SMRs like SSR heatpipes are interesting. The issues of decentralization of controlled nuclear sites are many. It's better to have many SMRs in one location for safety, security, and backbench of resources and talent for engineering and operations. Simply, it scales better. Giving every Tom, Jane, and Sally corporation or town an SMR is an absolutely terrible idea.

Oh sure, I understood the effort to make it easier to "plop down" bunch large plants at once, not hundreds of small ones - though those are kind of interesting in isolated locations.

The other thing is old Soviet idea of using small nuclear reactors for heating - put small reactor to every town and run central heating to the housing estates, meaning you get to use close to 100 % of the heat output of the reactor, instead of the ~ 30 % the turbines give you in electricity.

Of course, if things go wrong, you have very efficient radioactivity delivery mechanism to every home. And outside of very cold climates it might be actually less efficient than a modern heat pump, even accounting for the heat conversion.

For local heating, ground source heat pumps are often a good idea.

Also, solar thermal energy storage is an idea, as well as the potential of solar PV hot working fluid cogen.

Stanford's SESI is interesting, but it would be awesome if solar, wind, or fusion could take the places of fission and methane in cogen applications.
