N2 - The use of empirical models for On-Line Monitoring (OLM) of safety critical instrumentation for calibration reduction has been investigated for over a decade. To help support the regulatory review of possible license amendments, a series of three NUREG/CRs are being developed, The first volume in this series, entitled NUREG/CR-6895 "Technical Review of On-line Monitoring Techniques for Performance Assessment Volume I: State-of-the-Art", offers a general overview of current sensor calibration monitoring technologies and their uncertainty analysis, a review of the supporting information necessary for assessing these techniques, and a cross reference between the literature and the requirements previously outlined by the NRC. Volume II, "Theoretical Issues", presents an in-depth theoretical study and independent review of the most widely used OLM techniques. It includes a presentation of the theory and further explanation of the assumptions inherent in empirical models and uncertainty quantification techniques. The third and final volume; "Limiting Case Studies", presents the results of applying OLM models to a wide variety of plant data. Specifically, Volume III summarizes six case studies investigating the effects of model development and assumptions on model performance and offers recommendations for identifying and handling these limiting cases. This paper discusses the six cases studies. Although this study is not an exhaustive review of the many issues in OLM system development, it provides a base set of considerations which must be accounted for and a method for testing these considerations with other model architectures.
