A METHOD TO OPTIMIZE ROBUST CORE DESIGN PERFORMANCE BASED ON DESIGN FOR SIX SIGMA (DFSS) METHODOLOGY

摘要

This paper provides the detailed information about the methodology of newly developed Robustness Evaluation Module of ePrometheus™. It summarizes the background and motivation of the work, Robust Core Design Description based on Design For Six Sigma (DFSS) methodology, design basis assumptions, historical simulation uncertainties in the reactor operations, development of robustness methodology and robustness metric for optimization response surfaces, opportunities and defect definition based on robustness performance and calculate statistical long-term process capability predictions based on DFSS methodology. A new ePrometheus™ prototype has been developed and incorporates this method as a modular functionality.
