criteria necessary for the review and their methods of application for the above reviews are contained in the referenced SRP sections. 12 II. ACCEPTANCE CRITERIA SABSPLB acceptance criteria are based on meeting the relevant requirements of one of the 13 following regulations: 1. 10 CFR Part 100, §100.10 indicates that the site location, in conjunction with other considerations (such as plant design, construction, and operation), should insure a low risk of public exposure. This requirement is met if the probability of site proximity missiles impacting the plant and causing radiological consequences greater than 10 CFR Part 100 exposure guidelines is less than about 10 per year (see SRP Section 2.2.3). If the results of -7 the review do not indicate that the above criterion is met, then the acceptance criterion described in 2 below applies. 2. General Design Criterion (GDC) 4 of 10 CFR Part 50, Appendix A, requires that structures, systems, and components (SSC) important to safety be appropriately protected against the 14 effects of missiles that may result from events and conditions outside the nuclear power unit. The plant complies with GDC 4 and is considered adequately protected against site proximity missiles if the following criterion is met: The SSC important to safety are capable of withstanding the effects of the postulated missiles without loss of safe shutdown capability and without causing a release of radioactivity which would exceed 10 CFR Part 100 dose criteria. Technical Rationale:15 The technical rationale for application of the above acceptance criteria to site proximity missiles (except aircraft) is discussed in the following paragraphs. 1. 10 CFR Part 100, §100.10 establishes site requirements in conjunction with other design features regarding ensuring a low risk of public exposure. A probability of less than 10 per -7 year has been established as an NRC staff objective for meeting the requirements of 10 CFR Part 100. In regard to missiles
