BOILING RUBIDIUM AS A REACTOR COOLANT. PREPARATION OF RUBIDIUM METAL, PHYSICAL AND THERMODYNAMIC PROPERTIES, AND COMPATIBILITY WITH INCONEL

Description: Rubidium metal was investigated as a possible heattransfer medium for an aircraft reactor. The separation of rubidium from other alkali metals by ion exchange was demonstrated. Data are presented on the physical and thermodynamic properties of rubidium and corrosive effects on Inconel at elevated temperatures. It was concluded on the basis of empirical formulas that more heat can be transferred in a boiling rubidium system than in a comparable boiling water system. (C.H.)

AN ESTIMATE OF THE LAPRE POWER AND STEAM FLOW CHARACTERISTICS

Description: A method of numerical solution is developed for calculating the LAPRE (Los Alamos Power Reactor Experiment) coolant pressure drop and pcwer output with variable coolant inlet pressure, flow rate, and reactor solution temperature. The results of a series of calculations are presented that show excessive pressure drops and sonic exit flow as the flow rate is increased and the inlet pressure is decreased. Both supercritical and subcritical coolant flow regions are investignted. Reactor pcwer is sh… more

METALLURGY DIVISION SEMIANNUAL PROGRESS REPORT FOR PERIOD ENDING APRIL 10, 1954

Description: Transformation kinetics studies were started on Ag - Zr alloys. Tensile properties of Th alloys with additions of 2 and 4% Ti and varving C content were determined. The production of U - Al alloys by reduction of UO/sub 2/F/sub 2/ in a cryolite slag was demonstrated. Dynamic corrosion experiments including impact tests on commercial-purity titanium samples exposed to oxygen-preseurized UO/sub 2/SO/sub 4/ periods in excess of 500 hr indicated that no change in impact behavior occurred. Similar t… more

PREPARATION AND CONSOLIDATION OF THORIUM AND THORIUM HYDRIDE POWDERS

Description: A study was made of powder characteristics and cold compacting properties of metallic thorium, Th/sub 2/ and Th/sub 4/ powders produced from Annes billet lathe turnings. In addition a preliminary study was made of the influence of various powder processing and sintering variables on some physical properties of cold compacted bodies. The cold compacting and sintering characteristics of metallic thorium powder were generally superior to those ot the hydride powders. The thorium powder could be co… more

Separations Chemistry, Quarterly Progress Report, January-March 1954

Description: "Scale-up work on high temperature fuel recovery processes has progressed to the point where the (high temperature) vacuum furnace for several operations to the hot cells has been completed and tested under operating conditions. Small scale experiments on high temperature methods for processing molten irradiated uranium fuel have been made with spent X-10 fuel slug pieces. The results of direct Pu evaporation, treatment with fused fluorides and oxide scavenging were every similar to those fou… more

Sodium Graphite Reactor, Quarterly Progress Report, December 1953 - February 1954

Description: "Engineering pertinent to the development of the sodium-cooled, graphite-moderated type of reactor was continued. This included work on problems related to the zirconium canned moderator, low enrichment uranium fuel, sodium piping, secondary coolant system, shielding, and the control and safety elements. A large fraction of the work was devoted specifically to problems of the proposed Sodium Reactor Experiment (SRE) configuration. In this connection, an integrated effort was initiated to pre… more

Summary of High Temperature Liquid Metal, Fused Salt Pump Development Work in the Ornl-Anp Project for the Period July 1950-January 1954

Description: All of the information available on high-temperature pumps originally reported in the ANF quarterly reports is summarized. The development program was more of a seal development than a specific pump program. Frozen seals of various kinds were tried and for many commercial applications would be perfectly satisfactory. For application in a system such as the ARE, operation of the frozen seal puunp is questionable. A gas-sealed pump was developed and is expected to be entirely adequate for a syste… more

THEORY OF MULTIPLE COULOMB SCATTERING FROM EXTENDED NUCLEI

Description: Two independent methods are described for calculating the multiple scattering distribution for projected angle scattering resulting when very high energy charged particles traverse a thick scatterer. The single scattering law for projected angle scattering is taken to be the Rutherford scattering law for projected angle scattering modified at small angles by electron shielding and at large angles by a nuclear form factor F{sub n}({phi}/{phi}{sub o}) which gives the effect of the finite nuclear … more
