After facing serious setbacks, the Tokyo Electric Power Company, better known as Tepco, has begun an absolutely crucial operation at the Fukushima nuclear plant in Japan. This action marks a decisive moment in the long and complex process of complete dismantling of the plant that was devastated. by the Tsunami in 2011.
One of the worst nuclear disasters in modern history but the challenge is enormous inside the reactors, the radiation levels are so extreme that it would be impossible for any human being to carry out the extraction, to overcome this barrier Tepco has developed cutting-edge robotic technology, one Of these devices a robotic arm that functions like a fishing rod, is controlled remotely to capture small fragments of radioactive debris with a metal claw.
This phase called pilot extraction operation began after a previous attempt was interrupted by technical problems, the objective of removing a small sample of radioactive debris seems simple, but it is much more complex than you can imagine, the operation will last approximately Two weeks is just one small step in a Monumental effort to ensure that Fukushima is safely decommissioned.
The plant houses around 880 tons of highly radioactive material, to put it in perspective that amount is enough to cause devastating impacts if not handled with extreme care, the removal of the debris is one of the biggest challenges in the decommissioning project, A job that will last decades, the robotic arm can extend up to 22 m in length, allowing it to penetrate the reactor and collect less than 3 grams of radioactive material.
It seems little, but given the danger, those 3 grams are of utmost importance for the future stages of dismantling. In preparation for this delicate task, Tepco had already used two mini-drones and a snake-shaped robot that were previously sent to explore the reactors. Technologies are essential to navigate areas where radiation is too intense for any human intervention.
