in the review of the structures, systems, and components, with regard to protection requirements for internally generated missiles, is to determine whether the equipment is needed to perform a safety function. Some structures and systems are designed as safety related in their .entirety, others have portions that are safety related, and others are classified as not needed for safety. In order to determine the safety category of the SSC, the RSB and CSB upon request from the ASB, will evaluate the SSC with regard to their function in achieving safe reactor shutdown conditions or in preventing accidents or mitigating the consequences of accidents, and will provide an input to the ASB. The primary reviewer obtains such input as required to assure that this review procedure is complete. Structures, systems, or components that perform a safety function, or by virtue of their failure could have an adverse effect on a safety function should be protected from the effects of internally generated-missiles. 3.5.1.2-2 Rev. 2 - July 1981 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 SSC as a result of missile impingement and missile 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, ahd components require protection from internally generated missiles and whether the degree of protection provided is adequate. IV. EVALUATION FINDINGS The reviewer verifies that sufficient information has been provided and that his evaluation supports conclusions of the following type, to be included in the staff's safety evaluation report: The review of possible effects of internally generated missiles (inside containment) included structures, systems,
