SwRI-led team to use drones to assess Fukushima nuclear plant

Staff Writer |
Southwest Research Institute (SwRI) is leading a team to develop unmanned aerial system (UAS) technology to fly into the containment vessels of the damaged units at the Fukushima Daiichi nuclear power station in Japan 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.

SwRI Intelligent Systems Division senior research engineer Monica Garcia said: “This is a formidable challenge.

“The conditions inside the containment at Fukushima Daiichi are quite possibly the most challenging environment that the SwRI-Penn team has had to address. We will be pushing the envelope in terms of the technology.”

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. However, damage and high radiation levels have limited access to information vital to decontamination and decommissioning efforts.
