Decontamination of water in Fukushima, a priority

The 110 000 tons of radioactive water that flooded the plant currently rugged Fukushima must absolutely be decontaminated, otherwise flow into the sea by one week. Tokyo Electric Power (TEPCO) has tested a facility to help decontaminate the water used to cool reactor damaged by the earthquake and tsunami of March 11.

A last-minute obstacle appeared Thursday. A leak was detected in a vessel used to absorb cesium. The equipment must be replaced and TEPCO hopes to start the decontamination process by Friday night. If the system does not work, the plant could be running out of space from June 20 to contain the radioactive water that may well flow into the Pacific Ocean.

Despite these obstacles, Tepco should not change its schedule, which provides to arrive at the "cold shutdown" of the three reactors in Fukushima damaged in January 2012 - stop the boiling process fuel rods in order to begin cleaning site, which could take more than a decade.
