| Title | Fixed Gauge Shutter Failure |
| Event Description | On 9/8/2011, during site cleanup activities, workers at the Greenfields coal processing facility near Pageton, WV unexpectedly discovered two generally licensed, fixed-type gauges in a remote, back lot area of the plant property. One of the gauges had a stuck open shutter. The gauges are currently clamped to pipes, roped off in an area restricted from personnel access, at about a 300 foot distance from personnel. No threat to health and safety exists at this time.
The gauges are designed to be affixed to piping for industrial process control, but were found among various discarded metal parts. An inspector from the West Virginia Radiological Health Program took survey measurements and verified there was no spread of contamination. Dose rates outside of the gauge casing are about 0.4 mRem/hr. Dose rates inside of the pipes are about 40 mRem/hr, which indicates that the shutters are likely open. Facility personnel will take photos of the gauges and send to NRC Region I. Additionally, they intend to place the gauges with the piping in a locked gang box that will be chained and locked to a fixed metal structure. The facility owner, Deep Green, is taking steps to have the material removed from the site. Gauge information: [2] Berthold Technologies gauges, Model No. LB 7440 D; 30 mCi, Cs-137 source (Sep. 21, 2001); Source serial # HE681 manufactured by AEA Technologies, model CDC.p4; SSD Safety Evaluation No. TN-1031-D-101-B. |
