Decomposition of Water at High Temperatures and Pressures Under Reactor Irradiation

Decomposition of Water at High Temperatures and Pressures Under Reactor Irradiation

Date: September 16, 1949
Creator: Fromm, L. W.
Description: Partial abstract: "The investigation of the high temperature and pressure dissociation of water under irradiation was undertaken by the Power Pile Division of Oak Ridge National Laboratory in an effort to determine the degree of importance of the phenomenon with respect to the design of a high temperature water-cooled power reactor. Theory and past experimentation indicate that net steady-state dissociation is determined by the rates of the dissociation and recombination reactions under the imposed conditions, the dissociation rate being essentially a function of flux and the recombination rate essentially a function of temperature" (p. 3).

Balanced Ionization Chamber for Differential Measurements of Gamma Rays

Balanced Ionization Chamber for Differential Measurements of Gamma Rays

Date: 1947
Creator: Wiegand, Clyde
Description: "The purpose of the work was to develop a method of measuring very small differences in the half lives of gamma ray emitting radioactive substances. The apparatus was then used to try to detect a difference in the half lives of Be7 metal and BeO. The results of the measurements on the two different chemical forms of beryllium will be given" (p. 1).

The Heat of Solution of Uranium Tetrachloride in Aqueous Perchloric Acid Solutions

The Heat of Solution of Uranium Tetrachloride in Aqueous Perchloric Acid Solutions

Date: August 19, 1947
Creator: Fontana, B. J.
Description: Abstract: "The heat of solution of UCl4 solid has been measured and found to change appreciably with changing concentration of H+ or ionic strength. The heat of hydrolysis of U+4 to form UOH+3 is probably of the order of +11 kcal per mole" (p. 1).

Estimation of Small Quantities of Uranium in Thorium

Estimation of Small Quantities of Uranium in Thorium

Date: 1946
Creator: Weissman, S. I. & Duffield, R. B.
Description: Abstract: "Estimation of the intensity of the uranyl fluorescence furnishes a method for the determination of quantities of uranium as low as one-half microgram of uranium in one-half illilitor of glassy phosphoric acid. The test has been used to detect directly three parts of uranium in one million parts of thorium" (p. 1).
