PROCESS DATA RECONCILIATION (PDR) - AN INNOVATIVE DIGITAL TOOL FOR PLANT MONITORING AND OPTIMIZATION AS THE BASIS FOR CONTRADICTION-FREE PLANT BALANCE REPORTS

Abstract

Process Data Reconciliation (PDR) is the only tool for the reconciliation of all technical processes and other scientific applications to achieve "Contradiction-free and quality-controlled data with the lowest possible uncertainty". The theory of the PDR method is based on the Gaussian correction principle. Several examples will be shown on how PDR can be used in a customer-oriented way at nuclear power plants. The use of reconciled values as basis for correction factors will be described. The way to achieve acceptance by plant staff and regulatory authority will be discussed. One of the most important objectives in a PDR project is how to visualize the results and communicate this information within the organization.
