Eighty years after the United States dropped atomic bombs on Hiroshima and Nagasaki to end the Second World War, the threat of nuclear fallout remains.

Last Monday, the UN Human Rights Council issued a formal communication to the Japanese government regarding serious concerns raised by Pacific communities about the dumping of 1.3 million metric tonnes of treated Fukushima nuclear wastewater into the ocean over 30 years.

The council warned that the release could pose major environmental and human rights risks.

Te Ao Māori News spoke with Mari Inoue, a NYC-based lawyer originally from Japan and co-founder of the volunteer-led group The Manhattan Project for a Nuclear-Free World.

Recently, at the UN, they called for global awareness, not only about atomic bomb victims but also of the Fukushima wastewater release, and nuclear energy’s links to environmental destruction and human rights abuses.

Formed a year after the Fukushima nuclear disaster, the group takes its name from the original Manhattan Project — the secret Second World War  US military programme that raced to develop the first atomic bomb before Nazi Germany.

A pivotal moment in that project was the Trinity Test on July 16, 1945, in New Mexico — the first successful detonation of an atomic bomb. One month later, nuclear weapons were dropped on Hiroshima and Nagasaki, killing an estimated 110,000 to 210,000 people.

Seeking recognition and justice
Although 80 years have passed, victims of these events continue to seek recognition and justice. The disarmament group hopes for stronger global unity around the Non-Proliferation Treaty, and more support for victims of nuclear exposure.

The anti-nuclear activists supported the Non-Proliferation Treaty (NPT), which seeks to prevent the spread of nuclear weapons. Their advocacy took place during the third and final preparatory committee for the 2026 NPT review conference, where a consensus report with recommendations from past sessions will be presented.

Inoue’s group called on the International Atomic Energy Agency (IAEA) to declare Japan’s dumping policy unsafe, and believes Japan and its G7 and EU allies should be condemned for supporting it.

Nuclear energy for the green transition?
Amid calls to move away from fossil fuels, some argue that nuclear power could supply the zero-emission energy needed to combat climate change.

Inoue rejects this, saying that despite not emitting greenhouse gases like fossil fuels, nuclear energy still harms the environment.

She said there was environmental harm at all processes in the nuclear supply chain.

Beginning with uranium mining, predominantly contaminating indigenous lands and water sources, with studies showing those communities face increased cancer rates, sickness, and infant mortality. And other studies have shown increased health issues for residents near nuclear reactors.

“Nuclear energy is not peaceful and it‘s not a solution to the climate crisis,” Inoue stressed. “Nuclear energy cannot function without exploiting peoples, their lands, and their resources.”

She also pointed out thermal pollution, where water heated during the nuclear plant cooling process is discharged into waterways, contributing to rising ocean temperatures.

Inoue added, “During the regular operation, [nuclear power plants] release radioactive isotopes into the environment — for example tritium.”

She referenced nuclear expert Dr Arjun Makhijani, who has studied the dangers of tritium in how it crosses the placenta, impacting embryos and foetuses with risks of birth defects, miscarriages, and other problems.

Increased tensions and world forum uniting global voices
When asked about the AUKUS security pact, Inoue expressed concern that it would worsen tensions in the Pacific. She criticised the use of a loophole that allowed nuclear-powered submarines in a nuclear-weapon-free zone, even though the nuclear fuel could still be repurposed for weapons.

In October, Inoue will co-organise the World Nuclear Victims Forum in Hiroshima, with 2024 Nobel Peace Prize winner Nihon Hidankyo as one of the promoting organisations.

The forum will feature people from Indigenous communities impacted by nuclear testing in the US and the Marshall Islands, uranium mining in Africa, and fisheries affected by nuclear pollution.

A Japanese government spokesperson says it is “not wilfully trying to divide the Pacific” over the Fukushima treated nuclear wastewater release.

Japan is set to start discharging more than one million tonnes of treated nuclear wastewater into the Pacific Ocean tomorrow (local time).

This comes 12 years after a tsunami slammed the Fukushima Daiichi nuclear power plant resulting in what has been labelled as the largest civil nuclear energy disaster since Chernobyl.

Palau, Papua New Guinea, Cook Islands and the Federated States of Micronesia have publicly backed the plan or at least placed their faith in Japan’s word that it will be safe.

