meeting the requirements of the reactor core design under various DRAFT Rev. 3 - April 1996 3.9.4-4 normal operating and accident operating conditions in SRP Section 4.2. The SRXB 16 also reviews the functional design of reactivity control systems, including the CRDS and its design for protection against the effects of postulated piping and equipment failures, in SRP Section 4.6.17 2. The Materials Engineering Branch (MTEB)Materials and Chemical Engineering Branch 18 (EMCB) reviews the adequacy of programs for assuring the integrity of bolting and 19 threaded fasteners as part of its primary review responsibility for SRP Section 3.13 (proposed). The EMCB also will reviews the material aspects of CRDS in SRP Section 20 4.5.1. 3. The Plant Systems Branch (SPLB) verifies the adequacy of specified environments and 21 service conditions for equipment qualification and of the overall demonstration that components of the CRDS are qualified to perform their functions, as part of its primary review responsibility for SRP Section 3.11.22 For those areas of review identified above as part of the primary review responsibility of other branchesunder other SRP sections, the acceptance criteria necessary for the review and their methods of application are contained in the referenced SRP sections of the corresponding primary branch . 23 II. ACCEPTANCE CRITERIA EMEB acceptance criteria are based on meeting the requirements of the following regulations: 24 1A . GDC 1 and 10 CFR Part 50, §50.55a, as its relates to CRDS, requires that the CRDS be 25 designed to quality standards commensurate with the importance of the safety functions 26 to be performed. 2B. GDC 2, as it relates to CRDS, requires that the CRDS be designed to withstand the effects of an earthquake without loss of capability to perform its safety functions. 3C. GDC 14, as it relates to CRDS, requires that the RCPB portion of the CRDS be designed, constructed, and tested for the extremely low probability of leakage or
