CALLAWAY - UNIT 1 B 3/4 8-1 Amendment No. 21
INSERT 1 Each diesel generator (DG) is provided with an engine overspeed
-ip to prevent damage to the engine.
Recovery from the r c: ient caused by the loss of a large load could cause d'.m-engine overspeed, which, if excessive, might cult i..
trip of the engine.
Surveillance 4. 8.1.1. 2. f. ( 2 ) demonstrates the DG load response characteristics and capability to reject the largest single load without exceeding predetermined voltage and frequency and while maintain! g a specified margin to the overspeed trip as required by Regulatory Guide 1.9, Position C.4.
