Abstract

ABSTRACT It is the current practice of the Canadian Nuclear Safety Commission (CNSC) to expect the licensed operators to conduct a Periodic Safety Review (PSR) in support of the continued safe operation of their nuclear power facilities. One of the essential components of the PSR is the determination of the actual condition of structures, systems and components (SSCs) important to safety, including the confirmation that the existing aging management arrangement will assure fitness for service (FFS) of these SSCs for the continued operation, and the presence of records demonstrating evidence that activities and actions are undertaken to maintain SSCs important to safety fit for service.
This paper describes the regulatory expectations for the use of PSR in support of continued safe operation of a nuclear generating station. The paper specifically delineates the regulatory expectations regarding the necessary information required to maintain and report on the actual condition of SSCs important to safety, the arrangements (for example, programs, processes, procedures, instructions, tools) that the licensee must establish to maintain the FFS of these SSCs, and the database that supports the continual monitoring of the condition of these SSCs important to safety. Some lessons learned from the recent Canadian experience are presented and discussed.
