OKUMA, Japan — The operator of the tsunami-wrecked Fukushima Daiichi nuclear energy plant says it has begun releasing its first batch of handled radioactive water into the Pacific Ocean.
In a stay video from a management room on the plant Thursday, Tokyo Electrical Energy Firm Holdings confirmed a workers member activate a seawater pump, marking the start of the controversial venture that’s anticipated to final for many years.
“Seawater pump A activated,” the primary operator stated, confirming the discharge was underway.
Japanese fisher teams have opposed the plan out of fear of additional harm to the popularity of their seafood. Teams in China and South Korea have additionally raised concern, making it a political and diplomatic concern.
However the Japanese authorities and TEPCO say the water should be launched to make room for the plant’s decommissioning and to forestall unintended leaks. They are saying the remedy and dilution will make the wastewater safer than worldwide requirements and its environmental influence can be negligibly small. However some scientists say long-term influence of the low-dose radioactivity that is still within the water wants consideration.
The water launch begins greater than 12 years after the March 2011 nuclear meltdowns, attributable to an enormous earthquake and tsunami. It marks a milestone for the plant’s battle with an ever-growing radioactive water stockpile that TEPCO and the federal government say have hampered the daunting process of eradicating the fatally poisonous melted particles from the reactors.
The pump activated Thursday afternoon would ship the primary batch of the diluted, handled water from a mixing pool to a secondary pool, the place the water is then discharged into the ocean by an undersea tunnel. The water is collected and partly recycled as cooling water after remedy, with the remaining saved in round 1,000 tanks, that are already crammed to 98% of their 1.37-million-ton capability.
These tanks, which cowl a lot of the plant advanced, should be freed as much as construct the brand new amenities wanted for the decommissioning course of, officers stated.
Prime Minister Fumio Kishida stated it’s indispensable and and can’t be postponed. He famous an experimental removing of a small quantity of the melted particles from the No. 2 reactor is about for later this yr utilizing a remote-controlled big robotic arm.
TEPCO govt Junichi Matsumoto stated Thursday’s launch was to start with the least radioactive water to make sure security.
Ultimate preparation for the discharge started Tuesday, when only one ton of handled water was despatched from a tank for dilution with 1,200 tons of seawater, and the combination was stored within the main pool for 2 days for last sampling to make sure security, Matsumoto stated. A batch of 460 tons was to be despatched to the blending pool Thursday for the precise discharge.
However Fukushima’s fisheries, tourism and economic system — that are nonetheless recovering from the catastrophe — fear the discharge may very well be the start of a brand new hardship.
Fukushima’s present fish catch is just about one-fifth its pre-disaster degree, partly on account of a decline within the fishing inhabitants. China has tightened radiation testing on Japanese merchandise from Fukushima and 9 different prefectures, halting exports at customs for weeks, Fisheries Company officers stated.
