STUCK RADIOGRAPHY CAMERA SOURCE
The following information was received via E-mail:
"At approximately 0018 YDT on 5/5/2019, a Kakivik radiographic crew working in Alpine, Alaska on drill site CD-4, could not retract a source under normal conditions. Once this was identified the crew initiated emergency procedures by establishing 2mR boundaries and making notifications per O&E procedures. The crew was using a QSA Global 880D device with a model A424-9, 44.6, Ci Ir-192 source along with a 10HVL collimator. The crew had made 15 exposures. The last exposure is when the Radiographer noticed a sudden stop from the drive cable during his retraction and that is what initiated the emergency procedures. At approximately 0308 YDT the source was locked and secured in the 880D device. It was determined that the guide tube was draped low in a 'W' shape at the guide tube extension point which was preventing the source from coming in under normal conditions. The cranks were straightened and a pole was used to raise the guide tube at the extension connection point and the source was retracted in normal conditions. No one was over-exposed and the boundaries were placed at such a distance that the crew and public were safe. It was a four man crew, two of whom received 0mR and the Radiographer and Assistant received 11mR and 8mR, respectively. The emergency response team members received 1mR (two of them) and 3mR (two of them)."

SECONDARY CONTAINMENT DECLARED INOPERABLE DUE TO POTENTIAL EQUIPMENT FAILURE
"At 1405 CDT, Secondary Containment differential pressure exceeded the Technical Specification limit due to a potential equipment failure. This required entry into [Limiting Condition of Operation] LCO 3.6.4.1 Condition A for Secondary Containment inoperability. An event or condition that could have prevented the fulfillment of a safety function requires an 8 hour report per 10 CFR 50.72(b)(3)(v)(C) for Control of Rad Release. Secondary Containment differential pressure was restored to greater than or equal to 0.25 inches vacuum, water gauge in accordance with plant procedures. Secondary Containment was declared operable at 1600 CDT. The issue has been entered in the Corrective Action Program and investigation of the cause is in progress.
"The NRC Senior Resident Inspector has been informed of this condition."

"CNS [Cooper Nuclear Station] is retracting the 8-hour notification made for event 54049 which occurred on May 5, 2019 at 1405 CDT. Subsequent evaluation determined that no equipment failure occurred. In addition, there were no procedure inadequacies or human performance issues identified. The indications observed were expected and part of a pre-planned evolution which included entry into a planned LCO for the Secondary Containment."
The NRC Resident Inspector has been notified.
