Conceptual model for regional radionuclide transport from a basalt repository site. Final draft, technical memorandum

Description: This technical memorandum was prepared to: (1) describe a typical basalt radionuclide repository site, (2) describe geologic and hydrologic processes associated with regional radionuclide transport in basalts, (3) define the parameters required to model regional radionuclide transport from a basalt repository site, and (4) develop a ''conceptual model'' of radionuclide transport from a basalt repository site. In a general hydrological sense, basalts may be described as layered sequences of aqui… more

Buildup studies for MFTF-B

Description: A one-dimensional radial transport code which was developed to study radial transport in tandem mirror machines has been used to perform buildup studies for the central-cell plasma of the proposed MFTF-B experiment. The effects of the cold, unpumped, neutral gas (which accompanies the hot, neutral-beam injection in the central cell) upon the central-cell plasma have been studied for the low-epsilon (epsilon Identical with (..cap omega../sub pi//..cap omega../sub ci/)2) mode and for the two-comp… more

Revegetation of Alaskan coal mine spoils. Progress report

Description: Activities initiated after the start of the revegetation project on Alaskan coal mine spoils on September 1, 1979 have consisted mainly of some fall plantings (dormant seedings) and soil and coal spoil samplings and analyses. Because of the late summer start for the project, only a limited amount of field work could be initiated in plant material studies. This consisted of a fall planting at the Usibelli mine site at Healy in interior Alaska. The planting was intended to test the efficacy of se… more

Thermodynamic study of the MWG system/components and measurement of the oxygen partial pressure in the heat source capsule

Description: A thermodynamic study of the Milliwatt Generator heat source capsule was performed to determine the effects of the oxide fuel on container materials at elevated temperatures in order to evaluate the factors affecting embrittlement of T-111 alloy. The study indicates that relatively slow oxidation of the T-111 of the capsule occurs during pretreatment. Yttrium added to the /sup 238/PuO/sub 2/ fuel charge is functioning in its designed role as an oxygen getter and is stabilizing at an O/Pu ratio … more

Simple spherical ablative-implosion model

Description: A simple model of the ablative implosion of a high-aspect-ratio (shell radius to shell thickness ratio) spherical shell is described. The model is similar in spirit to Rosenbluth's snowplow model. The scaling of the implosion time was determined in terms of the ablation pressure and the shell parameters such as diameter, wall thickness, and shell density, and compared these to complete hydrodynamic code calculations. The energy transfer efficiency from ablation pressure to shell implosion kinet… more

Feasibility analysis of geothermal district heating for Lakeview, Oregon

Description: An analysis of the geothermal resource at Lakeview, Oregon, indicates that a substantial resource exists in the area capable of supporting extensive residential, commercial and industrial heat loads. Good resource productivity is expected with water temperatures of 200{degrees}F at depths of 600 to 3000 feet in the immediate vicinity of the town. Preliminary district heating system designs were developed for a Base Case serving 1170 homes, 119 commercial and municipal buildings, and a new alcoh… more

MITRE progress report No. 2

Description: This progress report documents the major accomplishments on the two remaining SEAS tasks for the period of July 10 to August 8, 1980. The tasks are SEAS scenario runs, and SEAS management, documentation, maintenance and support. The scenario run work in this month period consisted of the completion of the TASE 6 scenario on the reference system, development of an ARMS baseline scenario and a run of the NEP2 scenario. The SEAS management, documentation, maintenance and support task continued at … more

Emerging material systems for solar-cell applications. Technical progress report No. 3, 17 October 1979-16 January 1980

Description: Progress is reported on a program to develop an InP/CdS polycrystalline thin film solar cell. The plasma deposition system was completed and a number of depositions of InP were made with the indium transported into the reaction zone via the vapor phase transport of indium chloride. Amorphous film of InP were obtained when the substrate was at room temperature. Substrate temperatures above approximately 200/sup 0/C resulted in polycrystalline films. Junctions were formed in n-type InP by diffusi… more

Environmental assessment for the Consumer Products Efficiency Standards program

Description: The Energy Policy and Conservation Act of 1975 as amended by the National Energy Conservation Policy Act of 1978, requires the DOE to prescribe energy efficiency standards for thirteen consumer products. The Consumer Products Efficiency Standards (CPES) program covers the following products: refrigerators and refrigerator-freezers; freezers;clothes dryers;water heaters; room air conditioners; home heating equipment (not including furnaces); kitchen ranges and ovens; central air conditioners (co… more

LOFT LTSF Thermocouple Thermal Analysis to Detemrine Transient Temperature Response

Description: A two-dimensional finite element model of the LOFT LTSF thermocouple assembly was developed to study the thermal response of the thermocouples to the expected temperature transient in the L3-4, 5 and 6 experiments. Subjecting the thermocouple model to a 10 F fluid temperature step change resulted in a .10 second delay before 95% of the step change was observed in the thermocouple temperature response. A thermal analysis was performed on the Loft Test Support Facility (LTSF) small-break thermoco… more

Simple Lattice for the Precoo1er/Accumu1ator Scheme

Description: The Precoo1er/Accumu1ator scheme uses RF stacking to collect antiprotons produced by a mu1tipu1se proton extraction from the Main Ring. The stacking requires X{sub p} {approx} 2.5 m at the injection septum; therefore, a simple expansion of the present precoo1er lattice from {bar R} = 75 m to {bar R} = 101 m is not practical. It is possible that an appropriate high-X{sub p} insertion could be designed so that the increase in {gamma}{sub T} from the larger ring would cancel the decrease caused by… more

Chapter II.C Transport of Radionuclides through Soil and Ground Water

Description: The purpose of this report is to provide a clearer perspective of the impact of radionuclides in soil and groundwater, particularly for those not well-versed in soil science, hydrology, and geology. Through nuclear waste disposal or accidents, radionuclides come in contact with soil and groundwater. Man is exposed to radiation as a result of movement (or transport) of the radionuclides into his environment. Water is the principal carrier that induces transport, but chemical characteristics of s… more

Silicon materials task of the low cost solar array project (Phase III). Effects of impurities and processing on silicon solar cells. Phase III summary and seventeenth quarterly report, Volume 2: analysis of impurity behavior

Description: The object of this phase of the program has been to investigate the effects of various processes, metal contaminants and contaminant-process interactions on the properties of silicon and on the performance of terrestrial silicon solar cells. The study encompassed topics including thermochemical (gettering) treatments, base doping concentration, base doping type (n vs. p), grain boundary-impurity interaction, non-uniformity of impurity distribution, long term effects of impurities, as well as sy… more

Foreign Ownership of Property in the United States: Federal and State Restrictions

Description: This report examines various legal issues raised by Federal and State laws restricting foreign ownership in U. S. property. The report examines the constitutional barriers to Federal and State laws restricting such ownership, and the possible constitutional predicates for Federal legislation regulating foreign ownership of property in the united States. The impact of treaties to which the United States is a party on both Federal and State restrictions on the rights of foreign persons to own U.S… more
