Content:
under 10 CFR Part 52, the procedures above should be followed, as modified by the procedures in SRP Section 14.3 (proposed), to verify that the design set forth in the standard safety analysis report, including inspections, tests, analysis, and acceptance criteria (ITAAC), site interface requirements and combined license action items, meet the acceptance criteria given in subsection II. SRP Section 14.3 (proposed) contains procedures for the review of certified design material (CDM) for the standard design, including the site parameters, interface criteria, and ITAAC.57 IV. EVALUATION FINDINGS The reviewer verifies that the SAR contains sufficient information and his that the review 58 supports the following kinds of statements and conclusions, which should be included in the staff's safety evaluation report: The staff concludes that the consequences of postulated feedwater line breaks meet the requirements set forth in the General Design Criteria 17, 27, 28, 31, and 35 regarding 59 ability to insert control rods insertability and ability to cool the core coolability,60 10 CFR Part 100 guidelines regarding radiological dose at the site boundary, and applicable TMI Action Plan Items. This conclusion is based upon the following: (a) The applicant has met the requirements of GDC 27 and 28 by demonstrating that the resultant fuel damage was minimal, ability to insert the control rod insertability would be maintained and that no loss of core cooling capability 61 resulted. The minimum departure from nucleate boiling ratio (MDNBR) experienced by any fuel rod was _______, resulting in ____% of the rods experiencing clad perforation. (b) The applicant has met the requirements of GDC 31 with respect to demonstrating the integrity of the primary system boundary to withstand the postulated accident. (c) The applicant has met the requirements of GDC 35 with respect to demonstrating the adequacy of the emergency cooling systems to provide abundant core cooling and reactivity
