SAFETY SYSTEM TEMPERATURE SENSORS IN NUCLEAR POWER PLANTS ARE SUBJECT TO PERFORMANCE DEGRATION BECAISE PF AGING EFFECTS. A PROGRAM OF LABORATORY TESTING AND IN-SITU TESTINGIS NEEDED TO ENSURE THAT AGING DOES NOT LEAD TO REDUCED SAFETY AND AVAILABILITY. MUCH OF THE TECHNOLOGY NEEDED FOR THIS PROGRAM NOW EXISTS AS ISOLATED METHODS AND PROCEDURES. THESE WILL BE USED IN THIS PROJECT TO PERFORM AN AGIN ...

PERIODIC RESPONSE TIME TESTING HAS BEEN PERFORMED FOR THE PAST TWELVE YEARS ON THE SAFETY SYSTEM PRESSURE SENSORS IN MANY NUCLEAR POWER PLANTS. HOWEVER, THE RESULTS OF THESE TESTS ARE NOT RELIABLE FOR ASSESSMENT OF AGING EFFECTS. THEIS BECAUSE INADEQUATE METHODS AND PROCEDURES HAVE BEEN USED IN PERFORMING THE MAJORITY OF THE TESTS. THIS PROPOSAL OFFFERS AN EXPERIMENTAL RESEARCH PROJECT TO PROVIDE ...

A RESEARCH PROJECT IS PROPOSED TO EVALUATE THE SUITABILITY OF NEWLY DEVELOPED SMART SENSOR TECHNOLOGIES FOR BOTH OF THEFOLLOWING NUCLEAR POWER PLANT APPLICATIONS: MANAGEMENT OF AGING DEGRADATION OF SAFETY SYSTEM TEMPERATUREAND PRESSURE SENSORS IN CONVENTIONAL LWRS SMART TEMPERATURE AND PRESSURE SENSORS FOR ADVANCED LWRS. THE PROJECT WILL ADDRESS BOTH THE CALIBRATION DRIFT AND RESPONSE TIME DEGRADA ...

An effective surface flow controller for the manipulation of the properties of aerodynamic boundary layers, particularly the resulting body drag and airflow attachment, has been long sought after. The goal has always been a surface airflow controller that is able to manipulate the aerodynamic boundary layer while both saving fuel (reducing power consumption) and improving the aircraft performance ...

Atmospheric Glow Technologies proposes to develop the Plasma Agent Neutralization Elimination (PLANE) System based upon its patented One Atmosphere Uniform Glow Discharge Plasma (OAUGDP) technology. When developed, this advanced design will serve as a system for the decontamination of aircraft and associated cargo. AGT has demonstrated the success of OAUGDP in decontaminating various substrates ...

THE VLSI AND VHISC DEVELOPMENT PROGRAMS OF THE AIR FORCE REQUIRE CHARACTERIZATION OF III-V COMPOUNDS WITH AN INTERFERENCE FREE, HIGHLY SENSITIVE ELEMENT ANALYSIS TECHNIQUE HAVING GOOD LATERAL AND DEPTH RESOLUTION. SPUTTER INITIATED RESONANCE IONIZATION SPECTROSCOPY (SIRIS), AN ULTRASENSITIVE ANALYTICAL TECHNIQUE DEVELOPED BY ATOM SCIENCES, HAS BEEN DEMONSTRATED IN SILICON TO HAVE GOOD SENSITIVITY ...

THE VAPOR SPACE INSIDE AN AIRCRAFT FUEL TANK EITHER IS OR IS NOT FLAMMABLE (OR EXPLOSIVE) DEPENDING UPON THE PERCENTAGE OF FUEL VAPOR AND OF OXYGEN OF INERT GAS SUCH AS NITROGEN OR CARBON DIOXIDE. IT IS IMPORTANT TO KNOW THESE PERCENTAGES WHEN TESTING THE EFFICACY OF EXPERIMENTAL INERTING MEASURES BY FIRING LIVE ROUNDS AT TEST TANKS; BUT THERE IS NO FAST, CONVENIENT, FIELD METHOD OF MEASURING THE ...

THE MISSION OF THIS PHASE I PROJECT IS COMPLETION OF A TRULY INNOVATIVE STUDY TO UPGRADE EXISTING PNS CODES FOR COMPUTING HIGHSPEED, THREE-DIMENSIONAL RE-ENTRY FLOWFIELDS. THE PLAN OF ACTION ENCOMPASSES A THOROUGH EXAMINATION OF THE RANGE OF ADMISSABLE CFD THEORIES, TO UNEQUIVACALLY COMPARE STRONG AND WEAK POINTS FOR APPLICATION TO THE REYNOLDS-AVERAGED NAVIER-STOKES EQUATIONS WITH DIFFERENTIAL EQ ...

Superconducting coils are capable of storing considerable amounts of energy. Should a coil quench, due to overheating or exceeding the critical field or current, the stored energy in the coil must be dissipated safely - without endangering personnel or damaging the coil or control systems. In any superconducting coil design, it is essential to design and build the system such that limits of the ...

Military applications of high power millimeter-wave directed energy weapons technologies require high field superconducting magnets that are incorporated in gyrotron devices. The magnets must be cooled to cryogenic temperatures to operate, giving rise to several technical challenges. Gyrotron magnets have traditionally required a relatively long time to cool-down (typically at least 24 hours) an ...
