hould describe the important system alarms, displays (do not use the term "indications"), and controls available in the control room. Important instrumentation that is required for direct operation or accident mitigation should be shown on the system figure, or described in the DD if there is no figure. Those that are provided for routine system performance monitoring or operator convenience need not be shown or discussed. The Generic Technical Guidelines (e.g., ERGs, EPGs) in DCD Tier 2 Chapter 18 should have identified the minimum set of controls, displays, and alarms necessary for the main control room (MCR) and remote shutdown panel (RSP), and these should be included in Tier 1. The functioning of the alarms, displays, and controls in the MCR and RSP should be verified in either the system ITAACs or in the MCR/RSP ITAACs. The intent is to test the integrated as-built system; however, separate testing of the actual operation of the system and the alarms/displays/controls circuits using simulated signals may be acceptable where this is not practical. See also the standard ITAAC for control room features and the remote shutdown panel in Appendix C to this SRP section. vii. Logic. If a system/component has a direct safety function, it typically receives automatic signals to perform some action. This includes start, isolation, etc. The DD captures these aspects related to the direct safety function of the system. viii. Interlocks. Interlocks needed for direct safety functions should be included in the system DD. Examples include the interlocks to prevent ISLOCA and an interlock that switches the system or component from one mode to a safety function mode. Other interlocks that are more equipment protective in nature, are only included in the DCD Tier 2. ix. Class 1E electrical power sources/divisions. The DD or figure should identify the electrical power source/division for the equipment included in the system. Independent Class 1E power sources are required for
