, processing techniques, categorization of the IGSCC resistance of installations based upon material properties, treatment history, and post-weld treatments. The technical bases for these controls are described in NUREG- 0313.80 DRAFT Rev. 3 - April 1996 5.2.3-12 c. The acceptance criteria for compatibility of austenitic stainless steel with thermal insulation are based on Regulatory Guide 1.36, "Nonmetallic Thermal Insulation for Austenitic Stainless Steel," to satisfy GDC 14 and 31 relative to prevention 81 of failure of the RCPB. The compatibility of austenitic stainless steel materials with thermal insulation is dependent upon the type of insulation. The thermal insulation is acceptable if either reflective metal insulation is employed or a nonmetallic insulation which meets the criteria of Regulatory Guide 1.36, "Nonmetallic Thermal Insulation for Austenitic Stainless Steel," is used. The 82 acceptance criteria for nonmetallic insulation for stainless steel are based on the levels of leachable contaminants in the material and are presented in position C.2.b and Figure 1 of the guide. (Applicable to material reviewed by CMEB in item I.4.c.)83 d. The acceptance criteria for control of welding of austenitic stainless steels are based on NUREG-0313 as described below and on Regulatory Guides 1.31, 84 1.34, and 1.71, to satisfy the quality standards requirements of GDC 1, GDC 30, and §50.55a. (Item II.4.d is applicable to material reviewed by MTEB as specified in item I.4.d.)85 The acceptance criteria for delta ferrite in austenitic stainless steel welds are given in Regulatory Guide 1.31, "Control of Ferrite Content in Stainless Steel Weld Metal." These acceptance criteria cover (1) verification of delta ferrite content of filler metals, (2) ferrite measurement, (3) 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
