ect to protection of SSC important to safety against the effects of externally generated missiles to maintain their essential safety functions. Acceptance is based on the design meeting the guidelines of Regulatory Guide 1.13, as related to the spent fuel pool systems and structures being capable of withstanding the effects of externally generated missiles and preventing missiles from contacting stored fuel assemblies; Regulatory Guide 1.27, as related to the ultimate heat sink and connecting conduits being capable of withstanding the effects of externally generated missiles; Regulatory Guide 1.115, as related to the protection of SSC important to safety from the effects of turbine missiles; and Regulatory Guide 1.117, as related to the protection of SSC important to safety from the effects of tornado missiles. III. REVIEW PROCEDURES The procedures set forth below are used during the construction permit (CP) review to determine that the applicant's list of SSC that require protection from externally generated missiles is complete and meets the acceptance cri- teria given in subsection II of this SRP section. For operating license (OL) applications, the procedures are used to verify that the CP-stage list continues to be applicable and complete, or has been supplemented as appropriate. The reviewer will select and emphasize material from the paragraphs below, as may be appropriate for a particular case. The first step in the review is to verify the identification of the safety- related SSC, and whether the SSC are considered safety related in their entirety or have only portions that are safety related. In order to determine the safety category of the SSC, the ASB evaluates the SSC of the facility with respect to their necessity for achieving and maintaining safe reactor shutdown, and for performing accident prevention or mitigation functions.
