The following report was received from the state of
Georgia via email:
[On 6/17/2019,] the mill instrumentation group was called to check on a problem with readout from a nuclear gauge indication of high level for the number 26 chip digester. In the course of troubleshooting the problem, the Instrument Mechanic found that the gauge shutter handle would not remain locked in the [full] open position, but would slowly close as the digester operation caused the instrument to vibrate.
The gauge shutter was left in the open position with instructions for operations to notify the Instrument Mechanic if needed. As the shutter for the digester level gauges are open during normal operations, this poses no added safety risk.
Berthold was called and arrangements have been made for them to come on site on 6/27/2019 to either repair or replace the shutter.
The
gauge is a Berthold model LB7442 with a 50 mCi
Co-60 source (serial number 526-03-09).