The release is forecast to take 30 to 40 years to complete.

Fiji’s Prime Minister Sitiveni Rabuka is the most recent Pacific leader to speak out in defence of Japan.

He said he is satisfied their plan is safe after reading the UN nuclear agency’s report.

Rabuka’s voice is important because he is in the Pacific Islands Forum leadership team — known as the Troika — as the past chair of the Forum. The other two are current chair Cook Islands Prime Minister Mark Brown and future chair, the Tongan Prime Minister Hu’akavameiliku Siaosi Sovaleni.

Since making that statement Rabuka has apologised for speaking ahead of the recent Troika meeting, but he has not backtracked on his view.

‘Discharged’ into Japan’s own backyard
Rabuka has taken to social media in response to criticism of his statement of support.

“Comparisons between the nuclear legacy in the Pacific and Japan’s nuclear wastewater release is fear-mongering,” he wrote.

He also said the wastewater was not being dumped but discharged into Japan’s “own backyard”, over 7000km from Fiji.

1/3 One of my critics at the weekend appeared to be somehow connecting the wastewater discharge with the cataclysmic power of the nuclear bombs dropped in the Pacific as part of weapons testing.

That in itself has been the centre of debate with nuclear activists continuing to call it a dump.

One nuclear expert appointed by the Pacific Islands Forum said there was an argument that it was a dump over a release.

But the International Atomic Energy Agency has gone to great lengths — even travelling to New Zealand and Rarotonga — to explain why this is not a dump.

Director-General Rafael Grossi told RNZ Pacific earlier this year that he condemned dumping which he said had happened in the past and was not the case for Japan’s plan.

Against and on the fence
Vanuatu’s Foreign Minister has drafted a declaration urging Japan to stop the discharge.

He wants the leaders of the Melanesian Spearhead Group (MSG) meeting in Port Vila today to support the declaration.

Tuvalu has also spoken out, expressing opposition to Rabuka’s stance.

Tuvalu’s Minister for Finance, Seve Paeniu told FBC News that if Japan was genuinely confident, why did it not consider disposing of it within its own lakes and waters.

TEPCO assures the Pacific
Tokyo Electric Power Company Holdings (TEPCO) spokesperson Junichi Matsumoto told the first media briefing today that his team was “moving quickly” to prepare the release which would depend on the conditions.

“The final decision will be made on the morning of the [August] 24 based on the climate conditions or weather conditions,” he said.

“A very small amount will be carefully discharged using a two-step process.”

RNZ asked TEPCO about the nuclear legacy in the Pacific.

“To the members of the PIF, we have been providing explanations on the discharge into the sea,” Matsumoto said.

“So we would like to continue to provide the explanation on our initiative.

“And in terms of assurance, it may be a bit different in terms of nuance, but the result of sea area monitoring will be communicated.

Matsumoto said anyone wishing to could check the results of the sea area monitoring on the TEPCO website.

When questioned about when Pacific nations would see the effects of the release, he said that according to dispersion models particles would arrive on the shores of Papua New Guinea and Fiji in “a few years’ time or a few decades”.

“It will be impossible to distinguish that [discharged] tritium [in the Pacific Ocean] from that already existing in nature,” Matsumoto said.

A Japan government spokesperson said Tokyo was not wilfully trying to divide the Pacific and no compensation would be given to Pacific nations for potential reputational damage.

“The Japanese government has been taking opportunities at international conferences and at bilateral meetings to thoroughly and meticulously explain and disseminate information to the world through its website, as well as through social network media including X [formerly Twitter],” the spokesperson said.

The Women’s International League for Peace and Freedom (WILPF) Aotearoa, the longest running women’s peace group in New Zealand, has called on the Japanese government to change its plan to release treated nuclear wastewater from the Fukushima Daiichi nuclear power station into the Pacific Ocean.

The protest comes as Pacific leaders remain undecided over the controversial — and widely condemned — Japanese move as reports suggest the start of the wastewater release could begin in the next few days.

“Releasing more radioactive materials is a wilful act of harm that will spread further radioactive contamination into the global environment,”said WILPF in its protest letter sent to Japanese Ambassador Ito Koichi last weekend.

