SAFETY FUNCTIONS, DESIGN CRITERIA, AND SSC SAFETY CLASSIFICATION This chapter of the SE describes the U.S. Nuclear Regulatory Commission staffs (the staffs) review and evaluation of Kemmerer Unit 1 (KU1) PSAR chapter 5, which describes the safety classification of structures, systems, and components (SSCs), the safety-significant probabilistic risk assessment (PRA) safety functions (PSFs), and the principal design criteria (PDCs).
The applicable regulatory requirements for the staffs evaluation of the SSC safety classification, PSFs, and PDCs, are as follows:
Title 10 of the Code of Federal Regulations (10 CFR) 50.34(a)(1), (3), (4), and (5) -
Contents of Applications; Technical Information 10 CFR 50.35, Issuance of Construction Permits 10 CFR Part 50, Appendix A, General Design Criteria for Nuclear Power Plants The applicable guidance for the staffs evaluation of the SSC safety classification, PSFs, and PDCs, are as follows:
