AGREEMENT STATE REPORT - RADIOGRAPHY SOURCE DISCONNECT AND RECOVERY

The following information was received by e-mail:

"On December 22, 2011, at 2102 hours, the Agency was notified by Harris County Hazmat that a radiography truck had been involved in an accident. The truck was carrying a Spec 150 camera serial # 153 containing a 32 curie Iridium 192 source. The radiographer informed the Hazmat officer that the source in the camera was not in the locked position. The radiographer stated that the source had separated from the drive cable and he had used a pair of pliers to insert the source into the camera backwards to shield it. The camera opening for the guide tube connection was covered with duct tape to prevent the source from coming out of the camera. The radiographer could not get the crank out device to separate from the camera so the camera and the crank out devices were placed between the transport container and the darkroom wall to transport them back to the storage location. The accident caused the source to move further to the back of the 'S' tube in the camera and the dose rates from the camera increased slightly. The crank out device was used to push the source back to the shielded position. Lead sheets were placed above the camera to help decrease the dose rates from the camera. The dose rates at this point were between two and four millirem at one meter. The radiographer took the camera and source to the licensee's storage location. The source was removed from the radiography camera and placed in a source changer shield. The radiographer stated that he had received 180 millirem for the event. No member of the general public received exposure due to this event. The licensee will return the source and camera to the manufacturer for inspection. Additional information will be provided as it is received in accordance with SA-300."

OFFSITE NOTIFICATION TO STATE OF NEW JERSEY DUE TO A DISCHARGE INTO THE DELAWARE RIVER

"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.

"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."
