    What? I’ve grown up around people in the nuclear industry, and nothing I’ve ever learned about the function “wastes” water.

    Some rambling on how I understand water to be used by reactors

    You’ve got some amount of water in the “dirty loop” exposed to the fissile material, and in the spent fuel storage tanks. Contaminated water is stuck for that use, but that isn’t “spending” the water. The water stays contained in those systems. They don’t magically delete water volume and need to be refilled.

    Outside of that you have your clean loop, which is bog standard “use heat to make steam, steam move turbine, moving turbine make electiricity, steam cools back to water”. Again, there’s no part of that which somehow makes the water not exist, or not be usable for other purposes.


    Not saying you’re wrong. Renewables are absolutely preferable, and Texas is prime real estate to maximize their effectiveness. I’m just hung up on the “waste water building reactors” part.

    Guessing it was some sort of research about the building process maybe, that I’ve just missed?

      Building them doesn’t waste water, running them does. In a place with a lot of water they make sense but any industrial water usage in a place with limited water supplies - when there are lower usage alternatives - seems wasteful

        They literally outlined the whole process… What stage in

        Outside of that you have your clean loop, which is bog standard “use heat to make steam, steam move turbine, moving turbine make electiricity, steam cools back to water”. Again, there’s no part of that which somehow makes the water not exist, or not be usable for other purposes.

        Wastes water?

          steam cools back to water

          That one. The most common methods of condensing that steam rely on large bodies of water acting as heat sinks. Water in those large reservoirs is lost to evaporation, which is exacerbated by the additional heat.

          The water in that reservoir must be reserved for the nuclear plant; a drought that drains the reservoir will knock the plant offline.

          Air-cooled condensers are possible, but at significantly reduced efficiency, especially in already hot environments.

          If you send the water through a bunch of pipes it needs treated before it can be put back into the environment. This is true of any industrial process. This takes it out of circulation for a while, and in an arid state like Texas that’s a waste.

          And reactors need a lot of water, which is why they’re built next to the ocean or a lake or something.
