Manhattan is an island. It's surrounded by cooling fluid. > Sometimes people don't want heating, but you still need to cool down the plant. You can turn it down or off. > Remind me why power lines aren't an option? It's more economical not to waste half the plant's power output. 1 GW of heat comes out the reactor, 50% becomes electricity (with heat pumps you can make that 2x heating) and 50% is low-grade heat sufficient for space heating. You get 1/3 more heating for the same cost.
