tory Guide 1.34, "Control of Electroslag Weld Properties," and provide assurance that welds fabricated by the process will have high integrity and will have a sufficient degree of toughness to furnish adequate safety margins during operating, testing, maintenance, and postulated accident conditions. Conformance with DRAFT Rev. 3 - April 1996 5.2.3-22 the recommendations of Regulatory Guide 1.34 also satisfies the quality standards requirements of GDC 1, GDC 30, and §50.55a. The controls imposed on welding ferritic steels under conditions of limited accessibility are in accordance with the recommendations of Regulatory Guide 1.71, "Welder Qualification for Areas of Limited Accessibility," and provide assurance that proper requalification of welders will be required in accordance with the welding conditions. These controls also satisfy the quality standards requirements of GDC 1, GDC 50, and §50.55a. The controls imposed on weld cladding of low-alloy steel components by austenitic stainless steel are in accordance with the recommendations of Regulatory Guide 1.43, "Control of Stainless Steel Weld Cladding of Low-Alloy Steel Components." These controls provide assurance that practices that could result in underclad cracking will be restricted. The controls also satisfy the quality standards requirements of GDC 1, GDC 30, and §50.55a. The controls to avoid stress corrosion cracking in reactor coolant pressure boundary components constructed of austenitic stainless steels limit yield strength of cold-worked austenitic stainless steels to 620 MPa (90,000 psi) maximum and conform to the 115 recommendations of Regulatory Guides 1.44, "Control of the Use of Sensitized Stainless Steel," [for BWRs only] the positions of Generic Letter 88-01 or NUREG-0313, Revision 2 recommendations, and 1.37, "Quality Assurance 116 Requirements for Cleaning of Fluid Systems and Associated Components of Water Cooled Nuclear Plants." The controls followed in accordance with these
