Invited Talk
During operation several components at the Spallation Neutron Source (SNS) are exposed to high energy radiation that alter mechanical and physical properties, which limits their useful lifetime. Components are also occasionally removed from service due to leaks or another failure mechanisms that prohibit reliable operation. The SNS maintains a rigorous post irradiation examination (PIE)...

SINQ Target-11 was in operation in 2015 and 2016. It was shut-down due to an incident in June 2016, during which the pressure drop in the cooling water loop increased significantly, and meanwhile, the activity of the cooling water also increased tremendously. The evidence indicated a serious failure of the target. As this is the first severe failure since SINQ was in operation in 1997, the...
