Fukushima Daiichi: A source of radioactivity leaking into ocean identified

NHK reports that TEPCO said on Saturday that water has been seeping from a crack in the wall of a 2-meter deep pit that contains power cables near the Unit 2 reactor’s water intake.  Water measuring between 10 and 20 centimeters deep was found in the pit. The radiation level has been measured at over 1,000 mSv/hr. This is extremely high, and exposure for even a short period would be dangerous.  NISA says the crack could be one of the sources of radioactivity contributing to the high levels found in seawater near the water outlet (reported here and here).

TEPCO says it is preparing to pour concrete into the cracked pit to stop the radioactive water leak.

There is still no information of how the radioactive water is escaping from the Unit 2 containment vessel.
