3.5.1.5 SITE PROXIMITY MISSILES (EXCEPT AIRCRAFT) REVIEW RESPONSIBILITIES Primary- Siting Analysis Branch (SAB) Secondary- NONE

The staff reviews the nature and extent of offsite activities identified in SRP Section 2.2.1-2.2.2 to determine whether any missiles resulting from such activities, other than aircraft (aircraft hazards are reviewed separately in SRP Section 3.5.1.6), have the potential for adversely affecting structures, systems, and components (SSC) essential to safety. In the event that an offsite activity has the potential for missile production (e.g., explosion) and is found to be a design basis event accord-ing to SRP Section 2.2.3, the staff reviews the plant design to determine whether the plant is adequately protected against the effects of the postulated missiles. The SSC that should be protected against missiles are identified in accordance with SRP Section 3.5.2 as part of the primary review responsibility of the Auxiliary Systems Branch (ASB).. The Siting Analysis Branch (SAB) identifies and characterizes any offsite missiles that are required to be accommodated within the plant design basis in order to protect adequately the safety-related SSC. The Structural Engi-neering Branch (SEB) on request by SAB reviews the missile impact effects on the safety-related SSC. The acceptance criteria necessary for the review and the methods of application for the above reviews are contained in the referenced SRP section. II. ACCEPTANCE CRITERIA SAB acceptance criteria are based on meeting the relevant requirements of one of the 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 radiologica
