Brayton-cycle heat recovery-system characterization program. Subatmospheric-system test report

Description: The turbine tests and results for the Brayton cycle subatmospheric system (SAS) are summarized. A scaled model turbine was operated in the same environment as that which a full-scale SAS machine would experience from the hot effluent flue gas from a glass container furnace. The objective of the testing was to evaluate the effects of a simulated furnace flue gas stream on the turbine nozzles and blades. The following specific areas were evaluated: erosion of the turbine nozzles and blades from t… more

Ceramic phases for immobilization of /sup 129/I. [Sodalite and boracite]

Description: Materials for ultimate disposal of /sup 129/I have been studied. At present, iodide-sodalite, though not ideal, appears to be the best material for /sup 129/I immobilization from the aspects of ease of preparation, thermal stability, cost of materials, and leach resistance. Good consolidation of the material was achieved by sintering in air at 1000 to 1200/sup 0/C, but the iodine content was significantly below stoichiometric expectations. Hot aqueous media preferentially removed iodine, appare… more

Computational problems in magnetic fusion research

Description: Numerical calculations have had an important role in fusion research since its beginning, but the application of computers to plasma physics has advanced rapidly in the last few years. One reason for this is the increasing sophistication of the mathematical models of plasma behavior, and another is the increased speed and memory of the computers which made it reasonable to consider numerical simulation of fusion devices. The behavior of a plasma is simulated by a variety of numerical models. So… more

Design considerations for vehicular fuel cell power plants

Description: Fuel cells show great promise as an efficient, nonpolluting vehicular power source that can operate on nonpetroleum fuel. As with other power sources, design tradeoffs can be made that either improve vehicle performance or reduce the size and cost of the fuel cell power system. To evaluate some of these tradeoffs, a number of phosphoric acid fuel cell power plant designs have been studied to determine the performance level they would provide, both for a compact passenger vehicle and a 40-ft cit… more

Disruption scenarios for a nuclear-waste repository on the Nevada Test Site

Description: Scenarios are being constructed for the release of radioactive maerial from hypothetical repositories in different types of rock at NTS. Deductive event trees are constructed; each path through an event tree is a scenario. The complete set of NTS event trees comprises about 340 scenarios, not counting the multiple paths through the subtrees made by expanding complex events. Each of these scenarios is being analyzed for 10 different types of rocks. (DLC)

Effects of microwaves on the performance of internal-combustion engines. Final technical report, September 30, 1979-January 31, 1981

Description: Progress is reported in a research program whose goals are to expand a date base on the electrical properties of hydrocarbon-air flames, to use the amplified data base to study the interaction of microwaves with the flame both in a combustion bomb and an appropriately designed single-cylinder test engine, and to apply high power microwave energy to the bomb and test engine in order to stimulate the combustion processes. Besides the work on the microwave/flame plasma properties, work was perform… more

[Experimental and theoretical plasma physics program]. Technical progress [in FY 1981]

Description: In recent years, members of the Maryland Theory Group have made significant contributions to the national fusion theory programs and in many cases these theoretical development helped to interpret experimental results and to design new experimental programs. In the following, the authors summarize the technical progress in five major areas: (1) rf interaction with plasmas including wave propagation, rf heating, rf induced runaways and current drive; (2) spheromak -- formation, equilibrium, and … more

Geothermal well-field and power-plant investment-decision analysis

Description: Investment decisions pertaining to hydrothermal well fields and electric power plants are analyzed. Geothermal investment decision models were developed which, when coupled to a site-specific stochastic cash flow model, estimate the conditional probability of a positive decision to invest in the development of geothermal resource areas. Quantitative decision models have been developed for each major category of investor currently involved in the hydrothermal projects. These categories include: … more

Hydrogen Diffusion Behavior in Titanium-Chromium Hydrides with Laves Structures

Description: Extensive NMR measurements of the proton relaxation times have been performed on low (i.e., alpha-phase) and intermediate (i.e., alpha'-phase) hydrogen concentrations in TiCr{sub}2H{sub}x with both the hexagonal Cl4 and cubic Cl5 Laves structures. The relaxation times indicate rapid diffusion rates above 200 K for all the TiCr{sub}2H{sub}x phases; however, large differences in the diffusion activation energies are observed. This behavior is associated with the hydrogen interstitial site occupan… more

Impurity study of TMX using ultraviolet spectroscopy

Description: An extreme ultraviolet (EUV) study of the emissions from intrinsic and injected impurities in TMX is presented. Two survey spectrographs were used to determine that the major impurities present were oxygen, nitrogen, carbon, and titanium. Three absolutely-calibrated monochromators were used to measure the time histories and radial profiles of these impurity emissions in the central cell and each plug. Two of these instruments were capable of obtaining radial profiles as a function of time in a … more
