THE COST OF OFF-GAS TREATMENT DURING REMEDIATION OF HAZARDOUS WASTE SITES CAN TYPICALLY INCREASE THE COST BY 50% OR MORE. THIS RESEARCH IS TARGETED TOWARDS DEVELOPING A SIMPLE COST EFFECTIVE TECHNOLOGY TO DESTROY CHLORINATED ORGANIC SOLVENTS IN THE VAPOR PHASE. THE PROCESS USES A DRY CHEMICAL AT A SLIGHTLY ELEVATED TEMPERATURE. THE RESEARCH INVOLVES TESTING OF A VARIETY OF RELATED DRY CHEMICALS IN ...

THE THREE-WAY CATALYTIC CONVERTER IS THE MOST IMPORTANT DEVICE MAKING TODAY'S AUTOMOBILES COMPLY WITH EXISTING EMISSION LAWS. THE FIRST TWO OR THREE MILES IN A TYPICAL 22-MINUTE, 12-MILE COMUTE IN TODAY'S VEHICLES RESULT IN THE EMISSION OF HALF OF THE TOTAL NON-METHANE HYDROCARBONS, WHICH RESULT IN THE PRODUCTION OF URBAN SMOG, AS WELL AS HALF OF THE TOXIC CO EMISSIONS. THIS OCCURS BECAUSE THE CAT ...

DIVERSION OF PLASTICS FROM LANDFILL TO RECYCLING CAN POTENTIALLY SAVE THE ENERGY EQUIVALENT OF 60 MILLION BARRELS OF OIL ANNUALLY AND REDUCE LANDFILL VOLUME REQUIRMENTS BY UP TO 20%. THE U.S. ENVIRONMENTAL PROTECTION AGENCY HAS RECOMMENDED THAT SOURCE REDUCTION, RECYCLING, VOLUME REDUCTION, AND LANDFILLING BE APPLIED, IN THAT ORDER, IN THE TREATMENT OF MUNICIPAL SOLID WASTE (MSW). RECYCLING HAS RE ...

EACH YEAR, AMERICANS DISPOSE OF AN ESTIMATED 29 BILLION POUNDS OF PLASTICS WHICH CONSUME UP TO 20% OF OUR NATION'S ANNUAL LANDFILL CAPACITY. RECENT ENVIRONMENTAL AND POLITICAL PRESSURES HAVE LED TO RAPID ESTABLISHMENT OF PLASTICS RECYCLING FACILITIES. LIMITED MARKETS FOR LOW QUALITY RECYCLED RESINS REQUIRE RECLAIMERS TO PRODUCE THE HIGHEST QUALITY RECYCLED RESINS IN ORDER TO COMPETE WITH VIRGIN RE ...

THE LAST THREE YEARS HAVE SEEN A DRAMATIC INCREASE IN THE NUMBER OF COMPANIES PROCESSING POST-CONSUMER PLASTICS FROM PRODUCTS SUCH AS SOFT DRINK CONTAINERS, DETERGENT BOTTLES, MILK JUGS AND WATER BOTTLES. WHILE THIS HAS TO SOME EXTENT DIVERTED THESE MATERIALS FROM LANDFILLS, IT HAS CAUSED AN ECONOMIC ANOMALY. THE HIGH COSTS OF MANUALLY SORTING THE PLASTICS SO THEY CAN BE REPROCESSED MAKES THEM UNA ...

THE TECHNICAL OBJECTIVES OF THIS PROPOSAL ARE ORIENTED TOWARD THE DEVELOPMENT OF SOIL SURFACTANT FLUSHING AND WASHING AS A LOW-COST, LOW-IMPACT, LOW-RISK, EFFECTIVE TECHNIQUE FOR THE REMOVAL AND ULTIMATE DESTRUCTION OF THE ORGANIC CONTAMINANTS IN SOIL. THESE OBJECTIVES ARE: DEMONSTRATION OF THE EFFECTIVENESS OF AN IONIC SURFACTANT SOLUTION AT CONCENTRATIONS ABOVE THE CRITICAL MICELLE CONCENTRATION ...

INSPECTION OF PAINTED OR COATED CARBON STEEL SURFACES OFTEN INVOLVES THE REMOVAL OF THE COATING PRIOR TO INSPECTION, ESPECIALLY WHEN THE USE OF MAGNETIC PARTICLE TESTING (MT) IS REQUIRED. IN THE CASE OF EXAMINATION OF CONTAINMENT VESSEL WALLS IN NUCLEAR POWER PLANTS, THE REMOVAL IS TIME CONSUMING, RESULTING IN INCREASED RADIATION EXPOSURE TO WORKERS. IN ADDITION, THE REMOVAL MUST BE DONE WITHOUT C ...

THIS PROPOSAL IS PREPARED IN DIRECT RESPONSE TO THE NRC'S SOLICITATION FOR AN IMPROVED DEVICE TO MEASURE AIR MOVEMENT FOR PERSONNEL RADIATION PROTECTION AND HEALTH PHYSICS APPLICATIONS IN NUCLEAR FACILITIES. THE PURPOSE OF THE NEW DEVICE IS TO PROPERLY LOCATE AIR SAMPLERS SO THAT THE AIR SAMPLED IS REPRESENTATIVE OF THE AIR INHALED BY WORKERS. ALTHOUGH AIR FLOW RATE SENSORS SUCH AS ANEMOMETERS ARE ...

AT MULTI-UNIT NUCLEAR GENRATING STATIONS, CONTROL ROOM OPERATORS ARE GENERALLY LICENSED TO OPERATE ALL SIMILAR UNITS. SIMULATOR TRAINING CONDUCTED AT THE LICENSEE TRAINING FACILITY OCCURS ON ONE SIMULATOR WHICH MAY NOT EXACTLY MIMIC ANY UNIT. INADEQUATE TRAINING ON UNIT-TO-UNIT AND UNIT-TO-SIMULATOR DIFFERENCES, IN CONJUNCTION WITH LIMITED PER-PERSON SIMULATOR TRAINING HOURS, CAN RESULT IN INCREAS ...
