Sable Fast Reactor

Sable Fast Reactor, Series B

Preferred equity in a sodium fast reactor with integrated salt storage, siting where a coal plant already has the transmission.

A fast spectrum needs no moderator, and sodium at atmospheric pressure removes the high-pressure containment problem. Bolting a molten salt heat store onto the secondary side turns a baseload machine into one that can follow load and sell into peak pricing. Siting at a retiring coal plant inherits the switchyard, the transmission rights and the workforce.
