Framework identifies and quantifies hazards and risks in integrated energy systems with nuclear power plants, suggesting design improvements.
Key Points
The research aims to create a framework for identifying and quantifying hazards and risks associated with integrated energy systems that utilize nuclear power plants.
Developed a hazard analysis framework combining accidentology and failure modes and effects analysis (FMEA).
Quantified explosion consequences using Bauwens-Dorofeev and TNT equivalent mass methods.
Used Gaussian atmospheric dispersion method for chemical release impact assessment.
Modelled operational disturbances affecting safety using probabilistic risk analysis (PRA).
Conducted sensitivity analysis on piping component failures in PRA model.
Identified critical hazards like hydrogen explosions and toxic chemical releases, with specific safety measures recommended.
PRA showed a maximum initiating event frequency increase of 1.15% and overall risk increase of 0.28%.
Importance measure analysis highlighted upstream pipe leak isolation components as essential for risk mitigation.
Recommended maintaining a distance of several hundred meters between nuclear plants and hydrogen facilities to reduce explosion risks.
