[1/2] Activists attend a protest against Japan's plan to release treated wastewater from the Fukushima nuclear power plant into the ocean, at the national assembly in Seoul, South Korea, August 24, 2023.
MOLTEN FUEL REMOVALTepco has described the effort to remove highly radioactive fuel debris from reactor cores as an "unprecedented and difficult challenge never attempted anywhere in the world".
That was the worst nuclear plant accident before the 1986 Chornobyl tragedy in Ukraine, then part of the Soviet Union.
About 12.1 trillion yen had been spent on such activities by March 2022, Japan's audit panel, which reviews government expenditures, has said.
That represents an expenditure of more than half of the government's estimate, even before really tough tasks such as fuel debris retrieval have begun, in turns raising concerns about cost overruns.
