Nuclear fission doesn't work because it requires a reliable flow of cool water. As such, it warms the planet too. Rivers are often too warm to cool nuclear plants, and so the plants have to pause operations. It's neither safe nor reliable.

Mind linking to this, I've talked to several nuclear engineers who are spending their careers trying to solve problems related to nuclear energy adoption and none of them have mentioned this issue.

If you read any non-HN news at all, you would've seen it over the years:

It has happened in the US too. This aside, the Fukushima nuclear disaster is a reminder that nuclear fission is not desirable.

Interesting reads. Thanks
