Event Notification Report for December 07, 2012

PLANNED EMERGENCY OFFSITE FACILITY/TECHNICAL SUPPORT CENTER VENTILATION MAINTENANCE

"This is a non-emergency eight hour notification for a loss of Emergency Assessment Capability.

"On December 7, 2012, the EOF/TSC air handler chiller unit was removed from service to perform planned maintenance. This maintenance activity will not affect the air filtration portion of the system and these facilities remain available for use during an emergency. This maintenance activity will be performed in a manner to minimize the time that the air handler chiller is out of service. This maintenance activity impacts the ability to maintain ambient air temperature in the facilities. The estimated duration of this activity is planned to be 12 hours.

"If an emergency condition occurs that requires activation of the emergency response facilities, the EOF and TSC will be utilized. The Emergency Response Organization team members have the ability to relocate to alternate locations in accordance with emergency implementing procedures based on conditions. Alternate emergency response facilities will remain available in the event that relocation is necessary. This report is being made in accordance with 10 CFR 50.72(b)(3)(xiii), which is any event that results in a major loss of emergency assessment capability, offsite response capability, or offsite communications capability. An update message will be provided when the emergency response facilities are restored."

The licensee has notified the NRC Resident Inspector, State and local authorities.

THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL

Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.

AGREEMENT STATE REPORT - CONTAMINATION EVENT

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

"On 12/10/12 at 4:30 pm EST, [the] RSO [at] Energy Solutions-Bear Creek called [the State of Tennessee] to report that last Friday, 12/7/12, a drum of DU shavings had been placed in Area 9 of the old ATG building and covered w/mineral oil. When [workers] came to work on 12/10/12, they noticed that the poly drum was completely gone, the shavings were on the floor, oil was on the floor and some of the shavings looked like ash. The poly drum had burned up and the drum/shavings and oil/ash/shavings were now on the concrete floor. There was no stack release. The stack samples were pulled and indicated less than MDA: < E-14 for U-238 and <E-15 for U- 235. Workers were not allowed to enter the area/bldg. A Hi-Volume sample was pulled with no detectable findings. Smear samples were taken with a maximum reading of 11,000 dpm. The pre-filter will be removed and counted. [Workers] are in the process of checking the temperature from a distance using a remote thermometer in order to determine if they can transfer the shavings from the floor into another oil filled container. There was no release into any drains, there was no release into the air, and there were no personnel involved/no personnel contamination. A written report is being prepared and will be sent to the Division [Tennessee Division of Radiological Health]."

Tennessee Report No.: TN-12-305


* * * UPDATE FROM LAURA TURNER TO DONALD NORWOOD AT 1153 EDT ON 5/7/2013 * * *

The following report was received via e-mail:

This is a request for event notification (EN #48577) to be retracted.

"The State of Tennessee Division of Radiological Health (DRH) investigation has determined, based on the information Energy Solutions (ES) supplied and the amount of DU [Depleted Uranium] lost, incident TN-12-305 did not meet the reporting requirements for the greater than five times ALI criteria. Therefore, Event Notification Report #48577 is being retracted.

"It was concluded that 126 grams of DU, or less than 37 MBq (1 mCi) of activity, is unaccounted for as a result of the oxidation incident. Energy Solutions stated that the work area sample results were 0.46 uBq/ml (1.25E-11 uCi/ml) alpha and 1.85 uBq/ml (5E-11 uCi/ml) beta with field instrument checks. Results were also less than MDA alpha and 0.2 (5.46E-12) beta with laboratory equipment checks (gamma spec). Correspondingly, the field check revealed 1.79 DAC based on 0.26 uBq/ml (7E-12 uCi/ml) DAC for Pu-239. Energy Solutions concluded that an inappropriate storage vessel was used. Corrective actions included operator training, procedural revisions, and external review by proper ES personnel."
