Keywords:Decommissioning, Cost estimation, DECOST

We investigated each decommissioning process costs, such as scabbling cost and equipment dismantling cost that based on actual dismantling of nuclear fuel cycle facility. In addition, the each process costs in the facility were estimated using the DECOST (simplified decommissioning cost estimation code for nuclear facilities). The estimated results were comparison with the actual cost data, and the accuracy of the estimated value from the DECOST was evaluated for each cost.
