Kentucky Department of Health Radiation Branch (KY
RHB) via email:
KY RHB was notified on 9/6/2019 by a representative from a specifically licensed facility, Big Rivers Electric Corp., that at 1400 EDT on Thursday 09/05/2019, one fixed gauging device (Kay Ray Dual Model 7080, Serial Number 13321G), containing a 100 mCi Cs-137 source (serial No. 12376-V; assay date 6/1/1981) had developed a potential problem. An investigation showed that the shutter remained partially shut when the arm of the on-off shutter mechanism was moved to the fully open position. The gauge is located 25 feet above the floor between fly ash hoppers, and was left on the hopper with the shutter in the closed position. Pending removal of the source no access has been permitted to the two affected hoppers, and all maintenance activities will be delayed until the device has ben removed. No overexposures to the public or to plant workers have been reported. The licensee will be contacting a licensed service provider to remediate this situation.
