TEPCO, the operator of the Fukushima nuclear plant that was destroyed by the March tsunami, is planning to cover no. 1, 3 and 4 reactors with polyester sheets to prevent additional dispersal of toxic substances.
Experts fear that during the rainy season the rainwater may become contaminated.
The first building to be isolated is the no. 1 reactor. The covering will begin later this month and will be carried through by using 62 pieces of one-millimeter thick polyester. The company hopes to finish the operation by the end of September and then continue with no. 3 and 4 reactors.
To minimize human exposure, TEPCO will use a large crane to assemble together the polyester sheets. [NHK World]
