ESF ACTUATION - SAFETY INJECTION SIGNAL INADVERTENTLY INSERTED DURING TESTING

While performing post maintenance testing on 1P-ISA (Safety Injection Pump), an inadvertent ESF occurred. The 'A' Safety Injection Train actuated on Unit 1 after the electrician installed a jumper which was intended to simulate an Auto Start signal for 1P-ISA. The jumper terminals appear to have been incorrectly identified in the work plan. All systems started as designed. The SI pumps did not start because they were in pull-to-lock per procedure for the existing plant conditions. The following components/activations occurred: Aux feed pump start, EDG start (Train A), and containment isolation. Because the affected unit was defueled, systems that would normally inject into the reactor coolant system were tagged out. There was no ECCS discharge. Service water was momentarily isolated to Spent Fuel Pool Cooling resulting in spent fuel pool temperature increasing slightly. Bulk spent fuel pool temperature remained at approximately 85°F. Current calculated time to boil is 19 hours.

The licensee notified the NRC resident inspector.
