components and the effects of adverse environmental occurrences, abnormal operational requirements, or accident conditions such as those due to a loss-of-coolant accident (LOCA). 2. The determination that a malfunction, a single failure of an active component, or the loss of a cooling source will not reduce the safety-related functional performance capabilities of the system. 3. That quality group and seismic design requirements are met and the effects of failure of equipment or components not designed to withstand seismic events on safety-related functions of the system are evaluated. 4. The system features provided to prevent precipitation of boric acid in components and lines containing boric acid solutions, and the adequacy of the system design to protect personnel from the effects of toxic, irritating, or explosive chemicals that may be used. 5. Provisions for operational testing and the instrumentation and control features that determine and verify that the system is operating in the correct mode. 6. The system provisions to prevent the formation of vacuum conditions in tanks that can contain primary system water.5 B. The review for fire protection is performed by CMEB in SRP Section 9.5.1.6 Review Interfaces:7 Coordinated reviews that interface with the overall review of the CVCS by CMEB are performed by other branches as follows. The EMCB will coordinate with other branches' evaluations and reviews that interface with the overall review of the system as follows:8 1. The Plant Systems Branch (SPLB) performs the following reviews: a. The ASB SPLB also evaluates the capability of the CVCS to withstand external 9 and internal flood conditions as part of its primary review responsibility for SRP Sections 3.4.1 and 9.3.3. b. The ASB SPLB also evaluates the capability of internally generated missiles 10 both inside and outside primary containment as part of its primary review responsibility for SRP Sections 3.5.1.1 and 3.5.1.2. c. The ASB SPLB also evaluates the
