NUREG-0800 U.S. NUCLEAR REGULATORY COMMISSION STANDARD REVIEW PLAN BRANCH TECHNICAL POSITION 5-3 FRACTURE TOUGHNESS REQUIREMENTS REVIEW RESPONSIBILITIES Primary - Organization responsible for the review of component integrity issues related to reactor vessels Secondary - None A. BACKGROUND The U.S. Nuclear Regulatory Commission (NRC) requirements regarding fracture toughness, pressure-temperature limits, material surveillance, and pressurized thermal shock (PTS) (pressurized-water reactor (PWR) only) are contained in Appendices A, G, and H to Title 10 of the Code of Federal Regulations (10 CFR) Part 50, “Domestic Licensing of Production and Utilization Facilities”; and in 10 CFR 50.61 “Fracture toughness requirements for protection against pressurized thermal shock events,” or 10 CFR 50.61a, “Alternate fracture toughness requirements for protection against pressurized thermal shock events.” These requirements also refer to relevant sections of the American Society of Mechanical Engineers (ASME) Code as incorporated by reference in 10 CFR 50.55a, “Codes and standards” (hereafter the ASME Code). Some sites have implemented Pressure Temperature Limit Reports (PTLR), approved via license amendment consistent with the guidance in Generic Letter (GL) 96-03, “Relocation BTP 5-3-2 Draft Revision 3 – July 2018 of the Pressure Temperature Limit Curves and Low Temperature Overpressure Protections System Limits,” which relocate portions of the subject requirements from the Technical Specifications (TS).
