NHK, Feb. 24, 2014: Japan’s nuclear regulators have criticized the operator of the crippled Fukushima Daiichi nuclear power plant for failing to prevent massive leakage of highly radioactive water. [Tepco] announced last Thursday that 100 tons of water containing record high levels of radioactive substances had overflowed from a storage tank near the No. 4 reactor building.
CNN, Feb. 24, 2014: [...] an estimated 100 metric tons of highly contaminated water flowed over a barrier around a containment tank and is being absorbed into the ground, [TEPCO] said in a statement [...] The leak reported Thursday is one of the largest since TEPCO reported last summer that about 300 tons of radioactive water had leaked from a tank.
Takafumi Anegawa, Tepco: “You may feel that we didn’t do enough, but now we know what the problem is, so we’d like to take control of our safety system as much as possible.”
Commissioner Toyoshi Fuketa, Nuclear Regulation Authority of Japan: “The safety system was supposed to prevent such accidents. But it failed. It’s a very serious problem.”
Reuters, Feb. 13, 2014: Tepco “was taken over by the government in 2012”
Center for Marine and Environmental Radiation, Woods Hole Oceanographic Institution, Feb. 20, 2014: [...] Note- Leak = 12 TBq [12 trillion becquerels of] 90Sr per calc. by K. Buesseler today.
2013 study co-authored by Buesseler: “The total amount of 90Sr released [since start of Fukushima disaster] could range from 90 to 900 TBq”