“The treated water contains tritium, which cannot be removed. Tritium will be dumped into the ocean for several decades.

“There has been no assessment of future biological impacts. Nor has there been a review of less expensive and safer alternatives.”

An RNZ Pacific report said today that the past, present and future Pacific Islands Forum (PIF) chairs — known as “the Troika” — had not decided if they were for or against the imminent discharge.

The Melanesian Spearhead Group (MSG) meeting in Port Vila, Vanuatu, this week has been urged to call on Japan to drop plans for the wastewater release.

Accident reminder
WILPF reminded the Japanese government in its protest letter that after the 2011 earthquake and tsunami which caused the accident at the power station, the radioactive contaminated water was treated by a multi-nuclide removal system (ALPS) and stored in more than 1000 tanks on the power plant site.

It also reminded Tokyo of its pledge about Fukushima at the time.

The Japanese government and the operating company, TEPCO, stated that this water would not be disposed of in any way without the understanding of the concerned parties and would be stored on land.

The London Convention, which Japan ratified in 1980, strictly regulates the dumping of radioactive waste into the ocean.

“Therefore,” said the protest letter, “the release of treated water is a violation of international law.

“Such an action would also damage the trust between Japan and its neighbours and the Pacific Islands.”

Japan plans to start releasing treated nuclear wastewater from the tsunami-wrecked Fukushima nuclear power plant into the ocean as soon as later this month, Japan’s Asahi Shimbun daily is reporting, citing government sources.

The newspaper said the release was likely to come shortly after Prime Minister Fumio Kishida meets US President Joe Biden and the South Korean President, Yoon Suk-yeol, next week in the US, where Kishida planned to explain the safety of the wastewater.

Japan’s nuclear regulator last month granted approval for plant operator Tokyo Electric Power (TEPCO) to start releasing the water, which Japan and the International Atomic Energy Agency (IAEA) say is safe but nearby countries fear may contaminate food.

Bottom-trawling fishing was scheduled to start off Fukushima, north-east of Tokyo, in September, and the government aimed to start the water discharge before the fishing season got under way, the newspaper said.

In July the UN’s nuclear watchdog approved plans by Japan to release the water, despite objections from local fishing communities and other countries in the region.

About 1.3m tonnes of water stored in huge tanks on the site has been filtered through TEPCO’s advanced liquid processing system (ALPS) to remove most radioactive elements except for tritium, an isotope of hydrogen that is difficult to separate from water.

500 Olympic pool sized
The treated water will be diluted with seawater so that the concentration of tritium is well below internationally approved levels before being released into the ocean 1km from the shoreline via an undersea tunnel.

The water — enough to fill 500 Olympic-sized swimming pools — became contaminated when it was used to cool fuel rods that melted after the power plant was hit by a powerful earthquake and tsunami in March 2011.

Discharging the water is expected to take 30 to 40 years to complete.

Attempts by Japanese government officials to win regional support for the plan have had limited success.

China denounced the plan as “extremely irresponsible” when it was announced in 2021. Hong Kong has threatened to ban food imports from 10 Japanese prefectures if the water release goes ahead as planned.

Independent nuclear experts have offered to drink water and eat fish from the Pacific Ocean after Japan dumps its nuclear waste water into the Pacific.

Japan is planning to ditch over one million tonnes of ALPS-treated radioactive wastewater from the damaged Fukushima Daiichi nuclear power plant into the Pacific Ocean over 30 to 40 years starting from sometime this year.

ALPS is an Advanced Liquid Processing System.

New Zealand and Australian experts told media at an online panel discussion hosted by NZ’s Science Media Centre that Japan had good intentions.

The experts said they believed that as long as the wastewater was tested before it was released the operation would be safe.

Two even went as far as saying they would “take a sip” of the treated wastewater.

“I would drink the water. I mean, it’s like going down to the beach and swallowing a mouthful of water when you’re swimming,” said University of Auckland physics senior lecturer Dr David Krofcheck.

“It’s saltwater. I prefer the desalinated before I drink it,” he added. Dr Krofcheck specialises in nuclear physics and natural radiation from the environment.

“Would I eat the fish? Yes, I would,” Adelaide University’s School of Physics, Chemistry and Earth Sciences associate professor Tony Hooker added.

