    The facility was severely damaged in March 2011, after a 9.0-magnitude earthquake in the Pacific Ocean caused a massive tsunami that hit the plant, resulting in the meltdown of three nuclear reactors. High radiation levels forced some 160,000 people to evacuate from Fukushima Prefecture.

    A Japanese Nuclear Regulation Authority (NRA) study has detected deadly levels of radiation near the fifth floor of the reactor buildings of Units 2 and 3 at the Fukushima NPP, Yomiuri Shimbun reported on Wednesday.

    According to the interim report, the lids on top of the second and third reactor containment vessels are contaminated with high levels of radioactive Caesium 137. According to the NRA, the radiation levels near the lids could reach up to 10 Sieverts p.h. - which can be fatal for a person who has spent just one hour there.

    Originally, Tokyo had planned to start removing melted fuel debris from Unit 2, the first of three reactors, later in 2021 - 10 years after the catastrophe. However, in December 2020, plant operator Tokyo Electric Power Co. and the Japanese government announced a delay until 2022, as the development of robots for debris removal was held back by the pandemic.

    At the same time, NRA Chairman Toyoshi Fuketa called the reports "extremely serious", stressing that they would make melted fuel removal "more difficult".
