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. For CP, OL, DC and COL reviews, a conclusion of one of the following types may be prepared for the staff’s safety evaluation report: 1. The staff concludes that the protection for SSCs important to safety is acceptable and meets the requirements of GDC 4. This conclusion is based on the information provided by the applicant and reviewed by the staff which identified potential missiles that could adversely affect safety-related SSCs requiring protection from externally generated missiles and which demonstrates that these SSCs have adequate barriers protecting them from the effects of missiles such that radiation exposures in excess of those given in 10 CFR Part 100 will not be exceeded. 2. Information provided by the applicant and reviewed by the staff has led to the identification of potential missiles that could adversely affect safety-related SSCs important to safety which warrant detailed evaluation of their protection against such externally generated missiles. However, some of these SSCs have adequate barriers protecting them from the effects of such missiles in accordance with the requirements of GDC 4 such that radiation exposures in excess of the limits given in 10 CFR Part 100 will not be exceeded. The remaining safety-related SSCs, although vulnerable to the potential effects of identified missiles, have a sufficiently low probability (within the criteria given in SRP Section 2.2.3) of unacceptable damage (on the basis of considerations such as low strike probability or adequate separation and redundancy) such that the risk of public exposure is low and the design meets the requirements of 10 CFR 100.20. For DC and COL reviews, the findings will
