welder or welding operators for limited accessibility may be waived provided that 100% radiographic and/or ultrasonic examination of the completed welded joint is performed. Examination procedures and acceptance standards should meet the requirements of the ASME Section III of the Code. Records of the examination reports and radiographs should be retained and made part of the Quality Assurance Documentation for the completed weld. (4) Regulatory Guide 1.43, "Control of Stainless Steel Weld Cladding of Low-Alloy Steel Components," provides criteria to limit the occurrence of underclad cracking in low-alloy steel safety-related components clad with stainless steel. These criteria require that material known to have susceptibility to underclad cracking not be weld clad by high-heat-input welding processes and be qualified for use to demonstrate that underclad cracking is not induced. c. For nondestructive examination of ferritic steel tubular products, the requirements of GDC 1, GDC 30, and §50.55a regarding quality standards are met by compliance with the applicable provisions of the ASME Code. The acceptance criteria are given in Section III of the Code, Paragraphs NB-2550 through NB- 2570.68 4. Fabrication and Processing of Austenitic Stainless Steel a. The requirements of GDC 4 relative to compatibility of components with 69 environmental conditions are met regarding measures to avoid sensitization in austenitic stainless steels. The acceptance criteria for testing, alloy compositions, and heat treatment, to avoid sensitization in austenitic stainless steels, are covered in Regulatory Guide 1.44, "Control of the Use of Sensitized Stainless Steel,"70 and additional criteria for BWRs are specified in Attachment A to Generic Letter 88-01 based upon the technical information provided in NUREG-0313. Similar recommendations related to minimizing stress corrosion cracking in susceptible piping of BWRs are described in NUREG-0313.71 Regulatory Guide 1.44 also identifies
