Content:
ct to the source of water for final cleaning or flushing of finished surfaces, vented tanks with deionized or demineralized water are an acceptable source. The oxygen content of this water need not be controlled; however, the concentrations of other chemical species (e.g., chloride, fluoride) should be limited to the values listed in RG 1.44, “Control of the Processing and Use of Stainless Steel.” iii. Controls abrasive work on austenitic stainless steel surfaces in accordance with RG 1.28. iv. Follows RG 1.44. In addition to the methods discussed in RG 1.44 for verifying that austenitic stainless steel is not sensitized, alternative tests that have been previously accepted, based upon the adequacy of justifications presented and circumstances of proposed use, include the use of ASTM A-708. v. Follows RG 1.36, “Nonmetallic Thermal Insulation for Austenitic Stainless 5.4.2.1-12 Draft Revision 4 – April 2016 Steel.” The thermal insulation is acceptable if either reflective metal insulation is employed or a nonmetallic insulation that meets the criteria of RG 1.36 is used. B. Welding The joining of the materials used to fabricate a steam generator is critical to ensuring that it can properly function. Consistent with the requirements of GDC 1 and GDC 30 (for RCPB materials), the welding qualification, weld fabrication processes, and inspection during fabrication and assembly of the steam generator are performed using quality standards (supplemented and modified, as necessary) commensurate with the importance of the functions to be performed. Austenitic stainless steel welding of steam generator components is acceptable if it complies with 10 CFR Part 50, 10 CFR 50.55a(c), 10 CFR 50.55a(d), and 10 CFR 50.55a(e) and meets the following: i. RG 1.31, “Control of Ferrite Content in Stainless Steel Weld Metal” ii. RG 1.34, “Control of Electroslag Weld Properties” iii. RG 1.71, “Welder Qualification for Areas of Limited Accessibility” iv.
