ing processes used for welding the reactor vessel and its appurtenances have been identified and found to be qualified in accordance with the requirements of Code Sections III and IX. Qualification in accordance with the Code provisions meets the requirements of GDC 1, GDC 30, and §10 CFR 50.55a concerning 91 quality standards. 5. When welding components of ferritic steels as identified in Item 4 above, Code controls are supplemented by conformance with the recommendations of regulatory guides as follows: a. The controls imposed on welding preheat temperatures are in conformance with the recommendations of Regulatory Guide 1.50, or an acceptable alternative,92 DRAFT Rev. 2 - April 1996 5.3.1-18 "Control of Preheat Temperature for Welding of Low-Alloy Steel," since these controls provide reasonable assurance that cracking of components made from low alloy steels will not occur during fabrication and minimize the potential for subsequent cracking. These controls also satisfy the quality standards requirements of GDC 1, GDC 30, and §10 CFR 50.55a. 93 b. The controls imposed on electroslag welding of ferritic steels are in conformance with the recommendations of Regulatory Guide 1.34, "Control of Electroslag Weld Properties," because the welds fabricated by the process will ensure high integrity and will have a sufficient degree of toughness to furnish adequate safety margins. These controls satisfy the quality standards requirements of GDC 1, GDC 30, and §10 CFR 50.55a. 94 c. The controls imposed during weld cladding of ferritic steel components are in conformance with the recommendations of Regulatory Guide 1.43, "Control of Stainless Steel Weld Cladding of Low-Alloy Steel Components," because the process used provides reasonable assurance that under-clad cracking will not 95 occur during the weld cladding process. These controls satisfy the quality standards requirements of GDC 1, GDC 30, and §10 CFR 50.55a. 96 6. When welding components of austenitic stainless
