Description

The Japan Atomic Energy Agency has various nuclear facilities such as research reactors, nuclear fuel facilities and research facilities. Some aged facilities will be decommissioned after their original functions ended, and it is necessary to evaluate decommissioning cost to draw up decommissioning plan. We have developed an evaluation method called DECOST code that can efficiently calculate the decommissioning cost in a short time based on factors such as features and similarity of the facilities and dismantling methods. This report is as a user manual of the DECOST code prepared for improving convenience. Here, outline of DECOST code and input data for evaluation such as facility information and dismantled waste amount and evaluation formulae used in DECOST are presented. In addition, the preparation method of the input data is also shown. (author)

Abstract (Japanese)

日本原子力研究開発機構は、原子炉施設, 再処理施設, 核燃料施設, 研究施設等の原子力施設を有している。これら施設は施設の使用目的の終了や老朽化等により、いずれ廃止措置を行うことになるが、廃止措置に先立ち、廃止措置費用を評価する必要がある。これまでに、施設の特徴や類似性、解体工法等を基に廃止措置費用を短時間で効率的に計算できる評価手法(DECOST)を開発してきた。本報告書は、DECOSTの利便性向上を目的に、利用マニュアルとして作成した。DECOSTで用いる評価式を提示し、評価の対象となる原子力施設の種類ごとにその利用方法を具体的に解説した。加えて、評価の際に必要となる施設情報や解体廃棄物量等の設定方法も示した。(著者)
