Content:
instrumentation, (4) acceptability of test results, and (5) documentation of weld pad verification tests . For the BWR 86 austenitic stainless steel RCPB piping specified in Generic Letter 88-01, the weld metal ferrite content should be controlled as described in the positions of Attachment A to Generic Letter 88-01 or the recommendations of NUREG- 0313.87 The acceptance criteria for electroslag welds in austenitic stainless steel are given in Regulatory Guide 1.34, "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: 88 (1) The performance qualification should require testing of the welder when conditions of accessibility to a production weld 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. 5.2.3-13 DRAFT Rev. 3 - April 1996 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, Paragraphs NB-2550 through NB- 2570. (Item II.4.e. is applicable to material reviewed by MTEB as specified in 89 item I.4.e.)90 Technical Rationale:91 The technical rationale for application of the above acceptance criteria to the RCPB materials is discussed in the following paragraphs: 1. GDC 1 and 10 CFR 50.55a require that structures, systems, and components (SSCs) be designed,
