g safe reactor shutdown conditions and preventing significant uncontrolled release of radioactivity or in preventing accidents or mitigating the consequences of accidents, 26 and will provide an input to the ASBSPLB . The primary reviewer obtains such input as 27 required to assure that this review procedure is complete. Structures, systems, or 28 componentsSSC that perform a safety function, or by virtue of their failure could have an 29 adverse effect on a safety function should be protected from the effects of internally generated missiles. DRAFT Rev. 3 - April 1996 3.5.1.2-4 A review is conducted of the information provided in the SAR pertaining to SSC design bases and criteria, the listing of credible primary missiles, secondary missiles, damage or failures to safety-related SSCSSC important to safety as a result of missile impingement and missile 30 protection provided. The reviewer may use failure mode and effect analyses and the results of other portions of the facility review in evaluating specific SSC and the origin of possible missiles, and in determining which structures, systems, and componentsSSC require protection 31 from internally generated missiles and whether the degree of protection provided is adequate. The missile protection provided for SSC important to safety is adequate if the protection is provided by one or more of the following: (1) locating the system or component in a missile-proof structure, (2) separating redundant systems or components for the missile path or range, (3) providing local shields and barriers for systems and components, (4) designing the equipment to withstand the impact of the most damaging missile, (5) providing design features to prevent the generation of missiles, (6) orienting missile sources to prevent missiles from striking equipment important to safety.32 The reviewer determines that controls are provided to ensure that unsecured maintenance equipment, including equipment required for maintenance and equipment
