Abstract

Abstract

Periodic test frequency shall be adjusted following the refueling cycle extension in nuclear power plants. This paper introduces the screening principle and verification methods for verification of periodic test frequency extension, and then takes containment spray system as an example, the feasibility of periodic test frequency extension is verified by the reliability analysis method. The quantitative result demonstrates that the reduction of system availability is acceptable to periodic test frequency extension.
