Event Notification Report for December 29, 2016

LOSS OF TECHNICAL SUPPPORT CENTER VENTILATION SYSTEM

"Oyster Creek Generating Station has experienced a loss of the TSC [Technical Support Center] ventilation system.

"If an emergency is declared requiring TSC activation during the time TSC ventilation is non-functional, the TSC will be staffed and activated using existing emergency planning procedure unless the TSC becomes uninhabitable due to ambient temperature, radiological, or other conditions. If relocation of the TSC becomes necessary, the Emergency Director will relocate the TSC staff to an alternate location in accordance with applicable site procedures.

"This notification is being made in accordance with 10 CFR 50.72(b)(3)(xiii) due to a potential loss of the TSC. An update will be provided once the TSC ventilation has been restored to normal operation.

"The NRC Resident Inspector has been notified."


* * * UPDATED FROM JOSH MCGUIRE TO DONALD NORWOOD AT 1521 EST ON 12/30/16 * * *

"At 1410 EST on 12/30/16, maintenance is complete and the TSC ventilation system has been restored to normal operation."

The licensee notified the NRC Resident Inspector. Notified R1DO (Lilliendahl).

AGREEMENT STATE REPORT - APPARENT UNCONTAINED RADIATION SOURCE DETECTED

The following information was received via facsimile:

"On December 29, 2016, the Office of Radiological Health (ORH) was notified that radiation had been detected on a local law enforcement officer's personal radiation detector at the intersection of Route 123 and the I-95 southbound exit ramp in Woodbridge, Virginia. The Prince William County HazMat unit responded and identified the source as cesium-137 using a radioisotope identifier. The source was present in the grassy knoll in the median of the interchange. ORH and other agencies, including the Virginia State Police, Virginia Department of Emergency Management and FBI, participated in the initial investigation. The Virginia Department of Transportation, which had representatives at the location, has responsibility for this area and has been requested to arrange for mitigation of the source through the services of a radiation consulting company. Radiation levels were measured at about 10 mR/hr at 1.5 feet above the apparent location of the source and between 30 mR/hr and 50 mR/hr at ground level. Based on the radiation levels and the source location, no radiation exposure occurred to members of the public. The source is apparently below ground and will remain isolated and undisturbed until the Virginia Department of Transportation can arrange for the consultant to remove the item, analyze it, and arrange for its disposal. The consultant is enroute and expected to begin mitigation and disposal efforts late this afternoon. ORH is continuing its investigation and will update this notification when additional information is obtained."

Virginia Event Report ID No.: VA-16-015

* * * UPDATE AT 1451 EST ON 12/30/16 FROM CHARLES COLEMAN TO JEFF HERRERA * * *

The following update was received from the Virginia Radioactive Materials Program via facsimile:

"On December 29, 2016, the Office of Radiological Health (ORR) was notified that radiation had been detected at the intersection of Route 123 and the I-95 southbound exit ramp near Woodbridge, Virginia. The Virginia Department of Transportation (VDOT) took mitigation action. VDOT contacted a radiation safety consulting firm which arrived at the scene that evening. A metallic pellet was found after removal of about one inch of soil. The pellet was confirmed to be a cesium-137 source with an activity of about 8 millicuries and a contact exposure rate of 900 milliRoentgen per hour. It was approximately 7 millimeters in diameter and approximately 15 millimeters long. A field leak test of the source and surveys of the area after removal of the source indicated no contamination. The source was placed in a lead shield inside a DOT 7A Type A steel drum overpack. It was sent to the consulting firm's facility for temporary storage pending disposition. This notification will be updated if additional information becomes available."

Notified the R1DO (Lilliendahl), NMSS (Henderson), ILTAB (Tucker) and NMSS Events (email).

AGREEMENT STATE REPORT - MEDICAL EVENT

The following report was received via fax:

"We [New York State Department of Health] were informed on January 3, 2017 that on December 29, 2016, a 61 year old female patient was to receive SIR spheres Y90 infusion to 2 lesions in her liver at a hospital. The small lesion was to receive 10% and the large lesion was to receive 90% of 24.53 mCi Y90.

"Staff prepared 2 vials according to the Written Directive, and labeled each vial shield. When the first infusion, for the smaller lesion, was called for, a technologist took one vial to the IR room. She believed she had the correct 10% marked vial. She removed the top of the shielded container holding the vial, then she left the IR suite. The patient was injected. When the second infusion, for the large lesion, was called for, the same technologist took the second shielded vial from the hot lab and noticed that it was the one marked with the 10% label. It appears that the vials themselves were not labeled, only the lids of the containers holding the vials were labeled. Once they realized what had happened, they decided to infuse the second larger lesion with what was left over in the first vial as well as what was in the second vial. The licensee has not yet provided the values for the actual administered dose to each lesion. However, it appears clear that the discrepancy in the prescribed activity and administered activity for each lesion meets the reportable medical event criteria.

"[The licensee's] initial report stated there is no harm to the patient. A full report, including the actual activity delivered and a root cause analysis is required/pending."

A Medical Event may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient.
