概要
Experimental evaluations were conducted to verify whether the significant SCC growth is possible or not in Ni base weld metals during cold shutdown period of light-water reactors. As a result, it has been confirmed that the SCC growth rate decreases with decreasing temperature and the growth rate below 100 °C is low enough to be neglected in plant evaluations.
