[@VestedUTuber]

Actually, that would be a downgrade in this case, depending on what nuclear tech is actually being used for the train. Obviously you wouldn't want a light water reactor rolling around but a couple decently sized RTGs (radioisotope thermo-electric generators, which are powered by the natural decay of radioisotopes) running on plutonium would actually be better as they don't have the downside of requiring catenary and don't introduce the potential risks a design with an active reactor does. EDIT: Ok, watching more of the video, this is using a molten salt FBR. Those fail safe, as they need to constantly cycle their fuel solution to sustain a reaction. So even the reactor-based version wouldn't have many issues.

[@marcogenovesi8570]

@@VestedUTuber RTGs don't have anywhere near the power density to beat even diesel engines. Lasting decades does not help if it's too weak to power the train anyway. It's called atomic train for a reason, to get the power density required it has to be a full reactor, and a pretty ridiculously light and complex one at that.

That is a nice computer model of the X-12. I made an HO scale non-powered one in Union Pacific livery that I was able to push around with a pair of powered F units. (The Union Pacific was definitely interested in a nuclear locomotive to replace it's Big Boy and Challenger steam locomotives. They were already building large gas turbine powered locomotives, and later large diesel locomotives.) It looked quite impressive and had massive overhang on the curves of my small layout. A couple of other things I learned in my research on building the model: * The machinery ahead of the hexagonal reaction section is a steam generator. The passenger coaches of the time used steam from the steam locomotive for heating and cooling. When they were replaced by diesels, the diesels had to have a steam generator installed to heat and cool the coaches, usually in the tail end of the diesel. Since this engine wasn't intended to pull passenger trains, a steam generator was really unnecessary. Ahead of it was a small auxiliary diesel engine and generator; it was used to provide power to start the reactor as well as to move the locomotive alone around the train yard without starting up the reactor. The Union Pacific gas turbine locomotives also had auxiliary diesel generators for the same purposes. * The fuel used in the reactor was weapons grade uranium mixed with sulfuric acid! Refueling the locomotive would be more than just draining the old mixture out and pouring the new mixture in, the old fuel would have to be recycled. The engineer in charge of designing the locomotive helpfully proposed that the government would build the refueling stations for the railroads; but this, coupled with the initial cost of the locomotive, the cost of the fuel, the training needed for locomotive crews, and the danger of an onboard reactor, and it is not surprising it was never built. I put together a video on the X-12 on my channel as well, but nothing this nice. Well done.

I think the cost of the train is the least of their worries, we’e talking about a nuclear train. On standard gauge track a train like this isn’t big enough to sustain a nuclear reactor’s radiation.

And i imagine they didn’t have the budget nor space atm to develop it. Besides unless the train was as large as the Breitspurbahn, direct exposure to that radiaiton from the train crew could be lethal.

But there's no point really, nothing needs that much power "from a single outlet" (I mean for trains the two-three smaller diesels are more economically viable than a huge atomic, as there are not many logistical routes that require transfer of extreme number of resources between two fixed points), it's excessive and inefficient. Hydrocarbons are very effective at storing power, actually, and they're scalable from tiny to huge generators that can power districts that can be well distributed ad-hoc or with an existing grid.

But why would you bother? It would be simpler, cheaper, safer, and much more flexible to build a stationary nuclear power plant and run electric trains with overhead wires. That would *also* give you the ability to travel indefinitely without refueling (not an issue with modern trains anyway), wouldn't generate emissions, and can have an essentially arbitrary amount of horsepower. Unlike a nuclear train, the technology to do that safely already exists, wouldn't risk a nuclear disaster in the event of a derailment (or just a fuckup by an overworked reactor tech who hasn't slept in 3 days), and wouldn't require the construction of hundreds of miniaturized nuclear reactors to stuff into locomotives. They also have the advantage of flexibility; both the trains and the nuclear plant would be connected to the grid. When the trains aren't moving, the plant would provide power to the grid, and when the plant is down for maintenance, the grid could supply power for the trains. Onboard nuclear reactors only make sense when you need extremely long range operation and can't feasibly connect the vehicle to the power grid.

[@skunkjobb]

About the size of the cooler: If the mechanical efficiency would be the same as for a diesel engine, one could expect the cooler to have the same size for the same power of the engine, the same amount of heat has to be dissipated. But that's not the case. In order to get good efficiency, a nuclear reactor needs lower temperature of the cooling water than that for a diesel engine. While a diesel is happy with 70 °C return temperature to the engine (maybe a small part of the total at lower temp if it has a water cooled intercooler), a reactor prefers 30-40 °C return temperature to the condenser. Higher temp leads to loss of efficiency and loss of mechanical power. Lower temp requires a larger cooler.

