        Also because material science hasn't cracked the brittleness problem at commercial scale without just replacing all the tubing every couple years which obviously doesn't make sense. There are several private companies and nation states trying to solve this problem at this very second.

            There's a lot of new smaller reactor gen III+ designs that are interesting and hopefully able to be commercialized as well as some distant gen IV stuff, but everything is decades out from commercialization (LFTR among those). The nut will be cracked I'm positive, but it will be too little too late for our current climate predicament (same with fusion or other exotic generation tech).

              so gas cooled, etc might be viable before everything goes to shit? what about more efficient heat to electricity conversion..like using MHD turbines? or is that too far out too?

                I didn't really dig deep into alternative generators so I'm not sure where the commercialization process of that is (though it's pretty cool). Most of my nuke knowledge is from some really in depth state of the industry reports I worked on and is fairly domain specific and linked to it's viability as a climate change friendly source of generation.

    Nuclear power is the best but those cooling towers are cringe. In the USSR nuclear power plants were connected to a network of pipes that gave free, unmetered heating to the entire city. This was usually pointed out in the west as symptom of the wastefulness of the planned economy because people would rather open the window than turn down the heat.

    Meanwhile in the west they throw away all the waste heat in those massive cooling towers, or they dump it into the sea at such rate that when the pump breaks like in Fukushima the power plant blows up.

    The real reason we don't use nuclear power is that it takes about six years to make a nuclear power plant, during which time the project is racking up debt from its mortgage, which it can't start paying down until the plant becomes operable. Plants don't start returning an actual profit until about ten years in, after they've paid off their mortgage and interest. A gas power plant could've already started paying for another gas power plant in that time. Not to mention that this ten year time frame is longer than the career of most corporate boards.

    Nuclear is good. I used to be against it. I get the reasons why. But the reality is we have a very limited amount of time to get to zero carbon emissions. Solar and wind are great but they can't handle the global energy by themselves yet, even if you assume massive reductions in energy consumption. Nuclear is the bridge technology, and hopefully in like 40-50 years we can shutter every nuclear plant. But until then...

      I would argue it's the other way around. Nuclear plants take a long ass time to plan, let alone build. Using solar and wind as a bridge to building worker controller nuclear plants is my thesis.

          capitalist nations outsource a lot of the planning and production of nuclear projects, needlessly complicating it in favour of profit

            But they don't produce enough energy and are incredibly resource intensive for the energy they generate. There's not enough raw minerals to generate renewable electric for the globe right now with current tech

              That's why it's a bridge to nuclear. All the nuclear tech in this thread is being talked about as if it's real but it's mostly theory and testing will increasing the time frame.

              Like, there are wind farms and solar farms being built right now. Nuclear plants aren't.

              There's quite a few papers and reviews of papers that talk about the time frame issues with nuclear. What people in this thread don't understand is that most of what you are repeating is lobbying material.

                Wind and solar is being built because there's massive subsidies right now and very little for nuke. Solar panels are easy to commodify. Nuke power plants are more difficult

                They don't produce enough for the entire world my friend. Wind still only amounts to less than 5% of power generation globally. And what do you do when the wind is blowing and it's night out? You either need massive battery installations or baseline power from nukes

                  They don’t produce enough for the entire world my friend.

                  not at the moment, true

                  Wind still only amounts to less than 5% of power generation globally.

                  True and even at just 5% it is profitable without subsidies in many places!!

                  And what do you do when the wind is blowing and it’s night out?

                  Wind blows at night and on a whole continent there is wind pretty much somewhere at all times, also at night power usage is a lot lower and also there are pretty clever solutions for this, not just one solution but a multitude of different things that can be done and already are done.

                  You either need massive battery installations or baseline power from nukes

                  The nukes that already exist should be kept until every carbon plant is shut down, so they'll stay with us for a while anyways and yeah, some battery installations already exist and lots of stuff is being developed.

          Modern cycled natural gas plants output the almost exactly the same lifetime co2 as nuclear plants when you account for construction, decommissioning, and dismantling because of the huge amount of concrete these plants require. Though to be fair, this does ignore methane leaks from gas wells, so you win some and you lose some I guess.

        Deaths related to nuclear compared to wind are significantly lower despite the terrible ways in which the former has failed. Workers falling or being injured on the job causes significantly more death, it just goes unreported compared to the spectacular nature of a nuclear failure.

        That and the fact modern design is basically foolproof except where ignorant people cut corners to save money (as occurred at Fukishima which was designed to withstand exactly what occurred but cutbacks on safety in the design for cost saving occurred). I think that if the plants are built by non-capitalists nuclear they should operate perfectly fine now.

          Chernobyl and Fukushima created exclusion zones in the thousands of square kilometers that displaced hundreds of thousands of people. Building them in the middle of nowhere isn't an option either, these plants require access to large amounts of fresh water, and such zones tend to be highly populated. Tbh I don't understand how anyone can look at the effects of the previous nuclear catastrophes and conclude that it is a good idea to continue building more.

            The reason you can only name those two disasters is because nuclear disasters are so rare when you account for how much energy is produced, and modern reactors are even safer to the point where they're as safe as renewables, look at the data, idk what else to tell you. Logically you should be hundreds of times more scared of fossil fuels.

              Fossils are not the alternative to nuclear power, everybody agrees that they have to go. When you include all the costs of nuclear power, instead of ignoring them as externalities as capitalism allows them to do, it is not cost competitive with renewables such as wind and solar.

      Liquid salt reactors seem like a meme, I mean I'm no nuclear physicist or chemist, but I did look at the paper they wrote on it and a super-hot mixture of gaseous/liquid fluorine+sodium seems like the worst possible place to have a nuclear reaction.

        I'm only aware of what I've heard about from a podcast (.Net Rocks!), so I'm not trying to argue viability/feasibility. From what I remember, the whole benefit of using a liquid salt as your fissile material is to reduce (eliminate) the risk of a steam explosion, which is (citation needed) the leading cause of meltdown.

        edit: And the whole point of using Thorium is because it's more plentiful, and doesn't contribute to nuclear weapons.

    The amount of people here who think they know what they are talking about because they watched a Ted talk one time is infuriating.

    Everybody basically completely ignoring the deep deep interconnection between the military need for nuclear weapons and the nuclear industry they grew up from that.

    The problems of planning, building, maintaining, decommissioning and waste storage of a nuclear plant are absolutely huge, and they are incredibly expensive and take exceptionally long to build.

    They are not the 'one neat trick' to solving climate change held back by annoying hippies and ignorant NIMBYs a large proportion of comments here imply.

    That's not to say there is no place for current, and even some new build nuclear, But most countries and regions will have better and cheaper solutions if properly planned. Directing research to safer and simpler nuclear solutions is also good - but a very long term goal.
