Electrophoretic Processes--Nuclear Aspects. Final Report for December 1, 1956-June 30, 1959. Vitro Job 2091

Description: The feasibility of the electrophoretic (electrokinetic) coating process has been demonstrated for a number of nuclear applications. The major portion of the experimental program was directed toward work which leads to: development of electrophoretic coatings which should be useful for the protection of graphite and graphite fuel elements against physical and chemical attack under reactor conditions. Several of these coatings also show promise for fission product retention; a technique for apply… more

An Estimation of the Explosion Hazard During Reprocessing of Metallic Uranium Fuel Elements Metallurgically Bonded to Zircaloy Cladding

Description: Through the years, considerable effort has been expended in studies of the explosive reactions sometimes observed in the dissolution of uranium-zirconium alloys in nitric acid. It has been shown (1) that such reactions result from the rapid oxidation of finely dived solids released by the preferential dissolution of the metallic matrix. The explosive portion of such solids has been identifies (1) as an intermetallic compound with the approximate composition UZr2. This compound, referred to as t… more

AN ESTIMATION OF THE EXPLOSION HAZARD DURING REPROCESSING OF METALLIC URANIUM FUEL ELEMENTS METALLURGICALLY BONDED TO ZIRCALOY CLADDING

Description: BS>Experimental studies were performed to define the behavior in ammonium fluoride solutions of uraniumzirconium alloys and of explosive residues isolated from such alloys. The results indicate that once the diffusion layer existing between the uranium core and the Zircaloy cladrung is exposed to such solutions, it will readily and completely dissolve, thus eliminating the possibility of this portion of the diffusion layer entering into an explosive reaction with nitric acid. Because of the pro… more

RBU: A Combined Monte Carlo Reactor-Burnup Program for the IBM 709

Description: RBU is a digital computer program for the detailed calculation of the neutron, reactivity, and isotopic history of a reactor in which relatively exact models of the geometry and physical processes are included to permit reliable pre dictions of fuel costs and reactor performance. The program uses the Monte Carlo method to obtain the fine structure of the neutron flux in three space dimensions and energy. Using this fine structure, cross sections are averaged over space and energy to obtain the … more

Respiratory Pathways in Fungi and Actinomycetes

Description: Conducted from January 1, 1956 to June 30, 1959. The major effort has been to determine if any of the various proposed methods for the analysis of the differential contribution of competing respiratory pathways can be applied reproducibly to the problem of what shifts in metabolism occur when a resting spore of a fungus begins growth. This has involved comparison of spores in different states by a variety of methods.

Off-Design Performance of Divergent Ejectors

Description: "The off-design performance of fixed- and of variable-geometry divergent ejectors was investigated. The ejectors, which were designed for turbojet operation at Mach 3, were investigated in the Mach number range of 0.8 to 2. The performance of a fixed-geometry ejector with high secondary-flow rates was competitive with that of more complex variable-geometry ejectors. Variable-geometry ejectors with compromises to reduce mechanical complexity produced performance reasonably close to that of an id… more
