#Fukushima I Nuke Plant: 1,000 Milli-Sievert Water Flowing into Ocean from Reactor 2's Water Intake

(4/2/11 I have an update on this news, here. Alas, concrete fill failed. Anyone surprised?)

From Yomiuri Shinbun (2:52PM JST 4/2/2011):


Tokyo Electric (TEPCO) announced that it was confirmed at about 9:30AM that the water containing high level of radioactive materials was flowing out into the ocean from near the water intake for the Reactor 2 at Fukushima I Nuclear Power plant.


Contamination of the seawater near the plant has continued but the source of contamination hadn't been identified till today.


The identified source was a 2-meter deep concrete shaft near the water intake for the Reactor 2. It was created for the inspection of power cables, but water 10 to 20-centimeter deep was found at the bottom of the shaft at about 9:30AM. The radiation level of the water was measured at 1,000 milli-sievert. There is a 20-centimeter crack on the side of the shaft, and the contaminated water is leaking through the crack into the ocean.


TEPCO plans to fill the shaft with concrete to stop the leak into the ocean.

Question: Where does that water come from?
