A study of spontaneous ignition of metals /

This report describes a study of the reactions occurring in the spontaneous ignition of zirconium and titanium (and their alloys), with emphasis on the former. Conditions required for spontaneous ignition, including the effects of certain impurities, surface conditions, and composition of the atmosphere around the metal were investigated. In addition, the mechanism of ignition was studied by following the thermal history of the reactions during the first few milliseconds.

Radiation application and fission product utilization : a bibliography of selected unclassified literature /

"Office of Isotopes Development, U.S. Atomic Energy Commission."

Radioisotopes in agriculture : animal husbandry, fertilizer uptake, plant physiology, photosynthesis, and entomology : a selected bibliography /

This annotated bibliography contains 148 selected references on the uses of radioactive and stable isotopes in animal husbandry and in studies of fertilizer uptake by plants, plant physiology, photosynthesis, and entomology. These references were selected from scientific journals published during the period 1957-1958. Subject and author indexes and a list of the periodicals from which the references were selected are included.

Titanium metallurgy : a bibliography of unclassified report literature /

"TID-3039(Suppl. 1); Subject Category: Metallurgy and ceramics."

Feed materials : a bibliography of classified report literature /

"'Feed materials' refers to U metal, fabricated into fuel elements but not clad, and UF₆, both normal isotopic content, suitable for introduction into Pu-production reactors or gaseous diffusion cascades."

Reprocessing of irradiated fission reactor fuel and breeding materials : an annotated bibliography of selected report literature /

"Chemistry--Separation process for plutonium and uranium."

Graphite : a selected bibliography /

This compilation contains 958 references to report and published literature. The references pertain primarily to reactor grade graphite, although information on the manufacture and uses of graphite in other fields is included. The references were selected from Nuclear Science Abstracts (NSA), covering the period 1948 through mid-1961. Subject, author, and availability indexes are provided.

Evaluation of Horizons, Inc. Th metal powder : progress report no. 1 for February 18, 1954-March 4, 1954 /

Three samples of thorium powder as supplied by Horizons, Inc. of Cleveland, Ohio were compared. The powder was processed entirely without the use of protective atmospheres with the exception of the sintering which was performed in a tank argon atmosphere with a dew point of approximately -80°C and the hot-pressing which was carried out in vacuum. The equipment and procedures used for cold-pressing and sintering were identical to those used in the evaluation of Sylvania produced thorium powders. The hot-pressing was done with standard uranium hot-pressing equipment.
