• From Kyodo News: Woes deepen over radioactive water at nuke plant, sea contamination

Japan on Sunday faced an increasing challenge of removing highly radioactive water found inside buildings near some troubled nuclear reactors at the Fukushima Daiichi plant, with the radiation level of the surface of the pool in the basement of the No. 2 reactor's turbine building found to be more than 1,000 millisieverts per hour.

... efforts to restore power and enhance cooling efficiency at the crisis-hit nuclear power plant is showing slow progress partly due to the radioactive pools of water found at the Nos. 1, 2, 3 and 4 units.

Workers there are planning to turn on the lights in the control room of the No. 4 reactor, while also trying to inject freshwater into tanks storing spent nuclear fuel at the plant's Nos. 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.
