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 ...

THIS PROJECT IS AIMED AT DEVELOPING TECHNIQUES FOR PREDICTING CHECK VALVE PERFORMANCE AND ITS INTERNAL COMPONENTS DEGRADATION IN PRACTICAL PIPING SYSTEMS USED IN NUCLEAR POWER PLANTS. THE MAIN FOCUS OF THE EFFORT IS TO SYSTEMATICALLY EVALUATE THE EFFECT OF UPSTREAM DISTURBANCES WHICH ARE WITHIN 10 DIAMETERS UPSTREAM. BY USING A COMBINED THEORETICAL AND EXPERIMENTAL APPROACH, GENERALIZED NONDIMENSI ...

MOTOR OPERATED GATE VALVE OPERABILITY PROBLEMS AND FAILURES AT NUCLEAR POWER PLANTS ARE A MAJOR SAFETY CONCERN AS STATEDIN NRC IE BULLETIN 85-03 AND GENERIC LETTER 89-10. THIS PROPOSAL IS AIMED AT IMPROVING GATE VALVE PERFORMANCE BY (1) DEVELOPING COMPREHENSIVE PERFORMANCE PREDICTION MODELS FOR USE OVER A RANGE OF OPERATING CONDITIONS, (2) DEFINING LIMITS, BASED ON SPECIFIC DESIGNS, BEYOND WHICH E ...

As the OPS performs audits of the pipeline operators, pursuant to the Pipeline Safety Improvement Act of 2002 and Sub-part O of the newly released 49 CFR 192, the focus is no longer on the existence of a plan, rather, it is on the existence of a process, the completion of tasks defined within those processes and the documentation that supports and/or defines the decisions associated with said acti ...

THE TIME REQUIRED FOR CLEANING, DEHUMIDIFYING AND PURGING OFCARGO HOLDS HAS A DIRECT EFFECT ON THE TURN AROUND TIME OF VESSELS CARRYING MOISTURE SENSITIVE GOODS IN PORT. THIS PROPROJECT WILL THOROUGHLY RESEARCH THE REQUIREMENTS FOR DEHUMIDIFICATION, DEVELOP DESIGN CRITERIA, DESIGN CRITERIA , DESIGN A REFRIGERANT TYPE DEHUMIDIFIER, CONSTRUCT A PROTO TYPE, AND TEST THE EQUIPMENT IN THE FIELD. PARTIC ...

COMMERCIAL AND GOVERNMENT SPACE TRANSPORTATION SYSTEMS DEPEND ON GROUND SUPPORT FOR NAVIGATION. THE GROUND SOLUTION CAN BE COSTLY AND MAY PROVIDE LESS ACCURACY THAN NEEDED. A GPS-BASED REAL-TIME AUTONOMOUS SPACECRAFT NAVIGATION SYSTEM IS PROPOSED. AN ALGORITHM WILL BE DEVELOPED WHICH COMBINES GPS-DERIVED POINT POSITION ESTIMATES WITH A PROPAGATED A PRIORI POSITION ESTIMATE. THE POINT POSITIONS ARE ...

THE PROPOSED PROJECT WILL DETERMINE THE FEASIBILITY OF DEVELOPING A LOW-COST, INTEGRATED, BAR CODE TECHNOLOGY BASED INFORMATION SYSTEM WHICH CAN BE INSTALLED ON TRANSIT VEHICLES. THE PROJECT WILL RESULT IN A SURVEY BASED APPLICATION FEATURE REQUIREMENTS DEFINITION, A PHYSICALLY INTEGRATED HARDWARE AND OPERATING SYSTEM PLATFORM SPECIFICATION TO SUPPORT THE APPLICATIONS, A DETAILED APPLICATIONS SOFT ...

AS PAVEMENT MANAGEMENT SYSTEMS BECOME THE PRIMARY TOOL BY WHICH AGENCIES ALLOCATE THE FUNDS FOR PAVEMENT REHABILITATION, THE ACCURACY OF DISTRESS DATA. ONE OF THE LEAST EXPENSIVE BEING MANUAL DISTRESS SURVEYS. HOWEVER, MANUAL DISTRESS SURVEYS HAVE THEIR LIMITATIONS. INACCURACIES THAT ARISE IN THE ACCUMULATION AND SUMMARIZATION OF THE DISTRESS DATA CAN LIMIT OR IMPAIR ITS USE SIGNIFICANTLY. ONE WAY ...
