On May 26,1999, USEC was informed by Siemens Power Corporation that a September 23,1998, shipment had been received from USEC with one ball lock pin disengaged. Ten ball lock pins on I
i cach package are required by the Certificate of Compliance to be engaged during UX-30 package l
shipments. The content of the involved shipment was five UX-30 packages containing cylinders of I low enriched (4.396%) uranium.
1 The cause for the ball lock pin becoming disengaged cannot be determined, however, USEC has I
revised procedure XP4-TE-UH2400, Shipping and Receiving Large UF Cylinders, to improve 6
reliability. On September 28,1998, USEC revised the procedure to add a warning note concerning ball lock pins and to provide instructions for lubrication. Subnquently, on November 16,1998, the procedure was revised once again to add a verification step and a checksheet for locking pin verification.
