What’s dumped is not just Fukushima nuclear water

In January, the Japanese government announced that it would begin to release into the Pacific Ocean more than 1.37 million tons of water from the wrecked Fukushima Daiichi nuclear plant sometime this spring or summer. A shadow of nuclear contamination is looming larger.

Although the Tokyo Electric Power Company (TEPCO) insists that the contaminated water has been filtered and diluted and meets the criterion for a safe discharge, a report has shown that 73 percent of the treated water still exceeds the discharge standard.

Unlike normal wastewater from nuclear power plants, Fukushima nuclear-contaminated water contains over 60 kinds of radioactive substances. Besides tritium, which is difficult to remove, the treated water also contains strontium-90 and carbon-14, whose half-lives are 29 years and 5,730 years, respectively.

For those who can’t grasp its meaning, tritium can replace stable hydrogen atoms in the human body and cause chronic radiation syndrome and cancer. Strontium-90 is highly toxic and may induce bone tumors.

Experts have pointed out that once released into the ocean, the contaminated water would rapidly spread to most parts of the Pacific. Radiation would be absorbed by marine life and enters the human body.

In 2022, it was detected that radiation in black rockfish caught off Fukushima prefecture was 14 times higher than the safe level for humans, even after 11 years have passed since the Fukushima nuclear disaster. The South China Morning Post reported that caesium, one of the most dangerous radionuclides that “can build up in muscle, fat and bone and cause malignant tumors,” was detected in “fish caught at a depth of 24 meters about 9 km off Fukushima prefecture’s town of Shinchi.”

After more than 10 years, the local fishery industry has not fully recovered. In 2012, Japan banned the sale of 36 species of fish caught off Fukushima, and Tokyo’s decision crushed their hopes. Voices of opposition have been ongoing. In Japan, fishery organizations have expressed their concerns. Citizens in Tokyo, Osaka and Shizuoka protested on the streets to demand the government rescind its decision.

On the world stage, Japan’s neighbors including China, Russia and South Korea have asked Tokyo to provide useful information, engage in full consultation, and take responsible measures. The Pacific Island countries urged Japan not to release the contaminated water before there is enough scientific evidence proving that it’s safe. And independent UN human rights experts issued a joint statement calling Japan’s decision “very concerning” and “deeply disappointing.”

To make a clear evaluation of the safety of Japan’s plan, an International Atomic Energy Agency task force was set up to conduct a safety review. Days ago, it completed its second regulatory review and “will release a report on its findings in about three months, as well as a comprehensive report before the discharge.” Nonetheless, even before the task force set out, Tokyo unilaterally announced the planned discharge. The Japanese government has set its mind on the discharge regardless of the review outcome.

When Tokyo decides to discharge the contaminated water without ensuring safety, does it even consider people’s right to life and health? As a party to the UN Convention on the Law of the Sea, the Convention on Early Notification of a Nuclear Accident, and the Convention on Nuclear Safety, does the Japanese government recognize its international obligations? When it puts the whole Pacific and Pacific Rim countries at the risk of environmental disaster, how does it uphold the principle of “environment first”?

When it comes to nuclear contamination, it’s better to err on the side of caution. There could be better alternatives than dumping the contaminated water into the sea. Evaporating, storing underground the tritium-laced water from the plant, or storing and processing the water over the long term, these are all technically reasonable options that are safer than a direct discharge. Unfortunately, Tokyo has chosen to go for the cheapest “quick fix.”

When the earthquake and tsunami struck Fukushima, neighboring countries reached out their helping hands to Japan. Today, the nation is repaying them with tons of nuclear contaminated water.

The Pacific Ocean is home to billions of people, but Japan takes it as its own sewer. Along with contaminated water, Japan’s reputation, conscience and international obligations will be dumped as well.

Japan Plans to Dump Fukushima Wastewater Into a Pacific With a Toxic Nuclear History

In December, the U.S.-based National Association of Marine Laboratories also announced its opposition to TEPCO’s plans, publishing a position paper that says “there is a lack of adequate and accurate scientific data supporting Japan’s assertion of safety” while “there is an abundance of data demonstrating serious concerns about releasing radioactively contaminated water.”

BY AMY GUNIA , FEBRUARY 6, 2023,

Pacific Island nations have for decades been grappling with the environmental and health consequences of Cold War-era nuclear testing in the region by the likes of the U.S. and France. Now, they worry about another kind of nuclear danger from neighbors much closer to home.

As concerns over energy security and the desire to transition away from fossil fuels pushes several Asian nations to reconsider once-scrapped nuclear power programs, there is increasing anxiety over how the waste from those facilities—depending on the methods of disposal—might impact the lives of Pacific Islanders.

Notably, in the region, Philippines President Ferdinand “Bongbong” Marcos said in his first address to Congress in mid-2022 that he was open to adding nuclear energy to the country’s energy mix, the Indonesian government said in December it plans to build a nuclear power plant by 2039, and weeks later Japan announced that it plans to ramp up the use of nuclear energy.

Nuclear plants have long been touted as a reliable source of carbon-free energy, though many plants across the world had been shuttered in past decades over worries about the safety of nuclear waste disposal. In this new era of nuclear revival, similar uncertainties abound.

In Japan, one plant that isn’t even operational has become the frontline for the fight between activists seeking safety assurances for waste disposal and operators who are running out of space in on-site tanks to store the wastewater accumulating from keeping damaged reactors cool. Currently, Japan plans to release wastewater from the Fukushima Daiichi nuclear power plant into the Pacific Ocean later this year.

