TEPCO released plans for workers to begin preparations for more intensive work at the Number 4 reactor. Experts around the world have warned of the extremely compromised state of the damaged building that holds over 1,500 fuel rods.
As reported last week, TEPCO will begin attaching a special crane to take the fuel out of the pool and constructing a cover to prevent the spread of radioactive materials from the building. The cover will be 31 meters long and 69 meters wide and 53 meters high.
At Reactor 1 the cover was constructed to enclose the entire reactor building, however at Reactor 4, the structure will cover only the upper part of the pool for the reactor.
The cover is expected to be completed by autumn next year. Spent nuclear fuel will then be removed from the pool and stored on the plant compound.
