The Japanese government made an important announcement on Tuesday regarding future actions to limit the consequences of the nuclear environment issues at the Fukushima Dai-ichi plant. These issues began occurring after the 2011 earthquake and tsunami. Japanese officials decided to spend $470 million to make a subterranean ice wall and for some other preventive measures at the Fukushima plant, in the hope to stop leaks of radioactive water on the Pacific ocean.
Through the end of March 2015, an ice wall will be created with the only purpose of freezing the ground to a dept of up to 30 meters using an electrical system to lower and maintain the temperature as cold as minus 40 degrees Celsius. This is not so easy to do and some experts are skeptical about the technology. A second big project will be an upgraded water treatment system to remove the radioactive element tritium which is water-soluble and it’s present in the water because it is used to lower the reactor's temperature.
This is not the final solution to the problems which occurred in Fukushima because it is needed to be covered a 40 year period of continuous action, with long term maintainable projects. At the same time this doesn’t stop immediately the leaks of radioactive water and time has to pass in order to achieve final goals and to have results.
Commentators observed a real interest of the Japanese government to show real action before the
International Olympic Committee will choose, soon, between Tokyo, Istanbul or Madrid as the host of the 2020 Olympics.
