AGREEMENT STATE REPORT - FIXED DENSITY GAUGE STUCK SHUTTER

The following information was received from the State of Nebraska via facsimile:

"The licensee uses fixed industrial gauges for measuring densities in fly ash hoppers at the stations precipitator building. The industrial gauges contain a Cesium-137 sealed source. The Cesium-137 sources were originally installed in 1975 and at the time contained 50 millicuries per source. The sources were manufactured and installed by Kay Ray, Inc. The gauges are Model No. 7700-50.

"The licensee was attempting to close the shutter on the fixed gauge prior to performing maintenance. One of the external closure cables was found to be slightly bound up and only partially closed the 'internal' source shutter. The cable closure was reopened, which reopened the source shutter up at the sealed source. Closure was tried again. This time the cable, which connects the handle at the floor to the sealed source shutter mechanism 20 feet above, bent instead of sliding the cable to the closed position. The 'event' happened at 9:50 am and was reported to the station's Shift Supervisor who in turn contacted the plant electricians to make repairs so the precipitator 'tag-out' could continue. By 11:00 am the [shutter] had been closed and the lab contacted to perform a survey to verify the source shutter was now in the closed position. No personnel were exposed to radiation during this event."

AGREEMENT STATE REPORT - FOUND PORTABLE DENSITY GAUGE

The following information was received from the State of Colorado via facsimile:

"On 3/29/10 this department was notified of a portable density gauge that had been left at a property that had been foreclosed on. We responded to the property and found a CPN MC-3 density gauge. The s/n M390304939. We have taken possession of the gauge and it is now being stored in a secure area. We have contacted the manufacturer who is attempting to track the serial number."

According to the NMED database, this gauge was reported stolen in 1999. The gauge contained 50 mCi of Am-241/Be and 10 mCi of Cs-137.

NMED Report #990562.
