Decision support for the management of aging nuclear critical infrastructures: vulnerability assessment and multi-criteria decision analysis

Because many nuclear facilities are nearing the end of their design life, it is important to assess the vulnerability of these aging critical infrastructure systems. The risks associated with nuclear energy are often complex and uncertain, including the release of radioactive fission, and environmental issues related to the longevity and toxicity of waste products. In the event of a nuclear accident, the environmental degradation, social dislocation, and economic losses could be enormous. It follows that a comprehensive multiple-criteria decision analysis (MCDA) is valuable to assess system vulnerabilities and to integrate social and economic variables. Decision support systems (DSS) for MCDA can help improve the management of aging critical infrastructure systems, thereby promoting a more secure and efficient nuclear energy lifecycle.
