CFR Title: 

Content:
ure boundary shall be designed with sufficient margin to assure that when stressed under operating, maintenance, testing, and postulated accident conditions, a.(1) the boundary behaves in a nonbrittle manner, and b.(2) the probability 22 of rapidly propagating fracture is minimized. 5. Appendix B, 10 CFR Part 50 - "Quality Assurance Criteria for Nuclear Power Plants and Fuel Reprocessing Plants.," Criterion XIII, "Handling, Storage and Shipping"23 This regulation states that measures shall be established to control the cleaning of 24 material and equipment in accordance with work and inspection procedures to prevent damage or deterioration. Specific criteria necessary to meet the relevant requirements of the Commission regulations identified above are: A. Primary Materials Review Criteria 25 1. Selection and Fabrication of Materials a. To meet the requirements of GDC 1, the acceptable materials for steam generator components are those identified and permitted in the ASME Code, Appendix I of Section III, and specified in detail in the Code Parts A, B, and C of Section II. Any materials specified in the design to meet code-case requirements must also meet the requirements givenshould conform with the guidance for acceptable code-cases and use thereof described in Regulatory Guide 1.85, "Materials Code Case Acceptability 26 ASME Section III Division I-Materials." Any materials selected for the 27 tube support structure should be justified on the basis of minimizing the denting and corrosion of the tubes. b. To meet the requirements of GDC 1, 14, and 31, the fracture toughness of ferritic materials used for Class 1 components in the steam generator must DRAFT Rev. 3 - April 1996 5.4.2.1-6 meet the requirements of Appendix G of 10 CFR Part 50, as augmented by Subarticle NB-2300, Section III of the Code and Appendix G, Article G-2000 of the Code. The fracture toughness properties of the ferritic materials selected for Class 2 components in the steam generator must meet
