REMOVABLE SURFACE CONTAMINATION GREATER THAN THE LIMITS Nuclear Fuel Services (NFS) received a shipment of natural uranium [DELETED] from CAMECO [DELETED]. When the receipt survey was begun, one of the 55-gallon drums was found to be contaminated on the bottom. The survey result was 455 disintegrations per minute (DPM)/100 square centimeters. [The limit is 220 DPM/100 sq cm.] Access to the drum was restricted by placing it into a roped off area. The remaining drums are being surveyed. [DELETED] drums were received and four have been surveyed. Access to all of the drums has been restricted until they are surveyed. Since the contamination was found after the delivery truck had been released, the consignor has been notified of the event and has been requested to check the truck for contamination. The licensee notified the NRC Resident Inspector and the State of Tennessee.
Nuclear Fuel Services, Inc. (NFS) wishes to withdraw the Notification of an Event which was made on June 24, 2004 at 1852 hours0.0214 days <br />0.514 hours <br />0.00306 weeks <br />7.04686e-4 months <br />. The event number was #40840. The immediate event notification was made because NFS' procedure required an immediate notification in the event a package was received and was found to be contaminated in excess of 220 DPM/100 square centimeters of alpha activity. This procedure was intended to implement the requirements of 10 CFR 20.1906(d)(1). The material involved in this event was natural uranium, which is a low toxicity alpha emitter as defined by 49 CFR 173.403. 49 CFR 173.443, which is referenced by 10 CFR 71.87(i) which in turn is referenced by 10 CFR 20.1906(d)(1), gives the non-fixed radioactive wipe limit for this material as 22 DPM/square centimeter. This limit converts to 2,200 DPM/100 square centimeters of alpha activity, which is considerably more than the 455 DPM/100 square centimeters of alpha activity which precipitated this incident. A repeat survey confirmed this contamination level and found no other elevated shipping packages. To prevent a recurrence of this notification, NFS is revising procedure NFS-HS-A-50, rev. 12 to provide a differentiation between alpha emitters and low-toxicity alpha emitters. The licensee has notified the NRC Resident Inspector (via email and voice mail) and the State of Tennessee. Notified R2DO (Carolyn Evans) and NMSS EO (Scott Moore).
