          Proliferation. Nuclear waste. Long term storage of said waste. Dependence on raw materials that are only available in a few places. Lack of economic viability. Lack of clear timelines for development of new technologies. Monopolistic practices of proprietors. To name just the most important ones. Oh, and the old blowy uppy thing, of course.

      It was a bad call to stop, but now it’s an equally or worse call to start again.

      Renewables win on essentially every measure and get better every day while nuclear gets worse every day.

    Run low on water, stop reaction. Fission products keep getting hot even though reaction stopped. Not enough water to cool them off. Shit.

      That’s why you have a closed water system and multiple failsaves.

      thankfully modern ones like molten salt reactors have passive safety, where they stop the reaction if overheating occurs.
      edit: My mistake, there’s no active commercial molten salt reactors.
      But nuclear power is very safe nowadays because of the multiple fail-safes, which some can still be passive like emergency cooling.
      I much rather get electricity from magic rocks than destroying rain forest in developing countries drilling oil, gas or mining coal.
      The biggest risk in nuclear is environmental disasters like in Fukushima’s case, which is the last significant nuclear incident in past 13 years

            2 MW. Fantastic. And only 8 years until it reaches continuous operation. How long will it be before that is anywhere near utility scale?

        Ah yes, the passive safety of the molten salt spontaneously catching on fire when in contact with air and can’t be put out with water.

        You can’t stop decay heat. It’s just molton salt reactors can operate at much higher temperatures and if it loses active cooling passive cooling with just air and infrared radiation while the salt passively circulates could be enough.

        Isn’t molten salt just energy storage? Heat up salt when you have excess of energy, take heat out when you need it. The worst disaster there is just the container melting.

          No, there are molten salt thermal batteries, but they aren’t the same as molten salt nuclear reactor. In a nuclear reactor the fissile material is dissolved in the salt for some reason, and the molten salt acts as a moderator or something. Apparently its safe because if the reactor power fails, the salt ‘freezes’ which prevents fission from occurring. Seems like complex extra steps to me but what do I know.

            “Can’t have a meltdown when you’ve already melted the fuel” is pretty much the whole idea there.

            MSRs have negative temperature reactivity coefficient and outlet temps around 700C at atm pressure. PWR is at measly 300C and 150 Bar.

            If all control is lost, the salt expands as it heats up pushing the expanded volume out from the reactor core. The fission stops once the fuel is leaves the core region where the moderator is. Reverse is also true: you pull heat off from the loop, so the fuel-salt becomes denser, increasing reactivity. MSRs can naturally “follow” the load, if done right.

    use lava to boil water

    use steam to turn a generator
