tight integrity. These evaluations are performed under SRP Section 5.2.4. E. The organization responsible for the review of reactor coolant pressure boundary leakage detection reviews design features, analytical techniques, and procedural measures associated with reactor coolant pressure boundary leakage detection systems under SRP Section 5.2.5, “Reactor Coolant Pressure Boundary Leakage Detection.” F. The organization responsible for the review of thermal-hydraulic systems in BWRs/PWRs assesses the functional aspects of valves within, and connected to, the reactor coolant pressure boundary under SRP Sections 5.4.6, “Reactor Core Isolation Cooling System,” and 5.4.7, “Residual Heat Removal (RHR) System.” 5.4-6 Revision 2 - March 2007 G. The organization responsible for the review of the BWR and PWR emergency core cooling system (primary reviewer), and the organizations responsible for the review of other systems and technical areas related to the BWR and PWR emergency core cooling systems, assess the functional aspects of valves within, and connected to, the reactor coolant pressure boundary under SRP Section 6.3, “Emergency Core Cooling System.” H. The organization responsible for mechanical engineering reviews assesses methods of analysis (e.g., seismic and vibratory loadings, and dynamic analyses), and structural integrity of RCS (and subsystem) valves under SRP Sections 3.9.1, 3.9.2, and 3.9.3. I. The organization responsible for the review of component performance and testing reviews the functional design and qualification provisions and IST programs for certain safety-related valves typically designated as Class 1, 2, or 3 under Section III of the ASME Code under SRP Section 3.9.6. The review may include other valves not categorized as ASME Code Class 1, 2, or 3 if the staff considers them to be safety related. J. The organization responsible for mechanical engineering reviews (primary reviewer), and the organization responsible for reviews of
