Nature of Defect, Substantial Safety Hazard Created, and Evaluation The diesel generators are required to start from normal ambient standby condition and be ready for loading in less than or equal to 10 seconds. This starting time is required to provide power to components of the Engineered Safety Features System.
After several days without operation, the diesel starting time is greater than 10 seconds with subsequent starts less than 10 seconds. Problem is attributed to fuel oil header drain down.
