Ranking Safety Risk in nuclear facilities Using ANP Method (Case Study: Uranium Enrichment Facilities)

The purpose of the present study is to prioritize safety risk in nuclear installations using network analysis method. Evaluation of safety risk indices in nuclear installations was done using network analysis method. Related indicators are: machinery and equipment collision during extraction and excavation, temperature changes at the heart of the facility, collision of machinery and equipment with underground facility during excavation, acid and chemical injection, radiographic exposure, and exposure to radionuclides. , UV contact during welding, material deposition during flushing, environmental dyeing during painting, throwing welding sparks. The findings of the study showed that existing multi-criteria decision-making methods cannot accurately prioritize the risks. While the ANP method used in this study is not only capable of separating hazards more accurately, it can also express their importance to each other based on their degree of risk. It was found that the existing methods cannot accurately prioritize the hazards. In other words, management has no idea of the limited resources available to eliminate or control the same risks. While the proposed method in this study is not only capable of separating the hazards more accurately but also can express their importance to each other based on their degree of risk.
