Tokyo Electric Power Co. (TEPCO) said workers have removed 10 percent of the fuel assemblies from Unit 4 at the Fukushima Daiichi nuclear power plant.
TEPCO said on its website that it has transferred 198 of 1,533 fuel assemblies from the spent fuel pool to a common pool as of Jan. 20. Of those, 176 are spent fuel assemblies and 22 are new fuel.
The transfer started on November 18, 2013 and is expected to be completed at the end of 2014. The fuel assembly transfer is the first step in decommissioning Unit 4, which was damaged by hydrogen explosions and fire during the 2011 disaster.
