Depleted uranium metal is produced from Paducah six-to-four type green salt which has been in drum storage approximately 8 to 10 years. Magnesiothermic reductions of the UF/sub 4/ are carried out in closed, but not tightly sealed, Cor-Ten steel pots which are lined with jolt-packed MgF/sub 2/ powder. The liner material is prepared from the MgF/sub 2/ slag recovered from the reductions. Firm linings are produced by jolting the powder around steel mandrels inserted into the pots. Each tamped reduction charge contains 497.5 pounds UF/sub 4/, 2.5 pounds UO/sub 3/ (previously blended into the green salt) and 78.75 pounds magnesium granules. The reductions are preheated to the point of autoignition in Rockwell electrical resistance furnaces.
