"Control of Electroslag Weld Properties." These criteria specify acceptable solidification patterns for qualification of austenitic stainless steel welds and the basis for verifying conformance during production welding. Regulatory Guide 1.71, "Welder Qualification for Areas of Limited Accessibility," provides the following criteria for requalification of welders: (1) The performance qualification should require testing of the welder when conditions of accessibility to a production weld 5.2.3-9 Rev. 2 - July 1981 are less than 30 to 35 cm (12-14 inches) in any direction from the joint. (2) Requalification is required for different restricted accessibility conditions or when other essential variables listed in the Code, Section IX, are changed. An-alternate acceptance criterion is as stated in subsection II.3.b of this SRP section. e. For nondestructive examination of austenitic stainless steel tubular products, the quality standards requirements of GDC 1, GDC 30, and §50.55a are met by compliance with the applicable provisions of the ASME Code. The acceptance criteria are given in Section III of the Code, Paragraph NB-2550. (Item II.4.e. is applicable to material reviewed by MTEB as specified in item I.4.e.) III. REVIEW PROCEDURES The reviewer will select and emphasize material from the procedures described below, as may be appropriate for a particular case. For each area of review described in subsection I of this SRP sectionthe following review procedures are followed: 1. Material Specifications The material specifications for each major pressure-retaining component or part used in the RCPB are compared with the acceptable specifications listed in the Code, Sections II and III, as stated in the acceptance criteria. Exceptions to the material specifications of the Code are clearly identified, and the basis evaluated. -The reviewer judges the significance of the exceptions and, taking into account precedents set in earlier cases, determines the acceptability of the
