THIS PROJECT IS AIMED AT DESIGNING A LIGHT WEIGHT AND COMPACT NEGATIVE ION CYCLOTRON USING A SUPERCONDUCTING MAGNET. THE PROPOSED CYCLOTRON WILL COST 25% LESS THAN EXISTING RESISTIVE MAGNET CYCLOTRONS, WILL OCCUPY 50% LESS SPACE, AND WILL WEIGH APPROXIMATELY 4000 LBS COMPARED WITH 40,000 LBS FOR THE CONVENTIONAL CYCLOTRON. THE NEW CYCLOTRON OPERATING EXPENSE WILL BE SLIGHTLY LESS THAN THE OPERATIN ...

THE SPECIALIZED CONFIGURATION OF THE CTT (COMPACT IGNITION TOKAMAK) PLASMA CHAMBER WITH ITS LIMITED ACCESS SPACE, HIGH RADIATION LEVELS, AND HIGH VACUUM CONDITIONS REQUIRES THE DEVELOPMENT OF SPECIAL PURPOSE REMOTE-HANDLING EQUIPMENT. INITIAL ASSEMBLY OF THE VACUUM VESSEL AND PORT PLUS IN-VESSEL INSPECTION/MAINTENANCE OF FIRST-WALL COMPONENTS, DIVERTOR, DIAGNOSTICS, AND RADIO FREQUENCY LAUNCHER AR ...

N/A

IT IS PLANNED TO DEVELOP A WORKSTATION ENVIRONMENT FOR THE ADVANCED THERMAL HYDRAULIC ENERGY NETWORK ANALYZER (ATHENA) CODE TO FACILITATE FUSION REACTOR DESIGN STUDIES. ATHENA HAS A WIDE RANGE OF CAPABILITIES AND IS AN ESSENTIAL TOOL FOR THE STUDY OF FUSION REACTOR DESIGN. THE PERSONAL-COMPUTER (PC)-BASED WORKSTATION ENVIRONMENT FOR ATHENA WILL STREAMLINE AND AUTOMATE THE DEVELOPMENT OF INPUTDECKS ...

THIS RESEARCH ADDRESSES THE NEED FOR OXYGEN SENSORS TO PROVIDE HIGHLY LOCALIZED, RAPID SENSING (ON THE MICRON SCALE) WHILE OPERATING IN A CORROSIVE ATMOSPHERE AT ELEVATED TEMPERATURE AND/OR PRESSURE. THE MATERIALS USED WILL BE IN THE FORM OF COMPLEX EUTECTIC THIN-FILMS. AN INTENSE LASER BEAM WILL BE USED TO SOLIDIFY DIRECTIONALLY EUTECTIC FILMS OF ZRO(2) WITH MO, ZRC, AND ZRN. TWO OF THESE THREE S ...

FUSION ENERGY POWER REACTORS WILL REQUIRE HIGH SPEED VACUUM PUMPS TO EXHAUST REACTION PRODUCTS FROM THE PLASMA. CRYOGENIC PUMPS, WHICH FREEZE GASES ON A LOW TEMPERATURE SURFACE, ARE POTENTIALLY VERY ATTRACTIVE FOR THIS TASK. HOWEVER, THEY MUST BE REMOVED PERIODICALLY FROM SERVICE TO BE REGENERATED (DEFROSTED), OTHERWISE THEY EITHER SATURATE OR ACQUIRE AN UNACCEPTABLY HIGH INVENTORY OF RADIOACTIVE ...

CURRENTLY AVAILABLE AUTHORING SYSTEMS HAVE BEEN PROVEN EFFECTIVE IN PRODUCING COMPUTER-BASED TRAINING LESSONS CONTAINING SEQUENCES OF TEXT AND GRAPHICS SCREENS THROUGH WHICH THE STUDENT IS GUIDED UNTIL MASTERY IS ACHIEVED. IN A PERSONNEL TRAINING SIMULATION, FAR MORE ADVANCED CAPABILITIES ARE REQUIRED, INCLUDING MULTITASKING, COMMUNICATION WITH EXTERNAL DEVICES, HIGH SPEED DATA ANALYSIS AND GRAPHI ...

N/A

THE DEVELOPMENT OF NOISE ANALYSIS FOR IN-SITU RESPONSE TIME TESTING OF SAFETY SYSTEM PRESSURE SENSORS IN NUCLEAR POWERPLANTS IS UNDER WAY. THE TECHNIQUE IS BASED ON RECORDING THE NATURALLY OCCURRING FLUCTUATIONS THAT EXIST AT THE OUTPUT OF PRESSURE SENSORS AS THE PLANT IS OPERATING. THESE FLUCTUATIONS CAN BE ANALYZED TO GIVE THE SENSOR TRANSFER FUNCTION FROM WHICH THE SENSOR RESPONSE CAN BE DETERM ...
