4. The Mechanical Engineering Branch (EMEB) reviews issues related to seismic and quality group classification of threaded fasteners as part of its primary review responsibility for SRP Sections 3.2.1 and 3.2.2. (Threaded fasteners are classified as part of the component or support. See subsection I.C.3, above.) 5. The EMEB reviews issues related to piping, mechanical components, and mechanical and electrical component supports as part of its primary review responsibility for SRP Sections 3.6.1, 3.6.2, 3.9.2, and 3.9.3.23 6. The Quality Assurance and Maintenance Branch (HQMB) reviews programmatic aspects of QA, including those aspects regarding fasteners, as part of its primary review responsibility under SRP Chapter 17.24 3.13-9 DRAFT Rev. 0 - April 1996 For those areas of review identified as part of review under other SRP sections, the acceptance criteria and methods of application are contained in the referenced SRP sections.25 II. ACCEPTANCE CRITERIA The acceptance criteria are based on meeting the relevant requirements of 10 CFR 50.55a, 10 CFR 50.60, GDC 1, GDC 2, GDC 4, GDC 14, GDC 15, GDC 30, GDC 31, GDC 32, Appendix B of 10 CFR 50, and Appendix G of 10 CFR 50, as described in subsection I.B. A. General acceptance criteria for all threaded fastener applications should include the following: 1. Installation a. Installation procedures should comply with EPRI NP-5067, Volume 1 or 2, as appropriate. b. Additional guidance on acceptable installation practices can be found in EPRI NP-5769 (as endorsed in Generic Letter 91-17 and NUREG-1339), standard textbooks such as Bickford (Ref. 29), EPRI NP-6316, and the Metals Handbook published by the American Society of Metals (ASM). c. To the extent practical, minimization of degradation and failure of support fasteners or embedments (e.g., resulting from fatigue, corrosion, inadequate installation, vibration, water hammer, or earthquake) should be emphasized in the installation procedures. 2.
