[@Shalashalska]

One other significant factor for nuclear trains: You could instead build a nuclear power plant, and run electrical cables along the track, to make an electric train, which gets functionally the same performance, but without the locomotive carrying an extra 200-300 tons of reactor, which means you can get 200-300 tons of cargo. The reason nuclear power for ships is effective is because ships are very efficient at carrying huge amounts of weight in addition to the nuclear waste being less of a concern in remote parts of the ocean.

[@dianapennepacker6854]

Nuclear power with a closed loop for large vessles would be nice. As long as they were the type that entombed themselves during a melt down. I seen an SMR that had this feature. We already have electified trains in many places. So I agree with you that is a better method then having a thousand SMRs in trains on a daily basis. Trains in the future? Fast charging batteries at stops could do it within 20 years. The amount of energy you could get back in certain places through regenerative breaking is immense by picking up heavier loads at the top of hills. Using fast charging batteries/capcitors at certain places on top of that. There is an electric dump truck called the E Dump. Pure EV, and never has to recharge due to receiving heavier loads at the top of a hill, and then it uses regen breaking to charge 100% by going down it. Then uses that energy stored in the batteries to go up the hill. I am not saying that is what will happen. Only that it is possible in certain routes.

[@nolananderson4782]

Exactly. One other thing that makes nuclear naval vessels more viable than trains is that ships don't travel along defined paths. Anywhere there's ocean, they can go, so running a cable isn't feasible. Meanwhile, with trains, you already need rails, so just adding cables is a relatively simple process.

[@genkibob]

So basically, France.

[@notmenotme614]

Another reason why nuclear reactors work so well on ships is because it’s must harder to crash a ship that’s travelling at only 20 mph and literally 100s of miles away from the nearest object.

Yup, nuclear powered supertankers and cargo ships makes much more sense, also given that there's no electric grid in the ocean.

Nuclear trains, I say; nuclear trains, you say. My friend’s house, until he was 18, was next to a railway station. Crumpsall is now a station on the Manchester Metrolink tram network. Three or four times a week, a train carrying nuclear waste would meander up the line heading toward Windscale, now Sellafield, starting from the nuclear power stations in Kent, Wales, and elsewhere. On a few occasions, they broke down and crawled into the station-the entire lot of them. The police would look worried until they saw the Chinese takeaway a few minutes away. Then the train would be abandoned, and they would order a 20-person banquet: chicken balls, beef and chicken fried rice, and, for the unadventurous, half rice, half chips, and curry. At no point were any containers tampered with. A freezing cold and drizzly night at the beginning of January in North Manchester obviously was not at the top of the KGB’s list of priorities.

It is a shame that nuclear enery got such a bad name. I suspect that it is mainly due to the fossil fuel lobby that didn;t want fossil fuel to end.

[@matwyder4187]

As events of the last few years clearly show, KGB agents are by far not among our brightest, but even considering those miserable standards, I'd still wonder what on Earth could have they planned with some heavily shielded containers of nuclear waste and why. Even in an actual war it would be rather stupid thing to tamper with. Can't even blow it up efficiently to make a dirty bomb. Like, if you leave it unattended for weeks, then sure, someone will eventually appear with proper tooling and take it, because it has some value on the black market, and who wouldn't risk dying in radiation sickness for a few grand, but it's still a massive effort, not something to be expected to happen in a few hours.

[@L33tSkE3t]

Trains have this issue of sometimes derailing, so it would probably make more sense to have the nuclear power station in a fixed location and have it feed energy into the grid to run the train and anything else that might need power. Which is how things work and if we can switch to renewable reactors here in the U.S. like what is used in Japan and Europe, where spent fuel can be re-enriched to be used again. This drastically cutting down on the amount on nuclear waste created that then needs to be stored for long periods of times and even reduces the length of time that waste needs to be stored by utilizing radioactive isotopes with much shorter half-lives. I know people get uncomfortable when discussing nuclear energy due to things like Chernobyl but, the RBMK reactor #4 at the Chernobyl site was inherently dangerous by design, as it was not a pressurized water reactor with a traditional containment vessel. Compared to say, Three Mile Island, the nuclear meltdown was contained, where Chernobyl very much was not) and the the secondary nuclear reactor on the island ran without issue, pumping electricity into the grid for decades after and only just recently was decommissioned in 2021. Nuclear fission in the only carbon free high energy density source of power we have access to today and is going to be essential to moving towards a carbon free energy future. So to completely write off nuclear fission is really foolish, especially with the number of advancements that have been made to make it extremely safe.

