Description

In the defense community, certain uranium-alloy components have been manufactured by methods which generate large quantities of uranium bearing waste. Our estimates show that these components can be fabricated by vapor deposition and reduce waste generation by more than an order of magnitude. We present results from a series of uranium-alloy vapor deposition tests designed to produce samples of free-standing structures. Both flat plate and cylindrical shells were produced. The deposits were fully dense, defect free and displayed a high quality surface finish. The uranium-alloy was co-evaporated from a single source. Bulk chemistry specifications for the material were met, although ... continued below

The deposits were fully dense, defect free and displayed a high quality surface finish. The uranium-alloy was co-evaporated from a single source. Bulk chemistry specifications for the material were met, although some residual variation in chemistry was observed in sample cross sections. After heat treatment, the vapor deposited samples exhibited tensile properties similar to conventional ingot processed material.
