Content:
bes methods and procedures that the staff of the U.S. Nuclear Regulatory Commission (NRC) considers acceptable when developing a comprehensive vibration assessment program (CVAP) for reactor internals (including steam dryers in boiling water reactor [BWR] nuclear power plants) during preoperational and startup testing. Applicability The NRC staff considers this methodology acceptable to support its review of applications for (1) nuclear reactor construction permits (CPs) or operating licenses (OLs) under Title 10 of the Code of Federal Regulations (10 CFR) Part 50, “Domestic Licensing of Production and Utilization Facilities,” (Ref. 1), (2) design certifications (DCs) and combined licenses (COLs) under 10 CFR Part 52, “Licenses, Certifications, and Approvals for Nuclear Power Plants” (Ref. 2), and (3) license amendment requests for extended power uprates (EPUs) at operating reactors. The staff also considers this methodology acceptable for use by licensees of operating plants planning significant plant modifications that might induce potential adverse flow effects on structures, systems, and components (SSCs) within the scope of this regulatory guide. Applicable Rules and Regulations • U.S. Code of Federal Regulations, Title 10, “Energy,” Part 50, “Domestic Licensing of Production and Utilization Facilities,” (10 CFR 50). • 10 CFR 50, Appendix A, “General Design Criteria for Nuclear Power Plants,” General Design Criterion (GDC) 1, “Quality Standards and Records,” requires that reactor internals be designed DG-1323, Page 2 and tested to quality standards commensurate with the importance of the safety function to be performed. • 10 CFR 50, Appendix A, GDC 4, “Environmental and Dynamic Effects Design Bases,” requires reactor internals to be designed to accommodate the effects of, and to be compatible with, the environmental conditions associated with normal operations, maintenance and testing. • 10 CFR 50, Appendix B, “Quality
