#Fukushima I Nuke Plant: Reactors 2, 4 Also Have Water Puddles

So the Reactors 1, 2, 3 and 4 all have leaks from the pipes and/or valves that connect to the Containment Vessels/Reactor Pressure Vessels. Water from the Reactor 1, 2, 3 are proven highly radioactive, and it is probably the same for the Reactor 4.

Yomiuri Shinbun (in Japanese; 11:18AM JST 3/26/2011) reports:

TEPCO announced on March 26 that there was a water puddle in the Reactor No.2 [turbine building], and it was highly radioactive, just like in the Reactors 1 and 3. TEPCO also found water in the Reactor 4 [turbine building]. The locations where the water puddles were found are where the workers have been trying to lay power cables in order to restore the cooling systems.

In other words, the water puddles were found in the turbine building basements, right underneath the pipes and valves coming from the Reactor Containment Vessels.

This illustration is from Asahi Shinbun (3:01AM JST 3/26/2011). It is the illustration of the Reactor 3, but it is practically the same with other Reactors. The red dot at the center bottom is where the workers got irradiated. The left structure is the Reactor building, the lower, right structure is the turbine building.

A bit more details from Asahi Shinbun about the depth of the radioactive water. It's not "puddles" any more, though TEPCO and the government have been calling it "puddle". They should have called it for what it is, a flood:

Maximum depth of radioactive water in each reactor:

Reactor 1: 40 centimeters (1.3 feet)

Reactor 2: 1 meter (3.28 feet)

Reactor 3: 1.5 meters (4.92 feet)

Reactor 4: 80 centimeters (2.62 feet)
