The radioactive water accident at the Fukushima nuclear power plant occurred on March 11, 2011, after a 9.0 earthquake Richter
Japan is studying the possibility of dumping 1 million tons of radioactive water from the rugged Fukushima nuclear power plant to the Pacific Ocean , because in three years there will be no space to store it.
“The only option will be to pour the water into the sea and dilute it,” Japanese Environment Minister Yoshiaki Harada told a news conference on Tuesday .
The accident at the Fukushima nuclear power plant occurred on March 11, 2011, after an earthquake of 9.0 Richter and the subsequent tsunami on the northeast coast of Japan.
Harada said that once treated, the water used to cool the reactor cores of the Fukushima plant, which collapsed after the earthquake and tsunami, could be dumped into the Pacific Ocean, according to reports from the Kyodo news agency.
Even after being treated, the water is still contaminated with tritium, a hydrogen isotope that is difficult to separate and considered by the government as relatively harmless to humans, the official added.
The Tokyo Electric Company (Tepco), which owns the nuclear power plant, has accumulated more than one million tons of radioactive water since the accident, but has noted that the space in the tanks in which it stores the liquid runs out and by 2022 He will have no more.
For this reason, Tepco studies the possibility of the sea and together with the government discuss that option.
The contaminated water is subjected to a treatment to eliminate all radioactive isotopes, except for tritium, and then it is crenellated in tanks. Tritium is not considered dangerous for human health below the permitted levels, which vary between different countries.
In Japan, the permitted level is below 1,500 becquereles per liter, even Tepco has discharged hundreds of tons of processed water, between 300 and 600 becquereles.
