Selection of Sampling and Surrogate Modeling Methods for State-Point Evaluations of an AGN-201M Reactor
Nuclear reactor digital twins have been proposed for use as a safeguards technology to efficiently monitor new and novel reactors as they come online. A safeguards digital twin needs to be capable of detecting misuse and diversion as it occurs, requiring physics models to be accurate and efficient. Mathematical surrogate models are capable of achieving […]
Analysis of Human Error and Performance in Correlation with Simulator Complexity
To date, many efforts utilizing actual historical measurements, expert judgment, and simulator experiment research have been conducted to secure sufficient data for performing human reliability analysis (HRA). These days, experiment research based on full-scope simulators with actual expert operators is considered the leading method of HRA data collection. These full scope empirical studies are favorable […]
An Investigation of Time Distributions for Task Primitives to Support the HUNTER Dynamic Human Reliability Analysis
As an effort to support data collection for dynamic human reliability analysis (HRA), this study investigates time distributions for task primitives defined in the Goals, Operators, Methods, and Selection rules (GOMS)–Human Reliability Analysis (HRA) method. GOMS-HRA was developed to provide cognition-based time and human error probability information for dynamic HRA calculation in the Human Unimodel […]
