Narrative
On june 14, 2019 at 7:15 am cdt, an electrical technician completing morning rounds discovered approximately 3 gallons of crude oil near the line 65 unit 3 pump at the donaldson station. The unit 3 pump was not running at the time the release was discovered. The edmonton control center was contacted and the pump was isolated and locked out. Additional operations personnel were dispatched to investigate the source of the release and begin cleanup of the oil from the concrete pump room floor. Small diameter piping that was welded to the underside of the pump was found to be the source of the release. Once the repair plan was finalized on june 18, 2019 it was determined that the costs would exceed the nrc reporting threshold and an external notification to the nrc was made at 9:52 am cdt (#1249253). A 48-hour update was made to the nrc on june 20. 2019 at 8:10 am cdt (#1249485). In order to repair the small diameter piping and determine the cause of the failure, the entire pump was removed from the station and sent to sulzer for repair, cleaning, and analysis. Once the pump was disassembled and inspected, it was discovered that the cause of the release was due to internal corrosion/erosion within the pump case and balance line. When the cleaning of the pump is completed, the pump will be sent back to the donaldson station for installation. It is anticipated that the pump will be operational by the end of 2019.
