This paper describes the ALICE-II analysis of and comparison with complex vessel experiments. Tests SM-2 through SM-5 were performed by SRI International in 1978 in studying the structural response of 1/20 scale models of the Clinch River Breeder Reactor to a simulated hypothetical core-disruptive accident. These experiments provided quality data for validating treatments of the nonlinear fluid-structure interactions and many complex excursion phenomena, such as flow through perforated structures, large material distortions, multi-dimensional sliding interfaces, flow around sharp corners, and highly contorted fluid boundaries. Correlations of the predicted pressures with the test results of all gauges are made. Wave characteristics and arrival times are also compared. Results show that the ALICE-II code predicts the pressure profile well. Despite the complexity, the code gave good results for the SM-5 test.

This topical report presents the results of work to-date on the analysis and simulation of flow and pressure data from the testing of the L.R. Sweezy No. 1 well. Analysis of drawdown data indicates a formation permeability of around 126 md, and a flow-rate dependent skin. The conventional analysis techniques were, however, found to be inadequate for analyzing the buildup data. The formation properties inferred from the drawdown were used together with the CHARGR simulator to simulate the production history of the Sweezy well. The calculated drawdown response displays excellent agreement with the measured data; such agreement was, however, not obtained for the buildup phase of the tests. Parametric calculations designed to investigate the anomalous buildup response suggest that this behavior may be the result of stress-induced hysteresis in formation properties, shale recharge, and long-term formation creep. A research program to further characterize the observed pressure response is outlined.

Environmental monitoring results continue to demonstrate that environmental radiological impact due to SLAC operation is not easily distinguishable from natural environmental sources. During 1983, the maximum approximated neutron dose near the site boundary was 5 mrem. There have been no measurable increases in radioactivity in ground water attributable to SLAC operations since operation began in 1966. We have never found any evidence of radioactivity in ground water in excess of natural background radioactivity from uranium and thorium decay chains and potassium-40. Airborne radioactivity released from SLAC continues to make only a negligible environmental impact, and results in a site-boundary annual dose of less than 0.3 mrem; this represents less than 0.3% of the annual dose from the natural radiation environment, and about 0.06% of the technical standard. 8 references, 5 figures, 4 tables.

A strain-gauged proving-ring transducer was designed and deployed to measure small diametral displacements in 0.61-m diameter boreholes in rock. The rock surrounding the boreholes was previously heated by storage of spent nuclear fuel assemblies and measurements during post-retrieval cooling of the rock were made. To accomplish this, a transducer was designed to measure displacements in the range of 10 to 100 {mu}m, to function in a time-varying temperature regime of 30{sup 0} to 60{sup 0}C at a relative humidity of 100%, to be of low stiffness, and to be easily and quickly installed. 7 references, 6 figures, 1 table.

Pacific Northwest Laboratory (PNL), under contract to the US Department of Energy (DOE) Uranium Mill Tailings Remedial Action Project (UMTRAP) office, has developed an asphalt emulsion cover system to reduce the release of radon from uranium mill tailings. The system has been field tested at Grand Junction, Colorado. Results from laboratory and field tests indicate that this system is effective in reducing radon release to near-background levels (<2.5 pCi m/sup -2/s/sup -1/) and has the properties required for long-term effectiveness and stability. Engineering specifications have been developed, and analysis indicates that asphalt emulsion covers are cost-competitive with other cover systems. This report summarizes the technology for asphalt emulsion radon barrier systems. 59 references, 45 figures, 36 tables.

The results of an independent assessment of core disruptive accident energetics for the Clinch River Breeder Reactor are presented in this document. This assessment was performed for the Nuclear Regulatory Commission under the direction of the CRBR Program Office within the Office of Nuclear Reactor Regulation. It considered in detail the accident behavior for three accident initiators that are representative of three different classes of events; unprotected loss of flow, unprotected reactivity insertion, and protected loss of heat sink. The primary system's energetics accommodation capability was realistically, yet conservatively, determined in terms of core events. This accommodation capability was found to be equivalent to an isentropic work potential for expansion to one atmosphere of 2550 MJ or a ramp rate of about 200 $/s applied to a classical two-phase disassembly.

It has been demonstrated that an intense beam with the space charge defocussing force as large as the average focussing forces of the channel can be transported over many lattice periods without losing either the current or the optical quality. This conclusion, which is consistent with the PIC code results, has an important implication in designing a linear induction accelerator driver for inertial confinement fusion.

