material parameters. iv. Relevant industry codes and classifications applied to the system analysis for low-temperature operation should be clearly identified as specified in RIS 2004-04. Assumptions used in the analysis, including the initial plant conditions and system parameters, should also be identified and justified. The reviewer should identify studies that show the sensitivity of the system’s performance to variations in these conditions, parameters, and characteristics. The reviewer should consult Section 5.2.2 of the FSAR for new plant designs to obtain insight on the overpressure protection methodology. 2. Testing and Inspections. To ensure operational readiness, the overpressure protection system should be testable. The reviewer should verify the following: A. Tests for SRV operability are scheduled to be conducted as specified in Section III of the ASME Code Article NB-7000. B. For PWRs, PORV and PORV block-valves are included in the inservice inspection program as specified in Generic Letter No. 90-06. 5.2.2-12 Revision 3 - March 2007 C. For PWRs, PORV and PORV block-valves are included in the QA and preventive maintenance program as specified in Generic Letter No. 90-06. 3. Technical Specifications. The review includes the technical specifications to ensure that they are adequate in regard to limiting conditions of operation and periodic surveillance testing. The review should include the following: A. Confirm the suitability of the limiting conditions of operation, including the proposed time limits and reactor operating restrictions for periods when system equipment is inoperable because of repairs and maintenance. B. Verify that the frequency and scope of periodic surveillance testing are adequate. C. Verify compliance with the technical specification guidance of Generic Letter No. 90-06 for PORVs, PORV block-valves, and the LTOP system (PWRs only). D. Verify compliance with TMI Action Plan Item II.K.3.3 of NUREG-0737 regarding reporting of SRV
