Content:
1. The review should confirm that the control systems satisfy the requirements of the acceptance criteria and the system design bases. 2. The review should confirm that the plant accident analysis in Chapter 15 of the SAR does not rely on the operability control systems to assure safety. 3. The review should confirm that the safety analysis includes consideration of the effects of both control systems action and inaction in assessing the transient response of the plant for accidents and anticipated operational occurrences. 4. The review should confirm that the consequential effects of anticipated operational occurrences and accidents do not lead to control systems failures which would result in consequences more severe than those bounded by the analysis in Chapter 15 of the SAR. 5. The review should confirm that the failure of any control system component or any auxiliary supporting system for control systems do not cause plant conditions more severe than those bounded by the analysis of anticipated operational occurrences in Chapter 15 of the SAR. (The evaluation of multiple independent failures is not intended.) 6. The review should confirm that the environmental control system has been designed to meet the guidelines of RG 1.151, position 5 so that adequate protection from extreme cold weather has been provided. In certain instances, it will be the reviewer's judgment that for a specific case under review, emphasis should be placed on specific aspects of the design, while other aspects of the design need not receive the same emphasis and indepth review. Typical reasons for such a nonuniform placement of emphasis are the introduction of new design features or the utilization in the design of design features previously reviewed and found acceptable. However, in all cases, the review must be sufficient to conclude conformance to the acceptance criteria, i.e., the requirements of the Commission's regulations. IV. EVALUATION FINDINGS The reviewer confirms that
