PHASE I OF THIS PROJECT ADDRESSES THE DEVELOPMENT OF A NOVEL LIQUID LEVEL MEASUREMENT SYSTEM CAPABLE OF ACCURATE SIMULTANEOUS DETERMINATION OF A LIQUID METAL/MOLTEN SALT AND A MOLTEN SALT/GAS INTERFACE POSITION. THE SYSTEM WILL BE APPLICABLE TO THE NEW PYROCHEMICAL NUCLEAR FUEL PROCESSING TECHNOLOGY UNDER DEVELOPMENT AT THE ARGONNE NATIONAL LABORATORY IN SUPPORT OF THE INTEGRAL FAST REACTOR CONCEP ...

IN COAL-FIRED OPEN-CYCLE MAGNETOHYDRODYNAMIC (MHD) POWERPLANTS, A KEY ISSUE IS CHLORIDE BUILDUP. A FURTHER CONSIDERATION IS THAT UNDER THE 1990 CLEAN AIR ACT AMENDMENTS, EMISSION OF HYDROCHLORIC ACID (HCI) GAS/AEROSOL FROM A CONTINUOUS SOURCE MUST BE BROUGHT BELOW 10 TONS/YEAR. POTASSIUM ADDED IN THE MHD SYSTEM UPSTREAM, TO CREATE PLASMA CONDUCTIVITY AND ACHIEVE SULFUR DIOXIDE REMOVAL, CAN ALSO CO ...

THE USE OF SILICON (SI) RADIATION DETECTORS IN PARTICLE PHYSICS RESEARCH AND OTHER APPLICATIONS IS RESTRICTED BY THE DETECTORS' SENSITIVITY TO RADIATION DAMAGE. THIS IS PARTICULARLY TRUE FOR THE NEW GENERATION OF HIGH ENERGY COLLIDERS LIKE THE SUPERCONDUCTING SUPER COLLIDER (SSC), WHERE A HIGH INTENSITY OF NEUTRONS CREATES SERIOUS BULK DAMAGE PROBLEMS. MOST OF THE RADIATION DAMAGE RESEARCH ON THES ...

THIS PROJECT INVOLVES THE DEVELOPMENT OF A MOBILE ROBOT SYSTEM THAT CAN WITHSTAND VERY HIGH LEVELS OF RADIATION AND VERY HIGH TEMPERATURES. ALTHOUGH MANY ROBOT SYSTEMS ARE PRESENTLY AVAILABLE, NONE CAN OPERATE IN THIS EXTREME ENVIRONMENT, AS WAS DRAMATICALLY EVIDENCED DURING THE RECOVERY ACTIVITIES AT THE CHERNOBYL SITE. THE PRIMARY FOCUS OF THIS PROJECT IS THE MICROPROCESSOR-BASED CONTROL SYSTEM ...

A LIGHT METAL FUELED NONEQUILIBRIUM PLASMA GENERATOR (NPG) IS BEING STUDIED. THE NPG CONCEPT BURNS HIGH ENERGY METALS (E.G., ALUMINUM), MIXING THE METAL OXIDE PRODUCTS WITH AN INERT GAS STREAM TO PRODUCE A PLASMA CAPABLE OF SUSTAINING NONEQUILIBRIUM IONIZATION IN A MAGNETOHYDRO-DYNAMIC (MHD) GENERATOR. LIGHT METAL COMBUSTION PRODUCES EXTREMELY HIGH FLAME TEMPERATURES. WHEN AN INERT GAS (AR,HE) IS ...

THIS EFFORT IS DIRECTED TOWARD THE DEVELOPMENT OF A CONTINUOUS READING OXYGEN SENSOR FOR LIQUID STEEL SERVICE. ALTHOUGH WELL KNOWN AS A CRITICAL PARAMETER IN THE ENERGY-EFFICIENT PRODUCTION OF QUALITY STEEL, OXYGEN CONTENT IS CURRENTLY MEASURED USING A DISPOSABLE ZIRCONIA SENSOR CAPABLE OF ONLY INTERMITTENT OPERATION. DESPITE THE FACT THAT FUNDAMENTALLY NOTHING HAS PRECLUDED THE USE OF SUCH A ZIRC ...

A TECHNOLOGY IS BEING EXAMINED THAT UTILIZES RESIDUE FROM ADVANCED SO2 CONTROL TECHNOLOGY COAL-COMBUSTION SYSTEMS IN THE SEPARATION OF WASTE EMULSIFIED OIL, AND THE SUBSEQUENT INTRODUCTION OF THE SOLIDIFIED MATERIAL TO A CEMENT PLANT AS AN INORGANIC RAW FEED AND LOW GRADE FUEL. PHASE I EXAMINES THE TECHNICAL, ENVIRONMENTAL, ECONOMIC, AND REGULATORY FEASIBILITY OF THE PLANNED PROCESS. SAMPLES OF AT ...

MANY U.S. MUNICIPALITIES AND COMMUNITIES ARE INTEGRATING RECYCLING PROGRAMS IN THE MANAGEMENT OF THEIR SOLID WASTE IN ORDER TO MINIMIZE LANDFILL REQUIREMENTS. INCREASINGLY, THESE RECYCLING PROGRAMS INCLUDE MATERIALS RECOVERY FACILITIES (MRF) WHERE THE MUNICIPAL SOLID WASTE (MSW), CURBSIDE COLLECTED RECYCLABLE MATERIALS, AND OTHER BAGGED WASTES ARE TRANSPORTED TO A CENTRAL LOCATION FOR THE RETRIEVA ...

FUSION SYSTEMS HAS DEVELOPED A MERCURY-FREE, HIGH COLOR RENDERING, EFFICIENT LAMP USING PROPRIETARY BUT BENIGN LAMP FILLS. THEY PROPOSE TO INVESTIGATE VARIATIONS OF THE LAMP SYSTEM PARAMETERS WITH THE DUAL GIALS OF FURTHER INCREASING SYSTEM EFFICIENCY BY 1.5 X AND TO IMPROVE LAMP STARTING DOWN TO MINUS 40C. BOTH FACTORS ARE CRITICAL TOWARD ACHIEVING COMMERCIAL SUCCESS. THE NEW LAMP IS A MICROWAVE ...
