TOKYO - One of four heavily damaged reactor buildings at Japan's tsunami-battered Fukushima nuclear power plant has been cleared of radioactive fuel rods, the operator said Saturday.
It was a significant step in the decommissioning efforts, but workers still have three heavily crippled reactors to clean up after they were sent into meltdown in the 2011 quake-tsunami disaster. The overall cleanup work of the Fukushima plant is expected to take decades.
A total of 1,535 fuel rod assemblies have been now taken out of the building after Tokyo Electric Power Co.'s (TEPCO's) yearlong operation, a company spokesman said.
"Completion of the removal work is a milestone, but the decommission work will continue," plant chief Akira Ono told reporters.
The nuclear fuel was removed from a pool used to store the rods -- which were mostly spent -- in the reactor number 4 building, which was offline for regular checkups at the time of the March 2011 disaster.
The tsunami battered the plant's cooling system and sent reactors number 1 to 3 into meltdown, setting off the worst atomic accident in a generation.
TEPCO will remove fuel rod assemblies from the pools of other damaged buildings before extracting the melted fuel from the reactors.
