elated functions. The reviewer may use failure mode and effect analyses and the results of reviews by other branches in evaluating SSCs to identify those requiring protection from internally-generated missiles, the origins of possible missiles, and the adequacy of the protection. 3. The reviewer determines whether nonsafety-related SSCs are protected from internally-generated missiles by whether their failure by a missile impact could prevent an SSC required safety function. 4. The reviewer determines whether the applicant’s procedures, analysis, and design details ensure that pressurized gas bottles will not become missiles capable of damaging SSCs important to safety to the extent that safety-related functions are compromised. The storage and handling of compressed gases at nuclear power plants was studied by Oak Ridge National Laboratory for potential safety hazards. The results of these studies are documented in NUREG/CR-3551. 3.5.1.1-6 Revision 3 - March 2007 5. For applicants referencing a certified design, the reviewer determines whether adequate protection is included in the design details for pressurized gas bottles and in the details of missile protection features for SSCs or is outside the scope of the DC. 6. For review of a DC application, the reviewer should follow the above procedures to verify that the design, including requirements and restrictions (e.g., interface requirements and site parameters), set forth in the final safety analysis report (FSAR) meets the acceptance criteria. DCs have referred to the FSAR as the design control document (DCD). The reviewer should also consider the appropriateness of identified COL action items. The reviewer may identify additional COL action items; however, to ensure these COL action items are addressed during a COL application, they should be added to the DC FSAR. For review of a COL application, the scope of the review is dependent on whether the COL applicant references a DC, an early site permit (ESP) or
