Electric power company of Tokyo has announced another correction in regards to groundwater radiation at the Fukushima No. 1 nuclear complex. The power company said that, at the moment, it is only a tenth of what was announced earlier in June 2013. The correction was made on June 12, 2013, which was the second one that the utility has issued for groundwater data.


Tepco is now looking into a battle with water and is desperately seeking the consent from the fishermen in order to divert or dump the least-tainted parts of it into the Pacific Ocean. This will prevent it from mixing with extremely radioactive water which accumulates in the reactor buildings. When the tainted water runs out of designated storage space it then floods both the premises and the environment.

When something like this happens, it makes the decommissioning process very difficult. In May 2013, the company said that the level of radioactive cesium in a sample of Fukushima No. 1 groundwater was so low that it could not be detected. However, on June 3, 2013, the company said that the sample contained 0.61 becquerel per liter.

The water was then reversed on Wednesday, June 12, 2013, to a maximum of 0.055 becquerel. Any other radioactive substances in the water were not mentioned by the utility. With this latest correction, it can become difficult for Tepco to dump water further.
