AN ALPHA/BETA RADIATION DETECTOR SUITABLE FOR USE IN THE INSTRUMENT CHANNEL OF A FIBEROPTIC ENDOSCOPE WILL BE WILL BE DEVELOPED TO PROVIDE IN-VIVO IN-SITU BIOASSAY MEASUREMENTS LEADING TO COMPUTER-ASSISTED ESTIMATES OF IN- TERNAL DOSE AND DISTRIBUTION IN THE RESPIRATORY AND GASTRO- INTESTINAL TRACTS. DURING PHASE I OF THE PROGRAM, ALPHA AND BETA PARTICLE SENSITIVE SCINTILLATING PLASTIC FIBERS WILL ...

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 ...

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 PROPOSAL IS TO CONDUCT RESEARCH ON POLYCULTURE OF OYSTERS IN PONDS WITH MARINE SHRIMP. SURVIVAL OF OYSTERS IN STATIC WATER PONDS IS LOW, BUT IT IS ANTICIPATED THE SURVIVAL AND GROWTH WILL BE GOOD IN PONDS WHERE AERATION DEVICESCAUSE WATER TO CIRCULATE WITHIN THE POND. BESIDES THE OBV IOUS ECONOMIC BENEFIT TO BE DERIVED FROM THE SALE OF OYSTERS, BENEFITS TO GENERAL POND PRODUCTIVITY ARE ANTICIP ...
