Cascade: a review of heat transport and plant design issues

Description: A conceptual heat transfer loop for Cascade, a centrifugal-action solid-breeder reaction chamber, has been investigated and results are presented. The Cascade concept, a double-cone-shaped reaction chamber, rotates along its horizontal axis. Solid Li/sub 2/O or other lithium-ceramic granules are injected tangentially through each end of the chamber. The granules cascade axially from the smaller radii at the ends to the larger radius at the center, where they are ejected into a stationary granul… more

Measurements of satellite refrigerator compressor power consumption and efficiency

Description: Each of the thirty compressors installed around the ring and at switchyard is an oil-injected, two-stage, Mycom screw compressor, driven by either a 350 hp or 400 hp motor. The reader is referred to TM1198 by John Satti for a detailed description of these compressors and the associated equipment. Since the power consumed by these compressors is a major operating expense for our accelerator, we were interested in measuring the power consumption and efficiency of our compressors. Two compressors … more

Radiation doses in granite around emplacement holes in the Spent Fuel Test - Climax. Final report

Description: Final comparisons are made between measured and calculated radiation doses around the holes in which the spent fuel was emplaced in the Spent Fuel Test - Climax. Neutron doses were found to be negligible compared with gamma doses. Good agreement was found between the doses predicted by Monte Carlo calculations and those measured by short-exposure thermoluminescence dosimetry. Poor agreement was found between the calculational results and doses measured by exposure of LiF optical-absorption-type… more

EP-toxicity testing of mercury removal resin grout

Description: To determine which category a waste will fit into, the EPA requires a classification test. The test, EP-toxicity, consists of a physical integrity test followed by an extraction. For the case of the mercury removal resin grout, the mercury concentration in the extract cannot exceed 0.2 mg/L if the waste is to be classified as ``solid waste.`` Otherwise, the waste is classified as ``hazardous.`` Simulated process solutions were used to load the mercury removal resin. The resin was solidified wit… more

MOD silver metallization for photovoltaics. Quarterly technical report, March 1, 1984-May 31, 1984. [Metalloorganic deposition]

Description: It was demonstrated that the nature of the initial solvent used to extract the silver neodecanoate during synthesis or to render it into solution for ink formulation has a profound influence on fired film properties. The lower the boiling point of the initial solvent, the more of it was removed during rotary vacuum evaporation, and the less effect it had on fired film properties. Benzene and tetrahydrofuran were superior to xylene and toluene, and inks which used them in their preparation produ… more

The solubility of uranium hexafluoride in perfluoroethers

Description: The polyperfluoroethers are compatible with uranium hexafluoride (UF/sub 6/) and are suitable for use in diffusion pumps and in mechanical vacuum pumps which rely on oil as both the lubricant and the seal. The UF/sub 6/ is soluble in all fluids with which it is compatible. Because a number of vacuum pumps in the BOP facilities of the GCEP plant employ these perfluoroether oils as the working fluid and have oil chambers which are large, questions have been raised as to the relationships governin… more

Stress studies in EFG. Quarterly progress report, January 1, 1984-March 31, 1984

Description: Four-point bending studies have been continued to compare primary creep response of FZ and CZ silicon above 1200/sup 0/C. Results suggest that silicon can be treated as a completely plastic solid in the temperature range 1200 to 1400/sup 0/C in its response to thermal stress generated during sheet growth. In the stress range of 5 to 15 MPa, the strain rate dependence on stress is epsilon approx. sigma/sup 10/, and appears to be essentially temperature independent. Work is underway to compare st… more

Displacement Damage in the First Structural Wall of an Inertial Confinement Fusion Reactor: Dependence on Blanket Design

Description: In this study we investigate how the design of the neutron blanket effects the displacement damage rate in the first structural wall (FSW) of an Inertial Confinement Fusion (ICF) reactor. Two generic configurations are examined; in the first, the steel wall is directly exposed to the fusion neutrons, whereas in the second, the steel wall is protected by inner blanket of lithium with an effective thickness of 1-m. The latter represents a HYLIFE-type design, which has been shown to have displacem… more

Investigation of non-intrusive radiometer for entrained gasifier temperature measurement. First quarterly report, October 30, 1983-January 30, 1984

Description: The emphasis during the first quarter has been directed toward evaluating radiometric approaches to find the optimum technique to measure temperature in an entrained gasifier environment. In this regard, it was concluded that while total radiation measurements were helpful in providing designers with total radiation loads to hardware, it was not acceptable as a means of measuring temperature for the gas/particle environment considered. To make the temperature measurements, one, two, and three l… more

Modification of the code BEAMCORR, and some simulation results of the magnet and achromat misalignments for the SLC South Arc

Description: An important decision has been made regarding the correction scheme for the arcs leading to the adoption of the so called scheme I. In this scheme the beam position data are collected from single-plane x and y Beam Position Monitors (BPMs), which are placed in the drift spaces adjacent to the downstream D- and F-magnets correspondingly. Similarly, single-plane x and y correctors are used for moving the upstream end of the corresponding magnets. In the present simulation this scheme is used excl… more

A technical and economic evaluation of thermal spallation drilling technology

Description: Thermal spallation of rock may be defined as a type of progressive rock failure caused by the creation of thermal stresses induced by a sudden application of heat from a high temperature source. This technology is applicable to only certain types of hard rock, such as dolomite, taconite, and granite. In 1981 and 1982, the deepest holes ever drilled by this process were drilled in granite to depths of 1086 feet and 425 feet respectively. Penetration rates at the bottom of the deeper hole reached… more

Composite-bed reactor for upgrading coal-derived liquids. Quarterly report No. 3, April 1-June 30, 1984

Description: Five experimental runs were conducted as a part of the temperature and catalyst zoned concept. These experiments were conducted at 10.3 MPa (1500 psig), with the bottom zone reactor at 400/sup 0/C (752/sup 0/F), LHST of 1.9 h, with 20% (wt) of the catalyst in the top zone and utilizing a variable temperature in the top zone 400 to 500/sup 0/C (752 to 932/sup 0/F). Excessive reactor plugging occurred when the top zone was operated at 500/sup 0/C (932/sup 0/F). This suggests an upper limit when u… more

Improved seal for geothermal drill bit. Final technical report

Description: Each of the two field test bits showed some promise though their performances were less than commercially acceptable. The Ohio test bit ran just over 3000 feet where about 4000 is considered a good run but it was noted that a Varel bit of the same type having a standard O ring seal was completely worn out after 8-1/2 hours (1750 feet drilled). The Texas test bit had good seal-bearing life but was the wrong cutting structure type for the formation being drilled and the penetration rate was low.
