Indiana Harbor's [Radiation Safety Officer] RSO was notified of a problem with a gauge at the IH7 Blast Furnace operations at 1101 CDT on April 9, 2019. This issue has the potential to be a shutter failure. [Source details] Kay Ray model 7064P, serial number 8318, Cs-137, originally 5000 mCi (1978) estimated 2000 mCi remaining. There is no exposure potential. It is installed on the North Lockhopper at the # 7 blast furnace on elevation 13. Upon attempting to unlock the 'North Lockhopper empty' gauge, the shutter arm was moving freely. The position of the shutter is not know, however, the source beam is directed into the hopper if the shutter is open and there are no personnel that can access the beam while the furnace is in operation. The next opportunity to access the gauge will be during the next scheduled outage on June 4 or 5, 2019." | Indiana Harbor's [Radiation Safety Officer] RSO was notified of a problem with a gauge at the IH7 Blast Furnace operations at 1101 CDT on April 9, 2019.
