Japan throws purified water from Fukushima into the sea | The world

Oh Japan The Fukushima Daiichi nuclear power plant will discharge water into the sea, Once treated, Prime Minister Yoshihide Suka announced on Tuesday (13) (local time). However, the plan Much criticized.

This decision puts an end to seven years of debate over how to dispose of injectables needed to cool rainwater, groundwater, or soluble reactor cores. tsunami of 11 March 2011. 10 years later, remember the Fukushima disaster in the video below.

Suka said the water would be released “after ensuring the presence of clear radioactive material below safety standards”, adding that the government would “take action” to prevent it from damaging the region’s reputation.

Currently, about 1.25 million tons of polluted water is stored in more than 1,000 forts near a nuclear power plant in northeastern Japan. In the fall of 2022, a decision was urgently needed as the water storage capacity limit at that location could be reached.

The water that is pumped into the ocean in this process, which takes two years, has been filtered several times to remove many radioactive substances (radionuclides), but not tritium, which cannot be removed with current techniques.

This option was preferred to others, i.e. by evaporation or constant storage in air. However, fishermen and farmers in Fukushima criticize this, fearing that it will further damage the image of their products among consumers.

“We will take steps to prevent the spread of rumors that are harmful to local agriculture, forestry, fisheries and tourism,” said Tomco Kopayakawa, head of Depok, the operator of the nuclear power plant.

Neighbors are concerned

Japan’s neighbors are also not happy with Tokyo’s complicated relations due to historical conflicts. The China Today he spread his “extreme concern” and asked the Japanese to “be careful” when removing contaminated water. The South Korea Expressed “deep concern” about the Japanese decision.

In early 2020, government-appointed experts recommended going into the sea, which already has active nuclear power plants in Japan and abroad. Experts say tritium is only extremely dangerous to human health. The International Atomic Energy Agency also supports this option.

The ecosystem Greenpeace asks that water be stored until technology allows it to be completely purified.
