From abstract: "This report describes a functional mercury vapor detector which is a portable, self-contained, survey instrument, and had a minimum range from zero to two-tenths milligram of mercury per cubic meter of air."

Preface: The Fuel Elements Conference held in Paris, France, November 18 to 23, 1957, under the joint sponsorship of the U.S. Atomic Energy Commission and the French Commissarat à l'Energie Atomique (CEA), provided an intensive review of fuel-element fabrication practices and behavior of fuel elements under in-pile irradiation and when subjected to corrosive media.

This report records the study of the geology and uranium deposits of Haiwee Ridge, Inyo County, California, on the west flank of the Coso Mountains.

Introduction: This study was made in conjunction with a core drilling program designed to trace ore trends from existing mines eastward under deeper cover. The exploration drilling covered an area of about 1 square mile. The results of previous drilling by the Commission, which covered an additional 10 square miles, have been incorporated in this report.

A report about the fabrication of dummy fuel-pls assemblies which are to be used in the engineering test loop at the MTR.

Technical report was prepared by the Health and Safety Laboratory (HASL) with the objective of presenting a current picture of the Strontium Program. Abstract: Strontium 90 levels in fallout, milk, canned fish and tap water are summarized for data available up to February 30, 1958. Original data submitted during the month of February is included as an appendix. Data are presented to show the amount of Strontium 90 in fallout at sampling stations within and outside the United States.

It was suggested that radon concentrations in air and potassium fertilizers on the ground contribute appreciably to natural background radiation levels. The effect on natural background gamma radiation from radon and its associated daughters in equilibrium and from potassium in fertilizers has been calculated and found to be negligible. Background radiation intensities have been assumed to be on the order of 10 [mu]rad/hr.

From abstract: "The distribution of uranyl nitrate was measured from aluminum nitrate and nitric acid solutions into diluted tri-n-butyl phosphate. This information is useful for designing solvent extraction processes for recovery of uranium from aluminum nitrate or nitric acid solutions."

Pathfinder atomic power plant progress report.

From abstract: "The economic factors of chemical processing of the fuel and blanket from liquid bismuth fuel reactors are described and evaluated."

From introduction: "This report provides background information regarding the study results presented in the first volume of this report and provides information resulting from the studies made on the gas cooled reactor concept."

Study of factors, such as the average particle size and particle-size distribution, which affect the fluidization properties of uranium trioxide powders.

Report containing documentation of projects undertaken by the multiple branches of the Health and Safety Division of the Idaho Operations Office at the Nuclear Reactor Testing Station (NRTS).

Describing and comparing the uranium deposits in the Morrison formation, except those of the Ambrosia Lake locality.
