n II.3.b.(2) of this SRP section. 5.2.3-17 DRAFT Rev. 3 - April 1996 (3) The ASME Code, Section III, requires adherence to the requirements of Section IX, "Welding Qualifications." of the Code. One of the 96 requirements is welder qualification for production welds. However, there is a need for supplementing this section of the Code because the assurance of providing satisfactory welds in locations of restricted direct physical and visual accessibility can be increased significantly by qualifying the welder under conditions simulating the space limitations under which the actual welds will be made. Regulatory Guide 1.71, "Welder Qualification for Limited Accessibility," provides the necessary supplement to the Code, Section 97 IX, in this respect. The information submitted by the applicant is reviewed for conformance with acceptance criteria discussed in subsection II.3.b.(3) of this SRP section. (4) The information submitted by the applicant regarding controls to limit the occurrence of underclad cracking in low alloy steel components when weld cladding with austenitic stainless steel are reviewed for conformance with acceptance criteria given in subsection II.3.b.(4) of this SRP section. c. The reviewer verifies that acceptable methods specified in the ASME Code, Section III, paragraphs NB-2550 through NB-2570 specifies the ultrasonic acceptable method are proposed by the applicant for examination of ferritic steel tubular products . 98 4. Fabrication and Processing of Austenitic Stainless Steels a. The information submitted by the applicant in the following areas is reviewed for conformance with the acceptance criteria stated in subsection II.4.a of this SRP section regarding: (1) The desirable stage in the sequence of processing for solution heat treatment, the rates of cooling, and the quenching media. (2) Controls to prevent sensitization during welding, as described in Regulatory Guide 1.44. (3) Controls to verify non-sensitization, and to qualify welding
