Coal and gas power stations need cooling water in exactly the same way as nuclear.
Regarding the waste, I'd much rather have the very small amount of nuclear waste produced by a nuclear power station kept somewhere nice and safe than the humongous amount of waste that coal and gas produce and spew out into our atmosphere. A coal power station releases more radioactive waste than a nuclear one. Even the renewables produce quite an impressive waste stream compared to nuclear
