Title | Truck Shipment External Radiation Levels Exceed Limits |
Event Description | Received Shipment from Pilgrim Station of temporary lead shielding that exceeds 10 CFR 20 requirements for a non-exclusive use limited quantity shipment of 0.5 mR on contact.
Receipt inspection readings of the last container in the shipment measured between 1.3 mR and 1.85 mR (taken via 3 readings, using 3 separate meters and 2 different technicians). Per 10CFR20 subpart 1906 paragraph D, which states: (d) The licensee shall immediately notify the final delivery carrier and the NRC Operations Center (301-816-5100), by telephone, when -- (1) Removable radioactive surface contamination exceeds the limits of section 71.87(i) of this chapter; or (2) External radiation levels exceed the limits of section 71.47 of this chapter. The licensee notified the NRC Resident Inspector.
NRC Notification 44539 was conservatively made due to conservative procedural guidance. 10 CFR 20.1906(d)(2) requires immediate notification of the final delivery carrier and the NRC Operations Center when external radioactive levels exceed the limits of section 71.47 of this chapter. The reporting threshold contained in 10 CFR 71.47 is 200 mR [per hour] at any point on the external surface of the package. Since actual measured levels were between 1.3 mR [per hour] and 1.85 mR [per hour] this event is not reportable. ENS Event Number 44539, made on 10/03/08, is being retracted. The NRC Resident Inspector will be notified by the licensee of this retraction. Notified R1DO (Jackson) & NMSS EO (Regan). |
