AFAIK coal power plants often(always? Idk) use steam to drive their turbines in order to generate electricity. I'm not arguing against nuclear, but for a very diverse mix. Warm dry summer -> solar. Rainy dark winter -> hydro & wind. If we keep burning fossils, including nuclear, until we can switch to 100% renewals, I'm okay with that. The big advantage of renewals is the comparatively low cost of phases where no electricity is produced. A solar farm doesn't generate cost at night. Coal and nuclear plants can't just be "switched on and off" at will, and if they don't produce, still need a lot more attention. But for the meantime, they are necessary, until we either overbuilt so much renewables to cover for "no wind/sun/rain" situations, or get some storage solutions (batteries, hydrogen, biofuels,...) Implement on a large enough scale.
That steam is closed circuit though. But yes, they need cooling water and perhaps pollution cleaning water. So I guess they are affected by droughts as well.
