JET is now in the early stages of being decommissioned and repurposed by the UKAEA, under the JET Decommissioning and Repurposing (JDR) programme. Initially JET’s complexity precluded the use of drones but in October 2025 the first inspection drone flights took place. These began as a derisking exercise in the JET in-vessel training facility, then in the JET assembly hall, and finally around the exterior of the JET torus itself, in late November. RAICo led a project to conduct inspection flights, to gather safety inspection data and establish the processes to support future inspections for decommissioning activities. These flights and the lessons learned pave the way for aerial drone use at JET, and in fusion engineering and decommissioning more widely.
