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 ...

THE PROPOSED RESEARCH ADDRESSES THE APPLICATION OF ESI'S ENHANCED PARTICLE REMOVAL TO THE NON-DESTRUCTIVE DECONTAMINATION OF NUCLEAR EQUIPMENT. IN THIS PROCESS, THE PART TO BE CLEANED IS CONTACTED, UNDER CONDITIONS OF SHEAR, WITH A SOLUTION OF A HIGH MOLECULAR WEIGHT FLUOROCARBON SURFACTANT IN AN INERT PERFLUORINATED LIQUID. IT IS THEN RINSED WITH PERFLUORINATED LIQUID AND AIR DRIED. THE PERFLUORI ...

A FEASIBILITY STUDY OF USING DEVELOPED TECHNOLOGY CENTERED ON LASER HEATING OF VERY THIN THERMOLUMINESCENCE DOSIMETRY (TLD) ARRAYS FOR THE PURPOSE OF SURVEYING DECOMMISIONED AND/OR DEACTIVATED FACILITIES FOR RESIDUAL LOW ACTIVITY, SHORT RANGE RADIOACTIVE CONTAMINATION IS PROPOSED. DETECTION OF SHORT RANGE (ALPHA AND LOW BETA) PARTICLES EMITTED FROM AREAS OF LOW ACTIVITY IS DIFFICULT WITH CURRENTLY ...

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 ...

THIS PROJECT WILL RESEARCH AND DEVELOP A FLOOR MONITOR FOR QUICK DETERMINATION OF RADIOACTIVE CONTAMINATION. THE MONITOR WILL UTILIZE A NEW PORTABLE TECHNOLOGY (INCLUDING SUPPORT ELECTRONICS). IT WILL HAVE THE CAPABILITY TO MEASURE BETA CONTAMINATION BELOW 5000 DPM/100 CM SQUARED WHEN AVERAGED OVER ONE SQUARE METER AND COVER AN AREA AS LARGE AS SEVERAL SQUARE FEET PER SECOND. IT WILL ALSO BE CAPAB ...

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 ...

VANADOUS FORMATE IS USED IN THE LOMI PROCESS FOR CHEMICAL DECONTAMINATION OF NUCLEAR POWER PLANTS TO REDUCE THE EXPOSURE TO RADIATION BY PLANT PERSONNEL. IN THIS PROCESS, VANADOUS FORMATE IS USED TO PARTIALLY REDUCE IRON AND NICKEL OXIDES THAT CONTAIN RADIOACTIVE MATERIALS, PRIMARILY COBALT OXIDE. THESE METALS ARE THEN CHELATED IN SOLUTION, ABSORBED ON ION EXCHANGE RESINS, SOLIDIFIED AND BURIED. T ...

THE OBJECTIVE OF THE PHASE I EFFORT IS TO DEVELOP, IMPLEMENT, AND EVALUATE AN OPERATOR-BASED METRIC FOR ASSESSING FUTURE CONTROL ROOM AUTOMATION SYSTEMS FOR COMMERCIAL NUCLEAR PLANT OPERATIONS. THE FOCUS WILL BE ON AUTOMATION'S IMPACT ON OPERATOR UNDERLOAD AND SITUATION AWARENESS (SA). THE APPROACH COMBINES AN OPERATOR/SYSTEM BEHAVIORAL REPRESENTATION IMPLEMENTEDIN SOFTWARE, WITH A PROCEDURAL METH ...
