21 February 2012, Tokyo Electric Power Company (TEPCo) announced they will start pouring concrete! (again?)

They will focus on the floor of the Pacific Ocean, near the water intakes of the Fukushima Daiichi nuclear plant, to prevent any further radioactive materials from spreading.

TEPCo says they will begin right away (finally), starting on 22 February.  They will cover a 70,000 square meter (22,9658.7 square feet) area!

TEPCo hopes that the 60 centimeter (nearly 2 feet) thick layer of concrete will stop the spread of radioactive mud and sand, for at least 50 years!  The job could take four months.  The decision was made because high levels of cesium are still being detected in the Pacific Ocean!

People still need to demand an explanation why this decision took so long.  And what about the rest of the nuclear plant?

How did the Soviets deal with Chernobyl?
