REVIEW RESPONSIBILITIES Primary - Materials Engineering Branch (MTEB)Materials and Chemical Engineering Branch (EMCB)1 Secondary - None I. AREAS OF REVIEW Section 50.55a, "Codes and Standards," and General Design Criterion 1, Appendix A, 10 CFR Part 50 requires that structures, systems, and components (SSCs) important to safety shall be 2 designed, fabricated, and tested to quality standards commensurate with the importance of the safety function to be performed. The purpose of this SRP section is to review and evaluate the adequacy of the materials selected for the construction of the reactor internals and core support structures, and to assure that these regulations are met for those structures and components. The 3 reactor internals and core support structures reviewed under this SRP section areinclude all structures and components within the pressure vessel other than the fuel and control assemblies, and instrumentation.4 The Materials Engineering Branch (MTEB)EMCB reviews the materials specifications, 5 6 component design, fabrication and inspection to assure structural integrity in compliance with Section 50.55a and General Design Criterion 1 of 10 CFR Part 50. The Chemical Engineering Branch (CMEB) reviews areas of corrosion and compatibility of these materials with the expected environment during service as part of its primary review responsibility of SRP Section 5.2.3.7 DRAFT Rev. 3 - April 1996 4.5.2-2 The following areas in the applicant's safety analysis report (SAR) relating to reactor internal and core support materials are reviewed: 1. Material Specifications The review includes the specifications for the materials, including weld materials, to be used for major components of the reactor internals which consist ofand the core support structures and the internal structures. The reactor internal and core support structures 8 are all structures and components within the pressure vessel other than the fuel and control assemblies, and instrumentation.9 The
