8/8/2023 0 Comments Japan reactor meltdown 2012Removing the fuel in the cooling pools was delayed more than four years by mishaps, high radiation and radioactive debris from an explosion that occurred at the time of the reactor meltdowns, underscoring the difficulties that remain. Removing fuel units from the cooling pools comes ahead of the real challenge of removing melted fuel from inside the reactors, but details of how that might be done are still largely unknown. Study links Fukushima disaster to rise in infant heart surgeries.TEPCO says the removal at Unit 3 will take two years, followed by the two other reactors, where about 1,000 fuel units remain in the storage pools. Satellite image on 16 March 2011 of the four damaged reactor buildings. Others, though, reserve that term for times when nuclear fuel melts through a reactors innermost. Fukushima Daiichi nuclear disaster casualties. The fuel units in the pool located high up in reactor buildings are intact despite the disaster, but the pools are not enclosed, so removing the units to safer ground is crucial to avoid disaster in case of another major earthquake similar to the one that caused the 2011 tsunami. This ended on May 5, 2012, when the country’s last operating reactor, in Hokkaido, shut down for inspection, leaving Japan without nuclear power for the first time in more than 45 years. Some experts would consider the apparent melting of the fuel rods to be a partial meltdown. FILE - The Fukushima Daiichi nuclear power plant sits in coastal towns of both Okuma and Futaba, as seen from the Ukedo fishing port in Namie town, northeastern Japan, on March 2, 2022. Only two of Japans nuclear reactors were still running by March 2012. said workers started removing the first of 566 used and unused fuel units stored in the pool at Unit 3. with nuclear meltdowns (overheating and damage to the reactor core, with melting. On 11 March 2011, a nuclear accident occurred at the Fukushima Daiichi Nuclear Power Plant in kuma, Fukushima, Japan. Tokyo - The operator of the tsunami-wrecked Fukushima nuclear plant began removing fuel Monday from a cooling pool at one of three reactors that melted down in the 2011 disaster, a milestone in what will be a decades-long process to decommission the facility.
