roperties and welding controls to resist thermal aging effects over the design life are reviewed. Since welds on such materials are difficult to inspect using ultrasonic techniques, the inspectability is also reviewed.25 DRAFT Rev. 3 - April 1996 5.2.3-6 Inservice inspection requirements for the RCPB are described in SRP Section 5.2.4, "Inservice Inspection and Testing of Reactor Coolant Pressure Boundary."26 Review Interfaces: EMCB also performs the following related reviews under the SRP Sections indicated:27 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).28 2. 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 RCPB 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)."29 In addition, the EMCB will coordinate other branches' evaluations that interface with the overall review of the RCPB materials as follows:30 1. The Mechanical Engineering Branch (EMEB) determines the adequacy of the design for structural integrity of components and their supports including the adequacy of design fatigue curves for RCPB materials with respect to cumulative reactor service-related environmental and usage factor effects, as part of its primary review responsibility for SRP Section 3.9.3.31 2. The Civil Engineering and Geosciences Branch (ECGB) determines the acceptability of inservice inspection requirements specified for the RCPB and the effectiveness of proposed inspection and examination techniques to provide early detection and adequate evaluation of defects in materials and weldments used in the RCPB, as part of its primary review responsibility for SRP Section 5.2.4.32 3.
