Abstract: In order to ensure the safe decommissioning of reactor pressure vessel (RPV), this paper takes Qinshan Phase I RPV as the reference object, stimulates and designs packaging and radiation shielding schemes under the decommissioning plans of keeping RPV intact and dismattling RPV. This paper further compares and analyzes two schemes by estimating the operability, convenience and economy. The results show that the plan of dismantling RPV is more optimal, which could better support decommissioning of nuclear power plant.

Key words: reactor pressure vessel (RPV), decommissioning, packaging, shielding
