    Abstract: A nuclear reactor fuel integrity monitor includes: a γ-ray detector which detects γ-ray of a specific radionuclide of a subject measurement medium of a nuclear reactor; a sample container which retains the subject measurement medium therein and surrounds the circumference of the γ-ray detector; and a measurement control device which performs a control so that a predetermined amount of the subject measurement medium is introduced into the sample container and calculates a concentration of the specific radionuclide from γ-ray data per each unit time detected by the γ-ray detector and a volume of the subject measurement medium introduced into the sample container.

    Abstract: An object is to reduce radiation exposure in a nuclear plant. A nuclear plant 1 is a nuclear power generating plant where steam is generated by thermal energy generated by nuclear fission of a nuclear fuel 2C in a nuclear reactor 2, and a turbine 8 is driven by the steam to generate heat by a power generator 10. After a nuclear plant 1 is newly constructed, when a primary cooling system of the nuclear reactor 2 raises the temperature to around a power operation temperature for the first time, zinc is injected into a primary coolant C1 present in the primary cooling system by a zinc injector 20.