[@Vincent_Sullivan]

Hey Skunk; I agree that if both Diesel and Nuclear locomotives have the same mechanical efficiency then they would have to reject the same amount of waste heat for a given level of mechanical power output. The difference that makes the condenser for the Nuclear locomotive so much larger compared to the radiator for a Diesel locomotive is that in the Diesel much of the waste heat (a quick Google search seems to indicate 50%+) is rejected via the exhaust gasses and another chunk (maybe 5-10%) is rejected through the oil cooler. (Many Diesel engines have oil sprays that cool the underside of the piston heads.) Some heat will also be rejected directly from the engine block to the ambient air. In contrast, essentially 100% of the heat rejected from a Nuclear locomotive is rejected via the exhaust steam from the power turbine being condensed back to water in the condenser. Two more factors increase the size of the condenser for Nuclear locomotive. First, the spent steam enters the condenser in the gaseous state and gasses have very low thermal conductivity compared to liquids such as the coolant in a Diesel locomotive. This slows down the heat transfer a lot, thus requiring a larger condenser. Second, the Nuclear locomotive condenser is being cooled by ambient air at perhaps a design maximum of 40 degrees C. and the condensed water output is just below 100 degrees C. so the delta T is only 60 degrees C. In a diesel locomotive the cooling system will probably be under pressure to increase the boiling temperature of the coolant. Many older Diesel locomotives run plain water (with corrosion inhibitors) as coolant but more modern ones use a mixture of water and ethylene glycol. A 50/50 mixture of ethylene glycol and water pressurized to 15 PSI boils at over 131 degrees C. so the system can be run with delta T of about 90 degrees C. compared to 60 degrees C. for the Nuclear locomotive. This will make the Diesel locomotive radiator much more effective for a given size. Full disclosure... I am an electronic engineer, not a thermodynamicist. If there is a thermodynamics expert in the crowd please chime in to let me know if I am on the correct track or not...

[@williamzk9083]

A dieselo reject half its heat through the radiator and half through the exhaust. A steam engine must reject all of its heat through the radiator. The only way around this is to increase operating temperature so a smaller radiator is needed. Best done with CO2 or Helium rather than water.

The funny thing is, there was actually a TV series that was based on a nuclear powered train. "Supertrain" rain on NVC in the US in 1979, and it was set on a nuclear powered train dressed out like a cruise ship. Complete with a swimming pool shopping mall, and of course a disco since it was 1979. Similar to "The Love Boat", it was a weekly series. And the train would go from New York to LA in a day and a half.

[@aurorajones8481]

This is ironic because when steam locomotives first came on the scene they were equivalent to a nuclear reactor in complexity, very few knew how to operate them, they were very dangerous if you didn't do it right, hell they could explode just like a reactor. So... yea putting this on a train is just a chefs kiss in that vien.

[@VestedUTuber]

On top of that, these would be steam turbines with electric transmissions. So you've got an active nuclear reactor (or a huge-ass RTG, but that's cheating in this context), high pressure steam, a steam turbine (gotta watch your revs) and high voltage high current electricity.

[@CrossWindsPat]

While I am a massive fan of nuclear power and would love to see more of it, your analogy falls apart when you account for nuclear fallout. That is not something that can simply be overcome with training and tech IMO. Having that mobile and near mass amounts of people is not a good idea...

[@pootispiker2866]

Besides solving a problem that doesn't exist, the first problem I can think of his horrifically slow power response times. First you have to hear the reactor, then the water, make steam, then turn a turbine up to speed. Thank god this never happened.

Well I propose a better Idea for nuclear train how about we put those reactor stationary so that the reactor can be bigger, more efficient, safer to operate, easier to maintaining both reactor and train. Then for all of those hassle for having special yard, we can use those money to research and build special magic transfer power device. So we can operate multiple train at once with single reactor.

One other problem is that if your hauling a long train like in real life you’ll see there are usually helper engines in the middle or rear to add extra power and to help reduce string-lining, and I’m pretty sure maintenances aren’t going to be easy

[@jamesowen4938]

It would be easier to build a nuclear power plant and use electric locomotives. They could sell the extra power to the public. It would improve the power grid, speed up schedules and running time, and lower the transportation costs for bulk foodstuffs like grain and flour. And that's simply because electric locomotives can out pull any diesel or steam locos, and run faster with heavier trains.

