China's New Space Reactor 'Will Be 100 Times More Powerful Than a Similar Device NASA Plans To Put on the Surface of the Moon by 2030' (scmp.com) 134

Hmmmmmm writes: China is developing a powerful nuclear reactor for its moon and Mars missions, according to researchers involved in the project. The reactor can generate one megawatt of electric power, 100 times more powerful than a similar device Nasa plans to put on the surface of the moon by 2030. The project was launched with funding from the central government in 2019. Although technical details and the launch date were not revealed, the engineering design of a prototype machine was completed recently and some critical components have been built, two scientists who took part in the project confirmed to the South China Morning Post this week.

To China, this is an ambitious project with unprecedented challenges. The only publicly known nuclear device it has sent into space is a tiny radioactive battery on Yutu 2, the first rover to land on the far side of the moon in 2019. That device could only generate a few watts of heat to help the rover during long lunar nights. Chemical fuel and solar panels will no longer be enough to meet the demands of human space exploration, which is expected to expand significantly with human settlements on the moon or Mars on the agenda, according to the Chinese researchers. "Nuclear power is the most hopeful solution. Other nations have launched some ambitious plans. China cannot afford the cost of losing this race," said one researcher with the Chinese Academy of Sciences who asked not to be named as they were not authorised to speak to the media.

    Flunkie: Why?

      The Soviet Unions greatest accomplishment was the Apollo program.

      • More appropriately the USSR's greatest failure was the desire for spectacles. Now it is too early to tell if China is going to go down the same road, but bigger without a reason isn't useful. That being said, the USSR boasting about it's "accomplishments" in space spurred America to even greater heights.

        Of course the current crop of "EBIL BIG GUBBERMINT CAN DO NOTHING RIGHT!" politicians will probably f*ck that up royally.

          China used to do things unannounced, then only talk about it when it succeeds. They opened up a bit more lately with the civilian space program, but still lacks the hype you see from the likes of SpaceX.

      It's a question of budget. NASA is basically pork as far as the people in control of the purse strings are concerned.

      In China space is a prestige issue and a way to push development of technology as their economy transitions. They are aware of the benefits that the Space Rate bought to the USA, despite the cost.

      So naturally the goals are a bit different in scale.

      • From a report of "Space Foundation", space investment from the US is 51.8B (57% in global), while China is 13.3B(15%), all other countries are 25.1B. As for military space investment, the US investment is more than 80%.
        It's clear, the US is still investing space tech, much more than other countries. China is just developing in a normal scale and pace. The US is going to lead in space tech for decades.
        • Maybe GP was talking about the attitude towards it. I can't speak to what that's like in China, but here in the USA it seems that a small percentage of people are still bullish on space, but most are ho-hum at best and many actively think we should spend nothing on it because we have things here on Earth that they want to spend money on. Like fucking walls, as if those were going to help with anything.

          OTOH how much you spend is important but not the whole story, here in the USA we can waste money like nobod

    The way the media treats claims out of China as credible is long past its shelf life. Look at that subheading:

    Prototype design for a powerful nuclear reactor for the space programme has been completed and some components have been built, according to researchers

    The "some components" part would be true of literally anything you can possibly build, ever. Even attaching the word "critical" means nothing in this context. You wouldn't put something on space hardware at all if it weren't critical. And the bar for "prototype design" (not prototype construction...just design) is so low, there's not much that couldn't claim it from 1960s and 1970s archival research.

    Also, real projects of such a magnitude with national backing have dates attached to them. You'd get a target timeline from a real source long before you'd get enough technical details to make the story credible, even if the target was politically-motivated and silly.
    • But it's the perfect headline. It plays equally well to Americans who are irrationally afraid of China as it does to those who want to dislike their own country. There are probably a few nerds who are just interested in the technology, so it's a least a good headline for Slashdot.
    • China is making a bid to replace America as the dominant nation in the world. It has to in order to maintain it's economy. To become dominant, it's not a question of GDP, or military might, or cultural exports; they can never compete with the US on those terms (maybe GDP but then again there are serious weaknesses there). No, you're dominant because every one else in the world accepts it as fact. So they put out these headlines to emphasize the story that they are catching up, or caught up, and on the v

      Given that the context here is nuclear device sent to space by China, they do not unless those were in Chinese spacecraft.

    • An RTG is not considered a "nuclear reactor". So, no they do not count.

      An RTG is a blob of warm/hot material, and a Peltier element creating a low current from that heat. Extremely inefficient.

      A reactor is considered to be much much more complex. As in steam, liquids, cooling, probably turbines.

