Airborne Radioactivity Survey of the Red Desert Region, Sweetwater County, Wyoming

Description: From abstract: An airborne radioactivity survey of a selected area in the Red Desert, Sweetwater County, Wyoming, containing outcrops of radioactive lignites and shales of known surface extent and uranium content, was flown on flight lines at three levels, respectively 250, 500, and 1,000 feet above the ground and spaced at one-quarter mile intervals. Measurements from three identical dual-channel radiation detectors were simultaneously recorded to obtain data at various distances from natural … more

A Solvent Extraction Method for Neptunium (237) Analysis

Description: Technical report describing a rapid and quantitative radiochemical method for the analysis of neptunium (237). This method is based on the extraction of neptunium (IV) with thenoyl-trifluoracetone in xylene. Neptunium (237) is separated free from other alpha emitters and from non-radioactive interferences, and the method may be readily adapted to remote control. [From Abstract]

Project C-431-A Production Facility design computations on outfall structure 1900-C

Description: Project C-431-A includes the design of the C Water Plant outfall structure. This report documents design assumptions and the design of the spillway, outfall sewers, spillway chute, trash racks, walkways, stop log and trash rack slots, main sewer, and retention sewers. The spillway capacity is to be 268,000 gpm with a crest elevation at 429.0. This flow capacity is composed of flow from the 105-C Retention Basin (80,000 gpm), 105-B Retention Basin (45,000 gpm), and the 190-C Area main sewer (143… more

Production Test 105-389-P graphite sample boring from process channels. Final report

Description: The study of radiation damage to the graphite moderator is largely dependent upon the availability of graphite samples from the moderator itself. Because of the varied temperature-flux history and complicated structure of the piles, it is impossible to study the problem from the laboratory standpoint alone. The samples of greatest interest are those taken from the sections of the moderator which have received the greatest damage. However, a comprehensive study requires samples from all sections… more

Memorandum on Chemical Reactors and Reactor Hazards

Description: Two important problems in the investigation of reactor hazards are the chemical reactivity of various materials employed in reactor construction and the chracteristics of heat transfer under transient conditions, specifically heat transfer when driven by an exponentially increasing heat source (exp t/T). Although these problems are independent of each other, when studied in relation to reactor hazards they may occur in a closely coupled sequence. For example the onset of a dangerous chemical re… more

Some Comments on the Mechanism of Fission

Description: A correlation of spontaneous fission rates with Z and A is made to show that these rates depend on the nuclear type. Some suggestions as to the mechanisms are given and it is also shown how these relate to the mechanism of slow neutron and photo fission.

Carbon Dioxide Fixation by Microorganisms

Description: Resting cells of eleven microorganisms were exposed to radioactive carbon dioxide for 40 minutes. The radioactive compounds formed during this time were separated and identified by paper chromatography. Resting cells of Lactobacillus casei fixed no carbon dioxide and growing cells fixed carbon dioxide primarily in malic and aspartic acids. All of the radioactive compounds formed could have become radioactive by reversal of known decarboxylation reactions.

A Glass Still for the Evaluation of Column Packing With Uranium Hexafluoride

Description: The operating holdup and flooding rates of uranium hexafluoride, n-heptane, and perfluorodimethylcyclohexane have been studied in a glass still filled with 1/8 inch nickel Heli-Pak. The flooding rates of the latter two substances are 46.0 and 48.0 cc./min. respectively and the flooding rate for uranium hexafluoride, calculated from the Bertetti equation, is 42.9 cc./min. The operating holdups for these three substances on Heli-Pak were measured at several throughput rates up to the flooding rat… more

PROBLEMS OF LEACHING AND DIGESTION OF URANIFEROUS SLAGS. Progress report No. 2 for June 1951

Description: The volume of H/sub 2/ evolved on dissolving screened nonroasted U- bearing scrap, slag, and liner in HCl were determined; the values were found to indicate the degree of removal of metallic particles by screening. Digestions of nonroasted plant-pulverized scrap with HNO/sub 3/, NaNO/sub 3/, or Fe/sub 2/(SO/ sub 4/)/sub 3/ in HCl and with HNO/sub 3/ or NaNO/sub 3/ in H/su b 2/SO/sub 4/ were not so effective as digestion with NaClO/sub 3/ in HCl. Doubling the free acid content and addition of Fe… more

Effects of Design Details on the Fatigue Strength of 355-T6 Sand-Cast Aluminum Alloy

Description: Note presenting static and fatigue tests made on 355-T6 sand-cast plate-type aluminum-alloy specimens incorporating holes, bosses, and ribs. In the static tests, the tensile strength of the plain plate-type specimen agreed within 3 percent with the strength of separately cast test bars. Of the design details studied, the unreinforced hole was the most effective stress-raiser for fatigue lives from 10,000 to 25,000,000 cycles.
