OFFSITE NOTIFICATION REGARDING THE DISCOVERY OF AN OLD SPENT BLASTING CAP IN THE YARD OUTSIDE THE PROTECTED AREA
The following text is a portion of a facsimile received from the licensee:
"Offsite agency assistance [was] requested to assess a spent blasting cap found outside the Protected Area in the yard. A City of Rock Hill explosives expert was requested by security to assess/take possession of the spent blasting cap."
"The explosives expert determined that the blasting cap was spent[. The explosives expert also] determined its age as 10-20 years at least and [that it] was leftover from the construction of the site. The officer took possession of the spent blasting cap and removed it from the site at 1507 EDT."
The licensee notified the NRC resident inspector and City of Rock Hill Police Department in South Carolina. The licensee also plans to notify the States of North Carolina and South Carolina as well as York, Gaston, and Mecklenburg Counties.

DISCOVERY OF CONTAMINATION/TRITIUM LEAKAGE ON AN M-1 TANK MUZZLE REFERENCE SENSOR AT THE US ARMY ABERDEEN TEST SITE TANK RANGE
While preparing a tank for shipment, the licensee discovered that an M-1 Tank Muzzle Reference Sensor (MRS) containing 10 curies of tritium was leaking and discharged to the atmosphere. The exact time that the leak occurred is not currently known. Apparently, 200 rounds were fired from this tank, and then the MRS was checked prior to shipment of the tank to Michigan. Three swipe counts were performed, and the contamination levels ranged between 150,000 and 170,000 dpm/100 cm².
The licensee stated that there were no personnel contaminations as a result of this event. A swipe count was performed on the hands of the individual who installed the MRS, and it was negative. Urinalysis is also being performed as a precautionary measure, and the results are pending. Apparently, no other personnel came into contact with the leaking MRS.
The leaking MRS was removed, double bagged, and placed in storage. The licensee plans to dispose of it as radioactive waste.
There was minimal contamination on the tank gun tube, and it was cleaned to acceptable levels (below limits). The licensee plans to ship the tank without the MRS.
(Call the NRC operations officer for a contact telephone number for the licensee's Radiation Safety Officer.)
