Isn't the electricity /used/ to do the desalination?

Actually no.

the waste heat does that.

Boil some seawater, channel the steam through a condenser (cooled by
more seawater) and voilÃ*! - fresh water

You would probably build it just for that, since steam is what comes out
of a PWR.

I havn't seen any sums for that. IIRC reverse osmosis is remarkably
low-energy and low capital cost compared to distillation.
