e used on austenitic stainless steel surfaces.49 b. Ferritic Steel Welding To meet the requirements of General Design Criterion 1 related to general quality assurance and Codes and Standards, Appendix B to 10 CFR Part 50, related to control of special processes; and 10 CFR Part 50, §50.55a, "Codes and Standards," the following acceptance criteria for ferritic steel welding should be 50 used: (1.) The amount of minimum specified preheat must be in accordance with the 51 recommendations of the Code, Section III, Appendix D, Article D-1000, and Regulatory Guide 1.50, "Control of Preheat Temperature for Welding Low-Alloy Steel," unless an alternate procedure is justified. 52 (2.) Moisture control on low hydrogen welding materials shall conform to the requirements of the Code, Section III, Articles NB, NC, ND-2000 and 4000, and AWS D1.1 (Reference 21), "Structural Welding Code," unless 53 alternate procedures are justified. With respect to criteria b(1) and b(2) above, acceptable alternate procedures for ferritic steel welding are identified in SRP Section 5.2.3, subsection II.3.b.54 (3.) For areas of limited accessibility, the criteria of SRP Section 10.3.6, subsection II.2.cb shall apply.55 B. Criteria for Secondary Review Areas56 12. Composition and Compatibility of Engineered Safety Feature Fluids 57 In meeting the requirements of General Design Criteria 4 and 41, that structures, systems, and components SSCs important to safety are designed to accommodate the effects of 58 and to be compatible with environmental conditions associated with normal operation, maintenance, testing and postulated accident conditions, including loss-of-coolant accidents and to assure that the concentration of hydrogen in the containment atmosphere DRAFT Rev. 2 - April 1996 6.1.1-8 following postulated accidents is controlled to maintain containment integrity, the hydrogen generation resulting from the corrosion of metals by the containment sprays during design basis accident should be
