[@Jordan.Vaughn]

Like 15 years ago, when I learned that all of our submarines and navy ships were powered by nuclear reactors, I immediately thought, “why is nobody doing this in the private sector”. It’s only now that I’ve discovered the reason: existing power structures and narratives. That will be the greatest barrier to Radiant’s success.

[@pindapoy1596]

@Jordan.Vaughn A bigger barrier is the self inflicted disaster of having abandoned our industrial capabilities. The proposed reactor and many others of different designs may turn out to be very effective and efficient BUT the manufacturing capability is not there and it is the revival of this capability that will prove to be the key to any nuclear power plant success. Experimental models and research in general are just the starting phase but we need realism if such reactors are not to remain "interesting toys". And it is not only the manufacturing capability that may turn out to be a stumbling block. Our lack of craftsmanship is also a huge problem. These complex machines need a highly skilled workforce but as a consequence of our industrial decay, that workforce has shrunk to dangerous levels and nobody is interested anymore in having "greasy hands". And finally, it is interesting that you bring up the nuclear navy. You certainly know that its development and growth was due to a remarkable man, Admiral Hyman Rickover. I really wonder if people like that who did not fear to swim against the tide and keept getting things done though personality strength will ever surge again in an era of political correctness and DEI control of industry and business.

[@tony-does-stuff]

Not all Navy ships. Only Submarines (SSNs / SSBNs) and Aircraft Carriers (CVNs). Everything else is still conventional, to include LHAs and LHDs. There was a period of time in which some of the smaller ships were nuclear powered, but that didn't last long.

[@fsteddy6576]

I don't think its due to nobody wanting greasy hands. I think it has more to do with the fact that submarines have endless supply of salt water for cooling purposes where other land based applications don't AND more importantly capitalism is already failing North America in many ways; I don't want to imagine how poorly a job the gov't would do regulating powerful Companies while they play with nuclear reactors.

[@pindapoy1596]

@@fsteddy6576 You are mixing everything in one big salad bowl. Greasy hands means that we have lost craftsmanship to build the readyors in factories and then placing them at the proper sites creating electricity generating plants. Salt water cooling and capitalism again a re a wierd mixture of ideas. We do not really know how the new reacors will be cooled. Period. End of technical discussion. Yes capitalism is failing and the cause is largely corporate greed. Shifting jobs and industrial production abroad for the sake of increased profits. The poor performance of Government regulatory agencies is well known but the influence of lobbyists and the power of "I give you and you give me" should not be ignored. If you watched the recent inquiry about power loss in Houston following a relatively low intensity storm, you could easily understand that the questions were not sharp and the answers were meaningless. At some point in time everybody was discussing tree pruning along the power lines right of way but that is minor compared to the fact that we do not produce anymore the required electrical equipment to improve the network and even if we had the components, there is no desire to invest..

Brilliant Radiant! I did not quite support or was keen in nuclear reactors since my school days in the 1970's but after viewing your video on the subject & the over- all view of your enthusiastic, radiant, technical explaininations it makes some sense as long as there is guarantee that no radio-active materials are released to the atmosphere in case of cooling failure or some other faults in the system or introduced faults to the nuclear reactors. If that safety aspect is 110% guaranteed then I am all for this potable, robust nuclear system. I really would like to witness your nuclear reactor system working in real life conditions & would be looking forward to your launching in 18 months time in 2028. You are also most welcome to trial this new nuclear reactor at my village in Nubia, Hanza Bay in Madang Province. Greetings from Madang, Papua New Guinea!

[@lucianoag999]

Well they didn’t go much into safety details. What they said is rather trivial about what needs to be done. There are other aspects though. Helium is a non renewable resource. What about shielding against terrorist threats, like an airplane or drone strike? The amount of radioactive material is enough to contaminate and make large areas inhabitable. What do they mean by mass production? If you see the problems that can be cause by orphan sources, imagine having a couple hot containers of the thousands produced , just abandonded. What happens if they go bankrupt? Who takes care of and pays for the old reactors and the cost of dismantling them? How will IAEA be able to control them? How are they avoiding the transmutation of the fuel elements into weapon grade material? What happens if someone steals them? What about radiation embrittlement of the materials during time? Are they also testing it? I have a lot of questions and very little answers on their website.

[@2012-JAF]

SAFETY! . . . or LACK thereof: NO consideration at ALL for each reactor's end-of-life recycling/disposal requirements.

I’m assuming that a reactor that small would require a fuel enriched to around 20% or more, similar to what nuclear submarines use (also a compact reactor design). That kind of enrichment more than warrants controls to ensure the fuel doesn’t get into the wrong hands.

The last thing a roared deployed base needs is a small nuclear reactor. This is a huge benefit for mining or remote locations but to say it's going to save lives in military operations is legit insane. I was a Naval nuclear operator and have a professional background in nuclear engineering. If a forward small generator got hit it would make the surrounding base unlivable not forever, but for ten years would lose the full funding of that base. Bad idea militarily or we would have done it. The army had a program for nuclear tanks and the air force had one for nuclear aircraft (the airforce one never took off, and the army one blew up).

