for performing safety functions satisfy the requirements of Item II.Q of the Staff Requirements Memorandum on SECY-93-087. The Staff confirmed that the consequential effects of anticipated operational occurrences and accidents do not result in control system failures that would cause plant conditions more severe than those bounded by the analysis of the events. The conclusions of the analysis of anticipated operational occurrences and accidents as presented in Chapter 15 of the SAR have been used to confirm that plant safety is not dependent upon the response of the control systems. The Staff also confirmed that failure of the control systems themselves or as a consequence of supporting system failures, such as loss of power sources, does not result in plant conditions more severe than those described in the analysis of design basis accidents and anticipated operational occurrences. Note: the following findings apply only to applications under 10 CFR 52. The control systems design appropriately addresses the applicable unresolved and generic safety issues. Therefore, the Staff finds that the control systems satisfy the requirements of 10 CFR 52.47(a)(1)(iv). The review of the control systems examined the proposed inspections, tests, analyses, and acceptance criteria (ITAAC). Based upon the review and coordination with those having primary responsibility for ITAAC, the Staff concludes that if the inspections, tests, and analyses are performed and the acceptance criteria met, the plant will operate in accordance with the [design certification OR combined license]. Therefore, the Staff finds that the control systems satisfy the requirements of [10 CFR 52.47(a)(1)(vi) OR 10 CFR 52.79(c)]. The application for design certification does not seek certification for the following portions of the control system [insert list]. Based upon review of the completed safety analysis, the Staff finds that the requirements for these portions of the design were sufficiently detailed.
