts in this thread feature the usual ignorant antinuclear paranoia, including, if I read this right, blowing up the moon. One sees these things and one doesn't want to believe it.

Another very, very, very amusing one that I believe I saw in very quick scan is that a nuclear reactor on the moon would make the moon uninhabitable. Did I really see that? Um, um, um...

The moon is in a fairly intensive radiation field. All of outer space is.

Tue Aug 5, 2025, 11:09 AM
Aug 2025

I've been meaning for a while now to ask your thoughts on something, and figure now is as good a time as any.

What I'm about to describe is my principle worry about building lots of nuclear reactors here on earth.

I think that many of the technical issues that folks raise in opposition, for instance the issue of spent fuel and other waste have--at least on paper--technical solutions available to us today. There are problems of course, but we have the technology in place to deal with these issues, providing the funding and politcal will is there as needed.

It's the political/social/human issues, the ones I'm about to describe, that worry me, and which seem to me less amenable to solution.

I'm thinking, for instance, of what's happening now in Ukraine. We had Russian troops digging trenches inside the Chernobyl exclusion zone, thus re-exposing dangerous materials. But even worse, in terms of potential danger, has been the threat to the Zaporizhzhia Power Station, the largest in Europe and one of the 10 largest plants in the world. For a while the plant was caught between warring armies, and as I recall there were concerns that a stray shell or drone might hit the plant, either by accident or deliberately. And it wasn't even necessary for such a strike to put the plant and the region around it at risk, since there was a period when the plant was understaffed--perhaps dangerously so--because many workers didn't relish the idea of commuting through a war zone to get to work. At least this was how this was described in the press.

And the idea of a deliberate attack on a power station isn't all that far fetched. Evidently the Russians fired a drone at the containment arch that now covers Chernobyl, punching a good size and thus compromising the air pressure system that keeps air from escaping in the event of a wider breach or accident of some kind.



You might say that we can try to build reactors only in regions of relative political and social stability. But how can we guarantee such stability for the time frames this would entail--decades or more, probably far more? Back in the 1970s and '80s, when these power stations were built, most everyone assumed the USSR was among the most stable regimes on the planet. And yet here we are.

I can't think of a single region on earth that has been politically and socially stable for the length of time needed here, aside from Antarctica.

Granted, any major piece of infrastructure is vulnerable to the ravages of war. Films of post-war Europe certainly bring that point home. But the effects of a nuclear plant being bombed or rocketed are so severe that even a single instance would be catastrophic. The only other example I can think of that would be at all comparable to blasting a nuclear plant would be smashing a major dam. The British did this to the Ruhr dams during WWII, which caused major flooding and killed perhaps thousands of people. But disastrous as that was, the cleanup was a fairly straight-forward affair, and those regions that were flooded now appear to be entirely unscathed. I don't know if that would be at all the case in the event of a similar attack upon even a smaller nuclear power plant.

I wonder: what are your thoughts on this? A while back you posted about proposals to build plants across Africa, which raised this issue for me, but even before that I'd been mulling this over as a concern.

Are my worries about this unfounded? Is there a way to construct plants so that they would be invulnerable to any surrounding upheaval--civil war or war between nations such as between Iran and Iraq, intense civil unrest such as we've seen in recent decades in Yugoslavia or Rwanda? And even if the physical plant could be made secure in all circumstances, how do we ensure safe levels of staffing for the life of any plant, so we don't see problems such as what we've seen in Ukraine?

A long winded post, I know. But for me this is the one huge stumbling block I see to building the number of facilities needed to replace carbon based forms of energy. All the other issues, like I said, seem solvable, at least on a technical level. But humanity is so unstable, human beings so often destructive, and the potential for even one major plant to cause widespread and long lasting damage should it fall victim to that sort of human depravity, I have difficulty seeing how we can guarantee with any degree of certainty that such an event could never happen.

Is this something that has been considered by engineers such as yourself? Are there any fixes for this that you know of?

Thanks for reading through all this. I'm very much looking forward to your reply and the possibility that my worries in this regard might be put to rest.

Best wishes--

And it won't go BOOM is something goes wrong.