The Soviet K-429 sank *twice*, but was raised after both sinkings and put back into service, before being eventually scrapped. And the Russian K-141 Kursk was salvaged after sinking and scrapped. Those are probably the other two that were counted.

[@ihak707]

funnily enough, coal contains trace amounts of radioactive elements. Considering the amount of coal being burnt at coal powerplants this means coal power plants releases a relatively large amount of radioactive waste through their smoke. This is why costs of building a nuclear powerplant can't be reduced by converting a coal powerplant into nuclear, because the ground around the area has too much radioactivity for a nuclear powerplants safety guidelines. This compared to the amount of radioactive elements released by a nuclear powerplant (0) is a hilarious contradiction

[@rubiconnn]

You actually receive less radiation inside of a nuclear power plant than outside of it because all of the shielding is blocking the radiation on the outside from getting to you.

We monitored the stack discharge and have records of how clean the stacks are. If you want to talk about radiation, lets talk about why they can't get rid of the spent fuel because it is so highly radioactive, towns refuse to let trucks or trains run through the town. Because of this, most nuclear plants have to store the spent fuel rods on property. Most still have them in pools to keep cool because they cant get rid of them, radioactive dumps in y our town.

Babcock and Willcox is working on a microreactor that can fit into a couple of standard shipping containers.

Right now the design is aimed at replacing diesel generators for remote power generation, but I'm sure if it pans out someone will look into redesigning it to fit into a locomotive form factor.

The idea is to lower our production of green house gases in order to try and stem the evironmental damages we are doing to both the planet and its atmosphere. Bio mass such as plants and algae are great at trapping and holding C02 as long as they are alive. Once dead and starting to decompose or are burnt as fuel, that trapped CO2 and other pollutants are released into the atmosphere and environment. Hydrogen and nuclear energy are for the most part carbon neutral. Yes there is a carbon price to be paid in developing the infrastructure needed to suppot these energy sources, but the same holds true for all sources of energy production we currently use, and that includes solar and wind. There is quite an interesting debate on the actual carbon cost per kwt hour generated solar panels actually incur with their production and operations. Basically it all boils down to the Heinlien TANSTAAFL principle (Google it), everything has a cost, the only difference is something either more or less then others.

Much of what he says is true, but he's unapologetically and unscientifically biased in favor of nuclear energy, so much so that he blinds himself to its shortcomings. You're thinking of nuclear waste casks. That's not relevant to this case - in a portable nuclear reactor, it has to be active, so you couldn't just stuff it away in a cask like you can with waste, it needs to be active within the reactor. So, in the event of a crash, this unprotected nuclear vessel gets ruptured and an appalling disaster occurs.

If you can make a reactor withstand a rail crash, you can use the nuke engines to run cargo. Excess energy gets dumped into overhead lines where they exist, to assist with powering non-nuclear passenger trains. Any excess after that can run EV chargers and the general local electricity grid.

Holy shit they mounted a nuclear reactor not just in a cargo ship, not potentially in a train, or a car as Ford promoted during the 1960's.....They were actually crazy enough to mount a reactor in a B-36 and ACTUALLY FLY IT WHILE IT WAS CRITICAL!

@@cedvelt Solar has an absolutely abysmal EROI, especially when battery storage is included in the equation. The EROI for solar is so bad, that the energy used to produce the solar energy systems becomes a major concern. Right now, the vast majority of solar panels (and associated electronics, batteries, etc) are produced in China, which gets most of its energy from coal. The production of silicon also requires coal, or some other carbon-rich fuel. Ever wonder why we're not getting anywhere with regard to reducing CO2 emissions on a global scale?

I just don't really see it. Now, they could use it in a sort of dirty bomb (just strap radioactive stuff to regular bomb then blow up to spread it around), but given how many orphan sources are around, not to mention radioactive materials that can be made much more easily than stealing them from a operating reactor...Nothing is stopping them from doing something like that now.

[@damian99669]

I also think that training a railway crew to operate a nuclear reactor and maintain those qualifications on top of the plant maintenance that would have been required by the NRC would have been excessively high.

