AS NUCLEAR PLANTS GROW OLDER, ENVIRONMENTAL CONDITIONS MAY AFFECT THE PERFORMANCE OF PLANT CONCRETE AND STEEL STRUCTURES. WE PROPOSE TO DEVELOP A STRATEGY WHICH CAN BE APPLIED TO CONCRETE STRUCTURES. IT WILL BE DIRECTED TOWARDSTHE DEVELOPMENT OF METHODS TO ANALYZE AND UNDERSTAND AGING EFFECTS, INCLUDING THE COMBINED EFFECTS OF TIME, TEMPERATURE, RADIATION, HUMIDITY, STRESS, CHEMICAL ENVIRONMENT AN ...

THE IDENTIFICATION OF THE TYPE OF PRECIPITATION (RAIN, SNOW, FOG/HAZE, HAIL) HAS TRACTIONALLY RELIED ON HUMAN JUDGMENT. RECENTLY, THE WAVE PROPAGATION LABORATORY OF DEVELOPED A TECHNOLOGY FOR AUTOMATIC WEATHER IDENTIFICATION USING LASER SCINTILLATION AND SCATTERING. THE TECHNIQUE HAS BEEN SUCCESSFULLY TESTED IN FIELD OPERATION. HOWEVER, THE SYSTEM IS TOO CLUMSY AND EXPENSIVE FOR LARGE-SCALE FIELD ...

N/A

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 ...

N/A

OVER THE LAST 5 YEARS, A NUMBER OF ULTRASONIC APPROACHES TO RESIDUAL AND APPLIED STRESS MEASUREMENTS USING EMATS HAVE BEEN REPORTED. NONE OF THESE HAS BEEN EVALUATED ON STEEL BUT THERE ARE NO FUNDAMENTAL REASONS WHY MOST CANNOT BE APPLIED TO STEEL. WHEN THE MEASUREMENT CONSTRAINTS IMPOSED BY MAKING MEASUREMENTS WITH A DEVICE ATTACHED TO A RAILCAR TESTING VEHICLE ARE CONSIDERED, TWO EMAT ULTRASONIC ...

WORKSTATION AND EXPERT SYSTEM TECHNOLOGIES HAVE A POTENTIAL OF SUBSTANTIALLY FACILITATING THE DEVELOPMENT AND EVALUATIONOF FAULT TREES. INTRODUCING A WORKSTATION PHILOSOPHY WITH AN INTERACTIVE SET OF INTEGRATED SOFTWARE TOOLS ON A LOCAL COMPUTER WILL PROMOTE IMPROVED CONTINUITY IN THE THOUGHT PROCESS DURING A FAULT TREE DEVELOPMENT. THE EXPERT SYSTEM TECHNOLOGY WILL SIMPLIFY THE WAY FAULT TREES AR ...

IN-REACTOR MEASUREMENTS INVOLVING ELECTROCHEMICAL POTENTIAL A NUMBER OF BOILING WATER REACTORS (BWRS) SUGGEST THAT THE WATER CHEMISTRY OF THE PRIMARY COOLANT OF EACH BWR MAY BE UNIQUE WITH RESPECT TO ITS ABILITY TO FACILITATE IGSCC AND/ OR MAY CHANGE WITH REACTOR OPERATING TIME OR AGE. THE WORK PROPOSED IS TO GATHER, REVIEW, ORGANIZE, COMPILE, C COMPUTERIZE, AND ANALYZE IN-REACTOR DATA PERTAINING ...

The DOT seeks an integrated unit capable of identifying and tracking individual vehicles with high accuracy using multiple vehicle detection inputs, including video images, radar-based detection, and vehicle-to-everything radio signal inputs (DSRC, cellular-V2X), with a deep learning-based engine to fuse collected data. To address this DOT need, Physical Optics Corporation (POC) proposes to contin ...
