Abstract: From the point of view of radioactive waste minimization, the loading process of pellets resulted from waste supercompaction in a NPP is simplified into a bin-packing issue. In combination with the optimal algorithm of descending order, an optimized scheme of loading is proposed, and simulation operations are carried out. The results show that the scheme can significantly improve the loading rate of repackaging drums. The feasibility of the scheme is proved by comparison and analysis of the storage, transportation and loading efficiency of waste pellets.
