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.
