Tokyo Electric Power (TEPCO) said that treatment of the water had removed all radioactive elements except tritium. which according to experts is safe in small amounts.
The main function of the Fukushima-1 treatment plant is to filter large quantities of tritium in the water.
According to a TEPCO report. the water still holds other elements. including radioactive iodine. cesium and strontium.
Some dangerous radioactive isotopes are not captured by the special water purification system installed at the Fukushima-1 power station. according to the Japan Times.
TEPCO general manager Junichi Matsumoto stressed that radioactive elements still remained. mainly earlier in the crisis when workers had to deal with huge amounts of polluted water.
`We had to prioritize processing large amounts of water as quickly as possible to reduce the overall risk.` Matsumoto said.
Around 161.000 tons of treated water has 10 to 100 times the limit for release into the sea. according to TEPCO.
According to the Tokyo Electric Power. as of August 2018. approximately 680 containers inside NPP have accumulated about 920.000 tons of water containing tritium.
In March 2011. the Fukushima Daiichi nuclear plant was hit by a 46-foot tsunami triggered by a 9.0-magnitude offshore earthquake. crippling the facility`s cooling system and resulting in the leakage of radioactive materials. hydrogen-air explosions and eventually the plant`s shutdown.
