Good!

Anti-nuclear is like anti-GMO and anti-vax: pure ignorance, and fear of that which they don't understand.

Nuclear power is the ONLY form of clean energy that can be scaled up in time to save us from the worst of climate change.

We've had the cure for climate change all along, but fear that we'd do another Chernobyl has scared us away from it.

Long term nuclear is great...

But building new plants uses a shit ton of concrete. So we're paying the carbon cost up front, and it can take years or even decades to break even.

So we can't just spam build nuke plants right now to fix everything.

30 years ago that would have worked.

(What’s with the downvotes?)

Small scale reactors that require almost no maintenance and produce enough power for a single city are the hot topic right now due to what you just mentioned. As a side product, they provide hot water for the city.

(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?

Imagine living in a snowy city where hot water is pumped through the sidewalks to people's homes. No frozen pipes, no shoveling snow. No people freezing to death...

You still need to clear snow and ice. The hot water pipes are insulated to ensure that the hot water remains hot until it goes into radiators and faucets. You'd lose all that heat if you use it to heat sidewalks.

My city does this. Hot water is pretty cheap here if you're hooked up to the municipal network. If you have an electric water heater you'll go bankrupt in the winter.

Small scale reactors are actually more expensive than larger reactors. Even compared to Vogtle 3 and 4...
