AGREEMENT STATE REPORT - STOLEN TROXLER GAUGE
The following information was received via fax:
"This First Notice constitutes EARLY notice of events of POSSIBLE safety or public interest significance. The information is as initially received WITHOUT verification or evaluation, and is basically all that is known by the Agency [Arizona Radiation Regulatory Agency] Staff at this time.
"At approximately 1000 MDT, March 28, 2011, the Agency was informed that the Licensee had a Troxler Model 3241-C, SN 1884, asphalt content gauge stolen from the F & F construction trailer at the Casa Grande job site. The theft occurred over the weekend. The gauge was locked with a chain in the construction trailer which was parked in a locked, fenced construction job site. The gauge contains 100 mCi Am-241:Be.
"Casa Grande PD is investigating. The Agency continues to look for the source. The states of CA, NV, CO, UT, and NM and Mexico and U.S. NRC and FBI are being notified of this event."
THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL
Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks. For additional information go to http://www-pub.iaea.org/MTCD/publications/PDF/Pub1227_web.pdf
This source is not amongst those sources or devices identified by the IAEA Code of Conduct for the Safety & Security of Radioactive Sources to be of concern from a radiological standpoint. Therefore is it being categorized as a less than Category 3 source

UNUSUAL EVENT DECLARED DUE TO SMOKE COMING FROM AN ELEVATOR CONTROL CABINET
At 1129 EDT on 03/28/11, smoke was detected coming from an elevator power supply transformer in the "B" Residual Heat Removal (RHR) vault. The licensee declared a Unusual Event at 1143 EDT. At 1146 EDT the fire brigade responded and found smoke only and no flame. The smoke stopped when the cabinet was de-energized. At 1158 EDT, the fire was proven to be out when the cabinet was opened. No fire fighting extinguishing agents were used. There was no damage to other plant equipment and no personnel injuries. At 1151 EDT, the licensee notified the States of New Hampshire and Massachusetts and at 1209 EDT, activated their Technical Support Center (TSC). The plant was operating at 100% power and remained stable during and after the event.
The licensee notified the NRC Resident Inspector.

"At 1243 EDT on 03/28/11, the Unusual Event was terminated. Subsequent investigation has revealed that no plant equipment damage beyond a power transformer that supplies an equipment elevator occurred. There was no indication of [visible] flame (smoke only) and no personnel injuries as a result of the event."
The licensee notified the NRC Resident Inspector.
