Event Notification Report for July 31, 2011

AGREEMENT STATE REPORT - POSSIBLE OVEREXPOSURE TO RADIOGRAPHER

The following report was received from the State of Louisiana via facsimile.

"On Monday, September 12, 2011, LA DEQ [ Louisiana Department of Environmental Quality] received a notification from Integrity [Inspection] Solution that a radiographer's personnel monitoring device received an excessive exposure of 10811mrem for the month of July 2011. The RSO [Radiation Safety Officer] has begun an investigation into the exposure. The individual left the monitor at the office while he was on a week off. The individual was referred to a physician for blood work and will have follow up check ups. Preliminary findings were no unusual activities. Updates will be provided when available."

Event Report ID No: LA-1100XXX

UNPLANNED CONTAMINATION AREA

"On 07/31/11 a water leak was found coming through the C-310 North NaF (Sodium Fluoride) trap room ceiling. The leak was coming from a steam condensate header located over the trap room. The leak had created a puddle, approximately 8' by 6', in the trap room. The area was checked by Health Physics and the spill area in the trap room was upgraded to a Contamination Areas at 1030 [CDT]. The condensate water is not contaminated but is spreading contamination from a contamination area above the ceiling. Decontamination of the trap room has been performed; however, due to a small amount of water that continues to leak into the area the area is being recontaminated. Access to the area has been restricted with the contamination area requirements for more than 24 hours.

"This event is reportable as a 24 hour event in accordance with 10 CFR 76.120(c)(1)(i) 'An unplanned contamination event that: Requires access to the contaminated area, by workers or the public, to be restricted for more than 24 hours by imposing additional radiological controls or by prohibiting entry into the area.'

"The NRC Senior Resident Inspector has been notified of this event.

"PGDP Problem Report No. ATRCÀ11-1944: PGDP Event Report No. PAD-2011-12."

"Once the floor was decontaminated and down posted, which was within the 24-hour limit, a Nuclear Criticality Safety (NCS) approved 5.5 gallon container was placed on the floor to contain the continuing leak. Due to the fact that the water dripping into the container was contaminated, the container was posted as a contamination area. The above statement that the area was being recontaminated by a small amount of water that continued to leak is referring to the water dripping into the bucket. A review of the sequence of actions to contain the water leak and decontaminate the area resulted in the conclusion that the contaminated area was down posted within the 24-hour limit. The fact that the NCS approved 5.5 gallon container placed on the floor to contain the leak was posted as a contamination area is not considered a continuation of the spread of contamination event. The spread of contamination onto the floor had been stopped and the floor decontaminated. With the leak contained, the floor decontaminated, and returned to the radiological control level that existed prior to the leak within the 24-hour limit, the event notification was not required. Thus, the notification is being retracted."

The licensee has notified the NRC Resident Inspector.
