TEPCO, the company in charge of the damaged Fukushima nuclear power plant, cannot filter a dangerous radioactive isotope out of about 400,000 metric tons of water before returning it to the sea, and has contracted with a US company for a second system.
In April, Tokyo Electric Power Company (TEPCO) launched a contaminated water management system at the crippled Fukushima nuclear plant, which was designed to pump groundwater into tanks before it passes through the premises of the plant. After checking the water’s quality it would be dumped into the ocean.
