THE MAJOR LIMITING RELIABILITY COMPONENT OF CRYOGENIC SYSTEMS HAS ALWAYS BEEN SEALS. BESIDES CONTRIBUTING TO GAS CONTAMINATION AND DEBRIS PARTICLE ACCUMULATION, SEALS HAVE PHYSICALLY FAILED; AS A RESULT, SEALS HAVE BEEN RESPONSIBLE FOR THE MAJORITY OF FAILURES OCCURRING IN CRYOGENIC LIQUIFICATION AND REFRIGERATION SYSTEMS. A POTENTIALLY VIABLE SOLUTION IS THE DEVELOPMENT OF LONG-LIFE CRYOGENIC SEA ...

IN VIEW OF THCURRENT WORLD SITUATION WITH REGARD TO THE AVAILABILITY AND PRICE INSTABILITY OF FOREIGN OIL, THERE IS AN URGENT NATIONAL NEED TO DEVELOP RENEWABLE DOMESTIC ENERGYSOURCES SUCH AS HYDROCARBON-PRODUCING CROPS (BIOMASS). HOWEVER, EFFICIENT AND COST-EFFECTIVE METHODS FOR THE SIMULTANEOUS EXTRACTION OF BOTH THE POLAR AND NON-POLAR CONSTITUTIENTS OF HYDROCARBON-PRODUCING CROPS NEED TO BE DE ...

IS PROPOSED WHICH WILL CIRCUMVENT SEVERAL OF THE LIMITATIONSOF CURRENT LINEAR POSITION-SENSITIVE DETECTORS. THE UNIQUE FEATURES OF THE PROPOSED DETECTOR ARE: MULTIPLE ANODE WIRESIN A UNIQUE SPACING ARRANGEMENT WHICH WILL DISTRIBUTE THE SPACE CHARGE OVER A WIDER AREA AND WILL LEAD TO BOTH LONGER DETECTOR LIFETIME AND HIGHER COUNT-RATE CAPABILITY; AND A NEW CONCEPT FOR A PLANAR FAN-SHAPED CATHODE WI ...

WE PROPOSE THE DEVELOPMENT OF A NEW ANALYTICAL TECHNIQUE, SPUTTER-INITIATED RESONANCE IONIZATION SPECTROSCOPY (SIRIS) FOR THE SINGLE-ATOM DETECTION OF ISOTOPES OF TECHNETIUM. THIS TECHNIQUE IS TO BE USED IN A STUDY RECENTLY PROPOSED BY G.A. COWAN AND W.C. HAXTON TO DETERMINE THE BORON-8 COMPONENT OF THE SOLAR NEUTRINO FLUX. IN SIRIS, AN ARGON ION BEAM SPUTTERS A SMALL QUANTITY OF SOLID SAMPLE INTO ...

URANIUM HEXAFLUORIDE IS THE WORKING FLUID IN THE GAS CENTRIFUGE. A NEED EXISTS FOR UF6 ASSAY DETERMINATION IN A FULLY AUTOMATED SYSTEM IN REAL-TIME. THIS PROJECT ADDRESSES THE CONCEPTUAL DEVELOPMENT OF A NEW ION TRAP TIME-OF-FLIGHT METHOD FOR MONITORING THE RELATIVE PROPORTIONS OF CLOSELY SPACED ION MASSES. IT IS DIRECTLY APPLICABLE TO THE ASSAY OF U235/U238 RATIOS IN THE UF6 GAS STREAM IN REAL-TI ...

N/A

AN EVALUATION WILL BE MADE TO DETERMINE THE FEASIBILITY OF AND METHODS FOR APPLYING INDUSTRIAL ROBOTIC COMPONENTS TO PERFORM FUSION REACTOR INSPECTION AND MAINTENANCE WORK. THE OBJECTIVE IS TO DECREASE BOTH THE RADIOLOGICAL HAZARDS TO WORKERS AND THE PLANT OUTAGE TIME REQUIRED FOR PERFORMING THE WORK. INCLUDED WILL BE A CHARACTERIZATION OF THE WORK TASKS, SELECTION OF ROBOTIC COMPONENTS AND AN EVA ...

COBALT IS A STRATEGICALLY IMPORTANT ELEMENT, AND MINIMIZING ITS USE IS A PROBLEM OF NATIONAL SIGNIFICANCE. COBALT IS USED IN CEMENTED CARBIDES, PARTICULARLY TUNGSTEN CARBIDE-COBALT, WHICH ARE IN TURN USED FOR METAL CUTTING, MINING TOOLS, WIRE DRAWING DIES AND THE LIKE. IN THIS PROPOSAL, TRA SUGGESTS A NOVEL WAY TO IMPROVE THE PROPERTIES OF WC-CO ALLOYS, AND THUS IMPROVE THE USE LIFE OF SUCH ALLOYS ...
