part of its primary review responsibility for SRP Section 3.13 (proposed).9 2. Evaluates the portions of the control rod drive system that are part of the reactor coolant pressure boundary (RCPB) and verifies that the materials of construction and related fabrication controls satisfy the criteria applicable to RCPB materials, as part of its primary review responsibility for SRP Section 5.2.3.10 4.5.1-3 DRAFT Rev. 3 - April 1996 3. Evaluates portions of control rod drives that are reactor vessel attachments or appurtenances and verifies that the materials of construction and related fabrication controls satisfy the criteria applicable to reactor vessel materials, as part of its primary review responsibility for SRP Section 5.3.1.11 4. 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 control rod drive structural materials, 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)."12 In addition, MTEBEMCB will coordinate other branches' evaluations that interface with the 13 overall review of the system as follows: 1. theThe Mechanical Engineering Branch (MEBEMEB ) reviews the mechanical aspects 14 of the control rod drive system other than the reactivity control elements as part of its 15 primary responsibility for SRP Section 3.9.4. 2. The Core Performance Branch (CPB) Reactor Systems Branch (SRXB) reviews the 16 mechanical design, thermal performance, and chemical compatibility of the reactivity control elements as part of its primary responsibility for SRP Section 4.2. 3. The Emergency Preparedness and Radiation Protection Branch (PERB) evaluates the plant design, including the selection of materials to minimize activation products, to verify that occupational radiation exposures will be as low as is reasonably achievable
