Numerical investigation on stress corrosion cracking behavior of dissimilar weld joints in pressurized water reactor plants

Lingyan Zhao, He Xue, Fuqiang Yang, Yaohong Suo

There have been incidents recently where stress corrosion cracking (SCC) observed in the dissimilar metal weld (DMW) joints connecting the reactor pressure vessel (RPV) nozzle with the hot leg pipe. Due to the complex microstructure and…

Leak-Before-Break methodology applied to different piping materials: a performance evaluation

Israel Gleybson Ferreira da Silva, Arnaldo Homobono Paes de Andrade, Waldemar Alfredo Monteiro

This paper presents a study of the application of Leak-Before-Break (LBB) to nuclear piping using three different materials. Based on the fracture mechanics, the LBB concept considers that a leakage from a crack can be detected before it…
