AGREEMENT STATE REPORT - DAMAGED GAUGE
"On 15 Jun 2009 a fixed gauge fell off a digester blow line, about 4 feet onto a grating platform. Licensee staff working in the area noticed the gauge and alerted their supervisor and radiation safety officer. After ensuring the shutter was closed and the source [CS-137; .4092 Ci] was still present, the device (containing its source) was moved to a secure location. Licensee performed wipe surveys to check for leaking / contamination. Meter surveys confirmed the presence of the source, and also the absence of elevated dose rates. There is concern that the welds failed that attached the device to the mounting on the pipe. The manufacturer [Ohmart Vega] has been notified and will assist in arranging return of device (containing its source) and further assessment of cause of failure. The manufacturer uses same model [SR-1A] and serial [#6339] for both source and device."
The Washington State incident number is WA-09-034.
