The SRXB also reviews the design of systems that interface with the reactor coolant system with regard to the capability of the interfacing system to withstand full RCS pressure as part of its primary review responsibility for SRP Section 3.12 (proposed).4 In addition, the SRXB will coordinate its review with the evaluations of other branches that have primary review responsibility for other portions of the overpressure protection as follows: 1. The Human Factors Assessment Branch (LHFB)Quality Assurance and Maintenance Branch (HQMB) , as part of its primary review responsibility for SRP Section 14.2, 5 reviews proposed preoperational and initial startup test programs to assure that overpressure components will perform their safety function. 2. The Mechanical Engineering Branch (EMEB), as part of its primary review responsibility for SRP Sections 3.2.1 and 3.2.2, reviews seismic design criteria for components of the overpressure protection system. 3. The EMEB, as part of its primary review responsibility for SRP Section 3.10 and the Plant Systems Branch (SPLB) for SRP Section 3.11 , reviews installation criteriaseismic 6 7 and dynamic qualification for components of the overpressure protection system. 8 4. The Plant Systems Branch (SPLB), as part of its primary review responsibility for SRP Section 3.11, reviews environmental qualification for components of the overpressure protection system.9 5. The Materials and Chemical Engineering Branch (EMCB) reviews the fracture toughness of the RCPB and reactor vessel as part of its primary review responsibility for SRP Sections 5.2.3 and 5.3.1. The EMCB also reviews the pressure-temperature limits and pressurized thermal shock analysis as part of its primary review responsibility for SRP Section 5.3.2.10 6. The Instrumentation and& Controls Systems Branch (SHICB) , as part of its primary 11 review responsibility for SRP Section 7.6, reviews the adequacy of controls and instrumentation for the automatic and manual actuation
