> edit: Obviously the electricity produced by the nuclear plants is used in district heating to power heat pumps but that is very inefficient (already ~60% loss just from heat -> electricity at the nuclear plant). Well, heat pumps are pretty efficient, with a COP of ~3(?), the overall efficiency is better with heat pumps. Even better, however, is by combining both with cogeneration producing both electricity and heat for district heating. District heating in cities use the waste heat from the plant, and electricity can be used to run heat pumps outside the cities where the district heating grids don't reach. Of course the problem with cogeneration is that we have to get away from burning stuff, and siting nuclear plants in cities has its own challenges as well.