[@hanzzel6086]

Iirc, three nations built them. The U.S and (the only one to build multiple) USSR (obviously) and one other that I can't recall atm. They had the problems of high operating costs, limited "friendly" ports, and (most importantly) most entered service at about the same time as the Chernobyl Disaster, which made finding people willing to sail/transport cargo on them difficult (and greatly worsened the second problem). The USSR ones (which were ferry/cargo/icebreaker combos) lasted longest because they solely operated in Russian waters hauling cargo and passengers to/around largely isolated communities.

[@a.p.2356]

It has been done. They has serious issues with logistics and operating costs (turns out bunker fuel is REALLY cheap), and could only dock at a handful of ports around the world for political reasons. Russia actually still has a handful of nuclear powered civilian ships in the form of nuclear ice breakers.

Technically, all Nuclear-Powered energy sources are basically steam engines. As I was learning about the largest Steam-Powered Locomotive Engine, called 'Big-Boy', I thought to myself, “why are we not using nuclear power in our trains today?” With today's Small Modular Nuclear Power, it makes sense to me, to use it in not only trains, but in most power generators. Are we waiting for batteries to get more efficient? Or is there a group of people, or lobbyists, who are just getting in the way of a better power source?

[@CrossWindsPat]

@@crackedemerald4930 Bingo. They have literally spent billions smearing green energy across the board. The mass paranoia behind nuclear energy is no accident....

[@broski8849]

For trains it wouldn't make sense at all, since you could always just use overhead lines for electricity, which could theoretically come from any power source, like a nuclear power plant. Funnily enough however, the reason why most railways on the American continents are still unelectrified is very likely lobbying

[@MarceloBenoit-trenes]

@@broski8849 no. They dont want to electrify because it is expensive. However, tests were done in 1973 to 79 to do that. Also, there was a transcontinental line which had two electrified sections and it was taken down because of stupid management. I am talking about the Milwaukee Road.

[@rya1701]

Not all. There are RTG (Radioisotope Thermoelectric Generator) that can turn the heat from fission directly to electricity. It's used on old space probes that doesn't need a lot of power, need to last a long long time and can't have solar panel

With Los Angeles being a big train place with a massive population, could you imagine one of these miles long trains becoming a runaway on Cajon Pass and derailing in the basin while going over 100 mph like what has happened before, but instead of being a diesel train carrying inert cargo, like what has happened in the past, it was using these light water nuclear reactors and was hauling a bunch of LNG tanker cars and other hazardous and toxic cargo? We probably should be looking at something more like LFTR in stationary reactors. LFTR reactors use molten fluoride salts, so chemically inert. Water leads light water reactors to be inherently unsafe, which is a bit of a complex topic to briefly explain why and how to mitigate risk and sodium is highly reactive, and so not something you want to have rolling down the tracks. Even something as mass efficient as LFTR while having some better inherent safety is still not something you want rolling down the railway as an active reactor powering the train. You still want this to be stationary. One concept I have come up with is a hybrid train where you put up overhead electric where it makes the most sense, and really with LFTR making electric power cheap, have it everywhere. But even if you don't have it everywhere, you could do battery electric with LFP batteries especially as iron is plentiful and places like the Salton Sea are jammed packed with lithium, so the key ingredients for LFP batteries are extremely plentiful, and then use natural gas to run a gas turbine locomotive. The idea being the battery electric and gas turbine locomotives share power and if the batteries get low and there is no overhead power, the gas turbine locomotive could generate lots of power to distribute to the battery electric locomotives. Trains already haul around LNG tanker cars, so just rig one up to the gas turbine locomotive and it will have plenty of fuel.

In my opinion, in the mid and long term, the use of nuclear-powered machines in civilian applications may face restrictions due to concerns about safeguarding the technology. The risk of theft or misuse by rival nations such as China or Iran, or terrorist groups, poses significant security challenges. Furthermore, the use of nuclear-powered cars, airplanes, cellphones, and batteries raises concerns about potential health risks due to radiation exposure.

It’s literally pointless though. It’s more expensive, more dangerous, needs more infrastructure and there isn’t a reason for it.

@@tusharsaikhedkar9808 You miss the point. Creating a reailway network with powerlines or even just outfitting existing railway networks with powerlines is extremely costly. So much so, that railway companies rather use diesel locomotives. His point specifically is, that small nuclear reactor technoligies, wich are currently in the trial phase,would make a more appealing business case, as the reactor needs much less maintanance and control from a skilled worker. The thing is, with the current advancements in small modular reactor technology and the more and more expensive to maintain powerlains, the scenario of a nuclear train will be unavoidable.
