Kurion awarded robotics contract at Fukushima reactor
Kurion, a specialist in nuclear and hazardous waste management, has been awarded a contract to develop an advanced robotic arm to repair reactor primary containment leaks within the damaged Fukushima Daiichi Nuclear Power Plant.
Through a contract with Japanese industry leader IHI Corporation, Kurion will begin producing the robotic system, the Fukushima Repair Manipulator (FRM), for a targeted deployment of mid-2016 within the Unit 2 Reactor.
“Kurion is honored to be selected yet again to assist with the ongoing recovery efforts at the Fukushima Daiichi Nuclear Power Plant,” said John Raymont, Kurion founder and president.
“For the past three years, Kurion has applied our innovative technologies throughout the plant to purify hazardous water and identify repair needs. Now, the adoption of Kurion’s Fukushima Repair Manipulator marks another critical step in accelerating the ongoing cleanup of the plant.”
The Fukushima Repair Manipulator represents the second phase of the reactor primary containment leak discovery and repair efforts. In the summer of 2014 Kurion assisted in the first phase with the development and delivery of the Fukushima Inspection Manipulator (FIM), a robotic system tasked with searching for the causes of the leaks.
The primary objective of the Fukushima Repair Manipulator will be to plug leaks caused by the devastating tsunami that damaged the Fukushima Daiichi Nuclear Power Plant in March 2011.
Using cutting-edge robotics technology, the system will grant plant workers unprecedented access to the reactor to open holes, clear debris and obstacles, and plug cracks in the reactor’s vent tubes and torus - all from the safety of the remote operating station. Kurion’s sophisticated system will include a robotic arm outfitted with advanced cutting, water-jet and grouting tools; and will feature new automatic control sequences to guide these complex tasks.
“Access to radioactive and hazardous environments is a crucial piece of the waste management puzzle,” said Kurion CEO Bill Gallo. “Each project is unique, posing an engineering challenge that demands a custom robotics systems that can complete tasks where humans can’t operate."
Once the leaks are patched by the Fukushima Repair Manipulator, plant workers are expected to finally have the opportunity to remove the damaged fuel and debris from the reactor, drastically decreasing the output of contaminated water that is currently used to cool the core.
