Content:
d. b. For all components the following points are reviewed: (1) The qualification procedures for welds in areas of limited accessibility are reviewed. (2) The cleaning procedures are reviewed. (3) For tubular products, the nondestructive examination procedures are reviewed for conformance with the ASME Code. c. For carbon or low alloy steel components, the controls placed on the welding procedures are reviewed. 3. Erosion/Corrosion The following areas of erosion/corrosion mitigation for the steam and feedwater systems are reviewed:6 a. Utilization of erosion/corrosion resistant materials.7 b. Specification of an adequate corrosion allowance.8 c. Consideration of minimizing the effects of erosion/corrosion in the design of piping.9 Review Interfaces:10 EMCB also performs the following reviews under the SRP sections indicated:11 1. Reviews 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).12 2. Reviews the material selection and fabrication process controls for stainless steel as part of its primary review responsibility for SRP Secton 5.2.3.13 10.3.6-3 DRAFT Rev. 3 - April 1996 MTEBIn addition, EMCB will coordinate other branches' evaluations that interface with the 14 overall review of steam and feedwater system materials as follows: 1. The Mechanical Engineering Branch (EMEB) reviews the acceptability of the seismic 15 16 and quality group classifications for system components as part of its primary review responsibility for SRP Sections 3.2.1 and 3.2.2. 2. The review for Quality Assurance is coordinated and performed by the Quality Assurance and Maintenance Branch (HQMB) as part of its primary review 17 responsibility for SRP Sections 17.1 through 17.317.0. 18 3. The Civil Engineering and Geosciences Branch (ECGB) reviews surveillance programs to verify inclusion of erosion/corrosion monitoring of steam and feedwater system materials as part of its
