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. Its release marks a milestone for the decommissioning, which is expected to take decades.
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?
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.
Earlier this year, a remote-controlled underwater vehicle successfully collected a tiny sample from inside Unit 1’s reactor — only a spoonful of the melted fuel debris in the three reactors. That’s 10 times the amount of damaged fuel removed at the Three Mile Island cleanup following its 1979 partial core melt.
Matsumoto says “technical difficulty involving the decommissioning is much higher” than the water release and involves higher risks of exposures by plant workers to remove spent fuel or melted fuel.
