Title | Invalid Safety Injection Signal During Surveillance Testing at Ginna |
Event Description | {{#Wiki_filter:On October 8, 2003, at 0216 hours Eastern Daylight Savings Time, while in a refueling outage, R.E. Ginna Nuclear Station experienced an invalid "B" train Safety Injection (SI) signal. The invalid signal was the result of an error made while establishing pretest requirements during a 24 month surveillance. The invalid SI signal caused the �B" train Diesel Generator (DG) to actuate. The "B" DG started and functioned as designed, and all support systems functioned properly."
The licensee informed the NRC Resident Inspector. }} |
