For the wrecked Fukushima Daiichi nuclear plant, managing the ever-growing volume of radioactive wastewater held in more than 1,000 tanks has been a safety risk and a burden since the meltdown in March 2011.
FILE - The Fukushima Daiichi nuclear power plant, damaged by a massive March 11, 2011, earthquake and tsunami, is seen from the nearby Ukedo fishing port in Namie town, northeastern Japan, Thursday, Aug. 24, 2023. For the wrecked Fukushima Daiichi nuclear plant, managing the ever-growing radioactive water held in more than 1,000 tanks has been a safety risk and a burden since the meltdown in March 2011.
But it's just the beginning of the challenges ahead, such as the removal of the fatally radioactive melted fuel debris that remains in the three damaged reactors, a daunting task if ever accomplished.WHAT HAPPENED AT FUKUSHIMA DAIICHI?that destroyed the plant’s power supply and cooling systems, causing three reactors to melt and spew large amounts of radiation.
The pace will later pick up, and about 1/3 of the tanks will be removed over the next 10 years, freeing up space for the plant's decommissioning, said TEPCO executive Junichi Matsumoto, who is in charge of the treated water release. He says the water would be released gradually over the span of 30 years, but as long as the melted fuel stays in the reactors, it requires cooling water, which creates more wastewater.
Emptied tanks also need to be scrapped for storage. Highly radioactive sludge, a byproduct of filtering at the treatment machine, also is a concern.About 880 tons of fatally radioactive melted nuclear fuel remain inside the reactors. Robotic probes have provided some information but the status of the melted debris remains largely unknown.
