Thermal energy storage system connected to both a nuclear reactor and a power generator

A system, comprising:

• a sodium cooled fast spectrum nuclear reactor, the nuclear reactor comprising a reactor vessel and a sodium to salt plate heat exchanger within the reactor vessel, the nuclear reactor on a nuclear site and having a first nameplate capacity;
• a nuclear site boundary surrounding the nuclear reactor, the nuclear site boundary defined by one or more barriers inhibiting access to the nuclear site;
• a thermal energy storage system located outside the nuclear site boundary, the thermal energy storage system in thermal communication with the nuclear reactor and comprising a salt working fluid;
• a fluid loop extending between the thermal energy storage system and the sodium to salt plate heat exchanger within the reactor vessel, the fluid loop configured to carry the salt working fluid;
• and
• a power generator in thermal communication with the thermal energy storage system, the power generator situated outside the nuclear site boundary and having a second nameplate capacity, the second nameplate capacity greater than the first nameplate capacity of the nuclear reactor.
