Method and system for monitoring stress corrosion cracking of spent nuclear fuel storage metal canisters

摘要

The present invention is a monitoring method and system for detecting stress corrosion cracking of a metal canister in which spent nuclear fuel is stored, by attaching an electrically conductive composite and measuring in real time whether a non-conductive phenomenon occurs inside the electrically conductive composite. , The non-conducting observation step is composed of a non-conducting observation step that observes the occurrence and occurrence of stress corrosion cracking at the welding site in advance. By preparing, radiation exposure can be minimized, the system can be recycled under certain conditions, and it is intended to provide a method and system for monitoring stress corrosion cracking that can be driven without a separate power supply for a long time.
