Results of U.S. Geological Survey Exploration for Uranium-Vanadium Deposits in the Club Mesa Area, Uravan District, Montrose County, Colorado

Description: From introduction: This report summarizes some of the results of U. S. Geological Survey investigations in the Club Mesa area and presents a compilation of available geologic data that would be helpful in future exploration. Detailed geologic logs of U. S. Geological Survey holes drilled in the Club Mesa area on public land that is no longer withdrawn from mineral entry are on open file for public inspection in the U. S. Geological Survey office, Grand Junction, Colorado.

Experimental Evaluation of Swirl Can Elements for Hydrogen Fuel Combustor

Description: Memorandum presenting a study of the performance of swirl-can combustor elements for an experimental short-length turbojet combustor utilizing hydrogen fuel at high-altitude operating conditions. Fuel was injected into each element through a tangential, sonic orifice that created a swirling fuel-air mixture within each element. Results regarding combustor blowout, combustion efficiency, outlet temperature distribution, and preliminary performance of multielement combustor are provided.

Flowsheet No. 1: Cesium isolation and packaging

Description: An engineering flowsheet has been prepared for the conversion of an aqueous slurry of cesium-zinc-ferrocyanide into a dry cesium chloride product by the calcination process. Flowsheet No. 1 defines a six-step batch-type calcination operation for processing the slurry into a dry powder for offsite shipment in bulk containers. Some of the advantages to this process are as follows: Product losses are expected to be small, estimated to be less than 0.03 percent; the equipment required to process a … more

Re-evaluation of Ball 3X Recovery System improvements, 105-B, D, DR, F, and H

Description: Since the installation of Ball 3X equipment on the older reactors, several inadvertent ball drops have been experienced, many of which have required considerable recovery time. Furthermore, it is very probable that these recovery times be significantly increased subsequent to the proposed installation of air accelerated vertical safety rods. Because of this, interest has been expressed by reactor operations personnel toward provision of a ball recovery system which would substantially reduce th… more

Summary of K Reactor outlet temperature limits

Description: The purpose of this report is to summarize all actual and potential power level limits under which the K Reactors may be forced to operate during the next year. In addition, a summary of the methods being followed to eliminate each is to be discussed along with a graphical presentation of the relationship of the various limits. For the purpose of this report, it was assumed that all power levels will be attainable from a physics aspect since these problems are discussed elsewhere. It is not the… more

Interim report on tests simulating the transient response of individual process tubes to inadvertent plugging

Description: Current Panellit protection procedures, termed instability limits, come from calculations based on steady state experiments. However, the actual conditions in a process tube following a plugging occurrence sufficient to cause unstable flow are transient rather than steady state, and cannot be determined with great precision except by transient state experimentation. As a result, a program was initiated by the thermal Hydraulics Operation of HLO to perform a series of transient heat transfer exp… more

Fabrication of Dispersed Uranium Fuel Elements Using Powder-Metallurgy Techniques

Description: Fabrication techniques for producing dispersion fuel elements with cores of 30 volume per cent of UC, U/sub 2/Ti, U/sub 3/Si, or U/sub 6/Ni dispersed in Zircaloy 2 and 30 volume per cent of UC or UN dispersed in Type 18-8 stainless steel have been investigated. Roll-clad plate-type elements of all these compositions may be fabricated by powdermetallurgy methods in such a manner that good core-tocladding bonds and cores with uniform dispersions of discrete uranium- compound particles are obtaine… more
