Treatment of Torbernite
Production of black oxide from torbernite was studied on a laboratory scale from the standpoint of uranium extraction, reagent requirements, and removal of impurities. A small portion of the material was examined for its mineral constituents, using optical properties, X-ray diffraction patterns, and chemical analysis for identification. About 50% of the material was quartz; 30% green crystals of a copper-uranium phosphate; 10% of a black mineral, which was not identified, but which appeared to be an oxide mixture of nickel, cobalt, copper, and molybdenum; and small amounts of gibbsite, laterite and feldspar. There were no lower oxides of uranium in the sample.

The trend of contamination in the air, Columbia River, rain, sanitary water, vegetation, and wastes, at the Hanford Works and vicinity for the period October, November, December 1947
This report summarizes the contamination observed at the Hanford Works and vicinity for the period October, November, and December, 1947. Trend charts showing trend of contamination for the various sampling locations are only included where a true trend can be established for the three month period; a thorough analysis of all trends will be considered in detail in the annual report from this section. The report is divided into the following topic sections: Meteorological -- dissolving data; beta contamination in the air and the radiation levels in air; alpha and beta contamination in the Columbia River; beta contamination in the rain and snow; alpha and beta contamination in drinking water; beta contamination on vegetation; and alpha and beta contamination in Hanford Wastes. An appraisal and review of all the results is considered in detail for each section. Statistical analysis is used whenever possible to determine significant values and differences in levels of contamination measured.

The trend of contamination in the air, the Columbia River, rain, sanitary water, vegetation, and wastes, at the Hanford Works for the period July, August, September 1947
This report summarizes the contamination observed at the Hanford Works and vicinity for the period July, August, and September, 1947. Daily or weekly trends for all sampling locations as included in previous reports are omitted except in those cases where a true trend can be established. Statistical analysis to determine significant values and differences is used whenever possible. The report is divided into the following topic sections: meteorological -- wind conditions; extent of beta contamination in air and radiation level in air; extent of contamination in the Columbia River; extent of beta contamination in rain; extent of alpha and beta contamination in sanitary water; extent of beta contamination on vegetation; and the extent of contamination in Hanford Wastes. An appraisal and review of all the results is considered in detail for each section.

Trip report: Argonne National Lab., Naval Reactor Division, December 12--13, 1949
This trip was spent in conferences with H. Etherington, A. Amroni, Geo. Anderson, and L.W. Fromm; and in inspection of components now being built for the Navy Test Rig which is to be installed at H Pile. Mr. Anderson believes that the entire assembly will arrive at Hanford between January 16 and 23, 1950. Much has yet to be designed and built, however. Also, certain incompatibilities with the H Pile were pointed out, and will be altered.

Trip Report, December 16--21, 1949
December 16--20, 1949 were spent in inspection of the equipment of the Naval Pilot Channel Test Rig at the Oak Ridge pile, observation of its maintenance and use, and in discussions with the test operating personnel, and members of the H.P. and pile operating divisions. December 21 was spent at the Argonne National Laboratories, Naval Reactor Division, in inspection of the test rig under construction for use at the H pile. Dr. Etherington requested that I express their desire to arrange that an Argonne scientist be at Hanford with the test rig to act in an advisory capacity, for consultation, and to prepare such reports to Argonne as they may need to call for as the test progresses.

Turbidity coagulant for Columbia River water
In this document, information about the need for a better compound to for filtering process water from the production reactors. It was found that the natural turbidity in the Columbia River was high enough to necessitate the use of a coagulant to minimize the passage of iron through filters. Tests indicated that Ferrisul was the better of the two compounds tested.

Uranium Peroxide
It was desired to investigate the precipitation of UO{sub 4} in acid solution, in order to determine the suitability of this reaction for use in the purification of uranium. A series of tests was performed to establish the conditions for precipitation of UO{sub 4}. It was found that uranium could be completely precipitated from pure uranyl sulfate solution at a pH of 2.5 to 3.5, with only silght excess of H{sub 2}O{sub 2}. The presence of sodium sulfate interferred with complete precipitation. It was established that vanadium was preferentially oxidized, when present.
