A small nuclear reactor like a battery that economically supplies carbon-free electricity to about 20,000 households for 40 years
Safety
Lead-Bismuth cooled submarine reactors had 80 reactor-years of successful experience. Eight (8) submarines proved that stable lead-bismuth coolant properties was secret for the premium safety. Early problems with corrosion, polonium-leakage and solidification are all solved by recent R&D.
