SwRI team to develop drones for Fukushima NPP

11 April 2018

A team led by Southwest Research Institute (SwRI) is developing unmanned aerial system (UAS) technology to fly into the containment vessels of the damaged units at Japan’s Fukushima Daiichi nuclear power station and assess conditions. Tokyo Electric Power Company Holdings, Incorporated (TEPCO Holdings) contracted SwRI to explore the use of UAS, or drones, within the containment. Working with the General Robotics, Automation, Sensing and Perception (GRASP) Lab at the University of Pennsylvania (Penn) School of Engineering and Applied Science, SwRI engineers are helping adapt small drones to autonomously operate within the containment.

When a 9.0 magnitude earthquake and a tsunami with estimated wave heights of 13 meters struck the power station in 2011, this one-two punch initiated a series of events that ultimately caused three reactors to fail. Since then, a number of ground- and underwater-based robotic systems have been sent inside the containment.

The team successfully demonstrated the core feasibility of their approach in a test fixture at SwRI’s San Antonio campus late last year. During Phase 1 of the project, the team also verified that the UAS components could survive the harsh radiation conditions within the containment.
