(10,440 posts)Fukushima operator TEPCO is getting ready for its toughest and the most dangerous clean-up operation. In November it will try to remove 400 tons of spent fuel from plants Reactor No. 4. But even a little mistake may result in a new nuclear disaster.
The operation is scheduled to start in the beginning of November and be completed by around the end of 2014.
Under normal circumstances, the operation to remove all the fuel would take about 100 days. TEPCO (Tokyo Electric Power Co) initially planned to take two years, but reduced the schedule to one year in recognition of the urgency, as even a minor earthquake could trigger an uncontrolled fuel leak.
During this period TEPCO plans to carefully remove more than 1,300 used fuel rod assemblies, packing radiation 14,000 times the equivalent of the Hiroshima nuclear bomb, from their cooling pool.
The base of the pool where the fuel assemblies are situated is 18 meters above ground and the rods are 7 meters under the surface of the water.
TEPCOs first task is to remove the debris from the Reactor No. 4 fuel pool.
