Content:
usions 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, and components whose failure could prevent safe shutdown of the plant or result in significant uncontrolled release of radioactivity. Based on the review of the applicant's design bases and criteria for essential structures, systems, and components necessary to maintain a safe plant shutdown, the staff concludes that the structures, systems, and components to be protected from internally generated missiles (inside containment) meet the requirements of General Design Criterion 4 with respect to protection of safety-related SSC from internal missiles inside containment since the applicant: 1. Has used methods for identification of potential sources of internal missiles and for demonstrating the adequacy of the protection provided which have been reviewed by the staff in this or in previous applications and found acceptable; and 2. Has shown that essential SSC functions will be protected from internally generated missiles (inside containment) by locating the systems or components in individual missile- proof structures or providing special localized protective shields or barriers. V. IMPLEMENTATION The following is intended to provide guidance to applicants and licensees regarding the NRC staff's plans for using this SRP section. Except in those cases in which the applicant proposes an acceptable alter- native method for complying with specified portions of the Commission's regu- lations, the method described herein will be used by the staff in its evalua- tion of conformance with Commission regulations.
