rosion resistance, and fabricability. 4.5.2-3 DRAFT Rev. 3 - April 1996 Review Interfaces17 EMCB also performs the following related reviews under the SRP Sections indicated: 1. Evaluates the adequacy of programs for assuring the integrity of bolting and threaded fasteners as part of its primary review responsibility for SRP Section 3.13 (proposed).18 2. The Chemical Engineering Branch (CMEB) reviewsEvaluates the areas of corrosion and compatibility of thesereactor internals and core support structures materials with the expected environment during service as part of its primary review responsibility of SRP Section 5.2.3.19 3. Determines the acceptability of the reactor coolant chemistry and associated chemistry controls (including additives such as inhibitors) as it relates to corrosion control and compatibility with materials to be exposed to reactor coolant, as part of its primary review responsibility for SRP Sections 5.4.8 "Reactor Water Cleanup System (BWR)" and 9.3.4 "Chemical and Volume Control System (PWR)."20 In addition, EMCB will coordinate other branches' evaluations that interface with the overall review of the reactor internals and core support structures as follows:21 1. The Mechanical Engineering Branch (EMEB) determines the adequacy of design fatigue curves for reactor internals and core support structures materials with respect to cumulative reactor service-related environmental and usage factor effects and consideration of each combination of loadings, as part of its primary review responsibilities for SRP Sections 3.9.1 and 3.9.3.22 2. The EMEB also reviews the reactor internals and core support structures with respect to their mechanical design adequacy to withstand design and service loading combinations, as part of its primary responsibility for SRP Section 3.9.5.23 3. The Emergency Preparedness and Radiation Protection Branch (PERB) evaluates the plant design, including the selection of materials to minimize activation products, to verify
