Reliability assurance program for the APR1400 DC

KHNP is preparing the APR1400 design for U.S.NRC Design Certification (DC), for which the reference plant is Shin Kori units 3 and 4, by applying the code and standards of NRC issued before submitting the APR1400 design control documents. One of the important design activities, comparing to the licensing of the domestic licensing of new plants, is the requirement for Reliability Assurance Program (RAP). RAP is required in RG 1.206 and the associated acceptance criteria is described in SRP 17.4 and ISG DC/COL ISG 018. The RAP for the APR1400 during the design phase is performed in accordance with the U.S. regulatory requirements and associated guides. This paper provides the methodology, implementation process, and preliminary results of the APR1400 RAP
