parate licensing topical report and frequently handled outside the scope of the review for a particular facility). c. Perform auditing-type calculations with methods available to the staff. d. Require additional bounding calculations by the applicant to cover portions of the applicant's analytical methods that are not fully reviewed or approved. 5. For new application reviews, the analysis must consider a loss of offsite power in conjunction with the limiting single active failure when assessing the consequences of the anticipated operational occurrence. (This position is based upon interpretation of GDC 17, as documented in the Final Safety Evaluation Report for the ABB-CE System 80+ design certification.)30 65. The significant results of the analysis should be presented and should include maximum power levels reached for the reactor and the peak fuel rod, scram or rod block actions that occur, reactor temperatures and pressures, maximum heat flux levels, and the related fuel duty (operating conditions and performance). The latter are compared with the acceptance criteria in subsection II of this SRP section.31 For standard design certification reviews 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.32 IV. EVALUATION FINDINGS If on completion of the review the staff finds the applicant's analysis acceptable, conclusions of the following type should be included in the staff's safety evaluation report: 1. The possibilities for single failures of the
