Hunt Valve Company, Inc., a valve manufacturer and vendor, reports
finding cracks on the hex flats of packing nuts used with UF-6 valves
manufactured under contract to the United States Enrichment Corporation,
Inc. (USEC). The vendor states that the total number of valves included
in these shipments is 2,300 of which 1,300 are known to be from the
affected heat codes (see table below). All other inventory is accounted
for and isolated. These valves were located at USEC and are being
returned to the vendor for replacement nuts.

Upon notification from the vendor, USEC did a 100 percent check of the
cylinders on-site at Paducah and Portsmouth. Paducah did not find any
cylinders which contained the faulty valves. Portsmouth found one and has
taken the necessary steps to ensure safety. The vendor is currently
investigating the source of the defect.
