The Japanese authorities will undertake on Tuesday the final phase for the construction of an underground ice wall around the Fukushima No.1 nuclear-powered plant to prevent water pollution with radioactive substances.

The one-and-a-half-mile ice barrier is considered a key step in scaling down the accumulation of contaminated water in the nuclear plant.
There is concern, however, that underground contaminated water may leak out, owing to differences in water levels inside and outside the reactors.
On the other hand, the Japan's Nuclear Regulatory Authority stated that the security measures are set, and new assignments have been authorized.
Once completed, the ice wall should diminish the groundwater flow from 140 tonnes per day to less than 100. ■
