PARAMETER IDENTIFICATION TECHNIQUE, A NEW APPROACH TO WEAR MEASUREMENT IN LMFBR

THIS PROPOSAL IS CONCERNED WITH EVALUATION OF THE FEASIBILITY OF, AND IDENTIFICATION OF THE REQUIREMENTS FOR THE DEVELOPMENT OF NEW TECHNIQUE FOR EARLY DETECTION OF DEGRADATION AND WEAR IN LMFBR EQUIPMENT. DUE TO THE NONDETECTABILITY OF THE AGING MECHANISM VIA PRESENT SURVEILLANCE METHOD, THERE IS AN ESSENTIAL NEED TO INVESTIGATE NEW APPROACHES FOR WEAR MEASUREMENT. THE METHOD TO BE EMPLOYED HERE IS PARAMETER IDENTIFICATION TECHNIQUE USING REGRESSION MODEL TO ANALYZE REACTOR NOISE DATA. IT IS EXPECTED THAT AS A RESULT OF THIS RESEARCH STUDY, A SURVEILLANCE PROCEDURE TO BE DEVELOPED FOR ON-LINE OR IN-SERVICE MONITORING OF EQUIPMENT WEAR OUT, WITH MINIMUM COST DUE TO UTILIZATION OF SENSORS AND MEASUREMENT INSTRUMENTATION THAT ARE PART OF NORMAL OPERATION INSTRUMENTATION AND ARE ALREADY INSTALLED IN THE REACTOR. THE FINAL RESULT WILL HAVE AN INDUSTRY WIDE APPLICATION DUE TO THE EASE OF IMPLEMENTATION OF THE METHOD AND DUE TO THE APPLICABILITY OF THE TECHNIQUE TO OTHER TYPE OF REACTORS (LWR) AS WELL AS LMFBR.
