| ENS 54462 | 3 January 2020 13:15:00 | On 1/2/2020, it was discovered that the shutter on a centrifuge process level gauge was stuck in the open position. The gauge is a Berthold model LB7442F, serial number 6005 containing a 3000 mCi Cs-137 source. The source serial number is 5559GN. The shutter is normally open during process operation and closed during maintenance. Red tape and plywood have been erected in order to prevent inadvertent personnel entry into the area. No over-exposures have occurred. A Berthold representative should be on-site next week to repair the shutter. |
| ENS 52296 | 14 October 2016 14:17:00 | The licensee Radiation Safety Officer (RSO) determined that the shutter to a Berthold Model LB7442 gauge with a 1 Ci Cs-137 source (serial number: 012\06) did not shut during biannual maintenance checks. Personnel is informed about the gauge with proper signage, and the RSO does not believe any exposure to personnel occurred, because the shutter is normally in the open position. A licensed Berthold technician has been contacted and will come to the site to repair the gauge. The licensee notified NRC Region 3 (Nieves). |