      But I'm pretty sure you could come up with new designs, e.g. sintered ceramic sterling engines.

      • The Fine summary cited Yutu 2 as the only thing in space with a nuclear device. Its device seems to be nothing more than a blob of warm material. I wasn't suggesting that RTG is a reactor, but that the Yutu 2 is not the only thing with a "nuclear device" onboard.
        • no, TFS said Yutu 2 is the only Chinese spacecraft with a radioisotope heater. The US and Russia have launched a bunch of RTG-powered spacecraft and a few with nuclear reactors.

      • "An RTG is a blob of warm/hot material, and a Peltier element creating a low current from that heat. Extremely inefficient."
        Also, extremely cheap compared to the full blown device.
        And relatively light compared to other ways to produce electricity (it won't beat solar in Earth orbit).
        Not to mention that it basically can't fail (it loses electricity production in time due to both the radioactive isotope getting less radioactive and the thermoelectric getting "aged", but it is some 80% in 10 years.

      I guess they mean on the moon, not in space. Lunokhod 1 had a radioisotope heater but it didn't generate electricity.

  • Just how big a population and manufacturing center do we think we can support with 10 kW? It seems like we're planning to go on a camping trip. If we have any installation that has to endure the lunar night, this will be the only power supply for much of the time. A megawatt seems like a good prototype. It is not even enough to supply a single TBM for tunneling out the base.

      Well you use the heat as well, instead of using electricity to produce heat. That means the electrical output of the reactor maybe 1MW but the thermal output could be closer to 3-4MW considering mechanical losses.

      That would also mean you could run the reactor harder during lunar night (when you would need more heat anyway) to charge a whole bunch of batteries that you would use during the day when you use less heat. Also you could use the lunar regolith itself to conduct heat and increase the efficiency

    • I doubt the first Martian base will be underground. It's a modular prototype maybe? if it works they can build more or scale up. Either way the first people living on the moon will be above ground till infrastructure is built. Stays will be comparable to the ISS.

    • A megawatt can definitely power a small TBM that operating on the moon. Reference: https://www.tunneltalk.com/Tun... [tunneltalk.com].

    • A megawatt is still about 10x the continuous electrical power available on the International Space Station.

      Obviously 1MW can't support a massive lunar base, but then we can't currently build a massive lunar base either. You gotta start somewhere.

    • I don't know where they got the 10 kW number from. According to this Slashdot story [slashdot.org] from just a few days ago, NASA is proposing to build a reactor that generates "no less than 40 kilowatts".

      Anyway, I don't think any of these is meant to support a big population. You start small and scale up. This is just the first version.

      Another thing to remember about the moon is that you get abundant solar energy for two weeks, followed by no solar energy at all for the next two weeks. Any big lunar facility would pr

    So it's best to read every piece of news like this with a large grain of suspicion that it's directly generated CCP propaganda

    • by djinn6 ( 1868030 )

      I would say any positive news coming out of China has CCP's stamp of approval on it. However, that does not necessarily mean it's false. They've said many things that did turn out to be true too.

    I trust NASA to manage the design, launch, and delivery of a small lunar-bound nuclear reactor with reasonable care (yes, despite the shuttle program) and nearly negligible risk to human life.

    I do not trust China to do the same, especially with a much larger device.

    • From 1981-2011 the shuttle flew 132 crewed missions. The crew was lost in two.

      Considering spaceflight involves sitting on top of 3 million pounds of rocket fuel while it's *on fire*, that's a pretty decent success rate.

      One by can certainly find things to criticize with the shuttle program. The safety record isn't crap, though.

    • I trust NASA to manage the design

      I trust NASA with exactly nothing. They can't manage themselves let alone projects.

      How much of ALL of NASA's (and I'm going to use this word generously) "efforts" have been uttterly wasted? My direct interest with NASA started with the shuttle. Like most everyone else, I had a love affair with them in the 80s over the shuttle and Voyager and all the rest. I resisted disillusionment with the revelations after Challenger. But then came the Mars Climate Orbiter, the Hubble mirror scandal, Columbia, Curiosity,

    Anyone in the west, media included who thinks the CCP allows unnamed sources to leak info like the western lame stream media use for sources is an idiot.
  • As one of the elderly folks here I cannot help noticing how the CCP rhetoric and actions parallel those of the CCCP. It seems they may have removed the wrong C leaving the one for "Communist" in place. It's the nature of Communist regimes. it's so strong it breaks through all cultural barriers and you get the same old same old repeated every time. Children, it's not gonna work this time, either. But, really, Xi "Poohbear" Jinping and his CCP are just so comically like the Russian Commissars it's funny despi
