Analysis of nuclear fire safety by dynamic complex algorithm of fuzzy theory and system dynamics

The cognitive architecture is investigated for the disaster management in the nuclear accident site. The fire-based nuclear facility catastrophe is a very significant considerable factor in the aspect of the nuclear safety. There are simulation results as the graphs by each time step composing of the simulations of 3 factors of Fire Caution, Fire Control, and Personal Factor. Each graph shows the instability of the designed event. There is the simulation result for Instability of Fire Protection System. The highest value is 0.67584 in 56th year in which the system is very unstable in fire protections. In the graph, the later time part of the operations has higher values comparatively. This could be explained by the system aging of the plant. In the system dynamics (SD) method combined with fuzzy set algorithm, the tractable modeling is liable to be adapt to any kinds of situations in the NPPs. Needless to say, the complex algorithm could be usable in the cases of normal as well as emergency circumstances.