[@bry2k]

If everything a base needs could be run on electricity rather than all the equivalent fuel and supply lines, that could be a very beneficial trade-off. How hard would it be to dig a hole and bury one or more of these conex-trailer sized things when setting up the base, thus protecting it from most threats? For the military, not hard at all. Seems plausible. As for "losing the full funding of that base"...did you not see what Biden did when we left Afghanistan? Since when does the US military give a crap about retaining its assets? These guys are talking about the military idea for one obvious reason: because the military spends $$$ like there's no tomorrow.

[@elongatedshrew5902]

That's why the generators are so small, it's harder to hit and much less fuel that it could potentially spill if attacked. The area gets exponentially bigger in a circle when expanded like a reactor, this reactor is exponentially smaller if you get what I mean so that there's going to be little spill at all and easy to clean up. I don't think it's as bad as you're thinking but I see your concern.

Nuclear reactor powered planes, automobiles, and homes make as much sense as nuclear powered submarines and ships IF the scale is appropriate to the use case and risk.

Once we pass this reasoning we will see nuclear implementation at scale.

[@johnconner4695]

Sorry you’re a little off. You can come in and clean up the area which would make it functional again. Why you think it stay non livable for ten years is wired. The Army would just stand up units that would go handle these things with robotics in mind. This is just a simple engineering issue that can be solved but people keep acting like it’s impossible to integrate this stuff into military application when it’s done on military ships for ages. No we haven’t done it because an incident happened and instead of fixing what happened we just gave up. The idea that if it’s beneficial we would do it is like saying the military uses common sense and things that are of benefit when we know that’s a lie because it’s run by humans. If you wanna move to the next step and actually save money and be more efficient then Nuclear is a way and maybe the way to move forward. There will be major issues and maybe people die but then you fix the issues with better engineering and implementation which will come with time and failure.

If one of these reactors gets hit by a tornado, hurricane, missile, or mortar it's toast and it will leak substantial radioactivity. That doesn't mean this is a bad idea, but it's only good for very niche applications.

[@kokofan50]

It’s designed to be passively safe. The worst thing to happen is some pebbles get skattered around

[@EddieTheH]

​@@kokofan50 No, the worst thing that happens is it irradiates everyone around it. You can make the reactor smaller but the radiation still requires the same amount of shielding.

[@bartroberts1514]

The use cases mentioned in the video are jaw-droppingly awful. 1. De-orbiting from space, or launch failure. 2. Place in hot military combat zone. 3. Place in urban setting where they're one metal-bandit with an angle grinder and a truck away from their unit going into a scrapyard crusher. This isn't a recipe for disaster; it's a whole cookbook.

As a nuclear safety and licensing analyst I would love to be a part of this. So exciting! I have been waiting years for the nuclear renaissance to begin. The future is finally here. You've earned another subscriber.

[@upstrader]

No discussion of capability is complete without touching on how many KG of reactive product are created, and the time till those parts become safe again. We can talk about how reactor design and impementation has moved on since the 60's but we are not talking about the elephant in the room for fear of putting the average Joe off. Perhaps the small scale reactors produce less highly radioactive waste per GW, perhaps not. Lets be told. We need a new SI unit (Becquerel* KG * Years till inert) per GWH produced at a first guess. Basically the ratio of time adjusted radioactivity risk vs power production over reactor lifespan.

[@NanneWielinga]

Indeed. Plus we need to put a price on dealing with the nuclear waste. Because I think it would be much cheaper to deal with nuclear waste of one big reactor versus 10 smaller ones. As you would have to move and collect nuclear waste from these 10 to a central space.

[@andrasbiro3007]

The amount and type of waste are identical, because it uses the exact same fission process. But it's a trivial amount, no concern, unless it gets out into the environment. Not having water in the core, and using TRISO fuel, makes it practically impossible to leak any radioactive stuff. As for risk, it's really just a few hundred years, after that it's more dangerous chemically. Don't eat it, and you'll be fine. Also, most of the "waste" is actually unburned uranium, and transuranic elements, like plutonium. These can be used as fuel. The U-238 needs a different reactor type to burn, most of the rest can go back into the fresh fuel. Ironically, these are the less radioactive parts of the "waste". The really nasty stuff are the fission products.

[@andrasbiro3007]

​@@NanneWielinga If I understood correctly, they use 30% enrichment. Conventional reactors are more like 3-5%. This means up to 10x more lifetime for the fuel, 10-20 years. Assuming they can burn all of it, but I think they should be able to. And then the core is small enough to be transported, so they'll probably do just that, take back the spent cores to a processing facility in a remote location, where the disassembly can be done safely. The waste could then be treated as any other kind. Ideally you want to recycle most of it.