This report presents progress for the second quarter of performance on Contract Number DE-AC22-83PC63032. The effort includes Tasks 6 through 13 of a continuing program to demonstrate the TRW Gravimelt coal cleaning technology. The technical effort this quarter has concentrated on defining an operable flow scheme, conducting the required supporting laboratory tests and establishing the performance of the bench scale centrifuge. Key to directing the development and scale-up activity, was the definition of the process flow scheme. Based on laboratory studies of the reaction and the washing/separation steps, it was concluded that a counter-flow reactor system was needed to make the separation of mineral-rich caustic from the processed coal. The absence of mineral matter should also improve the filtration of the processed coal. Each of the steps have been reviewed to determine where industry experience with similar operations may be able to reduce development effort or increase confidence. Laboratory testing has established the general effect of impure caustic on the reaction rate and extent of ash and sulfur removal. The bench-scale centrifuge was used to concentrate processed coal from caustic slurries in the range of 2 to 5% coal in 5 to 15% aqueous caustic. Centrifuge cakes generally were thick …

The various formulae for calculating calorific values for coals from ultimate analyses depend essentially on a propositon due to Dulong, that the heat of combustion of an organic compound is nearly equal to the heats of combustion of the elements in it, multiplied by their percentage content in the compound in question. This proposition assumes that the enthalpy of decomposition is negligible compared with the heat of combustion. The various published formulae, such as that due to Mott and Spooner, include empirical adjustments to allow for the fact that the enthalpy of formation or decomposition of no organic compound is zero (except rarely by chance). A new equation is proposed, which excludes empirical correction terms but includes a term explicitly related to the enthalpy of decomposition. As expected from the behavior of known compounds, this enthalpy varies with rank, but it also varies at the same level of rank with the geological history of the sample: rank is not the only source of variance in coal properties. The new equation is at least as effective in predicting calorific values for a set of 992 coals as equivalent equations derived for 6 subsets of the coals. On the whole, the distributions …

A program was started in FY 1982 to evaluate the compatibility of WESF-produced CsCl with 316L stainless steel under the thermal conditions that would be encountered in a geologic repository. The major part of the program involves compatibility testing of six standard WESF CsCl capsules at a maximum CsCl/metal interface temperature of 450/sup 0/C. The capsules are allowed to self heat to the test temperature in insulated containers and then held at temperature for 2200 to 32,000 h. After thermal aging, the capsules are destructively examined to determine the extent of the metal attack by the CsCl. This report describes the test procedure and summarizes the results obtained during the second year of the program. Metallographic examination was completed of the two zero-time capsules. The photomicrographs obtained of the metal samples indicate the maximum metal attack resulting from the capsule-filling operation was about 25 ..mu..m. Metallographic examination of the WESF CsCl capsules held at temperature for 2208 and 4392 h was completed. Both capsules exhibited substantial attack by the CsCl. Maximum attack observed in the 2208-hour capsule was estimated to be about 60 ..mu..m, while maximum attack in the 4392-h capsule was estimated at 110 ..mu..m. The data indicate the …

Magnetic structures in modern storage rings provide an assured route to fundamentally new opportunities for extending coherent radiation experiments to the vacuum ultraviolet and soft x-ray spectral regions. Coherent power levels of order 10 milliwatts are anticipated, in a fully spatially coherent beam, with a longitudinal coherence length of order 1 ..mu..m. In addition to broad tuneability and polarization control, the radiation would occur in 20 psec pulses, at 500 MHz repetition rate.

This report describes an experimental program and techniques for studying the internal aerodynamics of pulverized coal combustors of the type used in magnetohydrodynamic test trains at The University of Tennessee Space Institute. The combustors are modeled with small scale, cold flow models that permit both flow visualization and velocity field surveys to be performed. Water was selected as the working fluid so that the model flow fields had the same Reynolds number as the actual reactive combustors, and also to facilitate flow visualization. The systems used for flow visualization and velocity field surveying are described in detail. The velocity field survey equipment is based on a vector-velocity, laser doppler velocimeter coupled to a controllable field scanning device and a microprocessor for on-line data reduction. Results are presented that were obtained from a laser velocimeter study of recirculating flows in a combustor model. The results show that, even for exceedingly simple geometrical arrangements of oxidant injector configurations, complex three dimensional highly turbulent flow fields exist in the combustor. A brief discussion of the impact of the results on fuel injector positioning is presented.

Part II includes a history of the commercial operation of the Maxey Flats Nuclear Waste Disposal Site in Fleming County, Kentucky. The reasons for closure of the facility by the Human Resources Cabinet, the licensing agency, are identified. The site stabilization program managed by the Natural Resources and Environmental Protection Cabinet is described in Chapter VI. Future activities to be conducted at the Maxey Flats Disposal Site will include site stabilization activities, routine operations and maintenance, and environmental monitoring programs as described in Chapter VII.

The present work represented a laboratory study to assess optical access ports (OAP) effectiveness of three different designs. The flow conditions were controlled and OAP geometries were simple. These experiments are important for understanding the basic mechanics of OAP operation. For applications to coal conversion process streams, the design features become increasingly complex and the OAP must be operational at a specific location. Laboratory experiments addressed the rate of contamination of three OAP designs (one recessed window and two minimal-offset window designs). The rate of window contamination as measured by the relative light intensity decreased as the purge flow was increased for the recessed window design. For purge flows representing about 20 percent of the stream flow, no contamination of the windows was observed with this design. The minimal-offset, single-jet OAP did not effectively diminish window contamination. The window contamination increased as the purge flow rate was increased from zero purge. Of the three designs tested, the recessed window, porous metal insert design appears to be best suited for long-term applications (greater than 30 hours exposure time). The particulate deposition was uniform over the window surface for this design. The minimal-offset, single-jet OAP was effective for cleaning a small localized …
