Methods of Opacity Calculations

Methods of Opacity Calculations

Date: 1949
Creator: Mayer, Harris
Description: "Methods for calculating the opacity of materials at high temperatures are discussed in this report. Minor improvements are outlined for the treatment of continuous absorption processes, and a small error usually made in treating the scattering process is corrected. In contrast to all previous calculations of opacity, the effect of line absorption is carefully examined, for it may well be the dominant process under certain conditions of temperature and density. Detailed methods for calculating the line absorption contribution are, therefore, developed. To illustrate the principles involved, the opacity of pure iron at a temperature of 1000 volts and normal density is worked out in detail" (p. ii).

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.
