Tuesday marked the 2nd day of nuclear fuel removal from a damaged reactor building at the Fukushima Daiichi nuclear power plant.
The storage pool at the Number 4 reactor building holds 1,533 units of nuclear fuel. 1,331 of them are highly radioactive spent fuel and the rest are unused.
It took workers about 3-and-a-half hours to transfer 4 units of unused fuel into a special fuel transport container placed into the pool.
Tokyo Electric Power Company officials say the units are being hoisted slowly from their racks to avoid small bits of debris.
It says underwater cameras monitor the process when the fuel units are placed in the container.
