A MAJOR BARRIER TO EXTENDING THE BURNUP OF LIGHT WATER REACTOR FUEL IS THE BUILDUP OF FISSION PRODUCTS IN THE REACTOR COOLANT, WHICH MAY APPROACH PLANT CHEMISTRY OR EFFLUENTS TECHNICAL SPECIFICATIONS NEAR THE END OF CORE LIFE. IT IS PROPOSED TO USE CURRENTLY INSTALLED AUTOMATED ISOTOPIC REACTOR COOLANT ASSAY SYSTEMS AT UP TO FOUR OPERATING NUCLEAR POWER REACTORS TO EXPLORE THE RELATIONSHIPBETWEEN ...

BECAUSE OF THE EXPENSE AND COMPLEXITY OF MANNED FLIGHTS IT IS DESIRABLE TO PERFORM MANY OF THE NASA SPACE MISSIONS BY TELEOPERATOR CONTROL OF SPACE-BASED ROBOTIC SYSTEMS. THE REMOTE ORBITAL SERVICING SYSTEM (ROSS) IS BEING DEVELOPED TO ENABLE AN UNMANNED SPACE VEHICLE TO PERFORM MAINTENANCE AND REPAIR DUTIES. UNLIKE INDUSTRIAL ROBOTS, THE ROBOTIC SERVICER KIT PORTION OF ROSS WILL NEED TO OPERATE I ...

WORK IS PROPOSE TO ASSESS THE FEASIBILTY OF SODIUM\SULFUR-SELENIUM BATTERIES FOR ELECTRICALLY POWERED WEAPONS SYSTEMS ABOARD AIR BREATHING AIRCRAFT AND FOR ENERGY STORAGE ABOARD ORBITAL FLIGHT VEHICLES. SEVERAL POTENTIAL ADANTAGES OF THE SODIUM\ SULFUR-SELENIUM BATTERY OVER THE SODIUM-SULFUR BATTERY ARE POINTED OUT, INCLUDING HIGHER POWER AND ENERGY DENSITIES AND LONGER LIFETIMES. BASED ON SOME PR ...

THE DOD SOFTWARE INITIATIVE CLEARLY IDENTIFIED THE CHALLENGES FOR FUTURE SYSTEMS. THEY WILL HAVE TO BE LARGER AND MORE COMPLEX, DEVELOPED AND DELIVERED MORE RAPIDLY, AND MAINTAINED OVER LONGER PERIODS. TRADITIONAL PROGRAMMING TECHNIQUES, HOWEVER, APPEAR TO HAVE REACHED THEIR LIMITS, MAKING MUCH LARGER SOFTWARE SYSTEMS VIRTUALLY IMPOSSIBLE TO BUILD AND MAINTAIN. AN ALTERNATIVE APPROACH, CALLED FUNC ...

DESIGN OF EFFECTIVE MAN-MACHINE INTERFACES (MMI) IS CRITICAL TO THE OPERATIONAL EFECTIVENESS OF INTERACTIVE COMPUTER SYSTEMS. UNFORTUNATELY, MMI DESIGN FLAWS USUALLY ARE NOT UNCOVERED UNTIL LATE IN THE IMPLEMENTATION PHASE WHEN THEIR CORRECTION IS VERY EXPENSIVE OR IMPOSSIBLE. RAPID PROTOTYPING TOOLS HAVE BEEN USE TO ALLEVIATE THESE PROBLEMS BY ALLOWING MMI DESIGNS TO BECOME VISIBLE AND MODIFIABLE ...

HIGHLY ANISOTROPIC ALIGNED UNIAXIAL POLYCRSTALLIVE HEXAGONAL FERRITE COMPOUNDS POSSES BUILT-IN EFFECTIVE MAGNETIC FIELDS. THESE MATERIALS POSSESS ATTRACTIVE MICROWAVE AND MAGNETIC PROPERTIES OF POTENTIAL IMPORTANCE TO ACHIEVE IMPROVED PERFORMANCE IN AND INNOVATIVE STRUCTURES FOR NONRECIPROCAL CIRCUIT FUNCTIONS AT NEAR-MILLIMETER WAVE FREQUENCIES. INVESTIGATIONS WILL BE CONDUCTED FOR THE EVALUATION ...

ECHELLE SPECTROGRAPHS DESIGNED FOR THE VACUUM ULTRAVIOLET HAVE BEEN LIMITED IN THEIR USEFULNESS DUE TO LOW EFFICIENCY AND STRAYLIGHT OF THE ECHELLE GRATING. THIS PROJECT APPLIESNEW APPROACHES IN COATING TECHNOLOGY AS A MEANS TO PROVIDE IMPROVED DEVICES. THE R&D EFFORT INCLUDES THE STUDY OF VACUUM DEPOSITION CONDITIONS AND THEIR RELATIONSHIP TO THE RULEABILITY OF ECHELLE GROOVES. SEVERAL TEST COATI ...

A MODIFIED FOURIER TRANSFORM MASS SPECTROMETER FOR ANALYSIS OF COMPLEX FUEL MIXTURES IS PROPOSED. THE INSTRUMENT WOULD BE CAPABLE OF RESOLVING 3,000 MIXTURE COMPONENTS OVER THE MASS RANGE M/E 100 TO M/E 600 IN A SCAN TIME OF 2.1 MINUTES,WITH A RESOLVING POWER OF 268,000 (FWHH CRITERION) AT M/E 300. EXACT MASS MEASUREMENT AND DETERMINATION OF ATOMIC COMPOSITIONS FOR EACH RESOLVED SPECIES WOULD BE C ...

THE TRANSFER OF TISSUE CULTUIRED PLANTS FROM IN VITRO TO OPEN GREENHOUSE ENVIRONMENTS IS FREQUENTLY A MULTI-STAGED, LABOR INTENSIVE PROCESS THAT CAN RAISE PRODUCTION COSTS TO COMMERCIALLY PROHIBITIVE LEVELS. RESEARCH IS UNDERWAY TO TEST THE FEASIBILITY OF DEVELOPING A CONSOLIDATED, COST- EFFECTIVETRANSFER PLUG SYSTEM THAT WILL ALLOW PLANTS TO BE TRANSFERRED, ROOTED, INOCULATED WITH BENEFICIAL MYCO ...

IN THIS PHASE I EFFORT WE PROPOSE TO DEMONSTRATE THE TECHNICAL FEASIBILITY OF A PASSIVE REMOTE SENSING INFRARED DEVICE THAT ACCURATELY AND IN REAL-TIME PROFILES ATMOSPHERICTEMPERATURE, HUMIDITY, AND REFRACTIVE INDEX. THIS PROPOSED EFFORT IS A LOGICAL EXTENSION OF A PREVIOUSLY SUBMITTED THEORETICAL AND NUMERICAL ALGORITHM STUDY WITH THE ARMY RESEARCH OFFICE. SINCE THEIR CHARTER IS FOR BASIC THEORET ...
