1 REVIEW RESPONSIBILITIES Primary - Civil Engineering and Geoscience Branch (ECGB) Secondary - None I. AREAS OF REVIEW ECGB reviews the Design Control Document (DCD) submitted by the applicant. Review responsibilities may be consistent with those contained in Appendix B to SRP Section 14.3. ECGB has primary review responsibility for Tier 1 piping design and components and legends for figures. ECGB reviews Tier 1 for issues regarding structural, mechanical, materials, and chemical engineering. In addition, ECGB reviews Tier 1 for treatment of MOVs, POVs, and check valves, as well as dynamic qualification, welding, and safety classification of SSCs. Review Interfaces SRP Section 14.3 provides general guidance on review interfaces. ECGB performs related reviews and coordination activities, as requested by other branches, for issues in Tier 1 as discussed above. ECGB also performs the following reviews under the SRP sections indicated: 1. ECGB determines that Tier 1 information is adequate for site parameters for the design in SRP Section 14.3.1. 2. ECGB determines that Tier 1 information is adequate for structural aspects of the SSCs of the design in SRP Section 14.3.2. DRAFT Rev. 0 - April 1996 14.3.3-2 In addition, ECGB will coordinate other branches' evaluations that interface with the overall review of the systems as follows: 1. The Reactor Systems Branch (SRXB) determines the acceptability of Tier 1 information regarding the arrangement of reactor and core cooling SSCs in SRP Section 14.3.4. 2. The Plant Systems Branch (SPLB) determines the acceptability of Tier 1 information regarding the ability of SSCs to withstand the environmental effects of high-energy line breaks in SRP Section 14.3.7. 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
