ovals (e.g., manufacturing license, site suitability report or topical report). 15.8-12 Revision 2 - March 2007 IV. EVALUATION FINDINGS The reviewer verifies that the applicant has provided sufficient information and that the review and calculations (if applicable) support conclusions of the following type to be included in the staff's safety evaluation report. The reviewer also states the bases for those conclusions. The staff concludes that the plant design adequately addresses ATWS events and meets the requirements of 10 CFR 50.62. This conclusion is based on the following: 1. The applicant’s plant design includes the ATWS risk reduction features prescribed by the Rule. 2. These features are independent and diverse from the reactor trip system and are designed to be reliable, as required under the Rule. 3. The applicant has also provided or referenced information, analyses, and/or evaluations that demonstrate that limiting ATWS and event sequences have been considered and that features included in the design pursuant to the Rule result in reasonable assurance, that unacceptable plant conditions, as defined during the Rulemaking, will not occur because of ATWS events. For evolutionary designs/plants that are not explicitly required to provide a diverse scram system under the Rule, the reviewer should state the finding from the two below that applies: 1. The applicant has also provided an acceptable diverse scram system. 2. The applicant has demonstrated acceptable consequences for ATWS events without credit for a diverse scram system. For DC and COL reviews, the findings will also summarize the staff’s evaluation of requirements and restrictions (e.g., interface requirements and site parameters) and COL action items relevant to this SRP section. V. IMPLEMENTATION The staff will use this SRP section in performing safety evaluations of DC applications and license applications submitted by applicants pursuant to 10 CFR Part 50 or 10 CFR Part 52.
