ALTHOUGH THE ASP (ACCIDENT SEQUENCE PRECURSOR) METHODOLOGY FOR ANALYZING OPERATIONAL DATA AND EVENTS FOR PRECURSORS TO SEVERE ACCIDENTS HAS BEEN IN EXISTENCE FOR ABOUT A DECADE, IT DOES NOT NOW INCORPORATE THE ANALYSIS OF PRECURSORS TO EARTHQUAKE-INITIATED AND INTERNAL-FIRE-INITIATED ACCIDENT SEQUENCES. THIS PROJECT'S OBJECTIVE IS TO FILL THIS GAP BY DEVELOPING SUCH A METHODOLOGY. THE OBJECTIVE OF ...

THE OBJECTIVE OF THIS PROJECT IS TO DEVELOP A MEASUREMENT-BASED METHODOLOGY AND A TOOL SET TO IMPLEMENT THE METHODOLOGY FOR PROBABILISTIC ANALYSIS OF OPERATIONAL DATA FROM NUCLEAR FACILITIES TO PROVIDE SYSTEMATIC AND OBJECTIVE EVALUATIONS OF RELIABILITY AND AVAILABILITY. THE RESULTS WILL BE A PARTICULAR USE FOR DEDICATION OF COMMERCIAL GRADE DIGITAL INSTRUMENTATION AND CONTROL (I&C) SYSTEMS IN NUC ...

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 PROPOSED PROJECT WILL DEMONSTRATE THE FEASIBILITY OF EMPLOYING ELECTRON TRAPPING (ET) MATERIALS WITH FIBER OPTICS FILAMENTS FOR USE AS MICROPROBE RADIATION DOSIMETERS.THE ET MATERIALS TM CAN BE INTERROGATED BY NEAR-INFRARED TO PRODUCE VISIBLE OUTPUT SCALABLE TO RADIATION DOSES AT THE FIBER TIP. PHASE I WILL ASSESS THE PERFORMANCE OF SUCH MATERIALS AS MICROPORBE RADIATION DETECTORS INTEGRATED W ...
