Recycled heat as a direct byproduct of generating nuclear power is in the experimental stages for supplying thermodynamics in Russia.

In contrast to business and home heat pumps...

"The experiment with nuclear heating hardly makes Russia a crusader on climate change. One of the world’s heaviest polluters, it has adopted contradictory stances on global warming, of which Pevek itself is an example:

At the same time it is switching its heating to nuclear power, rather than coal, it is benefiting from climate change in the Arctic, reviving as a port as shipping lanes become more navigable"...

"Russia is first, but hardly an outlier, in developing small civilian reactors.

This month, President Emmanuel Macron of France proposed an expansion of his country’s extensive nuclear sector with small reactors as part of the solution to climate change. "
China is building small floating reactors modeled on the Russian design."

One of the more innovative energy recycling solution ideas I've come across recently, worthy of the read.
