3 the operability assurance program for containment isolationpurge and vent valves as 14 part of its primary review responsibility for SRP Section 3.10. B. The Structural Engineering Branch (SEB)Civil Engineering and Geosciences Branch (ECGB) will review the structural design of the containment isolation system as part of 15 its primary review responsibility for SRP Section 3.8 to ensure adequate protection against earthquakes. C. The Instrumentation and Control Systems Branch (ICSB)Instrumentation & Controls Branch (HICB) will evaluate the actuation and control features for isolation valves as 16 part of its primary responsibility for SRP Section 7.5. The Equipment Qualification Branch (EQB)HICB will also review sensing and 17 actuation instrumentation of the plant protection system located both inside and outside of containment as part of its primarysecondary review responsibility for 18 SRP Sections 3.10 and 3.11. D. The Accident Evaluation Branch (AEB)Emergency Preparedness and Radiation Protection Branch (PERB) will review the radiological dose consequence analysis for 19 the release of containment atmosphere prior to closure of containment isolation valves in lines that provide a direct path to the environs, as part of its secondaryprimary review 20 responsibility for SRP Section 15.6.5, Appendix A.21 E. The Reactor Systems Branch (RSB)(SRXB) will review the closure time for 22 containment isolation valves in lines that provide a direct path to the environs with respect to the prediction of onset of accident-induced fuel failure as part of its primary review responsibility for SRP Section 15.6.5. F. The review of proposed technical specifications pertaining to operability and leakage-rate testing of the isolation barriers, and the closure time for containment isolation valves, is performed by the Licensing Guidance Branch (LGB)Technical Specifications Branch (TSB) at the operating license stage of review, as part of its primary review 23 responsibility for SRP
