Tokyo Electric Power is set to commence testing of a new snake-like robot, which has been designed to use cosmic rays to help gather essential information about the damaged reactor cores' condition at Fukushima Daiichi Nuclear Power Station in Japan.

The Fukushima Daiichi decontaminating and decommissioning project involves removal of the fuel debris from units 1, 2, and 3.

The remote-controlled robot will assess the reactor cores’ condition in the nuclear plant, which was severely affected by a 2011 earthquake and tsunami, reports Associated Press.

Tokyo Electric Power chief decommissioning officer Naohiro Masuda said: "This is a great example of how the innovation and cooperation from external experts is helping us overcome challenges and make progress toward decommissioning.

"I hope that this will give us an opportunity to contribute to technological advancement and to share such progress with the rest of the world."

The project has been developed jointly by International Research Institute for Nuclear Decommissioning (IRID) and other domestic and foreign institutions.

The findings’ analysis is expected to be completed by the end of March.
