Laboratory Survey of Deoxidants for Uranium Chips (open access)

Laboratory Survey of Deoxidants for Uranium Chips

Summary: "Six different types of solutions of various concentrations were used to deoxidize uranium chips on a laboratory scale. None of the solutions tested appears to be more desirable than 50% nitric acid for deoxidizing uranium chip on a production scale."

Corrosion of Redox Waste Storage Tank Construction Materials (open access)

Corrosion of Redox Waste Storage Tank Construction Materials

From introduction:"It was the aim of this investigation to determine the resistance of several materials of construction to current and anticipated and anticipated Hanford separation process waste streams under specific conditions. The corrosion rates of mild steel and austenitic stainless steel and the resistance of several commercial protective coatings were established."

A Study of the Delayed Neutron Emitter, Br87 (open access)

A Study of the Delayed Neutron Emitter, Br87

Report discussing a study to determine experimentally whether a low neutron binding energy must be assigned to Kr⁸⁷ to explain the neutron emission or whether the beta-decay energy is especially high, as well as to determine the fission yield of Br⁸⁷.

The Heat of Solution of Neptunium Metal and the Heats of Formation of some Neptunium Chlorides ; A Microcalorimeter for Heat of Solution Measurements

Due to a need of precise thermodynamical and thermochemical data on these elements and their compounds for the understanding and correlation of the chemical behavior of these substances, this report measures the heat of the solution of neptunium metal and the heats of formation of the neptunium chlorides using a microcalorimeter to measure the heat.

Studies of the Metabolism of Certain Fission Products and Plutonium (open access)

Studies of the Metabolism of Certain Fission Products and Plutonium

A short survey of some of the metabolic relationships of the elements, cerium, colurbium, plutonium, strontium, yttrium, and zirconium is presented. While the results of internally deposited radium have not been investigated in these experiments, they have been extensively studies by others. Because so much is known of its biological effects, it has been included in this historical survey.

The Photoproduction of Mesons from Hydrogen (open access)

The Photoproduction of Mesons from Hydrogen

In an effort to gain information on the nature of the photon-meson and photon-nucleon interaction, a study of the artificial production of mesons by photons has been made at the Berkeley synchrotron. The major effort of this research was concentrated on a measurement of the energy and angular distribution of u+-mesons produced when the photons strike a target of liquid hydrogen. Detection of the mesons is accomplished electronically by the technique of delayed coincidence.

A Note on the Mechanism of the Formation of Alpha-Acylamino Ketones from Amino Acids

The reaction of alanine-1-C14 and phenylalanine-1-C14 with acetic anhydride in the presence of pyridine has been studied and the carboxyl group of the amino acid has been shown to be the exclusive source of carbon dioxide involved.

Oralloy Shape Factor Measurements (open access)

Oralloy Shape Factor Measurements

Measurements have been at the Pajarito remote control laboratory to determine the effect of change of shape on system reactivity for oralloy cylinders. Systems tested include cylindrical configurations with various height-to-diameter ratios ranging from slabs to rods. Each system reactivity is referred to that of a sphere in the same tamper. Reactivity tests were made on bare (untamped) Oy configurations, as well as on systems In tuballoy tampers 1.12,1.87,and 8.0 thick. The amount of reactivity change associated with a particular cylinder height-to-diameter ratio is feud to be a function of tamper thickness, and is greatest for very thin tampers.

The Reaction of Tritium and Stopcock Grease (open access)

The Reaction of Tritium and Stopcock Grease

This investigation was begun as a result of a mass spectrometric measurement of two samples of tritium which had been stored for several months in Pyrex glass bulbs using stopcocks. The first of these was originally supposed to be of extremely high isotopic and chemical purity. What was observed at this time was 1.45 H had accumulated, and that tritiated methane, CT4, was also present to the extent of 0.18%. A consistent attempt had been made in this sample to protect the gas from contact with the grease by covering the stopcock with mercury. the second sample was a composite of T2 samples of various degrees of enrichment with an isotopic analysis of 92% T. No protection had been attempted during its storage, and 0.86% CT4 to be present.
