An Investigation of Operator Situation Awareness Utilizing the Fuzzy Comprehensive Evaluation Method

Abstract

The escalating complexity of power grids underscores the growing reliance on nuclear power for stability, highlighting the critical role of situational awareness in nuclear safety and operator well-being. Deficiencies in this awareness can result in incidents that threaten plant operations and workforce health, emphasizing the need for its enhancement to ensure operational efficiency and worker protection in a high-stakes industry. This research systematically identifies and categorizes factors contributing to situational awareness gaps using interdisciplinary principles. Analyzed within a stratified framework, these factors are targeted for improvement through procedural enhancements, team collaboration, knowledge exchange, and training, with the aim of bolstering safety and occupational health outcomes. The study introduces a three-tiered framework that identifies 22 Precursory Influencing Factors (PIFs) across four critical categories, addressing the safety and health challenges operators encounter in dynamic operational contexts. This framework is designed to proactively manage occupational health risks, thereby fostering a safer work environment and safeguarding the operational integrity and long-term health of nuclear plant personnel. By employing the Fuzzy Comprehensive Evaluation Method, the findings provide substantial insights for advancing nuclear power plant management, particularly concerning occupational health and safety. The study establishes a foundational framework for robust safety management, focusing on the well-being of operators. Anticipated outcomes include elevated safety standards and a culture prioritizing occupational health, leading to increased reliability, integrity, and a healthier work environment in nuclear operations.
