A fuel assembly was accidentally dropped into the unit's spent fuel pool, contributed to the delay.
Fuel vendor ABB-Combustion Engineering inspected the dropped fuel assembly and found no damage. The assembly was dropped as it was being lifted out of temporary storage in the spent fuel pool. As the fuel handling tool lifted it, the assembly fell about two feet, coming to rest sitting on top of the pool rack and propped up against the pool's wall at about a 45 degree angle. It was lifted out, put into a cask and shipped to ABB-CE for further inspection.

ALERT DECLARED DUE TO AN AMMONIA RELEASE AT A CHEMICAL FACILITY
NEAR THE PLANT. KOCH INDUSTRIES, WHICH IS LOCATED APPROXIMATELY 0.8 MILES EAST OF WATERFORD, HAD AN AMMONIA RELEASE. THE RELEASE IS CHARACTERIZED AS A SMALL RELEASE AND IS DUE TO THE FLAME THAT NORMALLY BURNS THE AMMONIA OFF GOING OUT. THE WIND IS BLOWING
THE RELEASE AWAY FROM THE SITE. THE LICENSEE IS CURRENTLY SHELTERING ITS EMPLOYEES ON SITE.
ALL ECCS AND EDGS ARE OPERABLE AT THIS TIME. THE CONTROL ROOM VENTILATION IS ON RECIRCULATION. |

| THE LICENSEE WAS INFORMED THAT THE LOCAL EMERGENCY MANAGEMENT
AGENCIES PLAN TO SHELTER INDIVIDUALS IN THE IMMEDIATE AREA. TO DO THIS THEY PLAN TO ACTUATE THE EMERGENCY SIRENS IN THE AREA. THE PLANT INTENDS TO REMAIN AT 100% POWER.

ACCORDING TO CONVERSATIONS THAT THE LICENSEE HAS HAD WITH THE
LOCAL EMERGENCY AGENCIES, KOCH INDUSTRIES HAS NO ESTIMATE ON THE
TIME TO REPAIR THE PROBLEM. KOCH INDUSTRIES IS CURRENTLY BURPING
THE AMMONIA TANK FOR 1 MINUTE AT 20 MINUTE INTERVALS AS A SHORT-TERM CORRECTIVE ACTION. THE WINDS ARE STILL BLOWING ANY RELEASE AWAY FROM WATERFORD.
Later TERMINATION of the alert IS BASED ON THE VERIFICATION THAT THE AMMONIA RELEASE AT KOCH INDUSTRIES HAS BEEN STOPPED.
This plant has frequent emergencies from the neighboring chemical plant sited
only a mile away. Simultaneous emergencies could spell total disaster.
