Unitization for portability of emergency response surveillance robot system: experiences and lessons learned from the deployment of the JAEA-3 emergency response robot at the Fukushima Daiichi Nuclear Power Plants

摘要

It was cleared that transportability of emergency response robots system had been very important. Therefore, RESQ series robots, which were developed by Japan Atomic Energy Research Institute (present, Japan Atomic Energy Agency: JAEA), were installed or stored in containers for easy transportation to the accident site. After Fukushima Daiichi NPPs’ accidents occurred, JAEA modified a RESQ-A robot in order to meet the situation of the accidents with consideration of transportation. However, actual situation was beyond the anticipation, and unitization was required to deploy JAEA-3 robot to Fukushima daiichi NPPs. The actual confused situation was many rubble were scattered and temporary cables and hoses were constructed in the reactor buildings, so that reconnaissance robots should be conveyed by operators through limited route, should be reassembled in short time. JAEA modified again in order to unitize JAEA-3 robot system in Fukushima daiichi NPPs. It was lesson learned that emergency response robot system needed to be unitized for increase of portability, and that “Unitization policy for emergency response robot system” was developed.
