uld be stated or provided in such a way as to facilitate the establishment of verification criteria, and the performance of analyses and reviews of the various protection systems. In addition to these characteristics, the following should be noted about the parts of IEEE Std. 279-1971 Clause 3. Clause 3(1) of IEEE Std. 279-1971 requires in part the identification of conditions that require protective action. This information should be consistent with the analysis provided in Chapter 15 of the SAR. SRP Branch Technical Position (BTP) 7-4 provides specific guidance on the failures and malfunctions that should be considered in identification of design basis events for systems that initiate and control auxiliary feedwater systems. SRP BTP 7-5 provides specific guidance on the reactivity control malfunctions that should be considered in the identification of conditions requiring protective action. The malfunctions assumed should be consistent with the control system failure modes described in Section 7.7 of the SAR and the reactivity control interlock functions described in Section 7.6 of the SAR.
