larm systems should be provided. These redundant systems need not comply with the single failure criterion, but independence between the redundant systems should be equivalent to that provided between redundant channels of the safety systems. See SRP Appendix 7.1-C, Subsection 5.6, “Independence.” N. Self-test provisions - See SRP BTP 7-17. The surveillance test portions of this BTP are not applicable. O. Compliance with IEEE Std 603-1991 - Alarms that are provided for manually controlled actions for which no automatic control is provided and that are required for the safety systems to accomplish their safety functions should be reviewed against the requirements of IEEE Std 603-1991. See SRP Appendix 7.1-C. This review is directed by Staff Requirements Memorandum (SRM), SECY-93-087, Item II.T, “Control Room Annunciator (Alarm) Reliability.” Recommended review emphasis for SPDS, ERF information systems, and ERDS information systems P. Independence (isolation between safety systems and other systems) - See SRP Appendix 7.1-B, Subsection 4.7, “Control and Protection System Interaction,” and SRP Appendix 7.1-C, Subsection 5.6, “Independence,” and Subsection 6.3, “Interaction Between the Sense and Command Features and Other Systems.” 2. 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. 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
