Irradiation study on structural materials for light water reactors using JMTR

Chimi, Yasuhiro; Nishiyama, Yutaka 

In the Fuels and Materials Irradiation Research Group, in order to provide the technical information for the safety regulation of the Japanese government on the ageing management technical evaluation for the current commercial light water reactors (LWRs), irradiation studies on the structural materials for LWRs (i.e. irradiation embrittlement of reactor pressure vessels and irradiation-assisted stress corrosion cracking (IASCC) of reactor core shroud) under simulated LWR water and irradiation conditions will be performed by using the Japan Materials Testing Reactor (JMTR), which will restart in FY 2012.
