Design and test of a thermosiphon evaporator for acid-deficient uranyl nitrate

Description: The reference process to recycle /sup 233/U to HTGRs begins with the receipt of the /sup 233/UO/sub 2/(NO/sub 3/)/sub 2/ product solution from a reprocessing plant, which is fed to a resin loading system. The nitrate is removed by extraction with a liquid organic amine. By adding an evaporator to remove water, a continuous, high-efficiency process for loading uranium on ion exchange resin is possible. A vertical thermosiphon evaporator was designed, fabricated, and tested with natural uranium t… more

Effects of CTR irradiation on the mechanical properties of structural materials

Description: Mechanical properties of CTR structural materials are important in determining the reliability and economics of fusion power. Furthermore, these properties are significantly affected by the high neutron flux experienced by components in the regions near the plasma of the fusion reactor. In general, irradiation hardens the material and leads to a reduction in ductility. An exception to this is in some complex engineering alloys where either hardening or softening can be observed depending on the… more

Technical and cost analysis of rock-melting systems for producing geothermal wells. [GEOWELL]

Description: The drilling of wells makes up a large fraction of the costs of geothermal energy-extraction plants, and billions of dollars for wells will be needed before geothermal energy is nationally significant. Technical and economic systems studies are summarized regarding the application of the Subterrene concept, i.e., excavating and penetrating rocks or soils by melting, to the production of deep wells such as may be used for dry hot rock or geopressurized geothermal energy-extraction systems.

Update on the development of 120-keV multi-megawatt neutral beam source

Description: The next generation of U.S. fusion experiments, which includes TFTR, MFTF, and Doublet III, will utilize neutral-beam injection for plasma heating. TFTR, for example, desires 20 MW of 120-keV deuterium atoms in pulses of 0.5-sec duration at 5-minute intervals from a total of 12 individual neutral-beam modules. A discussion is given of some of the design details of a 15-A, 120-keV, 0.5-sec ion-source module that has recently been built to test design concepts for TFTR sources, and some of the fe… more

Determination of defective particle fraction in HTGR fuels

Description: The fuel for the High-Temperature Gas-Cooled Reactor (HTGR) consists of uranium and thorium species in the form of microspheres individually encapsulated in layers of pyrolytic carbon and silicon carbide. In the characterization of these particles, an important consideration is the fraction in a particular sample that may have defective coatings which would allow the release of gaseous and metallic fission products. A method for this determination, which has been in use for almost a decade, is … more

Multipurpose laboratory test system applying CAMAC standards

Description: A flexible electronic product test and evaluation system is proposed. A system study was performed to determine how increasingly complex telemetry systems could be effectively evaluated during development and preproduction and after first production units were built. A primary requirement was that this system remain flexible with respect to configuration and mission and that it be easily maintainable. In addition, the system must be upgraded easily as old product requirements and definitions ar… more

Sodium--sulphur battery system. Annual report, May 19, 1975--May 19, 1976. [Dow Chemical U. S. A]

Description: The development of the hollow-glass-fiber sodium--sulfur battery progressed significantly. Glass fiber quality improved greatly, and the fiber spinning and assembly machinery was made capable of more uniform operation. Impurities in the sulfur, including H, C, Zn/sup + +/, and Al/sup + + +/, do not appear to affect cell lifetime, while impurities in the Na are important. The Ca and ''oxide'' contents of the Na must be held to low levels. Corrosion products of a 316 stainless steel case are harm… more
