UNIT 2 MANUAL REACTOR TRIP DURING STARTUP
"On 12/15/10 at 0148 [CST] Control room personnel initiated a manual reactor trip in order to abort a startup in progress with the Unit 2 Reactor subcritical.
"During the performance of OP-1B, Reactor Startup for Unit 2 both Rod Control System Urgent and Non-Urgent alarms were received. Shortly after receiving the alarms multiple groups of control rods fell into the core as indicated by Individual Rod Position Indicators (IRPl's) and rod bottom lights. Based on these indications a manual reactor trip was initiated. All systems functioned as expected, with all control rods fully inserting. The plant is currently in Mode 3 and operating in accordance with normal plant procedures."
The cause of the control rod alarms is under investigation.
The licensee informed the NRC Resident Inspector.

OFFSITE NOTIFICATION OF AN AMMONIA SPILL INTO THE DELAWARE RIVER
"A notification was made to the New Jersey Department of Environmental Protection of a discharge of approximately 500 gallons of water containing ammonia with a concentration of 1 ppm. The discharge occurred due to the U-1 FHB [Fuel Handling Building] Supply Fan HW coil rupture. The solution was discharged into the storm drain outside of the FHB Annex door. That storm drain leads to a permitted outfall that communicates with the Delaware River. The leak has been isolated and the downstream catch basin plugged. The remaining water in the discharge line upstream of the plugged catch basin will be removed by a contractor.
"There was no out-of service safely related equipment that contributed to this event. No one was injured as a result of this event."
The licensee notified the NRC Resident Inspector.
