Japan’s plan to release treated radioactive water from the Fukushima nuclear plant into the Pacific Ocean can have “zero environmental influence,” in accordance to one professor who spoke to CNBC.

Japan mentioned Tuesday the Fukushima plant’s operator, Tokyo Electric Power Co or TEPCO, will deal with and dilute the water earlier than pumping it out in about two years. There are greater than 1,000,000 metric tons of radioactive water from the wrecked plant, and it’ll take a long time to fully launch them.

The transfer has drawn sharp opposition from Japan’s neighbors and environmental activists.

But Brent Heuser of the University of Illinois mentioned the filtering course of will take away most radioactive components from the water, leaving solely tritium — a radioactive isotope of hydrogen — that is not dangerous in small portions.   

“Tritium is not dangerous in small quantities … it is gonna be very dilute, it is merely not a priority, the environmental influence is zero,” Heuser, a professor of nuclear, plasma and radiological engineering, advised CNBC’s “Squawk Box Asia” on Thursday.

Still, Japan’s neighbors together with China and South Korea have opposed the plan. Environmental group Greenpeace in addition to native residents and fishermen additionally raised their issues.

South Korea summoned the Japanese ambassador in Seoul and is reportedly exploring methods to fight Japan’s decision in an international court.

Over in China, the overseas ministry criticized Japan in a statement for “unilaterally” deciding to launch the water, whereas ministry spokesman Zhao Lijian challenged Japanese officers to drink water from the Fukushima plant.

Meanwhile, Reuters reported Taiwan saying it’ll proceed to categorical its issues and intently monitor the associated developments.

The International Atomic Energy Agency mentioned “Japan’s chosen water disposal technique is each technically possible and in line with worldwide apply.” The U.S. said Japan has been transparent and its method seems in line with “globally accepted nuclear security requirements.”

For Heuser, there are bigger points about ocean air pollution to fear about than Japan releasing the handled water.

“I’d say to people who find themselves involved about this going into the ocean: We dump eight tons of plastics in the ocean, pregnant ladies are not supposed to eat tuna due to mercury poisoning, microplastic is in the marine meals chain — this is what we needs to be frightened about,” he mentioned.
