The methodology commenced with exhaustive system requirements gathering to grasp the operational nuances and emergency protocols. A meticulous Petri Net representation followed, encapsulating system components and concurrent processes within a cohesive model. The framework facilitated rigorous safety checks, formal verification, and simulation-based o ptimization. Through iterative design and validation against established research, the model underwent continuous refinement. The findings illuminate the robustness of safety protocols and offer a transformative outlook on shutdown procedures, laying a foundation for further research and practical implementation to secure NPP operations. © 2024 IEEE.Control SystemsEmergency ProtocolsNuclear SafetyPetri NetsRisk ModelingSafety VerificationShutdown Procedures
