Content:
ems and components of a nuclear plant. The steam and feedwater systems may be relied upon to perform safety functions such as removing decay heat or supplying steam to engineered safety feature pumps. Regulatory Guide 1.37 provides acceptable quality assurance procedures for cleaning and handling of safety-related materials. By meeting the criteria of 10 CFR 50 Appendix B and the positions of Regulatory Guide 1.37, assurance is provided that the steam and feedwater system materials are designed and selected to established Quality Assurance standards, thus providing a high degree of certainty that safety functions will be performed and the health and safety of the public will be protected. III. REVIEW PROCEDURES The reviewer will select and emphasize material from the procedures described below, as may be appropriate for a particular case. To ascertain that the acceptance criteria given in subsection II of this SRP section are met, the reviewer examines the areas listed in subsection I for the required information, in accordance with the following procedures: 1. Fracture Toughness of Class 2 and 3 Components The reviewer determines which components of the steam and feedwater systems will be made of carbon or low alloy steels, and determines that their fracture toughness properties are in conformance with subsection II.1 of this SRP section. 10.3.6-7 DRAFT Rev. 3 - April 1996 2. Materials Selection and Fabrication of Class 2 and 3 Components 34 The reviewer determines that the materials proposed for the steam and feedwater systems are in conformance with Appendix I to Section III and to parts A, B, or C of Section II of the Code. a. The reviewer determines that the methods for qualifying welders for making welds in locations of restricted direct physical and visual accessibility, and the methods for monitoring and certification of production welds in such areas are in accordance with the acceptance criteria stated in subsection II.2.b(1) of this SRP section. b.
