Thermoelectric conversion module assembly for nuclear reactor, fuel irradiation assembly, and material irradiation assembly

摘要

PPROBLEM TO BE SOLVED: To provide a thermoelectric conversion module assembly for a nuclear reactor available as an independent power supply in the nuclear reactor without modifying a nuclear reactor coolant pressure boundary. PSOLUTION: The thermoelectric conversion module assembly for the nuclear reactor includes at least one set of thermoelectric conversion module 2 having a heat source-side electrode section 3 to be disposed on the high-temperature heat source side and a heat dissipation-side electrode section 4 to be disposed on the low-temperature heat source side having a lower temperature than the high-temperature heat source; a gamma-ray heating element to be disposed on the part of the heat source-side electrode section 3 of the thermoelectric conversion module 2 and generating the heat by gamma rays in the nuclear reactor; and an airtight container 7 housing the thermoelectric conversion module 2 and the gamma-ray heating element, sealed and depressurized or vacuumed, and provided with an externally exposed electrode 9 having conduction with each of the electrode sections 3 and 4 of the thermoelectric conversion module 2; wherein one side of the airtight container 7, or a case lid 7b, is pressed against the heat dissipation-side electrode section 4 of the thermoelectric conversion module 2 by a pressurizing force acting on the airtight container 7, and the power is generated based on a temperature difference between the nuclear reactor coolant flowing around the airtight container 7 and the gamma-ray heating element generating the heat by the gamma rays in the nuclear reactor.
