Tokyo Electric Power Co. has announced a plan to cover the seabed adjacent to the Fukushima No. 1 nuclear power plant with a coating material composed of clay and cement as a new measure to prevent the spread of soil contaminated with radioactive substances.
According to TEPCO's announcement on Tuesday, the coating material will be placed in areas surrounded by breakwaters and silt fences that had already been installed. The work of laying the coating material on the seabed is set to be started later this month and completed in three to four months.
The coating material, which will be about 60 centimeters thick, will cover areas stretching along a total of 900 meters of shoreline to a distance of 80 meters out. The 72,000-square-meter area is equivalent to 5.5 times the field area of Tokyo Dome. (Yomiuri)
