Circumventing chloride ion trouble Columbia River water

This report contains data acquired during sampling of the Columbia River water on March 26, 1945. Topics of discussion include; the elevation of chlorine levels from 4 ppm to 20 ppm, what steps should be taken to remediate the problem, and the various processes that were taken into consideration for the clean up of this chlorine. Separation processes considered include; ion exchange, distillation, precipitation, heat exchange, and recirculation through a cooling tower.

The Production of Uranium Metal by Metal Hydrides Incorporated (open access)

The Production of Uranium Metal by Metal Hydrides Incorporated

Metal Hydrides Incorporated was a pioneer in the production of uranium metal on a commercial scale and supplied it to all the laboratories interested in the original research, before other methods for its production were developed. Metal Hydrides Inc. supplied the major part of the metal for the construction of the first experimental pile which, on December 2, 1942, demonstrated the feasibility of the self-sustaining chain reaction and the release of atomic energy.

Production of Uranium Metal (open access)

Production of Uranium Metal

Experiments were carried out for the purpose of increasing production, efficiency, and purity of uranium metal. The electrolytic method as described by Driggs and Lilliendahl for the preparation of uranium metal was followed with but little deviation. The yield of metal at the very best was only 50%. The metal powder produced, at times, was very pyrophoric. Methods were found whereby the metal, at least in part, can be made from the oxides with an average yield of about 90%. The small amounts of sludge and slag accumulated in this modified process can readily be re-used in the electrolysis pot and, therefore, an overall yield of 96% can be obtained. Information accumulated from these experiments has been compiled in such a manner as to be readily available for factory use, for patent purposes and for future publication.

H.E.W. - 300 Area - Metal turnings - Fire hazard

This memorandum discusses means to extinguish magnesium fires in metal turnings at the Hanford Engineer Works 300 Area. The storage of metal turnings in 55 gallon drums presented a fire hazard, for which an effective means for extinguishing the fire had not been presented. This memorandum is dated July 1943. (JL)

Production of (Uranium) Tetrafluoride (open access)

Production of (Uranium) Tetrafluoride

Production of tetrafluoride for the month of April was 49,400. New equipment installed late in March operated smoothly and the production was slightly over the rated capacity of the plant. Nickel ends were welded on to the steel reactor tubes to prevent corrosion at the cover joint and possible contamination of the product with iron. The nickel ends will also save considerable repair work on the tube ends. The magnesium trays for some of the reactors are beginning to crack at the sides from frequent straightening. The trays are bent out of shape by the expansion of the product and are reshaped by hammering over a die. Some of the cracks have been repaired by welding but this is not very satisfactory because the welded trays are harder to straighten and often crack again.
