| Title | Unplanned Contamination Event |
| Event Description | An unplanned contamination event occurred on 8 September 2005. This is a reportable event in accordance with 10CFR40.60 sub paragraph(1) based on an unplanned event that resulted in additional radiological controls being required for more than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. The 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> period ended at 1000 on 9 September 2005 [the reported event date]. The additional control imposed was the wearing of air purifying respirators on the second floor of the Feed Materials Building. The location of the events was the Feed Materials Building second floor. The Feed Materials Building converts milled uranium oxide material to uranium hexafluoride by using a dry process. Air samples from the second floor were analyzed and the airborne radioactivity averaged approximately 6.5E-11 microCuries/ml. The airborne contaminant was natural uranium ore concentrate and the physical form is a light microscopic dust. The processes in the area of the elevated levels of airborne radioactivity have been secured and potential leakage paths are being investigated.
The licensee stated that bioassay sampling of exposed individuals will be performed within the routine sampling frequency, but prior to 09/30/05. The licensee notified NRC Region 2 (D. Collins). |
