Confirmation test for gas/slurry flow in SRC-I coal liquefaction process. Internal R and D final report

Description: The overall objective of program 12.11.1 was to provide data needed to confirm the design of the transport system, slurry heat exchangers, and slurry feed manifolds for the SRC-I Demonstration Plant. Because of lack of funds, the program was terminated before most of the work was completed. Two studies related to distribution of two-phase flow in the heat exchanger tubes were finished. A special system was designed to measure slurry concentration and flow rate in different tubes. Results showed… more

Reasons for the termination of, and DOE losses in, a geothermal demonstration powerplant project

Description: The 50-megawatt Baca geothermal demonstration powerplant project, located in northern New Mexico, was the Department of Energy's (DOE's) initial effort to demonstrate geothermal powerplant technology. The project, started in 1978, was believed to have a high probability of success, and its cost was to be shared equally with the industry participants. GAO's review showed that the project was terminated in January 1982 because sufficient geothermal steam to operate the powerplant could not be obt… more

Theoretical and experimental studies of fixed-bed coal gasification reactors. Final report

Description: A laboratory fixed-bed gasification reactor was designed and built with the objective of collecting operational data for model validation and parameter estimation. The reactor consists of a 4 inch stainless steel tube filled with coal or char. Air and steam is fed at one end of the reactor and the dynamic progress of gasification in the coal or char bed is observed through thermocouples mounted at various radial and axial locations. Product gas compositions are also monitored as a function of t… more

Hot dry rock geothermal energy development program. Annual report, fiscal year 1982

Description: Emphasis in the Hot Dry Rock Program was on development of methods to produce the hydraulic fractures required to connect the deep, inclined wells of the Phase II system at Fenton Hill. Environmental surveillance, instrument development, laboratory and modeling studies, and other supporting activities were continued. After two unsuccessful attempts to fracture hydraulically through inflatable packers, formation breakdown was produced in an uncased section near the bottom of well EE-2 by pumping… more

Wave Dynamics of Regular and Chaotic Rays

Description: In order to investigate general relationships between waves and rays in chaotic systems, I study the eigenfunctions and spectrum of a simple model, the two-dimensional Helmholtz equation in a stadium boundary, for which the rays are ergodic. Statistical measurements are performed so that the apparent randomness of the stadium modes can be quantitatively contrasted with the familiar regularities observed for the modes in a circular boundary (with integrable rays). The local spatial autocorrelati… more

Effects of sodium environment on the mechanical properties of Fe-2 1/4Cr-1Mo steel

Description: Mechanical property data on isothermally annealed, thermally aged, and sodium-exposed Fe-2 1/4Cr-1Mo steel are analyzed to evaluate the influence of the sodium environment as well as the effects of the microstructural and compositional changes that occur in the steel during long-term exposure to sodium. Correlations are developed to predict the environmental effects on tensile, creep, fatigue, and creep-fatigue properties of Fe-2 1/4Cr-1Mo steel in sodium. The results indicate that at temperatu… more

Deploymerization of coal by direct solvent attack. Semi-annual report, April 1, 1983-August 31, 1983

Description: The depolymerization of Illinois No. 6 coal by a series of solvents having different basecities (pK/sub a/) and nucleophilicities (Swain-Scott nu values) showed no dependence on either the basicity of nucleophilicity of the solvents. As expected, the conversion decreases as the temperature of the reaction is reduced, but the lower the reaction temperature, the higher the percentage of amine incorporation becomes in the products. 5 tables.

Long-term exposure of /sup 238/PuO/sub 2/ to a terrestrial environment. Volume 2

Description: Two environmental simulation chambers were used to study the behavior of a /sup 238/PuO/sub 2/ heat source deposited in a humid, temperate environment. Large fragments from an impact-tested source were deposited in the first chamber, and fines from the source were placed in the second. Plutonium released into the soil, the soil drainages, and the condensates from the dehumidifiers were monitored throughout the experiment. The concentration of plutonium released into the soil drainages increased… more

Experimental study of electron beam induced removal of H/sub 2/S from geothermal fluids

Description: The treatment of geothermal steam by electron beam irradiation is a potential alternative method of H/sub 2/S removal which can be applied upstream or downstream and has no chemical requirements. The experimental work reported here examines the effectiveness of electron beam treatment of geothermal fluids. These fluids are produced by combining the constituents in a heated cell, which contains an electron beam transparent window. Irradiation of the contents and subsequent chemical analysis allo… more

Dynamics of Tubes in Fluid with Tube-Baffle Interaction

Description: Three series of tests are performed to evaluate the effects of tube to tube-support-plate (TSP) clearance on tube dynamic characteristics and instability phenomena for tube arrays in crossflow. Test results show that, for relatively large clearances, tubes may possess TSP-inactive modes in which the tubes rattle inside some of the tube-support-plate holes, and that the natural frequencies of TSP-inactive modes are lower than those of TSP-active modes, in which the support plates provide knife-e… more

Potential low-level waste disposal limits for activation products from fusion

Description: Hanford Engineering Development Laboratory (HEDL) scientists are involved in studies considering alternative construction materials for the first wall of commercial fusion reactors. To permit a comparison of radioactivity levels, both the level of activation and an acceptable limit for the radionuclides present must be known. Generic material composition guidelines can be developed using the US Nuclear Regulatory Commission (NRC) regulations governing the near-surface disposal of low-level radi… more

Corrosion of ferrous alloys in eutectic lead-lithium environments

Description: Corrosion data have been obtained on austenitic prime candidate alloy (PCA) and Type 316 stainless steel and ferritic HT-9 and Fe-9Cr-1Mo steels in a flowing Pb-17 at. % Li environment at 727 and 700 K (454 and 427/sup 0/C). The results indicate that the dissolution rates for both austenitic and ferritic steels in Pb-17Li are an order of magnitude greater than in flowing lithium. The influence of time, temperature, and alloy composition on the corrosion behavior in Pb-17Li is similar to that in… more

Leak detection systems for uranium mill tailings impoundments with synthetic liners

Description: This study evaluated the performance of existing and alternative leak detection systems for lined uranium mill tailings ponds. Existing systems for detecting leaks at uranium mill tailings ponds investigated in this study included groundwater monitoring wells, subliner drains, and lysimeters. Three alternative systems which demonstrated the ability to locate leaks in bench-scale tests included moisture blocks, soil moisture probes, and a soil resistivity system. Several other systems in a devel… more

Recommended documentation plan for the FLAG and CHEMFLUB computer codes

Description: Reviews have been conducted on both FLAG and CHEMFLUB's documentation and computer codes. The documentation of both models is: (1) incomplete, (2) confusing, (3) not helpful to the reader, (4) filled with extraneous information and (5) lack claimed versatility in analyzing coal gasifier systems. The documentation is such that the computer coding itself must be used as a reference to complete the documentation. Once the codes are set up they are relatively easy to run. We have exercised bot… more

Search for right-handed currents in muon decay

Description: Limits are reported on right-handed currents, based on precise measurement of the e/sup +/ spetrum end point in ..mu../sup +/ decay. Highly polarized muons from the TRIUMF surface beam were stopped in metal foils within a 1.1 T spin-holding longitudinal field or a 70 G spin-precessing field. For the spin-held data, the V-A rate vanishes in the beam direction at the end point. Measurement of this sets the 90% confidence limits xi P/sub mu/delta/rho > 0.9959 and M(W/sub R/) > 380 GeV, where W/sub… more
