POTENTIAL OVEREXPOSURE OF RADIOGRAPHER

The RSO for the licensee called to report a potential overexposure of a radiographer. This event occurred while the radiographer was checking welds at a refinery in Wyoming. While moving the camera to another location, the radiographer's dosimeter alarmed. It is suspected that the camera's source was not fully retracted into the safe position. The source was subsequently retracted back into the fully shielded position.

The RSO calculates an estimated dose to the radiographer of 5 rem. The licensee will send the radiographer's dosimetry for expedited reading as soon as possible.

The licensee will update this report with additional details as they become available.

* * * RETRACTION FROM GAYLE STATON TO HUFFMAN AT 1436 EDT ON 9/04/13 * * *

The RSO has received the radiographer's dosimetry badge readings. The radiographer was still wearing his August dosimetry when the event occurred. His badge readings was 328 mrem for the entire month of August including the exposure from this event.

Since there was no significant exposure from the event, the licensee has retracted this event notification.

The licensee has notified NRC (Thompson) in Region 4. R4DO (Gaddy) notified and a copy of this report was sent to FSME Event Resource.

MAINTENANCE ON TECHNICAL SUPPORT CENTER / OPERATIONS SUPPORT CENTER VENTILATION

"Scheduled maintenance of the Technical Support Center (TSC) / Operations Support Center (OSC) HVAC system for maintenance on the Air Handler (AMA-AH-S1) recirculation fan, outside air duct heater, and thermostat will start at approximately 0400 hours PDT on 09/09/13 and will last approximately 40 hours (estimated time from equipment tag out back to OPERABLE). During this time the TSC and OSC will not be available for use to support emergency response activities. Established compensatory measures direct Emergency Response Organization (ERO) members normally responding to either of these facilities to respond to alternate locations. No other emergency response facilities are impacted by the scheduled TSC / OSC Facilities HVAC maintenance work.

"This event is being reported as a loss of emergency preparedness capabilities in accordance with 10 CFR 50.72(b)(3)(xiii). The resident inspector has been notified. A follow up notification will be made when HVAC maintenance to the TSC / OSC Facilities has been completed and operability of these EP Facilities has been restored."

PLANNED PARTIAL LOSS OF COMMUNICATIONS CAPABILITY IN TECHNICAL SUPPORT CENTER

"This is a non-emergency eight hour notification for a planned loss of communications capability at the DCPP Technical Support Center (TSC). This event is reportable in accordance with 10CFR50.72(b)(3)(xiii) because planned maintenance affects the functionality of some TSC communications systems.

"Planned maintenance activities on the TSC communications systems begins 09/09/13. The work includes removing phones and normal business use computers from service to support a minor remodel which includes the installation of new furniture and painting in the TSC command room. The communications equipment scope of work is confined to the TSC command room only and there is no expected loss of capability in the engineering, administrative or radiological rooms within the TSC. There is no expected loss of plant display systems (SPDS, ERDS, or ERFDS) in the TSC during this planned maintenance. The work is scheduled to complete by 09/26/2013.

"If an emergency is declared requiring TSC activation during this period, the TSC will be staffed and activated using existing emergency planning procedures. A select group of TSC ERO personnel have been pre-designated to respond to their backup TSC location in accordance with applicable site procedures. If a complete relocation of the TSC becomes necessary, the Site Emergency Coordinator will relocate the remaining TSC staff to a backup location in accordance with applicable site procedures. The Emergency Response Organization teams have been notified of the planned maintenance and the possible need to relocate during an emergency.

"The NRC Resident Inspector has been notified. This planned maintenance poses no threat to the public or station employees."

HIGH ENERGY LINE BREAK BARRIER IMPROPERLY OBSTRUCTED

"At 1400 [CDT] on September 9, 2013, plant personnel found HELB barrier HATCH-1/B blocked. The hatch is diamond plate steel located on the turbine floor. Pallets, a fan and a gantry were positioned on top of the hatch possibly preventing pressure relief during a HELB event. This issue is being reported as an unanalyzed condition per 10CFR50.72(b)(3)(ii)(B). All items were removed from the hatch by 1800 on September 9, 2013."
