v t e ENS Event
19:53 Oct 5, 2011
Title	Offsite Notification Due to Potential Chemical Spill in the Delaware River
Event Description	At 0930 on 10/5/11, a fuse failure in a 1E to non - 1E interface failed causing a false run signal to the water treatment system for a standby station service water pump. The water treatment system responded by opening the injection valve for the out of service pump. With the associated pump out of service, the sodium hypochlorite can communicate with the Delaware river. This was discovered at 1553 and immediately terminated. This resulted in the discharge of approximately 195 gallons of 15% sodium hypochlorite to SSW intake which communicates with the Delaware river. The associated service water pump was started thus withdrawing residual product from the intake. A portion of the discharged sodium hypochlorite may have entered the Delaware river. A sample was obtained from the Delaware river just outside the intake structure and there was no detectable chlorine in the sample and there were no abnormal conditions noted on the river. Based on Environmental Licensing review, this was reportable to the state of NJ within 15 minutes. The report to the state was initiated at 1608 on 10/5/11. Subsequent calls were made to the Hope Creek Senior NRC Resident, the National Response Center and the US Coast Guard. Affected systems are limited to the Station Service Water (SSW) system and the sodium hypochlorite water treatment system. There was no impact on plant operations and these systems remain fully operable. Evaluation is underway to fully understand the impacts of the fuse failure to prevent reoccurrence. There was nothing unusual or not understood. All safety related equipment continues to function as required. There were no injuries or reported wildlife impact.
