COMMON CAUSE FAILURE ANALYSIS (CCFA) IS AN IMPORTANT ELEMENTOF A COMPLETE PROBABILISTIC RISK ASSESSMENT (PRA) SINCE COMMON CAUSE FAILURE IS OFTEN A DOMINANT FACTOR IN THE RISK POSED TO PUBLIC HEALTH AND SAFETY FROM NUCLEAR POWER PLANT ACCIDENTS. A MAJOR PROBLEM ASSOCIATED WITH PERFORMING A CFFA IS THE ABSENCE OF SUPPORTING QUALITATIVE OR QUANTITATIVE COMPONENT FAILURE DATA. EXTENSIVE AMOUNTS OF CO ...

INSTRUMENTS BASED ON THE SEEBECK EFFECT HAVE BEEN USED SUCCESSFULLY IN EUROPE AND THE UNITED STATES TO IDENTIFY ALLOYS THAT HAVE BEEN HARDENED BY HEAT TREATMENT OR COLD WORKING. BECAUSE THE RESULTS OF RADIATION DAMAGE, INCREASED YIELD STRENGTH AND DECREASED TOUGHNESS ARE SIMILAR, AN INVESTIGATION IS PROPOSED TO EXAMINE THE FEASIBILITY OF USING THE SEEBECK EFFECT IN THE ASSESSMENT OF RADIATION DAMA ...

THIS PROPOSAL IS PREPARED IN DIRECT RESPONSE TO THE NRC'S SOLICITATION FOR AN IMPROVED DEVICE TO MEASURE AIR MOVEMENT FOR PERSONNEL RADIATION PROTECTION AND HEALTH PHYSICS APPLICATIONS IN NUCLEAR FACILITIES. THE PURPOSE OF THE NEW DEVICE IS TO PROPERLY LOCATE AIR SAMPLERS SO THAT THE AIR SAMPLED IS REPRESENTATIVE OF THE AIR INHALED BY WORKERS. ALTHOUGH AIR FLOW RATE SENSORS SUCH AS ANEMOMETERS ARE ...
