An extendable robotic started on Tuesday a two-week mission to retrieve the primary pattern of melted gas particles from inside one in all three broken reactors on the Fukushima Daiichi nuclear energy plant.
Extremely radioactive fuel and different supplies within the reactors melted when a massive earthquake and tsunami in 2011 broken the plant’s cooling techniques.
The plant’s operator, Tokyo Electrical Energy Firm Holdings, has beforehand used small robots to look at the within of the reactors, however that is the primary time for it to gather a pattern of the melted particles in what is going to mark the beginning of essentially the most difficult a part of the plant’s decadeslong decommissioning.
The mission was initially scheduled to start on Aug. 22 however was suspended when staff observed that 5 1.5-meter (5-foot) pipes for use to push the robot into the reactor had been organized within the incorrect order, TEPCO stated.
The tools was reassembled in the correct order for Tuesday’s try, the corporate stated.
As soon as contained in the reactor vesselthe robotic is operated remotely from a safer location.
The robotic, nicknamed “telesco,” can prolong as much as about 22 meters (72 ft), together with the pipes pushing it from behind, to achieve the melted gas mound, the place it can use tongs to gather a fraction measuring lower than 3 grams (0.1 ounce). It’s anticipated to take about two weeks to acquire the fragment.

An estimated 880 tons of fatally radioactive molten gas stays within the three reactors.
Chief authorities spokesperson Yoshimasa Hayashi famous that the mission marked the beginning of essentially the most troublesome section of the Fukushima Daiichi cleanup. “The government will firmly and responsibly tackle the decommissioning until the very end,” he stated.
The federal government and TEPCO have set a 30- to 40-year goal for the cleanup, regardless of criticism it’s unrealistic. No particular plans for the total elimination of the melted gas particles or its storage have been determined.
