Content:
s on SSC important to safety must be evaluated. Regulatory Guide 1.117 provides acceptable methods for determining those SSC that should be protected. Protecting those SSC important to safety from the effects of externally generated missiles due to aircraft hazards prevents failure of those systems required for safe shutdown and prevents the release of radioactivity with the potential for causing exposures in excess of the 10 CFR Part 100 guidelines. 3. GDC 3 establishes requirements regarding minimizing the probability and effect of fires and explosions on SSC important to safety. Aircraft hazards include the potential through an aircraft impact for fires and explosions that could effect SSC important to safety. Regulatory Guide 1.117 describes a method acceptable to the NRC staff for determining which SSC should be protected. The selection of SSC to be protected is based upon not allowing offsite exposures to exceed an appropriate fraction of the offsite dose guidelines of 10 CFR Part 100. Basing the limits upon an appropriate "fraction" ensures protection for those events that are not as severe as the design-basis event but have a higher probability of occurrence. Protecting those SSC that are important to safety from the effects of aircraft hazards ensures the capability to shutdown the reactor and maintain it in a shutdown condition and the capability to prevent the release of radioactivity with the potential for causing exposures in excess of the 10 CFR Part 100 guidelines. 3.5.1.6-5 DRAFT Rev. 3 - April 1996 III. REVIEW PROCEDURES The reviewer selects and emphasizes aspects of the areas covered by this SRP section as may be appropriate for a particular case. The judgment on areas to be given attention and emphasis in the review is based on a inspection of the material presented to see whether it is similar to that recently reviewed on other plants and whether items of special safety significantce are 35 involved. The staff's review of the aircraft hazard
