2 Creation of an Artificial Roll Front as a Reactive Barrier for Metal Precipitation--MBX Systems, Inc., 325 South Euclid Avenue, Suite 123, Tucson, AZ 85719-6653; (520) 620-0072 Mr. Daniel Siath, Principal Investigator Ms. Marge Karlage, Business Official DOE Grant No. DE-FG03-97ER82426 Amount: $12,422 Nearly all Department of Energy facilities have landfills, buried waste areas, or burning ...

COMMINUTION OF MINERALS BY BALL MILLING IS ENERGY INTENSIVE. ENERGY EFFICIENCY OF BALL MILLING RANGES FROM LESS THAN 1 PERCENT TO 10 PERCENT. BREAKAGE BY CRUSHING IS HIGHER IN EFFICIENCY BUT IS IMPRACTICAL FOR PRODUCTION OF A FINE MESHED PRODUCT. IT HAS BEEN ESTABLISHED IN LABORATORY TESTS THAT HIGH VELOCITY IMPACT BREAKAGE OF PARTICLES RESULTS IN COMPLETE BREAKAGE WHEREAS LOW VELOCITY IMPACTS ...

THIS WORK IS TO DEVELOP A METHOD TO IMPROVE THE ABILITY OF THE USNRC TO EVALUATE THE OPERATIONAL SAFETY SIGNIFICANCE OF OCCURANCES AT NUCLEAR POWER PLANTS. PERHAPS THE AREA OF GREATEST SAFETY SIGNIFICANCE IS HUMAN PERFORMANCE, BUT THE TECHNIQUES USED BY NRC DO NOT EVALUATE HUMAN PERFORMANCE IN ANY SYSTEMIC WAY. THE WORK IS PROPOSED TO BE PERFORMED IN THREE STAGES, AND BUILDS ON METHODS THAT HAVE B ...

TII SHALL PROCURE, DESIGN, CONSTRUCT, AND TEST A COMPACT PORTABLE SIMULATOR CAPABLE OF EMULATING NUCLEAR POWER STATION-OPERATOR (NPS-OP) INTERFACES, AND EVALUATE AND TEST VARIOUS INTERFACE DESIGNS. THE SUMULATOR WILL BE DESIGNED FOR OPERATOR TRAINING ON ADVANCED REACTORS AND WILL BE USED IN SIMULATING OPERATORS SCENARIOS AND RECORDING AND DOCUMENTING REAL-TIME INPUT FROM THE OPERATOR. THE SIMULATO ...

A THERMIONIC FUEL ELEMENT (TFE) BASED ON ADVANCED URANIUM CARBIDE (UC) SOLID SOLUTION FUEL WITH RHENIUM EMITTER CLADDING SHOULD ALLOW MUCH BETTER PERFORMANCE THAN PRESENT DESIGNS. THE FUEL FORM WOULD BE A LONG, THIN, HOLLOW "VERMICELLI" SHAPE TO ALLOW VERY COMPACT REACTORS TO BE DESIGNED, DESPITE THE HIGH NEUTRON ABSORPTION CROSS SECTION OF RHENIUM. RHENIUM IS EXPECTED TO BE COMPLETELY COMPATIBLE ...

THE DEEP CLEANING PROCESSES NOW UNDER INVESTIGATION FOR COAL MOST OFTEN INVOLVE PULVERIZING AND THE USE OF A LIQUID PROCESS MEDIUM. IF THE VERY FINE DEEP CLEANED COAL IS TO BE USED IN A DRY FORM, A SATISFACTORY DRYING TECHNOLOGY IS VITAL. PREVIOUS STUDIES HAVE INDICATED A SUBSTANTIAL PROBABILITY OF SUCCESS IF THE ULTRAHIGH LEVELS OF CENTRIFUGE GRAVITY ARE COMBINED WITH THE CENTRIFUGAL DECANTING/FI ...

THIS RESEARCH AIMS TO DEVELOP AN IMPROVED SOURCE OF MULTIPLY-CHARGED IONS FOR HEAVY-ION INERTIAL FUSION AND OTHER APPLICATIONS THAT REQUIRE VERY HIGH BRIGHTNESS. A CONVENTIONAL GAS-DISCHARGE SOURCE IS PLANNED THAT DEPENDS ON THE COMBINATION OF TWO ADDITIONAL NOVEL FEATURES. FIRST, THE INITIAL DENSE HOT PLASMA GAS GENERATED FROM A HIGH PRESSURE MICROCAPILLARY DISCHARGE IS FURTHER HEATED BY A LASER ...

THE OIL INDUSTRY GENERATES LARGE VOLUMES OF DRILLING MUD WASTES THAT CONSTITUTE AN ENVIRONMENTAL PROBLEM. CURRENT PRACTICES INVOLVE RETAINING SUCH WASTES IN PITS, OR DISPOSING THEM BY REMOVING AND TRANSPORTING THEM TO ANOTHER LOCATION FOR TREATMENT. THE TECHNOLOGY STUDIED IN THIS PROJECT IS TREATING THE MUD ON-SITE, REDUCING ITS VOLUME, AND ALLOWING THE SEPARATION OF SELECTIVE MUD COMPONENTS FOR R ...
