Japan begins pumping Fukushima nuclear plant water into sea

Japan has begun to pump more than a million metric tons of treated water from the destroyed Fukushima-Daiichi nuclear power plant. The process is expected to take decades to complete.

Japan began the release of wastewater from the Fukushima nuclear plant on Thursday, facility operator TEPCO said.

The process of pumping treated water into the Pacific Ocean through a special kilometer-long tunnel was started despite opposition from fishermen, environmentalists and China.

An earthquake and tsunami caused core meltdowns at the plant in 2011. Since then, the shut-down reactors have had to be cooled with water that was then stored in tanks.

However, according to TEPCO, capacity is running out.
What else do we know?

The site has been collecting some 100,000 liters (26,500 gallons) of water every day. Around 1.34 million metric tons are now being stored there.

The water is contaminated not only from cooling the damaged reactors, but also with the seepage of groundwater and rain.

Japan has said that it will discharge at most 500,000 liters per day, with the release of the water planned to take some 30 years to complete.

Thursday's discharge, which authorities say is on a small scale, is scheduled to be followed by three more between now and March 31.

The International Atomic Energy Agency (IAEA) has said the release of the water is safe.

The Japanese government and TEPCO say the release is necessary to make room for the plant's decommissioning and to prevent accidental leaks.

Japan has said almost all radioactive elements from the water have been filtered out before its release.

The only exception is tritium, which is difficult to filter. But many nuclear experts say tritium poses little risk to human health, as it does not accumulate in the body.

"Nuclear power plants worldwide have routinely discharged water containing tritium for over 60 years without harm to people or the environment, most at higher levels than the 22 TBq per year planned for Fukushima," Tony Irwin, an honorary associate professor at the Australian National University, said in a note cited by Reuters news agency.

Chinese criticism

China, which has staunchly opposed the release of the wastewater from the start, has slammed Japan for beginning with the discharge.

"The ocean is the common property of all humanity, and forcibly starting the discharge of Fukushima's nuclear wastewater into the ocean is an extremely selfish and irresponsible act that ignores international public interests," the Foreign Ministry said in a statement.

It said Tokyo had failed to prove that its wastewater purification was reliable in the long term and to give sufficient evidence to support its contention that the discharge was harmless.

Beijing has banned food imports from 10 Japanese prefectures, with Hong Kong following suit.

South Korea said in a statement released Tuesday that it did not necessarily approve the wastewater release plan but that the scientific and technical basis for it appeared to be in order.

Japan: Fukushima water release puts Kishida under pressure

Prime Minister Fumio Kishida's government is facing a wave of criticism at home and abroad after allowing the release of treated radioactive water from Fukushima into the Pacific Ocean.

To a chorus of criticism at home and abroad, Japan on Thursday started to release treated radioactive water from the Fukushima Dai-Ichi nuclear plant into the Pacific Ocean.

Analysts say the water dump could harm Prime Minister Fumio Kishida's standing with domestic voters and neighboring governments.

Engineers at the power station, which was crippled in the March 2011 earthquake and tsunami, causing three of its six reactors to suffer meltdowns, began discharging water through a pipeline that has been constructed to a distance of about one kilometer (0.6 miles) off the coast.

The Japanese government and Tokyo Electric Power Co (TEPCO), the operator of the facility, have gone to great lengths to convince the Japanese public and the international community that the water is safe.

They point out that the water has been treated to remove virtually all the radioactive contaminants, that it is being greatly diluted and that studies endorsed by the International Atomic Energy Agency show that it poses no threat to human health or the flora and fauna of the Pacific.

However, China has demonstrated its disagreement with this assessment by announcing Thursday it would ban all seafood from Japan in response to the Fukushima water release, which it called "selfish and irresponsible."
Japan divided on Fukushima water dump

The Japanese public is divided on the matter, with environmental groups, opponents of nuclear energy and people living in northeast Japan, particularly fishermen, furious at the decision.

Others, however, are shrugging their shoulders and suggest the government had little choice in the matter.

"Kishida is already dealing with a number of problems in his government, including rising prices and scandals involving his son, who was serving as an aide, and in the party, so this issue is certainly going to add to his problems," said Hiromi Murakami, a professor of political science at the Tokyo campus of Temple University.

"But it goes both ways," she told DW. "Among those opposed to his conservative government, this will be something else to criticize him for, but conservatives see this as progress that is finally being made in a problem that has been lingering for the last decade."

Ken Kato, a businessman from Tokyo, applauded the decision after so many delays.

"I am 100% supportive and this is the only appropriate action," he told DW.

"The IAEA has confirmed that it is of no danger to human health. The most serious issue is the Chinese misinformation campaign that has served to damage the reputations and livelihoods of fishermen in north-east Japan and Japan in general," he added.

Others take issue with that position, however, with Kanako Hosomura, a housewife from Saitama Prefecture, less than 200 kilometers southwest of the nuclear power plant, saying she is fearful of the impact of the water release.

"It is obvious that fish, shellfish, seaweed and other food products from the region are going to be affected over time by this," she told DW.

"I'm not going to buy fish from Fukushima again and I will ask the sushi restaurant where I usually go where they are buying their stocks from. And I definitely will not go to any of the beaches there with my children until I am absolutely sure that it is safe again."

How is the water being treated?

TEPCO officials have stated that an initial 7,800 tons of water, which has undergone treatment in the Advanced Liquid Processing System (ALPS) to remove all but the relatively harmless radionuclide tritium, will be diluted with seawater and released over the next 17 days.

The water is diluted to reduce tritium levels to one-seventh the standard set by the World Health Organization as being safe to drink, the company said.

Monitored by the IAEA, TEPCO intends to release around 31,200 tons of treated water in the fiscal year to April.

Experts estimate that it will take around 30 years to release the 1.25 million tons of water that is already in storage at the site and all additional rainwater that seeps into the subterranean complex that houses the damaged reactors


What is the international reaction?


The United States said it is satisfied with the safety measures Japan is taking, and Ambassador Rahm Emanuel stated that he will be travelling to Fukushima later this week and intends to visit a sushi restaurant to demonstrate US solidarity. Australia has expressed similar support.

The government of South Korean President Yoon Suk-yeol also said it is satisfied that the science supports the decision to discharge the water, but with growing public anger over the move domestically, it has added the condition that it will take Japan to court should radiation be detected above safe levels.

However, Lee Jae-myung, the head of South Korea's Democratic Party, has called the water release an "act of terror."

Ben Ascione, an assistant professor of international relations at Tokyo's Waseda University, said strong opposition from China was inevitable, but that the water release could negatively affect Japan's "fragile" relations with South Korea.

"China's position has been steadfast and this is not going to change the relationship too much, but the situation with Seoul is more complicated," he said.

"Japan, South Korea and the US have just had a very important trilateral summit at Camp David and there have been triumphant claims that this is a completely new era of relations. My reading is that it is a lot more fragile than that triumphalism would have us believe," he added.

"This is going to continue to be another thorn in the side of the relationship and an issue where tensions are going to continue to flare," he said.
