Just in case you are not joking, the sewage is not exposed to radiation.

Water essentially can not become radioactive, and the sewage is used to cool water, not (directly) nuclear material. As you probably know all heat engines need a hot side (the uranium) and a cold side (the sewage) - the cold side is also those huge cooling towers you see while driving near a power plant.

I don't think that's what they were implying; heat kills pathogens too.

It's not hot enough for that, it's usually only 10 to 15 degrees above ambient.

Just hot enough to make the bacteria thrive. Juicy.

It also gives arguments to both sides, "nuclear is shit" and "nuclear is the shit"

Imagine all the pathogens that are mutated for free.

I said the same just now, before I saw yours. I know it is going to get down voted, because I didn't append the '\s' tag, and it was a little to obscure. Cheers!
