Fallout studies and assessment of radiological phenomena. Preliminary report. Project 32. 4 (of) Operation Plumbbob

Description: Data were obtained to evaluate the attenuation of photons, emitted from a fallout field, due to the surface roughness of the terrain. A study was made to determine the effect of the shot tower on the fallout material. Particles for comparison were collected from two detonations of equal scaled height, one tower supported and the other balloon supported. Data on time-dependent phenomena were recorded, as were physical characteristics of the fallout material. The use of small balloons as instrume… more

Definitive Scope of a Facility for E-Metal Product Segregation at the UO{sub 3} Plant Project CG-767

Description: E-Metal production is scheduled to start through the UO{sub 3} Plant in July of 1958. E-Metal is defined in HW-46138 as uranium metal enriched with U-235 to a level selected to be always-safe for non-metallic uranium forms, i.e. for compounds encountered during solvent extraction or calcination. Currently E-metal as selected contains 0.94% U-235 prior to irradiation. Planning of a segregation facility requires that the mixing of E-Metal with normal uranium be minimized, thereby preventing costl… more

Results of experimental tests simulating supply pressure decrease in a K process tube

Description: Simultaneous reduction of coolant to several or all reactor tubes raises concern not only for the adequacy of protection in the individual process tube but also the reactor as a whole. In event of such flow reduction, the heat generation does not decrease until at least 1.4 seconds have elapsed following the accident. Thus, the water temperature from each tube will rise, and result in an increase in the bulk water temperature. If the increase in bulk water temperature is such that saturation te… more

Results of heat decay test

Description: During the outages of 9-28-57 and 10-14-57 a test was performed at KW-Reactor to evaluate conditions present during front nozzle replacement programs. The intent of the test was to prove that backflow from the rear crossheader would provide sufficient cooling to prevent slug damage under the following conditions: 1. The reactor has been shut-down at least eight hours. 2. The headers which supply rows of nozzles to be replaced are valved to the relief riser on the rear, and throttled to a header… more

Spallation-Fission Competition in Heaviest Elements; HeliumIon-Induced Reactions in Uranium Isotopes

Description: A radiochemical study of fission and spallation products produced by bombardment of U{sup 233}, U{sup 235}, and U{sup 238} with 18-46 Mev helium ions has been made. As in the case of similar studies using isotopes of plutonium as targets, most of the reaction cross section is taken up by fission. Also, the pronounced increase of the total cross section for ({alpha},xn) reactions with increasing mass number of the target that was observed for plutonium targets is observed for uranium targets.

A LITERATURE SURVEY ON THE APPLICABILITY OF STEADY-STATE HEAT-TRANSFER COEFFICIENTS TO TRANSIENTS IN POWER OR IN FLOW WITH SINGLE-PHASE FLOW AND WITH TWO-PHASE FLOW

Description: A survey of all the known literature on the subject is presented. This survey consists of four parts amd two appendices, namely: response of single- phase-fluid forced-convection heat transfer to a rapid change of velocity, response of single-phase-fluid forced-convection heat transfer to a rapid change of temperature of the surface or of the incoming fluid, response of single- phasefluid free-convection heat transfer to a rapid change of the surface temperature or of the heat flux through the … more

LONGITUDINAL DISPERSION IN SOLVENT-EXTRACTION COLUMNS: PECLET NUMBERS FOR ORDERED AND RANDOM PACKINGS

Description: Dispersion phenomena in packed beds in both axial and radial directions were studied to provide basic data for extraction-tower design. Nine different beds were used, involving regular and random arrangements of spheres, and random arrangements of Raschig rings and Intalox saddles. For one-phase flow a wide range of Reynolds numbers was used (5 to 2000), covering regions of laminar, transition, and turbulent flow. For the axial Peclet number, different constant values were found in the turbulen… more

THE EFFECT OF EPINEPHRINE ON SERUM LIPOPROTEINS

Description: Epinephrine injection has been shown to produce a two and three fold increase of the higher Sf classes of serum lipoproteins in the rabbit. The previously observed elevation of serum lipids was confirmed. The hyperlipoproteinemia following epinephrine injection appears about the same time as in certain conditions of stress. (auth)

An X-Ray Spectrometric Method for Determination of Plutonium in Solution

Description: It is shown that the method of x-ray emission spectrometry can be extended advantageously to the determination of plutonium in solution, Since K and L x-ray emission from the elements of higher atomic number is not measurably influenced by valence state of the emitting atom or ion, this physical method is especially attractive for elements such as plutonium whose chemistry is intricate and whose chemical analysis is complicated by several valence states existing in solution. Nor is it affected … more

The EBR-I Meltdown--Physical and Metallurgical Changes in the Core. Final Report--Metallurgy Program 7.2.18

Description: As a result of the partial meltdown which occurred in EBR-1 on November 29, 1955, it was necessary to remove the core assembly from the reactor and to separate the enriched fuel section from upper and lower unenriched blanket sections. A temporary cave was constructed on top of the reactor in order to remove the core assembly, and at this time about one-fourth of the fuel elements were removed. In order to perform further disassembly operations under less hazardous conditions, the core assembly… more

Ultrasonics for Radioactive Decontamination

Description: Tests have been run to determine in a preliminary fashion whether ultrasonic vibration would be effective in removing mixed radioactive deposits from the inside surface of steel pipes in a heat exchanger. Different frequencies (20 KC/S, l000 KC/S) have been used at the maximum power levels conveniently attainable. Different liquids were compared for cleaning effectiveness, with and without ultrasonics. Mild stirring of water bath at room temperature produced virtually no cleaning effect on the … more
