On May 11, 2009, at approximately 1130 CST … On May 11, 2009, at approximately 1130 CST, licensee initial evaluation concluded that events meeting the 24 hour reporting criteria of 10CFR40.60 (b)(1) had not been reported during the period 10/17/08 through 03/29/09 (37 events total). Each event involved leakage from processing equipment located in the Feeds Material Building, (FMB). The material involved in each case was either natural uranium, or UF4 (green salt), in the form of a dry powder or dust. It is believed in each case the quantity of material exceeded 5 times the lowest ALI as specified in 10CFR40.60(b)(1)(ii), which for this material is less than 3 grams. </br>In each case appropriate protective measures were applied when contamination was discovered. Protective measures included turning on precautionary lights, and requiring the wearing of respirators for personnel entering affected areas. Cleanup of affected areas was also conducted.</br>A more conservative interpretation of which events are considered unplanned versus planned has been incorporated. The previous interpretation historically applied, considered the event planned, if at the first indication of leakage, mitigating actions were initiated. The more conservative interpretation will incorporate considering the event unplanned, if mitigating measures were not already in place for a planned activity at the time of discovery. This more conservative interpretation has been discussed with NRC Region II, has been adopted as the facility's practice, and communicated to licensee management.</br>Review of personnel bioassay data indicates no resulting increase in personnel dose measurements. Review of liquid and gaseous effluent data, and sampling data from the restricted area boundary all indicate no significant increases in effluent measurements, and all analytical results are well within regulatory limits. There is no impact to plant workers or members of the public as a result of this event. Routine contamination surveys are being conducted in accordance with Health Physics program procedures, and results are reviewed with the plant ALARA committee. </br>This event will be addressed by corrective actions in accordance with the plant Corrective Action Program. with the plant Corrective Action Program.
