JMTR原子炉建家の換気設備である送風機シャフト部の摩耗に係る補修を溶射方法により行い、施設内作業が可能かつ短期間で実施できたことから、高経年化した廃止措置施設の設備・機器の維持管理に有効な方法であることを実証した。

The blower shaft, which is part of the ventilation system in the JMTR reactor building, was refurbished using a thermal spraying technique to address wear damage. By applying this method, the repair was successfully conducted on-site within a short time frame. The results demonstrate that thermal spraying is an effective maintenance technique for equipment and components in aging decommissioning facilities.
