Extremely high radiation detected inside the Fukushima nuclear power plant reactor

Tokyo Electric Power Company (TEPCO) of Japan announced on April 23 the results of an internal investigation into Reactor Unit 2 at the Fukushima Daiichi Nuclear Power Plant. Data shows that the radiation dose in the relevant area is extremely high, and it has also confirmed that nuclear fuel debris still remains inside the reactor. This is the first time since the 2011 Fukushima nuclear power plant accident that TEPCO has conducted internal measurements of nuclear radiation in a reactor core that has suffered core meltdown. According to NHK (Japan Broadcasting Corporation), TEPCO’s investigation was carried out on April 16 by inserting an optical-fiber endoscope equipped with measuring instruments into the reactor interior through a pipe. At a location about 5 meters from the bottom of the reactor, the measured nuclear radiation dose was approximately 4.7 sieverts per hour, which is categorized as an “extremely high” level.
