An attempt to use an extendable robot to remove a fragment of melted fuel from Fukushima Daiichi’s Unit 2 reactor was suspended due to a technical issue. Workers found that five pipes used to maneuver the robot were placed incorrectly and couldn’t be fixed within the radiation exposure time limit. The robot, which can extend up to 22 meters, was to collect a fuel fragment, marking the start of the challenging fuel debris removal phase. The mission’s new start date is undecided, according to Tokyo Electric Power Company Holdings.
