In addition, as part of its primary review responsibility for SRP Section 3.2.2, if the PWR pressurizer power-operated relief valves (PORVs) and block valves are relied upon to perform a safety-related function, such as plant cooldown in accordance with BTP 5-4, this organization will confirm the classification of the PORVs and block valves. 5.4.7-5 Revision 4 - March 2007 B. Reviews the effects of pipe breaks inside and outside of containment, such as pipe whip and jet impingement, as part of its primary review responsibilities for SRP Section 3.6.2. C. Determines that the components, piping, and structures are designed and tested in accordance with applicable codes and standards as part of its primary review responsibility for SRP Sections 3.9.1 through 3.9.3. D. Reviews adequacy of the inservice testing program of pumps and valves as part of its primary review responsibility for SRP Section 3.9.6. For new plant designs, the reviewer responsible for the review of reactor thermal hydraulic systems in PWRs should coordinate with the organization responsible for the mechanical engineering reviews to ensure that the RHR system configuration allows for full-flow testing of safety-related pumps and check valves and that provisions are made to allow for the use of advanced techniques to detect degradation and monitor system performance. 5. The organization responsible for quality assurance and maintenance reviews performs the following reviews: A. Evaluates the pre-operational and startup test programs to confirm that they are in conformance with the intent of Regulatory Guide 1.68 as part of its primary review responsibility for SRP Section 14.2 B.
