lity of Tier 1 information regarding the arrangement of reactor and core cooling systems, including design considerations for preventing intersystem loss-of-coolant accidents in SRP Section 14.3.4. 3. The Containment Systems and Severe Accident Branch (SCSB) determines the acceptability of Tier 1 information regarding the requirements for and arrangement of severe accident design features in SRP Section 14.3.11. Secondary Review Branch Responsibilities 1. The SPLB determines the acceptability of Tier 1 information regarding the arrangement of major plant SSCs, the design features of SSCs and ability of structures to withstand fires, internal and external flooding, internal and external missiles, pipe breaks, and the design of building HVAC systems in SRP Section 14.3.7. 2. The PERB determines acceptability of Tier 1 information regarding the emergency preparedness and radiation protection aspects of the structures in SRP Section 14.3.8. 3. The PSGB determines the acceptability of Tier 1 information regarding the design features for safeguards in SRP Section 14.3. II. ACCEPTANCE CRITERIA The acceptance criteria for ITAAC are based on meeting 10 CFR 52.97(b)(1), which sets forth the comprehensive requirements for ITAAC. For design certification reviews, the scope of ITAAC is limited to the scope of the certified design as required by 10 CFR 52.47(b). The reviewer should primarily utilize the NRC rules and regulations to review the top level commitments in Tier 1. Other sources of review guidelines include RGs, SRP guidelines, and PRA insights from the standard design safety and severe accident analyses and operating experi- ence. If applicable, the staff also must adhere to policy decisions by the Commission. Examples of these are contained in the SRM related to SECY-90-016, "Evolutionary Light Water Reactor Certification Issues and Their Relationship to Current Regulatory Requirements," as modified by the Commission guidance in the SRM related to SECY-93-087,
