Abstract
The safe disposal of the spent nuclear fuel is the important part of the nuclear power production. In this paper, we model the geological disposal in Finland covering objectives related to the interim storage, the encapsulation facility, the disposal facility, and the costs. A notable fact is that all the fuel types used in Finland are taken into account. The resulting optimization model is of a multiobjective nonlinear mixed integer type having eight objectives. The model is solved with the interactive method utilizing the special type of the achievement scalarizing functions. From this, we obtain a disposal schedule giving amounts of canisters to encapsulate in each time period. The results obtained are analyzed from the practical point of view.
Highlights
In Finland, the nuclear power covers the notable share of the electricity production
One way to do this is the utilization of interactive methods [3,4,5,6,7,8,9] such that the solution process moves from one Pareto optimal solution to another based on the decision maker’s wishes
We have proposed a new model for the final disposal of the spent nuclear fuel in Finland
Summary
In Finland, the nuclear power covers the notable share of the electricity production. This process produces the spent nuclear fuel which needs to be permanently disposed of safely. The multiobjective problem has several Pareto optimal solutions being all mathematically good One way to do this is the utilization of interactive methods [3,4,5,6,7,8,9] such that the solution process moves from one Pareto optimal solution to another based on the decision maker’s wishes. This lets us to avoid calculating all the Pareto optimal solutions
