SMRs likewise require generators and cooling plant, 2 or 3 times as much cooling as electricity produced, perhaps even more if its to be done most economically. So if CHP is justification for such release of heat into cool environments - they should be categorized as mainly a source of heating, not high value electrical energy. An ability to make continuous heat on this planet is not a futuristic energy supply in its own right, it falls well short of the "game changer" goal.
