Agreed; and it will become more of a problem as water becomes less predictable. Problem is, for most atomic generators, that also holds true.
Investment in research is definitely needed, but building existing systems isn’t going to solve the issues either.
Thorium Salt reactors can recycle their water source and also use water from waste treatment or even sea water as they’re not high pressure water reactors.
When you don’t need the result of power generation to be fissionable material for warheads there are a lot more options available to you, such as using the waste from older reactors to generate energy and output much less reactive material.
Nuclear missiles are an albatross around the neck of nuclear power.
