The Minister of Nature Protection of Japan Yoshiaki Harada at the last briefing announced an important date - the summer of 2022. By this time, there will be no free space for containers with contaminated water on the territory of the Fukushima NPP. There are already more than 1000 of them, a thousand tons each, and water from underground sources is still coming. There is exactly one way out - to drain radioactive waste and hope that the vast Pacific Ocean will "neutralize" them.
The Japanese authorities insist that they have studied all the methods of water purification and have not found another solution. In 2013, cesium was extracted from the contaminated water using volcanic zeolite rock, then filtered from strontium, but faced with the problem of tritium. It dissolves too easily in water, and today there are simply no technologies capable of neutralizing such an amount of irradiated liquid.
Critics, represented by the Greenpeace organization, immediately clarified that the technologies are there, but they are not cheap. For example, the promising Kurion plant, which costs $ 1 billion and requires several hundred million dollars a year to operate. However, given the available volumes of radioactive water, this may indeed be economically unprofitable. Then it is cheaper and easier to build thousands of concrete sarcophagus pools throughout the 30-km exclusion zone, but this is not an option either.
What will happen to the oceanic environment if such a quantity of radioactive materials gets into it, no one undertakes to calculate, but the global damage will be astronomical.
