TOKYO Kyodo–Tokyo Electric Co. continued efforts Sunday to restore power and enhance cooling efficiency at the crisis-hit Fukushima Daiichi nuclear plant as it prepared to turn on the lights in the control room for the plants No. 4 reactor and inject fresh water into four reactors.The utility, known as TEPCO, will inject fresh water into pools storing the spent nuclear fuel at the plants No. 1, 2, 3 and 4 reactors to prevent crystallized salt from seawater already injected from hampering the smooth circulation of water and thus diminishing the cooling effect.The company continued with the work to remove a pool of water containing highly concentrated radioactive substances that was detected in the turbine buildings of the No. 1 reactor at the plant in Fukushima Prefecture, around 220 kilometers northeast of Tokyo.

And from the Japanese edition of Nikkei:



(My translation: According to the Economy, Trade & Industry Ministry’s Nuclear and Industrial Safety Agency (NISA), the water which has collected in the turbine building of the No. 2 reactor at Fukushima’s Dai-ichi nuclear power station registered more than 1000 mSv/hr. This is 10 times the normal safety limit of 100 mSv.

“This is clearly from a nuclear fission reaction and is possibly coming from the reactor”, NISA stated, adding, “we don’t know whether it is originating from the reactor or from the spent-fuel pool. We are analyzing the contents.”)
