| Abstract: | In nuclear power plant,class 1E cable is a kind of important equipment which is necessary for safety systems to perform their specified safety functions in normal condition,during and post design basis events.So the class 1E cable must be qualified according to the qualification plan and procedure which is in conformity with the requirements in the relevant standards.The review for the class 1E cable equipment qualification process and documents is an important aspect of nuclear safety equipment review.The qualified sample selection,thermal life evaluation of critical materials and acceleration aging conditions are discussed.Considering the class 1E cable qualification practices at home and abroad,reviewers propose some review points and technical positions related to the three mentioned issues. |
