The "Suzuran", one of the world's largest liquid radioactive waste treatment plants, treats radioactive liquid with chemicals and stores it in a cement form. It is can process 35 cubic metres of liquid waste a day and 7,000 cubic metres a year.
Engineers also plan to build two giant "silt curtains" made of polyester fabric in the sea to block the spread of more contamination from the plant.
TEPCO has start releasing 11,500 tonnes of low-level radioactive seawater that had been used to cool overheated fuel rods after it ran out of storage capacity for more highly contaminated water.
