100-B Area flow analysis

Description: Results of experimental programs indicate that it might be desirable in the future to modify the existing reactors by replacing the aluminum process tubes with tubes made of a zirconium alloy. The zirconium tubes would be more corrosion resistant than the aluminum ones and would also be stronger at higher temperatures. These new tubes would have the same outer diameter as the present tubes (for ease of handling and in order to provide adequate graphite cooling) but would have a thinner wall (si… more

The Effects of Nuclear Weapons

Description: This handbook prepared by the Armed Forces Special Weapons Project of the Department of Defense in coordination with other cognizant government agencies and published by the United States Atomic Energy Commission, is a comprehensive summary of current knowledge on the effects of nuclear weapons. The effects information contained herein is calculated for yields up to 20 megatons and the scaling laws for hypothetically extending the calculations beyond this limit are given. The figure of 20 megat… more

ISOTOPIC EQUILIBRIA OF NITROSYL CHLORIDE

Description: The electrolytic solvent characteristics of liquid nitrosyl chloride and general consideration of the factors affecting suitability of a system for isotope separation suggest that exchange reactions of NOCl might provide an interesting and useful means for the separation of the stable isotopes of nitrogen or of chlorine, or of both in a simultaneous process. Vibrational frequencies of isotope substituted NOCl molecules are calculated and used to estimate equilibrium constants for exchange of ni… more

Weak Interactions

Description: Experimental results on the non-conservation of parity and charge conservation in weak interactions are reviewed. The two-component theory of the neutrino is discussed. Lepton reactions are examined under the assumption of the law of conservation of leptons and that the neutrino is described by a two- component theory. From the results of this examination, the universal Fermi interactions are analyzed. Although reactions involving the neutrino can be described, the same is not true of reactions… more

Fast-Period Reactor Safety Fuse Tests

Description: The combination of an effective fuse with a sensitive trigger is investigated. Tests conducted with two types of fuse, the annular-passage and the control-rod-type fuse, are described and analyzed. Appendixes present the methods of analysis and calculation, an analysis of fuse performance, and a summary of alternative fuse trigger and fuse system designs, with methods for adaption of fuses to power reactors.

Mass Transfer in Low Velocity Gas Streams

Description: Experimental studies of the mixing of coaxial streams of carbon dioxide and air at ambient temperature and atmospheric pres sure were made at Reynold numbers of cal, 4-inch galvanized iron pipe. Carbon dioxide was introduced into the center of an air stream free of moisture and carbon dioxide by means of an injection tube which extended the full length of a calming section 14 feet 4 inches long. Radial concentration profiles of carbon dioxide were measured at three positions downstream. Gas sam… more

SPACE PLOTS OF PRESSURE, DENSITY AND PARTICLE VELOCITY FOR THE BLAST WAVE FROM A POINT SOURCE IN AIR

Description: Supplement to AECU-3517, (RM-l824-AECl. Graphs of pressure, density and particle velocity versus radius at specified times throughout the course of an explosion in air originating from an instantaneous release of energy at a point are presented. These curves are basic to the results and analysis reported in RAND Research Memorandum RM-l824-AEC and are published as supplementary reference data for those who have occasion to require more information or detail than is presented in that report.

DEVELOPMENT OF A BATCH PROCESS FOR THE PRODUCTION OF A ZrO$sub 2$-UO$sub 2$ SOLID SOLUTION

Description: A batch process on the 2 kg scale was developed for the production of ZrO/sub 2/--UO/sub 2/ solid solution in the weight proportion of about 4 to 1. The product is tetragonal ZrO/sub 2/-- UO/sub 2/ solution, with no UO/sub 2/ lines showing on the x-ray powder diffraction patterns. The solid solution is prepared from a precipitate of Zr(OH)/sub 4/-- (NH/sub 4/)/sub 2/U /sub 2O/sub 7/ which is filtered, dried, milled, screened to minus 325 mesh, and heated at 9OO deg C in H/sub 2/ for 4 hours. Th… more

Analysis of Stresses and Deflections in Top Support Grid, PWR Reactor. Final Report

Description: The top grid of the PWR reactor core assembly is treated as a simply supported circular plate. The theory of plate is applied to the grid umder mechanical loads. The thermal stress problem is analyzed by treating the plate as under combined action of a laterally distributed load and forces in the middle plane of the plate. The load distribution is calculated from the temperature variation over the grid. The thermal stress problem then is equivalent to two problems: one, of bendimg of plate; and… more

CHARACTERISTICS OF THE SOLID STATE TRANSFORMATIONS IN-URANIUM

Description: The purpose of the investigation was to determine the temperature dependence of the lattice parameters of U from room temperature to the melting point and to provide experimental data on the general characteristics and kinetics of the allotropic transformations in U. Toward this end high-temperature x-ray diffraction, electrical resistance, and sonic experimental techniques were employed. The data presented are interpreted in terms of the known physical, mechanical, and structural properties of… more
