"Radioactive water keeps workers out"
"Turbine room floods linked to sea"
"Reactor turbine basements flooded with highly radioactive materials kept a desperate effort to stabilize the Fukushima No. 1 power plant at bay Monday, as fresh data showed that nearby seawater was being contaminated further by the lesking facility."
Effforts by TEPCO to restore the cooling systems for reactors 1 through 4, as well as their spent-fuel storage pools, continue to be halted by the radioactive water which is now at lethal levels.

Trenches below the turbine buildings have radiation as strong as 1,000 millisieverts/hour- the same as in the turbine buildings.
Since the trenches exits are only about 55 to 70 meters from the sea, TEPCO officials are worried that the highly poluted water could overflow from the trenches and out to the sea.

A board member of Citizens' Nuclear Information Center said it may tale even a month to pump out the toxic water, restore damaged cooling facilities and bring the reactors under control to end the crisis.
Eventually the plant may need to be encased in concrete, like Chernobyl was, he said.

Prof, Furukawa, Nagoya Univ., emeritus on nuclear energy, said workers can probably work only up to ten minutes at a time.
"Although water in the no. 1 turbine has been pumped into a container tank, TEPCO has not yet come up with ways to remove the flooding at the other three turbine buildings. "
"Having been unable to find effective ways to move forward, TEPCO seems to be visibly confused by the situation and has botched some of its announcements of crucial monitoring data."
