SOURCE DISCONNECT FROM RADIOGRAPHY CAMERA DRIVE CABLE

The Agency (State) was notified (at 1645 CDT) by the licensees RSO that they had a source disconnect and that the source was later retracted. The event involved an INC IR-100 camera containing a 94 curie Ir-192 source. The source was in use for about one week, about 6 jobs. A local Texas inspector went to the site to investigate the event.

The licensee later notified the Agency (State) that in this case, the connector crimped fitted on the source pig tail had separated from the source drive cable. The two individuals who returned the source to the camera housing received 425 millirem by self reading dosimeter for one worker, and between 750 and 800 millirem calculated for the other worker. The RSO stated that neither worker exceeded the annual DDE limit. TLD's for the workers involved have been sent to their processor and the results should be back on 3/9/09. The State of California has been informed of the event.

On March 13, 2009, the RSO notified the Agency (State) that the radiography camera had been packaged and will be returned to the manufacturer today.

Texas Incident # I-8614

UPDATE FROM ART TUCKER VIA EMAIL TO JOHN KNOKE AT 1237 0N 04/14/09

"[The State] received exposure reports for two workers involved in the source retrieval. The support individual received 299 millirem DDE, and the individual who actually retrieved the source received 502 millirem DDE, and 425 millirem calculated to the hand."

Notified FSME (Angela McIntosh) and R4DO (Jack Whitten)

* * * UPDATE ON 06/05/2009 AT 1015 FROM ART TUCKER TO VINCE KLCO * * *

Report received via e-mail:

"The [State of Texas] received the following information from the manufacturer of the source device:

"[The] license, Industrial Nuclear Company [INC], was notified by Desert Industrial X-ray that there had been a source disconnect of 97 curies, source S/N-N597 on March 5, 2009. Source and connector was received at Industrial Nuclear Co, Inc on March 13, 2009.

"Upon inspection of source connector [on] S/N- N597 that was received from Desert Industrial X-ray, INC found no evidence [of] physical damage. The cable appeared to have some stretching but not any more than would be expected after the pull test.

"Dimensions were performed on all previous inspected source assembly components and found to be within design limits.

"All INC source connector assemblies in inventory (from the same manufacturing date) were re-load tested and all passed. INC has to date never had a Source Connector come off in pre-inspection or after it was put in use. INC has not been able to discover just how this might have happened. In the report the licensee stated the connector crimp failed. INC has tried to recreate this event but [has] had no success in doing so. The licensee said the source had been in use for one week [and] if the source connector crimp was bad it should had failed on the first day.

"The licensee has not reported any additional problems associated with their exposure devices."

Notified R4DO (Lantz) and FSME EO (McIntosh)

AGREEMENT STATE REPORT - UNABLE TO RETRACT RADIOGRAPHY SOURCE

The following information was obtained from the State of Arkansas via email:

"On June 1, 2009 at 1600, the licensee notified the Department [Arkansas Department of Health] that while retracting the source after a shot, the source stopped and could not be retracted into the camera and could not be moved into the collimator. This occurred at 1545. The radiography is conducted inside an open top and open ended cell at the facility. The radiography crew evacuated the cell area, adjacent work areas and established a 2 mR/hr boundary around the cell. Observing from the far end of the cell, the radiography crew established that the piece of pipe being radiographed fell from the work table onto the guide tube. The radiography crew notified the State of Arkansas and also QSA Global in Baton Rouge, LA.

"The State of Arkansas sent two Health Physicists to the facility. [They arrived] at 2320 and remained on site throughout the source retrieval.

"QSA Global responded to the site at 0030 on the morning of June 2, 2009. Using portable shielding and standard radiation safety practices, QSA Global personnel were able to move the source into the collimator, cut out the crimped guide tube, and return the source to the camera at 0230 on the morning of June 2.

"The Camera involved: Industrial Nuclear Company, Inc., Model IR-100, Serial Number 4150.

