Commercial fast breeder

A sodium-cooled fast reactor at Beloyarsk runs at grid scale for decades.

The 600 MW BN-600 entered service in 1980 and its successor BN-800 in 2016. Fast reactors can use nearly all the energy in uranium instead of under 1%, though France's Superphenix and others closed for cost and politics.