‘The least bad option’
The contaminated water has been used to cool the melted reactor of the damaged Fukushima Daiichi nuclear power plant.

More than 1000 tanks are now full and Tokyo Electric Power Company (TEPCO) is running out of storage space.

Japan has said it will treat the water to ensure it is harmless. It will also dilute the water and then release it into the Pacific Ocean.

Dr Krofcheck said that option was the “best one”.

“That’s probably the least bad option. Not that that’s a bad option. Because the dose, or the amount of tritium being diluted is so small. But I think the least bad option is releasing,” he said.

Ocean circulation modeller and researcher in Taiwan, Professor Chau-Ron Wu, told media he predicted the water from Fukushima would take 2-3 years to reach North America, one year to get to Taiwan and sweep across much of the Pacific.

No release date has been set, but associate professor Tony Hooker said that what was known is, “The water is going to be released in [northern hemisphere] summer 2023.”

“I think the release is imminent. And I guess that will be a decision for the Japanese government. Ultimately, they can make that decision. They don’t need to rely on the International Atomic Energy Agency or any other agency.”

Associate professor Hooker said that as long as it was only tritium and carbon 14 that’s released, and in small quantities, he is confident it would be safe.

Dr Krofcheck agrees: “I’m very comfortable with releasing it, as long as we can guarantee the Royal Science Society can guarantee that the nasty strontium, caesium, iodine, cobalt 60 can be removed”.

They will be removed by an ALPS.

“So, most of the ALPS processes are using a zeolite clay and which is very absorbent. Once the water has gone through that the radionuclides are bound to a solid, you can dry that out and store it as radioactive waste,” Hooker explained.

‘I really thought they reconsider it’
There is still a lot of uncertainty across the Pacific about the release project.

Japan is in talks with the Pacific Islands Forum (PIF) and has been providing data to their independent expert panel to analyse, which Hooker is a part of.

He acknowledged those who want to end nuclear waste dumping, which he says already happens around the world.

“Whilst there’s no issues from a radiation safety perspective about putting this radiation into the sea, should there be some level of discussion or intensive research about how we can minimise disposing into the sea in the future?”

‘Retraumatising’ for Tahitian
A Mā’ohi anti-nuclear activist in Tahiti, Hinamoeura Cross, found the news of Japan pushing forward with its plans despite backlash retraumatising.

“I’m really shocked by what the Japanese are going to do. We know that they have planned that for many years, but I really thought that they will reconsider that,” Cross said.

For her, all nuclear issues are personal. Japan’s plans are of interest in particular as they impact on her ocean, the Pacific.

“I remember my great grandmother and my grandmother that were sick. Then my mum and my auntie, they had the thyroid cancer,” Cross said.

When Cross was aged about 10, her sister got sick and at 23-years-old she was diagnosed with leukaemia.

All of the women she loves and looked up to were “poisoned” by French nuclear testing in the Pacific, she said.

Now that she is a mother of two, her voice has become staunchly against nuclear colonialism. She wants better healthcare for survivors of French nuclear testing.

“I’m anxious about the health care of my children; are they going to be sick or not? We really need this healthcare in Tahiti because of the 193 nuclear bomb (tests that France detonated in the Pacific),” Cross said.

Pacific reacts to Japan’s plans
Pacific leaders have been voicing their views on the upcoming release, which Japan says it needs to do in an effort to make progress on decommissioning the power plant.

Papua New Guinea Prime Minister James Marape is the latest leader to issue his support after being assured of the project’s safety by Japan.

Safety is a sentiment echoed by TEPCO, the owners of the plant.

“The release into the sea from the Fukushima Daiichi nuclear (plant) would be the most realistic approach,” TEPCO Chief Officer for ALPS treated water management Junichi Matsumoto told RNZ Pacific in January 2023.

The dumping operation is expected to take between 30 and 40 years as it needs to be treated by the ALPS system and then diluted by sea water to meet regulatory standards.

The International Atomic Energy Agency (IAEA) is reviewing the processes.

The IAEA’s latest report has found TEPCO has managed to demonstrate it can measure the radionuclides in the treated water stored on site accurately and precisely.
