(What’s with the downvotes?)

Lots of people know virtually nothing about nuclear even tho they’re avid supporters of it. So when you point out a downside, they get mad.

As a side product, they provide hot water for the city.

Hot water (technically superheated steam) is the main (and only immediate) product of a nuclear reactor…

Trying to directly use secondary coolant as hot potable water just makes zero sense though. It’s waaaaay more efficient to move the electricity and then heat different water.

I mean, you’re talking about an open loop nuclear system…

No sane engineer would ever do that. A small primary loop leak and your dosing everyone, all to just essentially lose efficiency.

Where did you even see that suggested?
