Degradation Products of Tributyl Phosphate
Abstract: "A method for determination of dibutyl phosphate in solvent streams containing tributyl phosphate is outlined. The method is based on analysis for total uranium of total phosphate after removal of uranium and phosphate in excess of that present as uranyl dibutyl phosphate. Results on plant solvent samples are presented. Difficulties with precipitation of [...] dibutyl phosphate, when fresh solvents were employed, are discussed. Small amounts of nonphosphate uranium-complexing agents were found in plant solvents. Diluent degradation is postulated as the source of these components. Emulsion-formation tendencies appeared to correlate better with concentrations of these contaminants than with dibutyl phosphate content."

Nuclear power plant 5,000 to 10,000 kilowatts
The purpose of this proposal is to present a suggested program for the development of an Aqueous Homogeneous Reactor Power Plant for the production of power in the 5000 to 10,000 kilowatt range under the terms of the Atomic Energy Commission's invitation of September 21, 1955. It envisions a research and development program prior to finalizing fabricating commitments of full scale components for the purpose of proving mechanical and hydraulic operating and chemical processing feasibility with the expectation that such preliminary effort will assure the contruction of the reactor at the lowest cost and successful operation at the earliest date. It proposes the construction of a reactor for an eventual net electrical output of ten megawatts but initially in conjunction with a five megawatt turbo-generating unit. This unit would be constructed at the site of the existing Hersey diesel generating plant of the Wolverine Electric Cooperative approximately ten miles north of Big Rapids, Michigan.

Preliminary Appraisal of Diamond-Drill Exploration in the Legin Group Area, San Miguel County, Colorado
From introduction: This preliminary report summarizes the results of the 1950 drilling in the Legin group area of San Miguel County, Colorado and gives a more complete, but preliminary, estimate of the uranium and vanadium ore reserves. When the radiometric and chemical assay data are completed, a detailed report will be transmitted.

Uranium and Phosphate in the Western Part of the Bonny Lake Mine, Polk County, Florida
From abstract: During the month of May 1950, the Davison Chemical Corporation, under contract with the Atomic Energy Commission, drilled 24 phosphate prospecting holes in the western part of the Bonny Lake mine, in the SW NW4 and the NW*SW4 sec. 32, T. 29 S., R. 24 E., Polk County, Fla. The purpose of this drilling was to obtain a comparison between tonnage and grade of uranium in the phosphate as indicated by prospecting, and the tonnage and grade of uranium in the phosphate products recovered in the mill. The results presented in this paper are based upon a study of drill cores, drill logs, gamma-ray logs, and the chemical analyses of drill-core samples.

Preliminary Report on Diamond-Drill Exploration of Parts of Blue and Moon Mesas, Mesa County, Colorado
From abstract and summary: The Blue and Moon Mesa areas are about 13 miles southeast of Gateway, Mesa County, Colo. Total production of carnotite ore from the Blue and Moon Mesa areas has been about 1,000 short tons that averaged about 0.25 percent U30Oand 1.75 percent V205. Most of this production was obtained from 1940 to 1943 and in 1949. The U. S. Geological Survey explored the northern parts of these areas by diamond drilling between August 9 and December 14, 1950. The Survey drilled 113 holes, totalling 16,039 feet. This drilling was mostly wide-spaced and was done to obtain geologic information.

P Division monthly report, January 1950
This progress report discusses the activities of the P Division for the month of January 1950. The B, D, F and H pilan operated throughout the month except for outages listed under Area Activities. Power levels were as follow: B pile -- 275 megawatts (MW) D pile -- 305 MW, F pile -- 275 MW increased to 305 MW during the month, and H pile -- 275 MW increased to 330 MW during the month. The piles operated with a time operated'' efficiency of 88.8%. A total of 53.07 tons of metal at an average of 91.2% of the current goal concentration was discharged from the piles during the month. A new record canning yield of 93.9% for 4 inch canned slugs was established during January.

Radioactive debris from operations Tumbler and Snapper: observations beyond 200 miles from the test site. Part II
The results of the fall-out monitoring program at fixed stations more than 200 miles from the test site following the series of atomic tests in Nevada during the spring of 1952 are shown in a series of maps. Trajectories of debris from the individual bursts are given, together with a discussion of meteorological phenomena associated with the transport of atomic debris.

Blast biology: a study of the primary and tertiary effects of blast in open underground protective shelters. Project 33. 1 of Operation Plumbbob
Dogs, pigs, rabbits, guinea pigs, and mice were exposed to nuclear detonations in two open underground partitioned shelters. The shelters were of similar construction, and each was exposed to separate detonations. Each inner chamber filled through its own orifice; thus four separate pressure environments were obtained. An aerodynamic mound was placed over the escape hatch of each structure to determine its effect on the pressure-curve shape inside the chamber. In one test a sieve plate bolted across the top of the mound was evaluated. Wind protective baffles of solid plate and of heavy wire screen were installed in the shelters to compare primary and tertiary blast effects on dogs. The shelters also contained static and dynamic pressure gages, radiation detectors, telemetering devices, and, in one test, air-temperature measuring instruments, dust-collecting trays, and eight pigs for the biological assessment of thermal effects. One dog was severely injured from tertiary blast effects associated with a maximal dynamic pressure (Q) of 10.5 psi, and one was undamaged with a maximal Q of 2 psi. Primary blast effects resulting from peak overpressures of 30.3, 25.5, 9.5, and 4.1 psi were minimal. The mortality was 19% of the mice exposed to a peak pressure of …

Unusual incident at Savannah River
On January 12, 1953, an explosion occurred in the Savannah River pilot plant which has been used since November, 1951 by du Pont personnel to train operators and to test equipment for their new Purex production plant. The explosion occurred in an evaporator in which a uranyl nitrate solution containing some organics was being concentrated to a high degree to remove nitric acid. This memorandum reviews the facts surrounding the incident as obtained from the official Preliminary Technical Report'', and by talking to du Pont personnel. These facts are interpreted as fast as possible and the current design for the Hanford Purex production plant is re-evaluated in the light of these data.
