THE MITIGATION OF IGSCC OF BWR INTERNALS WITH HYDROGEN WATER CHEMISTRY

Intergranular stress corrosion cracking (IGSCC) in BWR reactor interna ls is a well understood phenomenon which can incur considerable remedi al costs. This paper describes the basis for establishing and confirmi ng the conditions of mitigation of the various components. Methods to deal with undesirable side-effects of hydrogen water chemistry will al so be reviewed. Finally, the use of new technologies to deal with thes e side-effects will be addressed.
