On September 27, 2003, at 1544 hours Easte … On September 27, 2003, at 1544 hours Eastern Daylight Savings Time, while In a refueling outage, R.E. Ginna Nuclear Station experienced a momentary invalid partial Safety Injection (SI) signal to the "A" train. The invalid signal was the result of an error made while placing a jumper across a relay during a 24 month surveillance. The invalid partial SI signal caused the following systems to actuate: "A " train Containment Ventilation Isolation (CVI), "A" train Diesel Generator (DG), trip of MCC G1, full opening of Service Water (SW) AOV-4561 to the containment recirculation fans, and the opening of Residual Heat Removal (RHR) core deluge valve MOV-852A. Each individual actuation was complete, the "A" DG started and functioned as designed, and all support systems functioned properly. The individual slave timers fed from the SI relay did not actuate. The most probable cause of this was the momentary nature of the partial SI signal.</br>The licensee informed the NRC Resident Inspector.ensee informed the NRC Resident Inspector. +
