Development of auxiliary photo supervision tube prototype (2
Irradiation supervision of reactor pressure vessel materials is the periodic monitoring of changes in strength and toughness caused by neutron irradiation of the ferrite material in the reactor core zone. The change in toughness of the ferrite material obtained by irradiation supervision will contribute to the demonstration or appropriate adjustment of the operating parameters of the nuclear power plant. The irradiation supervision tube is a device placed in the reactor pressure vessel for accommodating the irradiation supervision sample.
There are many difficulties in the manufacture of irradiation supervision tubes, such as half-shell bending, gas-filled sealing welding, temperature alloy and neutron injection detector. The CAP series of radiation supervision tubes are all abroad. Supply.
