Content:
threaded fasteners for joints in seismic Category I structures other than component supports or core support structures. The Manual of Steel Construction (published by the American Institute of Steel Construction, or AISC) provides acceptable data and details for design and installation of such structures. d. Threaded fastener application for electrical equipment, other SSCs, or items otherwise not covered in a, b, or c, above, should conform to the manufacturer's plans and specifications and comply with sound engineering practices. e. General guidance on the design of bolted mechanical (as opposed to structural) fasteners and joints is found in standard textbooks such as Bickford (Ref. 29); EPRI NP-6316; and Volumes 1, 11, and 13 of the ASM Metals Handbook. f. 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 design. 3. Maintenance requirements should include the following: a. The applicant should have procedures for refurbishment, cleaning, replacement, and return-to-service. b. Maintenance procedures should be in accordance with EPRI NP-5067, Volume 1 or 2, as appropriate. c. 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). d. 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 maintenance procedures.30 E. Acceptance criteria for threaded fastener applications in SC I-related SSCs for areas of review described in subsection I.C are as follows: DRAFT Rev. 0 - April 1996 3.13-16 1. General requirements for SSCs containing such fasteners are described in 10 CFR
