THIS RESEARCH SEEKS THE DEVELOPMENT AND DEMONSTRATION OF A MODEL THAT REPRESENTS THE GROUP DECISION-MAKING PROCESSES TAKING PLACE INSIDE THE CONTROL ROOM OF A NUCLEAR POWER PLANT UNDER BOTH NORMAL AND ABNORMAL OPERATING CONDITIONS. COGNITIVE DECISIONS, TEAM EFFECTS, AND DYNAMIC FEATURES ARE AMONG THE MAJOR ISSUES THAT WILL BE ADDRESSED IN THE PROJECT. THE BASIC TOOL TO BE USED IS THE INFLUENCE DIA ...

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 ...

A TWO-DIMENSIONAL NUMERICAL MODEL BASED ON A HYBRID FINITE ELEMENT METHOD WITH MESH ADAPTATION IS PROPOSED TO CALCULATE GROUNDWATER FLOW AND POLLUTANT TRANSPORT IN UNSATURATED POROUS MEDIA. THE ALGORITHM IS MODIFIED TO ENHANCE COMPUTATIONAL SPEED AND STORAGE, AND INCORPORATES PETROV-GALERKIN WEIGHTING FOR THE ADVECTION TERMS. NONLINEARITIES ASSOCIATED WITH UNSATURATED SOIL PROPERTIES, ATMOSPHERIC ...

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 ...

THE PURPOSE OF PHASE I OF THIS RESEARCH PROJECT IS TO CRITICALLY REVIEW THE EXISTING COMPUTERIZED EOP SYSTEMS FOR BOTH PWR AND BWR PLANTS, DEVELOPED BY VARIOUS NATIONAL AND INTERNATIONAL ORGANIZATIONS TO FULLY UNDERSTAND THEIR ADVANTAGES, DISADVANTAGES AND LIMITATIONS IN TERMS OF THEIR IMPACT ON OPERATORS PERFORMANCE AND RELIABILITY AND RECOMMEND ONE SYSTEM OR A COMPOSITE OF SEVERAL SYSTEMS, BEFOR ...

THIS RESEARCH WILL EXECUTE AN INDEPTH STUDY OF THE BASIC FEATURES OF EMBEDDED SYSTEM AND PLANT PROCESS SOFTWARE, INCLUDING ITS INTERACTIONS WITH THE HARDWARE SYSTEMS THAT IT IS INTENDED TO CONTROL AND REGULATE. THE PURPOSE OF SUCH A STUDY WILL BE TO IDENTIFY THE PROCEDURES AND ANALYTICAL TECHNIQUES, TO BE INTEGRATED IN AN EMBEDDED SYSTEM SOFTWARE ANALYSIS METHODOLOGY, THAT CAN BE OF GREATEST UTILI ...

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 ...

N/A

CSA PROPOSES TO DESIGN AND IMPLEMENT A STEADY-STATE SOLUTION FOR THE COMPLETE SYSTEM OF EQUATIONS SOLVED IN EITHER THE TRAC/PF1, TRAC/BD1, OF RELAP5 CODES. THE STEADY-STATE SOLUTION WILL UTILIZE THE STEADY-STATE FORM OF THE MODEL EQUATIONS AND WILL UTILIZE EXISTING EQUATION SOLVERS TO THE EXTENT POSSIBLE. ALL TIME-DEPENDENT CONSTITUTIVE AND COMPONENT MODELS WILL BE INCLUDED IN THE SOLUTION TO ENSU ...

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 ...