"The Source involved: QSA Global, Model 87703, Serial 49390B, manufactured on April 8, 2009 and contained 64 Curies at the time of the incident.

"The Camera has been taken out of service for repair and inspection.

"The State of Arkansas is awaiting a report from QSA Global and the licensee."

TECHNCIAL SUPPORT CENTER VENTILATION SYSTEM OUT OF SERVICE

"Planned maintenance activities are being performed today (June 5, 2009) on the Hatch Nuclear Plant's Technical Support Center (TSC). This work activity is planned to be performed and completed expeditiously within one work shift (less than 12 hours). This maintenance activity is to repair or replace solenoid for valve 1X75F003 on the TSC HVAC System which is not always reliably opening. During this work the TSC HVAC will be rendered non-functional during the performance of the work activity.

"If an emergency condition occurs that requires activation of the Technical Support Center during this work activity, it will take no more than two hours to return the equipment back to functional status, dependent on the stage of the work activity at the time the emergency occurs. Plans are to utilize the TSC for any declared emergency during the time the work activity is being performed, as long as radiological conditions allow. Procedure 73EP-EIP-063-0, Technical Support Center Activation, provides instructions to direct TSC management to the Control Room and TSC support personnel to the Simulator Building to continue TSC activities if it is necessary to relocate from the primary TSC.

"This event is reportable per 10CFR50.72 (b)(3)(xiii) as described in NUREG-1022, Rev. 2 since this work activity affects an emergency response facility for the duration of the evolution."

The licensee has notified the NRC Resident Inspector.

* * * UPDATE FROM B. COLEMAN TO J. KOZAL AT 1406 EDT ON 6/5/09 * * *

The planned maintenance activities are complete and the TSC ventilation system has been returned to service. The licensee has notified the NRC Resident Inspector. Notified R2DO (Lesser).

VOLUNTARY NOTIFICATION - MOVING IRRADIATED STEAM DRYER IN A SHIELDED CONTAINER

The NRC Operations Center was pre-notified of the following activity:

"The following was determined to be an Event of Potential Public Interest (EPPI) and required reporting to the Pennsylvania Emergency Management Agency (PEMA).

"On Saturday, 06/06/09 and Sunday, 06/07/09, Susquehanna will be moving an irradiated steam dryer from the reactor building to an onsite storage area. The dryer will be in a shielded container to minimize personnel dose during the move. In addition, access to the owner controlled areas near the site will be restricted. The presence of these controls may result in public inquiries about this planned activity.

"If onsite emergency response is required during the move, offsite agencies that support Susquehanna will not be impacted. Susquehanna will maintain the ability of Fire and Emergency Medical personnel to access the site."

The licensee will notify the NRC Resident Inspector.

OFFSITE NOTIFICATION MADE DUE TO ELEVATED LEVELS OF TRITIUM

"This notification is being made pursuant to 10 CFR 50.72(b)(2)(xi) due to the fact that Exelon Nuclear has informed the Illinois Emergency Management Agency and Illinois Environmental Protection Agency of recent groundwater monitoring results at Dresden Station. This notification was made at 15:22 hours CDT on June 6, 2009.

"As part of the Station's continuing environmental monitoring and sampling program, sample results from some of the monitoring wells have indicated elevated levels of tritium requiring notification of the State of Illinois. Based on sampling data obtained to date, the tritium in the groundwater is confined to Exelon property and poses no threat to public health or safety.

"The IEPA/ IEMA regulation requires notification when a release to soil, groundwater, or surface water goes off-site at greater than 200 pCi/L or remains on-site greater than 0.002 Curies. Based upon the monitoring well results and the volume and concentration of groundwater infiltration into the nearby storm sewer, it is likely that the 0.002 Curie on-site threshold has been exceeded.

"The Station continues to track this issue by monitoring the existing wells and initiation of mitigative actions to contain any release and ensure it remains on-site. At this time, the source of the tritium has not been identified.

"The licensee has notified the NRC Resident Inspector."
