Abstract: The paper analyzes the present situation of radioactive wastes in Qinshan nuclear power base and its processing and storage,and focuses on the volume reduction technology for large number of solid wastes including steamed residual liquid condensates,compressible waste and waste resin.Research shows that there is great potential for volume reduction of radioactive wastes in Qinshan nuclear power base,and the volume reduction scheme is provided.With the proposed scheme,the storage capacity for solid wastes in Qinshan nuclear power base can be increased by more than 5 years,which will effectively relieve the pressure for waste storage capacity.