[@GarfieldRex]

Thank you both!

[@KS-PNW]

@@GarfieldRex np. The DoD is actually currently looking into transitioning away from uranium reactors (for carriers and subs) and towards thorium reactors. They function pretty much the same but the reaction is more efficient so you only get about 1.3% as much waste. Even that waste has a half life of ~300 years vs 30-45k years that plutonium/uranium waste has. The other big advantage is thorium reactors can only operate under very specific enviromental conditions that aren't met by normal air or water. So with a active system (that only works if everything is normal) any major issue causes the environment to normalize which stops the fission reaction. That way if anything goes wrong they "burn themselves out" within minutes without any risk. Even if someone could recover the reactor, thorium can't be enriched to the point where it's an effective weapon it's safer all around. Current systems have been tested exhaustively and are very safe but that would be the next step forward. Probably happens in the next decade or two.

[@scottallberry]

Cooling would be the problem. You need to cool the water you superheated into steam back to a liquid so you can superheated it again. Power plants use cooling towers (that big huge chimney with steam coming out from coal and nuclear plants) cool the water that was turned to steam. The water from the towers evaporates and drains into cooling ponds before being returned to the river. Trains don't have access to a river or cooling ponds, so some other massive means will need to be carried to cool it

[@jeremiahlyleseditor437]

This story is a good one and relevant especially since a Hydrogen car was used as a bomb overseas recently.

[@ebbrook1]

Sounds like Dr. Borst was projecting small modular nuclear reactors, which suggests that whichever of the current development crop of small modular rectors actually works on a production scale will immediately create the potential for nuclear trains, and likely nuclear cargo container ships.

[@miles8385]

Might be a useful vehicle for arctic and antarctic conditions since it could reliably provide electricity for locomotion and heating without the fuel constraints of fossil fuel powered vehicles. The naturally lower environmental temperatures would be an effective aid to cooling, and the remoteness of the locations would reduce the potential damage of any radiological accidents. Many reactor safety technologies and techniques could be adapted from submarine reactor designs, which have consistently proven safe for decades (at least the USN ones, I'm not as familiar with other nations). Come to think of it, a nuclear powered version of those giant snow-crawler vehicles in a train configuration would be better since it wouldn't need tracks, and it could be wide enough to float if it breaks through ice or melting permafrost.

If they HAD built that beast, every railbed and trainbed in the country would have had to be completely rebuilt just to handle the weight of the locomotive. Simin, when you were comparing the train reactor operation to a land based power generating station, I was thinking "Wrong comparison! A nuclear submarine would have been a much better one." Since many were/are actually electrically driven rather than a "direct drive" from the steam turbines that spin the generators. The size would have been more comparable too, at least for the early generation of nuke boats.

Boilers are maintenance intensive period. This thing will go down every year for boiler tube failures / reinstalls etc. It's the nature of this method of power generation, especially if you are swinging the load on it, that tears the hell out of boilers.

[@RCAvhstape]

One thing I was thinking also, in the event of a derailment the radiator car is likely to separate from the reactor car, and even a properly scrammed reactor needs a lot of cooling to prevent decay heat from causing a meltdown. This was a major part of the Fukushima accident: the reactors all scrammed properly and shut down, but since the backup generators were out, they couldn't keep cooling water pumps running. From an economic standpoint, you'd also need a substantially larger crew to operate one of these compared to a diesel electric. In addition to the engineer and conductor, you'd also want to have well-trained reactor operators, and maybe a health physicist, and those guys are going to demand decent salaries. You also need security and a whole infrastructure for servicing and maintaining these locomotives, as well as a lifecycle program that accounts for the disposition of the powerplant when the locomotive is at the end of service, similar to how nuclear navies deal with submarines. As others have already stated, running electric trains off a grid powered by a stationary nuclear power plant is a lot safer and easier, and is in fact how many modern electric trains operate today. So in a way, we already have "nuclear powered trains".

[@lifequest7453]

The problem at the Fukushima plant was the designer company made a bad design and instead of installing the diesel emergency Generators Above the flood plain (yes you have to consider a one in a million event like the Tsonomi) so it would not be effected should the land flood. The generators were installed at ground level where water could flood them out. These are the EMERGENCY GENERATORS that were installed at vulerable locations.... This company should have known better (and we have all heard of them)
