Approach to optimization of risk assessment based on an evaluation matrix for decommissioning processes of a nuclear facility

Abstract This paper is intended to provide the basis for the different involved parties to reach convergence on the most relevant management option from an overall point of view and to identify which criteria should be assessed in order to appreciate that relevancy, and to promote a communication tool that benefits from the experience gained by the different countries dealing with that issue. The optimization process should be transparent among all interested parties. Through an early involvement, the process should be discussed with respective regulators and the acceptability of the management option to regulators is an integral part of the successful delivery of the project. Good practice includes making the process and decisions readily available to stakeholders.
