or SRP Section 3.9.5.23 3. The Emergency Preparedness and Radiation Protection Branch (PERB) evaluates the plant design, including the selection of materials to minimize activation products, to verify that occupational radiation exposures will be as low as is reasonably achievable (ALARA), as part of its primary review responsibility for SRP Section 12.1.24 For those areas of review identified above as part of the review under other SRP sections, the acceptance criteria necessary for the review and their methods of application are contained in the referenced SRP sections.25 II. ACCEPTANCE CRITERIA The design, fabrication, and testing of the materials used in the reactor internals and core support structures are reviewed and evaluated to meet codes and standards commensurate with the safety functions to be performed so that the relevant requirements of Section 50.55a and General 26 DRAFT Rev. 3 - April 1996 4.5.2-4 Design Criteria 1 are met. The specific acceptance criteria necessary to meet these relevant requirements are as follows: 1. Material Specifications For core support structures and reactor internals structures, the permitted material 27 specifications are those given in the ASME Boiler and Pressure Vessel Code (Reference 6, hereafter "the Code") , Section III, Division 1 , NG-2000. These materials are 28 29 described in detail in Parts A, B, and C of Section II of the Code. Additional permitted materials and their applications are those shownidentified in ASME Code Cases approved for use byas described in Regulatory Guide 1.85., "Code Case Acceptability, ASME Section III Materials."30 2. Controls on Welding The welds of components for Methods and controls for core support structures and reactor internals welds aremust be fabricated in accordance with the Code, Section III, Division 1 , NG-4000, and the welds must meet thebe examinationed and meet 31 acceptance criteria shownas specified in NG-5000.32 3.
