Low cost solar collector of a packed bed design

Description: Two solar collectors using a pebble bed design were constructed and tested using air as the heat exchange media. One collector had pebbles of metallurgical grade coke, and the other had a frothy volcanic material called scoria. The highly irregular surface of such vesicular material should increase the path distance for the air and the surface exposed cavities should give some honeycomb effect. Both should yield greater efficiency. Actual testing shows the efficiencies to be comparable with oth… more

LOFT shield tank steady state temperatures with addition of gamma and neutron shielding

Description: The effect of introducing a neutron and gamma shield into the annulus between the reactor vessel and the shield tank is analyzed. This addition has been proposed in order to intercept neutron streaming up the annulus during nuclear operations. Its installation will require removal of approximately 20-/sup 1///sub 2/ inches of stainless steel foil insulation at the top of the annulus. The resulting conduction path is believed to result in increased water temperatures within the shield tank, poss… more

Economic model of pipeline transportation systems

Description: The objective of the work reported here was to develop a model which could be used to assess the economic effects of energy-conservative technological innovations upon the pipeline industry. The model is a dynamic simulator which accepts inputs of two classes: the physical description (design parameters, fluid properties, and financial structures) of the system to be studied, and the postulated market (throughput and price) projection. The model consists of time-independent submodels: the fluid… more

High pressure relief valve quenching. Supplement 1

Description: In response to additional needs developed during a review of the LOFT Technical Specifications, two more pressure reduction and decontamination sump volume vs. initial temperature data points were calculated in order to adequately quench steam generator relief blowdown. The two additional points chosen were for 10,000 gallons (based on ECC requirements) and for 120/sup 0/F (NPSH limit maximum temperature). The results are that for 10,000 gallons in the sump the maximum initial temperature is 11… more

Ion exchange flowsheet for recovery of cesium from purex sludge supernatant at B Plant

Description: Purex Sludge Supernatant (PSS) contains significant amounts of /sup 137/Cs left after removal of strontium from fission product bearing Purex wastes. To remove cesium from PSS, an Ion Exchange Recovery system has been set up in Cells 17-21 at B Plant. The cesium that is recovered is stored within B Plant for eventual purification through the Cesium Purification process in Cell 38 and eventual encapsulation and storage in a powdered form at the Waste Encapsulation Storage Facility. Cesium deplet… more

Shock initiation of PBXN-5 and PBX-9604

Description: The PBXN-5 and PBX-9604 shock Hugoniots, longitudinal and shear sound velocities, and response to long and short duration shocks have been determined. At a density of 1.66 Mg/m/sup 3/, PBXN-5 requires a minimum copper flyer kinetic energy of 382 kJ/m/sup 2/ for initiation at a flyer velocity of 0.8 km/s. At a density of 1.49 Mg/m/sup 3/, PBX-9604 requires a minimum flyer energy of 201 kJ/m/sup 2/ for initiation at the same velocity.

Evaluation of selected chemical processes for production of low-cost silicon (Phase II). Silicon Material Task, Low-Cost Silicon Solar Array Project. Fifth--sixth quarterly progress report, October 1, 1976--March 31, 1977. [Zinc reduction of silicon tetrachloride in fluidized bed]

Description: The results of experimental work and economic analyses carried out during the first 12 months of this contract (Phase I) have led to Battelle's concentration on development of the zinc reduction of silicon tetrachloride on seed particles in a fluidized bed. A second year program (Phase II) has been initiated which consists of the design of a 25 MT/year experimental facility and supporting experiment effort. During this quarter, the effort in the plant design portion of the program has been devo… more

Progress report for the Division of Safeguards and Security: July--December 1976. [Development of nondestructive assay measurements, systems development, and applications]

Description: In the work on prediction of calorimeter equilibrium, a newly derived single-exponential prediction equation has been shown to yield results equal to those from previously reported work, but allows for more versatility in the instrumentation selection. A single-precision rather than a double-precision calculator is all that is required to predict reliable equilibrium values using this new equation. A double-exponential prediction equation has also been derived and tested using simulated data. E… more

Overview of the geothermal energy development program at the Lawrence Livermore Laboratory

Description: The program consists generally of development of advanced conversion systems, with strong emphasis on a systems approach to find solutions of the problems of scale formation, corrosion/erosion of materials, spent brine disposal and solids handling, and development of reliable, efficient energy conversion systems with strong emphasis on development of the total flow concept. The status of the various parts of this program is reviewed briefly. (MHR)

Reliability estimation for multiunit nuclear and fossil-fired industrial energy systems

Description: As petroleum-based fuels grow increasingly scarce and costly, nuclear energy may become an important alternative source of industrial energy. Initial applications would most likely include a mix of fossil-fired and nuclear sources of process energy. A means for determining the overall reliability of these mixed systems is a fundamental aspect of demonstrating their feasibility to potential industrial users. Reliability data from nuclear and fossil-fired plants are presented, and several methods… more

Geological exploration of potential underground coal gasification sites in the Powder River Basin of Wyoming and Montana

Description: Information obtained from exploratory drilling of potential coal-gasification sites in the Powder River Basin of Wyoming and Montana is summarized. The objectives were to obtain stratigraphic descriptions of the coal-bearing strata from cuttings and geophysical logs, determine the hydrologic characteristics of the coal and associated strata, and see if there were drilling and logging problems associated with deep, thick coal seams. It was decided to do preliminary hydrologic and gasification ex… more

Simulation of boiling pools with internal heat sources by gas injection. [LMFBR core meltdown]

Description: Heat transfer from the sides and bottom of an open non-boiling liquid pool with spatially uniform internal gas injection was studied experimentally, both in transient and in steady state. The results were compared with experimental data for a boiling pool without permanent gas injection undertaken at Argonne National Laboratory. Typical Nusselt number versus Reynolds number plots showed that heat transfer rates were much higher in the gassy pool due to more efficient circulation. A correction w… more