[@upstrader]

@@andrasbiro3007 I disagree. In addition to fuel, you have to consider irradiated core parts. Just the relationship of having many smaller reactors is going to mean that you have have more surface area/parts that are going to need treating as hazardous, and this ratio of mass of parts for GWh is going to be lower than for large plants - IE not identical. assets.publishing.service.gov.uk/media/63e24c2e8fa8f50e805a3e66/2022_Materials_Report_-_010223.pdf Using the above UK figures for spent fuel there is ~7000 tHM (tonnes heavy metal) of irradiated fuel currently in the stockpile. and approx 113 tHM of plutonium - none trivial! Talking about plutonium as a trivial problem is nonsense, its one of the most toxic elements. I'm not sure but I dont think it existed before 1945, and is now measurable in adults. It similar to the slow deaths caused by coal - hard to quantify. Now this is all a push back against you attempting to trivialize what I feel should be central to the new wave nuclear discussion, and better to be had than not. My original point was that some important aspects are not being discussed in the S3 video. In terms of your line about it being impossible to leak radioactive stuff, I think the reactor model uses deflectors to contain/release neutrons. Here is a failure mode - error,fault or lack of site security causes these to contain when they should be releasing, giving a criticality, overheat and containment breach. There is no concrete sub structure for containment. I'm actually pro nuclear (in the sense that its probably the only realistic option given people wont want to give up luxuries based on cheap energy) but only if the long term storage problem for the worst waste should be explored in tandem.

I understand that the control blades are controlled by an active system (please correct me if I misunderstood). However, it would be more reliable for this control to work passively. Even if it is backed up, failure of active mechanisms will also cause a catastrophic accident (especially in seismic effects or station blackout case). The activation time constant of the control blades is also very important. In expected/unexpected accident situations (AOO, DBA, BDBA or SA) where the temperature will increase aggressively, how much time is needed for the I&C systems to understand this and for the motors that will provide the movement of the control blade platforms to be activated? If we consider that the chain reaction will increase exponentially, this period should be quite short. My second question is about the online reactivity control mechanism. Is there another control mechanism to control the loaded excess reactivity at the criticality level? Or is this also provided by the control blades?

There have been historical micro reactors used, mostly Military projects, the issue back then was negligence and having arguably untrained personnel maintain them and then disaster inevitably struck. If you look into the list of Nuclear reactor incidents in the World, you’ll see a few of them like the incidents at the Santa Susanna Field Lab back in the 50s / 60s north of Los Angeles.

[@eriklondon2946]

For those unaware Gen IV nuclear power (which is what this idea is) is the HUGE benefit that we have needed since the 1970's. Gen IV includes using Molten Salt Reactors (MSR's) as well as Small Modular Reactors (SMR's). Molten Salt Reactors are a kin to a giant battery that can absorb immense heat energy, and can later be converted into steam power (as most all nuclear is often a form of steam power). But this intermediary step of Molten Salt makes it much safer and easier to control. SMR"s are great for a vast variety of purposes. Small towns, spaceports, large cities, mining operations, nuclear aircraft carriers.... all sorts. The real benefit to SMR's is that if they are produced in a factory setting like an iPhone, can get better and better as they keep making more of them. This is the beautiful idea of having manufactured SMR"s. Now using SMR's WITH MSR's is a great way to cover the baseload demand (say highest demand during winter) AND the highest demand during summer. This can be used alongside other traditional power plants, as well as wind and solar too. It is not perfect but it is much better than what do today.

[@eriklondon2946]

These can and will be used for general purpose, but also for AI (which Cloud GPU's currently use about 10x as much power as a traditional cloud CPU's do), Bitcoin, Electric Cars, moon bases, electrifying +50% more of the world that doesn't have the option to be and other purposes.

That's some amazing engineering work. Love it. I am curious though as to how the Helium cooling works in practice. Yes: Helium has a very low cross-section and 3He and 4He are the most stable isotopes of that family.... The only problem with it is that it has very a low cooling capacity until you compress it to near fluid state which requires quite a compressor system... and you need a lot of helium. What happens if the compressor system fails?

[@Cycyryable]

Quite curious about the cooling capabilities of Helium. Just googled some stuff and it has a heat capacity of 5kJ/(Kg*Kelvin). So if you want to transfer 1MW of power per second, at ~10K temperature difference, you'll need to pump 20Kg Helium per second. Are they using liquid or gaseous helium?

How would you provide adequate security for each of these such that it cant be stolen or attacked in a way that causes deliberate meltdown? With distribution of generation comes lower control, which I dont see as being an option.

[@dohc22h]

Are there safeguards just in case of Sabotage, Earthquakes etc? What if the reactor suddenly broke apart and exposed the fuel? What would be done? Would an ordinary person without nuclear expertise be able to 'shut things down' in case of an emergency? Has safety redundancy been included in the design? Is there a material when in contact with outside air that would create some sort of an oxidation layer that would seal any radiation from escaping? For example covering the outside of the fuel cell with this material. I think this idea of portable nuke is absolutely amazing. Good Work.
