imilar ferritic products in subsection III.3.c of this SRP section, and the acceptance criteria are as shown in subsection II.4.e of this SRP section. f. Cast austenitic stainless steel is susceptible to thermal aging at reactor coolant temperatures (Reference 20). The reviewer verifies that the applicant has considered alternative materials to cast stainless steels and has limited use of cast stainless steel in the RCPB to those specific applications where demonstrated to be the best material selection alternative. Where cast material is used, the range of temperatures to which the material will be exposed and the ferrite content of the material receive particular review emphasis. The reviewer verifies that the applicant's proposed material specifications and fabrication controls ensure adequate fracture toughness over the design life of the plant. Where cast austenitic stainless steel components with welded joints requiring preservice and inservice inspection are proposed, the reviewer confirms the feasibility of required inspections using ultrasonic techniques.107 DRAFT Rev. 3 - April 1996 5.2.3-20 5. General If the information contained in the safety analysis reports or the plant Technical Specifications does not comply with the appropriate acceptance criteria, or if the information provided is inadequate to establish such compliance, a request for additional information is prepared and transmitted. Such requests identify not only the necessary additional information but also the changes needed in the SAR or the Technical Specifications. Subsequent amendments received in response to these requests are reviewed for compliance with the applicable acceptance criteria. For design certification reviews, the findings will also summarize, to the extent that the review is not discussed in other safety evaluation report sections, the staff’s evaluation of inspections, tests, analyses, and acceptance criteria (ITAAC), including design acceptance criteria (DAC), site