“It’s just horrendous to think what it might mean,” says Henry Puna, the secretary general of the Pacific Islands Forum (PIF), a regional intergovernmental organization that has more than a dozen member countries, including, for example, the Cook Islands, Fiji, Tonga, and Vanuatu. “The people of the Pacific are people of the ocean. The ocean is very much central to our lives, to our culture, to our livelihoods. Anything that prejudices the health of the ocean is a matter of serious concern.”

When a magnitude 9.1 earthquake and tsunami hit off the coast of Japan in 2011, it caused a meltdown at the Fukushima nuclear power plant. Since then, water is being used to cool the damaged reactors and prevent further catastrophe. Now, more than 1.3 million metric tons of radionuclide-contaminated water has been collected on site, and it continues to accumulate, as rain and groundwater seep in. Tokyo Electric Power Company (TEPCO), the operator of the plant, says that the storage tanks take up too much space and hinder decommissioning the plant.  Japan initially said that it would begin releasing the water into the ocean in the spring of 2023. Chief Cabinet Secretary Hirokazu Matsuno told the media in January that the release target date is now around spring or summer, which appears to be a postponement, according to the Associated Press, due to construction delays on a pipeline and the apparent need to gain greater public support.

The plan has faced widespread opposition. Japanese fishermen, international environmentalists, and other governments in the region, including China, South Korea, and Taiwan, have all expressed concern. Some of the strongest pushback has come from Pacific Island countries, including from lawmakers, former leaders, regional fisheries management groups, and other organizations. Among those voices is the PIF, which is advocating for more time to deal with questions and concerns. Earlier this year, the PIF appointed a panel of independent global nuclear experts to help inform its members in their consultations with Japan and TEPCO. The experts have stressed that more data are needed to determine the safety of the water for disposal.

“We think that there is not enough scientific evidence to prove that the release is safe, environmentally, healthwise, and also for our economy in the Pacific,” says Puna, who is also the former Prime Minister of the Cook Islands. Until more information is shared and evaluated, he asks that Japan “please defer the discharge of the water.”

…………………………….  there appears to be a major disconnect between TEPCO and others, including the PIF panel of experts—who say that they’re concerned with the adequacy, accuracy, and reliability of the data backing up the decision to release the water.

Robert H. Richmond, a research professor and the director of the Kewalo Marine Laboratory at the University of Hawaii at Manoa, who is one of the panel experts, tells TIME that “the critical, foundational data upon which a sound decision could be made was either absent or, when we started getting more data,” he says, “extremely concerning.” He also casts doubt on if the IAEA is in the best position to assess the risks. “They’re an agency that has a mandate to promote the use of nuclear energy,” says Richmond, “and our mandate is to look after the people, the ocean, and the people who depend on the ocean. And our unanimous conclusion … is that this is a  bad idea that is not defended properly at this point, and that there are alternatives that Japan should really be looking at.”

“One of the biggest surprises to me was the fact that the data was so sparse,” says Ferenc Dalnoki-Veress, scientist-in-residence and adjunct professor at the James Martin Center for Nonproliferation Studies at the Middlebury Institute of International Studies at Monterey, who is also on the PIF panel of experts. “There were prolonged gaps in data collection, which suggests that the matter may not have been given the level of attention and importance it deserved.” He adds that only a fraction of the tanks had been sampled, and only a handful of some 60 isotopes were typically measured in the samples—fewer than he would expect for this kind of assessment. (TEPCO says that the analysis done on a sample of tanks so far is just to assess the water’s condition in storage but that, after the purification process, further measurements will be taken on all the treated water before discharge to ensure that only that which meets sufficient standards of safety is released into the ocean).

Some still fear the safety of the treated water, and the far-reaching implications if it’s dumped into the ocean. Puna points out, for example, that the waters of the Western and Central Pacific Ocean produce much of the world’s tuna. If the tuna were to be impacted, it would cause major problems for Pacific nations, for which fisheries are a significant source of income, as well as for consumers globally.

In December, the U.S.-based National Association of Marine Laboratories also announced its opposition to TEPCO’s plans, publishing a position paper that says “there is a lack of adequate and accurate scientific data supporting Japan’s assertion of safety” while “there is an abundance of data demonstrating serious concerns about releasing radioactively contaminated water.”

……………………………………. A scarring past and a new path forward

Other nuclear plants across the globe have released treated wastewater containing tritium. Rafael Mariano Grossi, the IAEA’s director general, said in 2021 that Japan’s plan is “in line with practice globally, even though the large amount of water at the Fukushima plant makes it a unique and complex case.”

But Pacific Island nations have particular reason to be anxious. There is a noxious legacy of nuclear testing in the region, and other countries have historically treated the Pacific as a dumping ground for their waste. The U.S. conducted 67 nuclear tests in the Marshall Islands between 1946 and 1957—and disposed of atomic waste in Runit Dome, where it’s still stored. That testing led not only to forced relocations, but also to increased rates of cancers. Today there is concern that the dome is leaking and that rising sea levels might impact its structural integrity. France also conducted 193 nuclear tests from 1966 to 1996 at Moruroa and Fangataufa atolls in French Polynesia.

…………………….. Rather than let dumping wastewater into the ocean become the norm, at this juncture for nuclear energy, some say it’s an opportunity to explore different ways of doing things. The panel of PIF experts has proposed several alternative solutions, including treating the water and storing it in more secure tanks to allow the tritium time to decay, or using the treated water to make concrete for use in projects that won’t have high contact with humans.

“This is not the first nuclear disaster and by no means is it going to be the last,” says Richmond. “This is an opportunity for Japan,” he says, “to do the right thing and to invest time, effort, and money into determining and coming up with new ways of handling radioactive waste and setting a new trajectory.”
