urrences. With respect to absorbed energy in J (ft-lbs) and lateral expansion as shown by Charpy V-notch (C ) impact tests, all 61 v materials shall meet the acceptance standards of Article NB-2300 of the Code, Section III, and the requirements of Sections IV.A.2 and IV.A.3 of Appendix G, 10 CFR Part 50, as follows: (1) The special acceptance requirements for fracture toughness of reactor vessels are covered by Standard Review Plan Section 5.3.1, "Reactor Vessel Materials." (2) Materials for piping (i.e., pipes, tubes, and fittings), pumps, and valves, excluding bolting materials, shall meet the requirements of the Code, Section III, Paragraph NB-2331 or NB-2332 (as applicable based upon thickness), and Appendix G, Paragraph G-3100. The required C values v for piping, pumps, and valves are specified in Table NB-2332(a)-1 of the Code, Section III.62 5.2.3-9 DRAFT Rev. 3 - April 1996 (3) Materials for bolting for which impact tests are required shall meet the requirements of the Code, Section III, Paragraph NB-2333. (4) Calibration of instruments and equipment shall meet the requirements of the Code, Section III, Paragraph NB-2360. b. The acceptance criteria for control of ferritic steel welding are based upon the following regulatory guides and ASME Code provisions to satisfy the quality standards requirements of GDC 1, GDC 30, and §50.55a: (1) The amount of specified preheat must be in accordance with the requirements of the Code, Section III, Appendix D, Paragraph D-12001210 , supplemented by Regulatory Guide 1.50, "Control of 63 Preheat Temperature for Welding of Low Alloy Steel."64 The supplemental acceptance criteria for control of preheat temperature are as follows: (a) The welding procedure qualification requires that minimum preheat and maximum interpass temperatures be specified and that the welding procedure be qualified at the minimum preheat temperature. For production welds, the preheat temperature should be maintained until a post-weld heat treatment
