Event Text

MANUAL SCRAM DUE TO LOSS OF TACS

"Hope Creek was manually scrammed due to a complete and sustained loss of TACS (Turbine Auxiliary Cooling System). Turbine Auxiliary cooling supplies cooling water to the main generator. A loss of cooling to the main generator resulted in a turbine and reactor recirculation pump runback. The unit was removed from service in accordance with station procedures. TACS was subsequently restored post scram.

"The cause of TACS loss is under investigation. All control rods are inserted and the reactor is shutdown. All safety systems responded as required. Plant is currently stable with pressure control 800 - 1000 psi (automatic pressure control set at 880 psi) on turbine bypass valves. Level band 12.5" - 54" (level 3 - level 8) (automatic level control set at 25") feeding with 'A' RFPT in startup level control. Decay Heat removal is being maintained by the main condenser through the turbine bypass valves. No personnel injuries occurred. The plant will be maintained in the current condition while troubleshooting the cause of the loss of TACS."
