THIS PROJECT WILL INVESTIGATE AN INNOVATIVE BURNER FOR THE CONTROL OF OXIDES OF NITROGEN (NOX) FROM THE COMBUSTION OF FOSSIL FUEL, I.E., COAL AND NATURAL GAS, AND IN THE FUTURE EXTEND TO 100 PERCENT COAL TO MEET OR EXCEED THE REQUIREMENTS OF THE HIGH PERFORMANCE POWER SYSTEM (HIPPS). THE HIPPS IS A COMBINED CYCLE POWER PLANT CONSISTING OF AN INDIRECTLY FIRED BRAYTON TOPPING CYCLE AND A CONVENTION ...

A NEAR LINEAR ACCELERATOR (LINAC) STRUCTURE WILL BE IDENTIFIED AND INVESTIGATED IN PHASE I AS A POSSIBLE EXTENSION TO THE FAMILY OF STRUCTURES NOW USED FOR ACCELERATION OF CHARGED PARTICLE BEAMS. A CANDIDATE STRUCTURE HAS BEEN IDENTIFIED; OTHERS MAY BE IDENTIFIED IN THE COURSE OF THE INVESTIGATION. THE IDENTIFIED STRUCTURE UTILIZES A FOUR-FINGERED GEOMETRY TO PRODUCE RADIO FREQUENCY (RF) ELECTRI ...

THERE IS A RENEWED INTEREST IN FUEL CELLS AS PRIMARY POWER SOURCES FOR ELECTRIC VEHICLES. THE ACIDIC PROTON EXCHANGE MEMBRANE FUEL CELL OPERATES AT A MAXIMUM TEMPERATURE OF 95 DEGREES CENTIGRADE AND, AT PRESENT, RELIES ON THE USE OF PLATINUM-BASED ELECTROCATALYSTS. FOR ACID FUEL CELLS OPERATING AT TEMPERATURES BELOW 130 DEGREES CENTIGRADE, HYDROGEN IS THE MOST ACTIVE COMMON FUEL THAT CAN BE USED ...

THE NATION DESIRES TO EXPAND THE USE OF CLEAN BURNING, COMPETITIVELY PRICED NATURAL GAS. THE INCREASED DEMAND FOR NATURAL GAS HAS PROMPTED NEW DRILLING IN ESTABLISHED GAS FIELDS. THE PROPER PLACEMENT OF THE NEW WELLS IS DEPENDENT ON THE GAS FORMATION PROPERTIES BETWEEN THE EXISTING WELLS. ONE OF THE PROPERTIES IS THE THICKNESS OF THE GAS BEARING ZONE. IT IS GENERALLY ACCEPTED THAT THE FORMATIO ...

THIS PROJECT WILL ASSESS THE FEASIBILITY OF USING MULTIMEDIA-AUGMENTED SOFWEARE TUTORIALS TO SUPPORT TEACHING THE PRINCIPLES OF EXPERIMENTAL NUCLEAR PHYSICS. THE DETECTOR SYSTEM FOR THE PHOTON TAGGING FACILITY AT THE CONTINUOUS ELECTRON BEAM ACCELERATOR FACILITY (CEBAF) IN NEWPORT NEWS, VIRGINIA IS NOW UNDER CONSTRUCTION AT THE NUCLEAR DETECTOR LABORATORY OF THE CENTER FOR NUCLEAR STUDIES OF THE ...

GAS TRANSMISSION PIPELINES REQUIRE NATURAL GAS DELIVERED TO THEM TO MEET A HYDROCARBON (HC) DEWPOINT SPECIFICATION IN ORDER THAT THE HC LIQUIDS ARE NOT DROPPED OUT IN THE LINE DURING TRANSMISSION. SIMILAR SPECIFICATIONS ARE IMPOSED BY PLANT OPERATORS ON THE FUEL GAS THAT IS CONSUMED BY THEIR MACHINERY. A MARKET EXISTS FOR AN ECONOMICAL AMMONIA (NH3) ABSORPTION UNIT TO REPLACE COMPRESSION UNITS U ...

TRADITIONALLY, SUPE2RCONDUCTING CAVITIES FOR LARGE ELECTRON POSITION COLLIDERS ARE FABRICATED FROM HIGH PURITY NIOBIUM (NB) SHEETS USING LATHE SPINNING AND WELDING. THESE CAVITIES SUFFER FROM THE PROBLEM OF THERMOMAGNETIC BREAKDOWN RESULTING FROM THE RELATIVELY POOR THERMAL CONDUCTIVITY OF NB AT LIQUID HELIUM TEMPERATURES. A MORE ELEGANT AND LOW COST SOLUTION TO THE BREAKDOWN PROBLEMS IS THE USE ...

DOE IS ACTIVELY PURSUING INNOVATIVE TECHNIQUES FOR DETECTING HUMAN PRESENCE IN ENCLOSED AREAS. THIS IS NECESSARY FOR SUCH CIRCUMSTANCES AS PERSONNEL SAFETY IN VAULTS CONTAINING SPECIAL NUCLEAR MATERIALS, INTRUSION DETECTION IN SENSITIVE FACILITIES, AND EVEN AUTOMATING VAHICLE INSPECTION. THE KEY OBJECTIVE IS TO ELIMINATE FALSE ALARMS WHILE PROVIDING POSITIVE DETERMINATION WHEN A HUMAN IS PRESENT ...
