AbstractIn the course of the emplacement of radioactive waste containers in a large store some kind of radiation minimization can be obtained . Since the filling of a real store can last as long as 10 years,the procedures of emplacement mustbe simulated in order to verify the quality of the optimization . Some results are reported of emplacement computer experiments with simulated sequences of radioactive waste containers and container batches and with different emplacement strate gies.
