AGREEMENT STATE REPORT - MOISTURE DENSITY GAUGE DAMAGED AT JOBSITE
The State of Texas supplied the following information via email:
"The RSO for Rone Engineering contacted the Texas Radiation Program by phone on 4 May 2012 at approximately 10:15 AM CDT. The RSO reported a gauge had been damaged when run over by a water truck on a highway construction site in San Antonio. The RSO requested a radiation program inspector to conduct a radiation survey of the device because there was no radiation detection equipment immediately available.
"An inspector was dispatched to the site and reported that the device was severely damaged, but the radioactive sources were still shielded. However, the source rod was broken and radiation levels at the point where it broke were measured to be 86 millirem per hour. The licensee contacted a company licensed to recover and ship radioactive sources. The recovery company packaged the gauge and will return it to the manufacturer.
"The gauge was a Troxler 3430 plus, Serial number 60001. The gauge contained two sources; one 0.696 GBq Cs-137 and one 1.48 GBq Am-241 The Cs-137 source serial number was 77-7272 and the Am-241 source serial number was 78-4445."

CONTAINMENT EQUIPMENT NOT ANALYZED FOR ENVIRONMENTAL CONDITIONS OF RECORD
"While evaluating the station environmental equipment qualification for equipment inside the containment it was determined that a number of different pieces of equipment were not analyzed for the environmental conditions associated with the current analysis of record. The equipment is subject to adverse conditions for a time frame longer than currently accounted for (220 verses 60 seconds). In addition, the equipment is subject to potentially different temperature effect than that to which it is currently analyzed. This affects a variety of equipment in containment."
The licensee notified the NRC Resident Inspector.
