Content:
e Content in Stain- less Steel Weld Metal," describes acceptable criteria for assuring the integrity of welds in austenitic stainless steel ESF components. The control of delta ferrite content of weld filler metal is specified in this guide, which sets forth an acceptable basis for delta ferrite content of weld filler metal. 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 used: 1. The amount of minimum specified preheat must be in accord- ance with the 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. 2. Moisture control on low hydrogen welding materials shall conform to the requirements of the Code, Section III, Arti- cles NB, NC, ND-2000 and 4000, and AWS D1.1, "Structural Welding Code," unless alternate procedures are justified. 3. For areas of limited accessibility, the criteria of SRP Section 10.3.6, subsection II.2.c shall apply. B. Criteria for Secondary Review Areas 1. Composition and Compatibility of Engineered Safety Feature Fluids In meeting the requirements of General Design Criteria 4 and 41, that structures, systems, and components important to safety are designed to accommodate the effects of and to be compatible with 6.1.1-5 Rev. 2 - July 1981 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 following postulated accidents is controlled to maintain containment integrity, the hydrogen generation resulting from the corrosion of metals by
