At 2209 EST on 12/28/11 following a planne … At 2209 EST on 12/28/11 following a planned station service water (SSW) pump swap, a motor operated valve (MOV) failed to close in a water treatment system for the SSW pump that was secured. This was discovered shortly after the pump was removed from service by the field operators. The control room was notified at 2230 EST of the issue and ongoing efforts to troubleshoot and correct the malfunction. The release was terminated by closing a manual isolation valve at 2240 EST. This malfunction resulted in the discharge of approximately 17 gallons of 15% sodium hypochlorite (product) to the idle SSW pump intake which communicates with the Delaware river, The idle SSW pump was restarted at 2240 EST thus withdrawing all residual product from the intake and directing it to plant treatment systems (dechlorination on the cooling tower outfall). 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 is reportable to the state of NJDEP (New Jersey Department of Environmental Protection) within 2 hours. The report to the state was initiated at 0017 EST on 12/29/11.</br>The HC Senior NRC Resident has been informed. Affected systems are limited to the Station Service Water (SSW) system and the Sodium Hypochlorite water treatment system. There were no actuations or initiating signals. There was no impact on plant operations and these systems remain fully operable. The failure was limited to the MOV which has been isolated via a manual valve. There was nothing unusual or not understood. All safety related equipment continues to function as required. There were no injuries or reported wildlife impact.e no injuries or reported wildlife impact. +
