Improvement of nuclear decommissioning and dismantling planning via experience ex-change and optimisation methods
Worldwide lots of nuclear power reactors will be shut down and dismantled in the next years. Apart from the technical aspects of decommissioning and dismantling (D&D), the economic view is important. Therefore, project management and especially the planning of D&D are in the centre of attention. Because of the long range project of dismantling nuclear facilities, with high requirements for safety and security, an expected makespan of about 15 to 20 years and a budget with about 0.5 to 1 billion Euros per facility the planning is very challenging. Furthermore, there is very little experience in D&D project planning and execution worldwide. To meet these challenges, on the one hand experience exchange is needed to get best practices, which is essential to plan and perform D&D safely and cost-minimally. An international approach of cooperation in the optimization process of D&D could be beneficial. On the other hand, efficient planning tools are needed to generate a robust project plan under uncertainty. Therefore, we developed a decision making model that provides a calculation of a robust dismantling plan with minimal total project costs. The algorithms used combine existent experience in D&D and optimization-methods for scheduling under uncertainty.
