BACKGROUND Regulatory Guide 1.47, "Bypassed and Inoperable Status Indication for Nuclear Power Plant Safety Systems," and IEEE Std 603 (Reference 7), as endorsed by Regulatory Guide 1.153, 47 describes an acceptable methods for complying with the requirements of IEEE 279, "Criteria 48 for Protection Systems for Nuclear Power Generating Stations," (Reference 6) with respect to 49 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. Branch Technical Position ICSB-21 (Reference 4) describes supplemental guidance for engineered safety features system bypass or inoperable status indication. This Branch Technical Position (PSB-2) describesThis appendix gives more specific guidance on meeting the 50 provisions of Regulatory Guide 1.47 as they pertain to diesel-generator units. Diesel-generator units, as defined in Regulatory Guide 1.108, "Periodic Testing of Diesel Generator Units Used as Onsite Electric Power Systems at Nuclear Power Plants," as reflected in Regulatory Guide 1.9,51 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
