概要
Proper management of neutron irradiation damage on structural materials is important to ensure the Lealth of long-life fast breeder reactor (FBR) plants. Therefore, the effective index f or irradiation amage or the combination of those should be developed. In this study, the effects of dose, helium, nd the ratio of helium to dose on tensile and creep properties of FBR gra de type 316 stainless steel were investigated in the assumed irradiation damage range of FBR structural materials, that is, up to bout 1 displacement per atom for dose and up to about 30 appm for helium. As result, it was shown hat dose is the most promising. In addition, a nondestructive evaluation method of dose using a -ibrating sample magnetometer is also introduced.
