RADIOGRAPHY CAMERA SOURCE LOCK MALFUNCTION
A radiography crew working the Kuparuk Oil Field on the North Slope of Alaska experienced a malfunction of the locking system on an INC IR-100 exposure device.
After completing radiography activities, the source was cranked in however, the source was still 1/4 to 1/2 inch from the fully retracted position. There were no abnormal readings observed and the key was turned to the locked position. The crew has been trained for this type of situation. They dismantled the lock, cleaned it, rebuilt it, and retracted the source to its fully retracted position.
Exposure Device: Industrial Nuclear IR-100
Device S/N: 6774
Source S/N: 70129B
Source Activity: 80 curies
Source Type: Ir192
There was no exposure from this event.

The following report was received via fax:
"On November 5th, the radiography crew working the Kuparuk Oil Field on the North Slope of Alaska experienced a malfunctioning locking system on an INC IR-100 exposure device (serial number 6774).
"During the shift, the source was cranked in and the camera was surveyed per the proper procedure. There were no abnormal readings observed during the survey and the key was turned to the lock position. When the crank assembly was removed it was noted that the pigtail was not fully seated.
"The 2 mR/hr boundary was reconfirmed and the Foreman and Supervisor were notified. The camera was surveyed and noted as being safe to transport. The camera was tagged out and placed in the Permanent Storage facility. A trained radiographer removed and cleaned the locking system. The locking system was successfully reinstalled. The camera has been returned to service.
"Exposure Device: Industrial Nuclear IR-100
Device S/N: 6774
Source S/N: 70129B
Source Activity: 63.4 curies
Source Type: Ir-192
Source Model # QSA 87703"
There was no exposure to the crew or the general public during this incident.

TECHNICAL SUPPORT CENTER VENTILATION MAINTENANCE
"Maintenance activities are being performed on the Hatch Nuclear Plant's Technical Support Center (TSC) Emergency Ventilation System starting on November 5, 2011 at 0900. These maintenance activities include the replacing the TSC HVAC cooling coils, condensing unit and controls. The maintenance activity will be worked 24 hours per day until completion. The scheduled completion date is November 10, 2011.
"During the time these activities are being performed, the TSC air handling unit, TSC condensing unit, TSC filter train and the fan unit for the TSC filter train will not be available for operation. As such, the TSC HVAC will be rendered non-functional during the performance of this work activity. If an emergency is declared requiring activation of the TSC during the time these work activities are being performed, then the contingency plans call for utilization of the TSC during the time of these work activities, as long as environmental and radiological habitability 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 so that TSC functions can be continued.
"This event is reportable per 10CFR50.72 (b)(3)(xiii) as described in NUREG-1022, Rev.1 since this work activity affects an emergency response facility for the duration of the evolution."
The licensee notified the NRC Resident Inspector.
* * * UPDATE FROM CHUCK VONIER TO HOWIE CROUCH AT 1655 EDT ON 11/10/11 * * *
The TSC was returned to service at 1621 EDT.
The licensee has notified the NRC Resident Inspector. Notified R2DO (Hopper).

MAJOR LOSS OF EMERGENCY PREPAREDNESS CAPABILITY DUE TO NETWORK ISOLATION DEVICE FAILURE
"At 12:30 PDT on 11-5-2011, a network isolation device failed, resulting in interruption of the feed of plant data to emergency response facilities as well as loss of Emergency Response Data System (ERDS) transmission capabilities. At approximately 05:00 PST on 11-6-11, actions were initiated to reboot the system and capability was restored at 06:30 PST on 11-6-11. On 11-15-11, the time of the original device failure was identified and it was determined the total outage time was approximately 19 hours (including accounting for the change from daylight to standard time). It was further concluded this represents a major loss of emergency preparedness capability. Emergency assessment equipment in the control room was available throughout the event."
