1. Manually-initiated start of the diesel generator, followed by manual synchronization with other power sources and assumption of load by the diesel generator shall not exceed 2850KW. This test will be conducted monthly with a minimum running time of 30 minutes on each diesel generator. Normal plant operation will :,ot be affected.
2. Automatic start of each diesel generator, load shedding, and restor-ation to operatio:. of particular vital equipment, initiated by an actual interruption of normal AC station service power supplies to associated engineered safety systems busses together with a simulated safety injection signal. In addition, af ter the diesel generator has carried its load for a minimum of 5 minutes, automatic load shedding and restoration of vital loads are tested again by manually tripping the diesel generator output breaker., This test will'be~ conducted during reactor shutdown for major' fuel reloading of iach reactor to assure that the_ diesel generator will(stert and assume _ required load in'accordance with the timing' sequence listed.in FSAR Section~8;-
