This installation will enable robotic removal of spent fuel removal to begin at Fukushima Daiichi Unit 3. Plans to remove this fuel have been complicated by high radiation levels.
To install the cover building’s cylindrical portion workers will have to enter the area to manually bolt the cover to the deck structure.
Installation of the “stopper” by a crane near the spent fuel pool began on January 17 as the first step to construct a new roof for the Unit 3 spent fuel removal. Over the pool some additional structural equipment has also been installed.
Tepco will proceed with the roof construction toward eventual fuel removal with safety as a top priority.
