Scheduling the Disposal of the Spent Nuclear Fuel with Interactive Multiobjective Optimization

Outi Montonen, Timo Ranta, Marko M. Mäkelä, Scheduling the Disposal of the Spent Nuclear Fuel with Interactive Multiobjective Optimization. TUCS Technical Reports 1204, TUCS, 2019.

Abstract:

Several countries utilize the nuclear power and face the problem what to do with the spent nuclear fuel. One possibility, which is under the scope in this paper, is to dispose the fuel assemblies in the disposal facility. Before the assemblies can be disposed, they must cool down their decay heat power in the interim storage. Next, they are loaded into canisters in the encapsulation facility, and finally, the canisters are placed in the disposal facility. In this paper, we model this process as a multiobjective mixed integer nonliner optimization problem with minimization of nine objectives: maximum number of assemblies in the storage, maximum storage time, average storage time, total number of canisters, end time of the encapsulation, operation time of the encapsulation facility, lengths of disposal and central tunnels, and total costs. As a result, we obtain the disposal schedule i.e.~amount of canisters periodically. We introduce the interactive multiobjective optimization method using the two-slope parameterized achievement scalarizing functions which enables us to obtain systematically several different Pareto optimal solutions from the same preference information. Finally, a case study adapting the disposal in Finland is given. The results obtained are analyzed in terms of the objective values and the disposal schedules.
