原子力機構における核燃料サイクル施設の解体実例に基づき、はつり費や設備解体費などの工程別費用を整理した。また同施設の工程別費用をDECOST(原子力施設廃止措置費用簡易評価コード)を用いて見積もり、先の整理結果と比較した。比較結果から、DECOSTの工程別費用の見積り精度などを評価した。

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.
