ection XI, Subsection IWC, for ASME Code Class 2 fasteners larger than 5.1 cm (2 in) in diameter. No specific provisions are offered in Section IWC or IWD of the ASME Code regarding inservice tests or inspections for Class 2 fasteners smaller than 5.1 cm (2 in) in diameter, Class 3 fasteners, and other seismic Category I fasteners. b. The applicant should have systems and procedures to detect and correct leaks and to monitor the integrity of bolted joints. c. The applicant's procedures for refurbishment, cleaning, replacement, and return-to-service should be reviewed. d. Maintenance procedures should be in accordance 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 standard textbooks such as Bickford (Ref. 29).29 D. Acceptance criteria for threaded fastener applications for nonpressure-retaining seismic Category I components, seismic Category I component supports, and seismic Category I structures for areas of review described in subsection I.C are as follows: 1. General requirements for SSCs containing such fasteners are described in 10 CFR 50.55a and General Design Criteria 1, 2, and 4, as outlined in subsection I.B. 2. Design requirements (including material selection and assurance of material compatibility) should include the following: a. ASME Code, Section III, Subsection NG, provides guidance for the design of core support structures, including threaded fasteners. 3.13-15 DRAFT Rev. 0 - April 1996 b. ASME Code, Section III, Subsection NF, provides guidance for the design of ASME Code Class 1, 2, and 3 component supports, including threaded fasteners. c. The ANSI/AISC N690-84 Code provides guidance for the design of threaded fasteners for joints in seismic Category I structures other than component supports or core support structures.
