Classification: CPC G  Y | IPC G

Claim 1:
2. A nuclear power plant comprising:
a molten salt reactor (MSR) to produce heat, the MSR comprising a vessel;
a heat exchanger system;
radioactivity detectors positioned outside the vessel;
shutoff mechanisms positioned outside the vessel; and
an end-use system,
the MSR comprising a graphite moderator core positioned in the vessel, and a molten salt circulating at least in the vessel, the molten salt to transfer the heat produced by the MSR to the heat exchanger system, the graphite moderator core defining one or more than one through hole, the vessel being sealed to permanently integrate the graphite core into the vessel,
the heat exchanger system having an inside portion located inside the vessel and an outside portion located outside the vessel, the inside portion comprising a plurality of heat exchangers in fluid communication with the one or more than one through hole of the graphite moderator core,
each heat exchanger having an inlet conduit and an outlet conduit, each inlet conduit and each outlet conduit extending from each respective heat exchanger, through the vessel, toward the outside portion of the heat exchanger system and connecting each respective heat exchanger to the outside portion of the heat exchanger system,
each heat exchanger having associated thereto a respective radioactivity detector, each radioactivity detector arranged to detect radioactivity present in a coolant salt circulating in the respective heat exchanger,
each shutoff mechanism arranged to shut off circulation of the coolant salt circulating in the respective heat exchanger when radioactivity beyond a threshold amount is detected, by the respective radioactivity detector, in the respective heat exchanger.
