NUREG-0800 U.S. NUCLEAR REGULATORY COMMISSION STANDARD REVIEW PLAN BRANCH TECHNICAL POSITION (BTP) 8-7 CRITERIA FOR ALARMS AND INDICATIONS ASSOCIATED WITH DIESEL-GENERATOR UNIT BYPASSED AND INOPERABLE STATUS REVIEW RESPONSIBILITIES Primary - Organization responsible for electrical engineering Secondary - None A. BACKGROUND RG 1.47 and IEEE Std. 603, as endorsed by RG 1.153, describe acceptable methods for complying with the requirements of IEEE Std. 279 with respect to indicating the bypass or inoperable status of portions of the protection system, systems actuated or controlled by the protection system, and auxiliary or supporting systems that must be operable for the protection system and the system it actuates to perform their safety-related functions. BTP 8-5 describes supplemental guidance for ESF system bypass or inoperable status indication. This BTP 8-7 provides more specific guidance on meeting the provisions of RG 1.47 as they pertain to diesel- generator units. Diesel-generator units, as reflected in RG 1.9, consist of the engine, governor, exhaust system, generator, associated excitation and voltage regulation system, combustion air system, cooling water system up to the supply, fuel supply system, lubricating oil system, starting energy sources, starting system and autostart/load features, automatic and manual controls, test features, protective trip and lockout features, local/remote control transfer features, and the diesel-generator breaker.
