Following up on a telescopic probe and obstacle removal robot, TEPCO will insert a new robot which looks like a scorpion to further investigate inside the Unit 2 PCV. This is a new challenge for TEPCO that the robot will try to obtain information on the reactor by getting visual image and measuring temperature and radiation level.
Ideally, TEPCO needs to identify where the melted fuels are located inside the reactor in order to research and develop the technology to remove the fuels. And this will also welcome more progressively on international collaboration and partnerships.
Scorpion shaped robot is a "symbol" of new challenge that TEPCO is going to face for the decommissioning the site. The information which will be obtained from its cameras will allow TEPCO to further understand the condition of the Unit 2.
In addition, investigation will be held in a safe manner that robot will be inserted inside the PCV and the radiation will remain at the same area.
Every step is a new challenge for TEPCO but TEPCO welcomes the challenge. There are lessons to be learned every day. But "technology" such as robots are constantly evolving. And TEPCO will keep moving forward.
