Content:
Cases listed in Regulatory Guide 1.147 provide additional guidance or alternatives acceptable to the staff. b. The applicant should have systems and procedures to detect and correct leaks in the RCPB and to monitor the integrity of bolted joints. c. The applicant's procedures for refurbishment, cleaning, replacement, and return-to-service should be reviewed with respect to mechanical fasteners. d. Maintenance procedures should comply with EPRI NP-5067, Volume 1 or 2, as appropriate. e. Additional guidance on acceptable maintenance practices can be found in EPRI NP-5769 (as endorsed in Generic Letter 91-17 and NUREG-1339) and in standard textbooks such as Bickford (Ref. 29). 3.13-13 DRAFT Rev. 0 - April 1996 f. Where potential for degradation of threaded fasteners from borated-water corrosion and/or stress-corrosion cracking exists, such degradation should be addressed to the extent practical.28 C. Acceptance criteria for threaded fastener applications in pressure-retaining joints of seismic Category I components other than the RCPB or RCS for areas of review described in subsection I.C include the following: 1. General requirements for systems and components containing such fasteners are described in 10 CFR 50.55a and General Design Criteria 1, 2, and 4. Threaded fasteners in these applications are part of Quality Group B, C, and D components, as described in Regulatory Guide 1.26. Quality Group B and C fasteners must meet the specific requirements for ASME Code Class 2 or 3 components, respectively. Fasteners in Quality Group D components must meet the quality standards described in Table 1 of Regulatory Guide 1.26 for each specific application. 2. Design requirements (including material selection and assurance of material compatibility) for threaded fasteners should include the following: a. Design criteria for threaded fasteners should comply with the following industry standards (application of specific subsections and appendices of the ASME Code is summarized
