The cylindrical base supporting the reactor of Unit 1 of the Fukushima Daiichi Nuclear Power Station, which caused the meltdown, has been revealed to have broken almost the entire circumference. TEPCO has stated that even if the pedestal can no longer support the reactor, it will not collapse significantly due to being held back by surrounding structures.
The NRA has requested an immediate response, saying that it is necessary to assume the worst-case scenario, based on the fact that there are still many areas where the situation has not been grasped.
