"[10 CFR 21.21(4)(ii)- Identification of the facility, the activity, or the basic component supplied for such facility or such activity within the U.S. which fails to comply or contains a defect:] 48Y Cylinder no.1122/0690 containing 12,155.5 kg of UF6 supplied to [ United States Enrichment Corporation (USEC)] by BNFL Fuel for enrichment."
"[10 CFR 21.21(4)(iii)-Identification cf the firm constructing the facility or supplying the basic component which fails to comply or contains a defect:] Cylinder manufactured by Staveley's Limited, Manchester, England in 1978.

"[10 CFR 21.21(4)(iv)- Nature of the defect or failure to comply and the safety hazard which is created or could be cr:ated by such defect or failure to comply:] The certified water capacity stamped on the cylinder as part of the name plate data is less than the minimum capacity specified in ANSI N14.1, Table 1, standard cylinder data for a 48Y cylinder. [The] required minimum capacity [is) 142.7 ft$[, and the] actual certified water capacity [is] 4,019 kg; equivalent to.142.1 ft*. The cylinder, in its current condition, represents no safety hazard since the actual contents of 2,155.5 kg of UFO still allows a cylinder ullage of 7.2%. The cylinder has the potential to be overfilled if the normal maximum fill limit for a 453Y was reached (12,501 kg of UF6 as specified in ANSI N14.1)."

36273 Staveleys in 1978. All other 48Y Type Cylinders 1122/0600 to 1122/0707 inclusive, numbering 107, are located on lic nsed sites in the UK."
"[10 CFR 21.21(4)(vii)- The corrective action which has been, is being, or will be taken; the name of the individual or organization responsible for the action; and the length of time that has been or will be taken to complete the action:] Having established that cylirider 1122/0690 is safe to feed; it is proposed to discuss with USEC the possibility of proceeding with the feed to their diffusion plant, as planned. Alternatively, should USEC be unwilling to proceed then concession will be sought to transfer the cylinder back to BNFL in the UK."
"Once emptied, the cylinder will be removed from service to prevent any possibility of a re-occurrence."
"Th3 Head of Site at BNFl. Springfields has commissioned a Working Party, which includes an independent senior engineer, independent selior operations manager, and standards / surveillance engineers."
"ThD Working Party:
a) Has already independently verified that there are no other under capacity cylinders located in the U.S.;
b) Will independently verify whether or not any other BNFL cylinders are under capacity; c) In the event that the independent verification does reveal any further such defective cylinders, willinitiate cppropriate action to remove such cylinders from service; d) Will monitor the implementation of any such. actions through to completion; e) [Has] already examined and modified BNFL's cylinder filling procedures to prevent an under capacity cylinder from being filled in the future; [and]
f) [Is] in the process of reviewing our cylinder purchase specification to prevent any further under capacity cylinders from being supplied."
