ions." One of the require- ments 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 locat- ions 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 Acces- sibilityu provides the necessary supplement to the Code, 5.2.3-11 Rev. 2 - July 1981 Section 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 1I.3.b.(4) of this SRP section. c. The ASME Code, Section III, NB-2550 specifies the ultrasonic method for examination of ferritic steel tubular products. 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, as described in Regulatory Guide 1.44. (4) For BWRs, additional processing controls, as described in NUREG-0313. In the event that information in the above areas is not supplied, sufficient justification for the deviation must be presented. b. The information submitted by the applicant is reviewed for conformance
