Work has continued on high temperature methods for processing irradiated U fuel. Additional results have been obtained with fused halide treatment, solid scavengers, and direct Pu distillation. With fused fluorides about 95% of the Pu was removed from a U sample,whiletreatment of U with HCl gas removed almost all the Pu and many fission products. Treatment of molten U with UO/sub 2/ removed a substantial fraction of the fission products without removing Fu. Uranium carbide treatment results were similar to the oxide but not as effective. A small scale distillation of Pu from U showed that Raoult's law is obeyed. (auth)

This document presents a summary of work and progress at the Hanford Engineer Works for March 1954. The report is divided into sections by department. A plant wide general summary is included at the beginning of the report, after which the departmental summaries begin. The Manufacturing Department reports plant statistics, and summaries for the Metal Preparation, Reactor and Separation sections. The Engineering Department`s section summaries work for the Technical, Design, and Project Sections. Costs for the various departments are presented in the Financial Department`s summary. The Medical, Radiological Sciences, Utilities and General Services, Employee and Public Relations, and Community Real Estate and Service departments have sections presenting their monthly statistics, work, progress, and summaries.
