Title: PRODUCTION OF URANIUM METAL BY THE HOT WIRE TECHNIQUE. Final Report on Problem No. 215-ML-54-4, File Serial 52

Abstract

The initial research used a flow system in which H/sub 2/ and I/sub 2/ passed over crude U at 500 deg C to form Ul/sub 4/ which decomposed on a ThO/sub 2/-coated tungsten filament. The filament operated at 1500 deg C. The pure U dripped into a crucible in the cooler part of the furnace. This produced spectroscopically pure metal, and alternative designs were made to simplify operation and extend it to larger scales. One such design used a thermal gradient with the crude metal at the cool end of the tube and the pure metal at the hot end. This apparatus worked according to plan and was extremely promising. A sealed system without flow of gases was useful for theoretical studies only and established the limiting pressures for H/sub 2/. Another variation depending on a vapor phase reduction is under development. (auth)
