THE CONTRACTOR SHALL DEVELOP A FUZZY SET METHODOLOGY FOR UNCERTAINTY ANALYSIS IN PROBABILISTIC SEISMIC SAFETY ASSESSMENT OF NUCLEAR POWER PLANTS. FUZZY SET LOGIC WILL BEUSED FOR COLLECTING, QUANTIFYING AND PROPAGATING SUBJECTIVE,ENGINEERING JUDGEMENT USED IN THE UNCERTAINTY ANALYSIS. IN PHASE I, FEASIBILITY OF THE PROPOSED APPROACH WILL BE DEMONSTRATED BY APPLYING IT TO SELECTED PARTS OF A PROBABI ...

THE OBJECTIVE OF THE PROPOSED RESEARCH IS TO BUILD A USER-FRIENDLY, PERSONAL COMPUTER BASED WORKSTATION FOR PERFORMING TRAC-BWR ANALYSIS. THE SOFTWARE WILL ALLOW A USER TO READ-IN DATA FROM EXISTING TRAC-BWR INPUT DECKS (ASCII), DRAW NODALIZATION DIAGRAM, MODIFY INPUT, AUTOMATICALLY RENODALIZE THE VESSEL, CHAN AND PIPE COMPONENTS, GENERATE INPUT DECK, SUBMIT JOB, BRING BACK PLOTDATA, DISPLAY RESUL ...

LABORATORY EXPERIMENTS CONDUCTED IN A STRATIFIED TOW TANK ARE PROPOSED TO CHARACTERIZE VORTEX WAKES UNDER THE INFLUENCE OF ATOMOSPHERIC DISTURBANCE. FLOW RESEARCH HAS DEVELOPED INNOVATIVE TECHNIQUES FOR STRATIFYING THE FLUID IN THE TANK, GENERATING A CURRENT SHEAR AND CREATING AMBIENTTURBULENCE WITH GOOD CONTROL. SUCH CAPABILITIES WOULD FACILITATE THE ISOLATION OF THE EFFECTS OF THE DISTURBANCE S ...

A RESEARCH PROGRAM IS PROPOSED FOR THE DEVELOPMENT OF A VALIDATED METHODOLOGY FOR PREDICTING THE EX-VESSEL BUOYANCY-DRIVEN FLOWS IN THE HOT LEG AND STEAM GENERATOR OF A WESTINGHOUSE PLANT, AND IN THE CANDY CANE HOT LEG OF A B&W PLANT. THE PROPOSED PHASE I WORK PLAN CONSISTS OF (A) REVIEWING AVAILABLE WESTINGHOUSE EXPERIMENTAL DATA AND SIMULATING THE EXPERIMENTAL CONFIGURATION, (B) VALIDATING THE M ...

TECHNIQUES HAVE RECENTLY BEEN DEVELOPED TO ANALYZE THE 'SEISMIC MARGIN' OF A NUCLEAR POWER PLANT USING THE HCLPF CONCEPT (HIGH CONFIDENCE OF A LOW PROBABILITY OF FAILURE). STARTING WITH AN EARTHQUAKE LEVEL SHOSEN FOR MARGIN REVIEW, THE TECHNIQUE DETERMINES WHETHER THE PLANT CAN OR CANNOT 'WITHSTAND THE REVIEW-EARTHQUAKE WITHOUT CORE DAMAGE. HERE 'WITHSTAND' MEANS 'WITHSTAND WITH A HIGH CONFIDENCE ...

THE FEASIBILITY OF BUILDING A PERSONAL COMPUTER MODEL OF THEEVACUATION PROCESS WILL BE STUDIED, USING AN EXPERIMENTAL MODEL DEVELOPED BY GOURARY ASSOCIATES INC. THE RESULTING MODEL WILL PERMIT THE STUDY AND VISUALIZATION OF PASSENGER MOVEMENTS DURING EVACUATION. IT WILL ALSO ALLOW THE STUDY OF THE EFFECTS OF CROWDING, FIRE, OBSTRUCTIONS, AND OTHER EFFECTS DURING THE EVACUATION PROCESS. THE MODEL W ...

IT IS A UNIVERSALLY ACCEPTED FACT THAT THE PROPER USE OF WELL DESIGNED INFANT AND CHILD RESTRAINT SYSTEMS CAN SIGNIFICANTLY DECREASE THE RISK OF DEATH AND SERIOUS INJURY IN MOTOR VEHICLE CRASHS INVOLVING NORMAL CHILDREN. HOWEVER,WHEN PREMATURE INFANTS ARE PLACED IN SEMI-RECLINED INFANT SAFETY SEATS THERE IS A POTENTIAL FOR RESPIRATORY COMPROMISE. IN ADDITION, MANY DISABLED INFANTS ARE UNABLE TO TR ...

SEVERAL METHODS OF RAPIDLY SCREENING AIRLINE PASSENGERS AND BAGGAGE FOR EXPLOSIVE DEVICES ARE PROPOSED. TWO OF THESE METHODS USE NONLINEAR DEVICE DETECTION (NLDD) TO DETERMINE THE PRESENCE OF ACTIVE OR PASSIVE SEMICONDUCTOR DEVICES WHICH MAY BE PART OF AN ELECTRONIC BOMB FUZE. ANOTHER TWO DETECT THE PRESENCE OF RUNNING OSCILLATORS WHICH ARE LIKELY SUBSYSTEMS OF A FUZING DEVICE.

THIS PROJECT WILL DEMONSTRATE THE FEASIBILITY OF A MULTI-ZONED LINE FIRE DETECTION SYSTEM FOR AIRCRAFT. THIS WILL INCLUDE INTEGRATING THIS SYSTEM WITH A MICROPROCESSOR TO CONTROL, INTERPRET AND ANNUNCIATE THE FIRE ALARM SIGNALS.IN THIS WAY THE MULTI-ZONED DETECTION AND COMPUTER CONTROL WILL PROVIDE THE CAPABILITY TO MONITOR AND DISPLAY THE GROWTH AND SPREAD OF A FIRE IN REAL-TIME.
