About 7,000 people work here, building new water storage tanks, moving radioactive debris to a new disposal site, and erecting enormous scaffoldings over reactor buildings torn apart by the huge hydrogen explosions that occurred during the accident.Īccess to the plant is easier than it was just a year ago, when visitors still had to change into special protective clothing. Tepco is keen to portray the plant as one big industrial cleanup site. “Now that we have seen it, we can make plans to retrieve it.” “Until now, we didn’t know exactly where the fuel was, or what it looked like,” said Takahiro Kimoto, a general manager in the nuclear power division of the plant’s operator, Tokyo Electric Power Co., or Tepco. Six and a half years after the accident spewed radiation over northern Japan, and at one point seemed to endanger Tokyo, the officials hope to persuade a skeptical world that the plant has moved out of post-disaster crisis mode and into something much less threatening: cleanup. Now that engineers say they have found the fuel, officials of the government and the utility that runs the plant hope to sway public opinion. Scientists and engineers built radiation-resistant robots like the Manbo and a device like a huge X-ray machine that uses exotic space particles called muons to see the reactors’ innards. With radiation levels so high, the fate of the fuel remained unknown.Īs officials became more confident about managing the disaster, they began a search for the missing fuel. No one knew for sure exactly how far those molten fuel cores had traveled before desperate plant workers - later celebrated as the “Fukushima Fifty” - were able to cool them again by pumping water into the reactor buildings.
