The following report was received via e-mail:
On May 27, 2016 the Virginia Radioactive Material Program (VRMP) received a reciprocity notification from Heuft USA, Inc., to perform maintenance on a fixed gauge which was not properly functioning. The gauge is a Heuft Model 45US, serial number 1254AR containing 45 mCi of Am-241.
On May 31, 2016 the Heuft service engineer arrived at the Anheuser-Busch facility to investigate the gauge not functioning. The shutter was able to be fully closed but would not fully open. The engineer determined this to be due to a thin piece of material present in the shutter assembly which is not normal, and which interfered with the shutter opening fully. The engineer reported that the root cause of the problem appears that a cylindrical portion of the liner has broken off, perhaps as a result of cyclical thermal stress.
The shutter assembly was replaced and is working properly. There was no public health exposure or environmental release from this event.
