Incident Reports
During a plant shutdown in Thorp Plutonium Finishing Line (TPFL) a number of proof tests were suspended and subsequently reinstated, pending TPFL plant restart.
Following a review by the Maintenance Management System Department, an anomaly was found regarding outstanding suspended maintenance.
Of the 10 items of the equipment that had been suspended, no work orders were found for five of the proof tests, meaning that the plant had been operated without valid proof tests being in place for the affected plant items.
Nobody was injured or placed in any danger as a result. The event has been classified as below the International Nuclear Event Scale. |
