Technical Basis for Physical Fidelity of NRC Control Room Training Simulators for Advanced Reactors

摘要

This report provides the technical basis for physical fidelity requirements of simulator technology to train U.S. Nuclear Regulatory Commission (NRC) staff for their duties in upcoming nuclear power reactor control rooms (CRs). It assembles information from published research, expert opinion, review of next-generation CR designs, and a survey of 97 NRC resident inspectors (RI) and operator licensing examiners (OLE) to evaluate training needs, past experience with CR simulator training, and the importance of human-system interface (HSI) systems to the tasks that comprise the CR duties of RIs and OLEs. To provide a foundation for prioritizing training and evaluating simulator physical fidelity needs, the project team developed a Task/Knowledge, Skills, Abilities (KSA) Inventory and analyzed the identified inventory items in terms of difficulty to perform, importance to safety, and frequency of performance. The survey results provide an estimate of the degree and impact of differences in physical fidelity between the training simulator and the CR/simulator and assignment plants.
