Integrated digital control room with human-in-the-loop for effective SMR operation

This study introduces an integrated Digital Control Room (DCR) for improved operation performance of Small Modular Reactor (SMR). The Integrated DCR framework encompasses human performance monitoring, semantic reasoning, and adaptive controls into a single system with the considerations of human factors within the context of intelligent automation. The proposed design includes Human Performance Management System (HPMS), Human Performance Semantic Network (HPSN), Human Monitoring System (HMS), Human Simulation (HSIM), Control Room Controller (CRC), and External Environment Interface (EEI). The interactions among these modules provide an effective closed loop for effective and optimum SMR operation. The integrated monitoring system enables real-time assessment of operator performance metrics including stress, workload, and situational awareness, and link these with plant and environmental conditions. Operational scenarios are modeled using a co-simulation environment and integrated with SMR simulator for Integral Pressurized Water Reactor (iPWR) from IAEA, to assess operator states and their correlation with environmental changes and required adaptive control room configurations.
