> nuclear power plants also produce a lot of heat, which can be used for district heating purposes Is that the case though? To my knowledge nuclear reactor heat is only used to produce electricity and kill biodiversity in rivers so far. Also, nuclear reactors are built far away from populous area for obvious security concerns. Are there adequate mechanisms for transporting heat over long distances? That's already a problem for electricity, which incurs huge losses (heat dissipation).

>"Also, nuclear reactors are built far away from populous area for obvious security concerns" Really? Look at Pickering nuclear power station for example. Highly populated area all around it.

  By French safety standards, that's pretty crazy stuff. Leaks and other middle-seriousness incidents are rather common around nuclear sites. Why people would build it in the first place is a risky tradeoff, but why they would place it in a highly-populated area is outright madness. In any case, in that model, heating housing using nuclear sites heat makes perfect sense.

Your response seems a little cynical, but here's an example: https://www.world-nuclear-news.org/Articles/Haiyang-begins-commercial-scale-district-heat-supp https://www.world-nuclear-news.org/Articles/Haiyang-begins-c... For net heating climates, my understanding is that this form of heating can be much more efficient than alternatives like electric heating.

  That's an interesting project, but it's a little short on technical details. It mentions heating capabilities without a 100km radius but nothing about thermal losses on the way and how that model compares to municipal heating as is usual with waste burning (not saying burning trash is a better idea than nuclear fission, just listing options here). > my understanding is that this form of heating can be much more efficient than alternatives like electric heating. It makes sense that mutualizing efforts to produce heat is gonna have a better yield/efficiency. I'm just sure nuclear energy is a disaster (at least all known and planned implementations so far) and i'm not sure whether using that excess heat in this manner is efficient. I'm very sure, though, that it's considerably better than rejecting very hot water into natural streams where it destroys ecosystems.
