Via NHK News, excerpt :
" One month after the Fukushima Daiichi nuclear plant was crippled by the quake and tsunami that devastated Japan's northeastern coast, the plant's operator is still struggling to regain control.
Tokyo Electric Power Company has been striving to restore reactor cooling systems since the March 11th disaster knocked out electricity at the plant. The power station continues to release radioactive substances into the air and sea.
Heavily contaminated water in turbine buildings and a concrete tunnel has been hampering restoration efforts and preventing workers from even inspecting the pumping systems."
