The International Atomic Energy Agency has announced that its experts have confirmed that the tritium concentration in the latest batch of water to be released from the Fukushima Daiichi nuclear power plant is far below Japan’s operational limit. Tokyo Electric Power Company (TEPCO) began discharging the treated and diluted water on March 12.
International Atomic Energy Agency director general Rafael Mariano Grossi visited Japan’s Fukushima Daiichi site on February 19, where he joined scientists from the Third Institute of Oceanography in China, the Korean Institute for Nuclear Safety in South Korea, and the Spiez Laboratory in Switzerland in collecting seawater samples from a boat near the damaged nuclear power plant.
It’s been less than two years since Germany shuttered its three remaining nuclear plants on April 15, 2023—the culmination of a decision reached during the backlash following the Fukushima Daiichi accident in Japan in 2011.
During some of his first public remarks last week, Japan’s new economy minister Yoji Muto promoted the importance of nuclear energy for his nation.
Muto said the new administration—including newly appointed prime minister Shigeru Ishiba—plans to restart “as many reactors as possible so long as they are safe,” reported NucNet, a nuclear-centered news agency in Brussels.
The International Atomic Energy Agency announced on Aug. 7 that its experts have confirmed that the tritium concentration in the latest batch of water to be released from the Fukushima Daiichi nuclear power plant is far below Japan’s operational limit. Tokyo Electric Power Company (TEPCO) began discharging the treated and diluted water that day.
An International Atomic Energy Agency task force has confirmed that the discharge of treated water from Japan's Fukushima Daiichi nuclear power plant is progressing in accordance with the plan approved by Japan’s Nuclear Regulation Authority.
International Atomic Energy Agency experts have confirmed that the tritium concentration in the fourth batch of treated water released from Japan’s Fukushima Daiichi nuclear power plant is far below the country’s operational limit.
Japanese regulators have ordered further review at a nuclear power plant in central Japan following a series of deadly earthquakes that rocked the country on New Year’s Day.
The new year is here, and so it is time for the Nuclear News review of 2023's top stories. The recap will appear in the January issue of the magazine, on its way to American Nuclear Society members right now. In the meantime, all ANS members can read the year's issues in the ANS member center, and also review some of the most-read stories from Nuclear Newswire below. Here’s to a Happy New Year!
A series of earthquakes on New Year’s Day that resulted in a tsunami warning and prompted evacuations from Japan’s west coast caused no irregularities at the country’s nuclear plants, Japanese officials have reported.
The “How do we talk about the Back End?” session at the ANS Winter Conference & Expo on Wednesday, November 15, focused on recent experiences in communicating about used nuclear fuel to a skeptical public.

Earlier this week, Japan announced its intention to move ahead with its plan to discharge re-treated, diluted tritiated wastewater from the damaged Fukushima Daiichi Nuclear Power Plant into the ocean. This plan has been a topic of discussion--and for many a source of contention--since 2013. After a decade of talks, and with the endorsement of nuclear scientists, experts, and organizations around the globe, the time has come to act. By following safety standards in place and endorsed by the IAEA, the release of wastewater will pose no threat to the public or the environment.
The article below was originally published in the March 2021 issue of Nuclear News. (Also included in that issue is a great review article from Lake Barrett outlining the current status of the decontamination and decommissioning going on at Fukushima .) That month marked 10 years since the Tōhoku earthquake and tsunami devastated Japan and crippled the Fukushima plant. The words that follow remain timely, since various news outlets continue to report on the dangers of Fukushima's wastewater without providing context to the Japanese plan to discharge it.
Treated water is safer than world standards, essential for decommissioning
Washington, D.C. – The American Nuclear Society (ANS) supports the start of Japan’s controlled release of re-treated, diluted tritium wastewater into the sea from the Fukushima Daiichi Nuclear Power Plant (NPP), which sustained damage in the aftermath of a 2011 earthquake and tsunami.
International Atomic Energy Agency experts at Ukraine’s Russian-occupied Zaporizhzhia nuclear power plant have so far been unable to verify recent claims by Ukrainian president Volodymyr Zelenskyy that Russia may have planted explosives at the site to “simulate an attack.”

We’ve all seen the headlines such as “Should Japan Dump Fukushima's Radioactive Water into the Ocean?” along with “Japan Set to Pour Fukushima Waste into Pacific, Irking China” and “Japan Is Slowly but Surely Releasing Wastewater from the Fukushima Nuclear Plant into the Pacific Ocean.” The most recent spate of fearmongering was triggered by the IAEA’s July 4 announcement that the agency had finished its independent assessment of Japan’s plans to release the treated wastewater stored at the Fukushima Daiichi nuclear power station and found the plan “consistent with IAEA Safety Standards.”

In his new film Nuclear Now, Oliver Stone brings his seasoned directorial hand to bear on the modern case for nuclear energy. Of course, all of us in the field are suckers for a good nuclear movie. (Triple feature with Pandora’s Promise and A New Fire, anyone?) Stone really does do a masterful job of weaving imagery, narration, and animation together to tell the story of his personal journey to understanding the indispensability of nuclear.
What struck me in particular was Stone’s assertion that “we are running out of time to be afraid.” It made me think: How much time do we have left to lock in a durable shift in public opinion that can weather adverse events and clear public policy obstacles and still give the investment community confidence to put big chips on the table?
You don’t have to look far to find progress. Gallup released its annual “Americans’ Opinions of Nuclear Energy” poll in April. It shows a 4-point year-over-year increase in support for nuclear energy, which represents the highest level of support in the post-Fukushima era. Gallup’s numbers align with other polls that show steady increases in support for nuclear in the last few years, especially among the left-leaning respondents.
The trouble with tritium is there is no trouble with tritium.
At any level outside the laboratory, either experimental or manufacturing, tritium is harmless. Every year, we routinely release millions of gallons of slightly tritiated water to the ocean, large lakes, and large rivers from almost every commercial nuclear reactor in the world, and have done so for decades, all in accordance with globally accepted nuclear safety standards. And no adverse effects on the environment or humans have ever been seen.
German chancellor Olaf Scholz has provided what appears to be the final word on the fate of his country’s three remaining operating nuclear power plants.
Via an October 17 letter, Scholz informed economy and energy minister Robert Habeck, environment minister Steffi Lemke, and finance minister Christian Lindner of his decision to keep all three facilities operating “beyond 31 December 2022 until 15 April 2023 at the latest.” The order ends months of argument between Scholz’s two coalition partners—the stridently antinuclear Greens and the center-right Free Democrats (FDP)—regarding the plants’ continued operation. (Habeck and Lemke are Green Party members, while Lindner is with the FDP.)
The International Atomic Energy Agency, for the second successive year, has revised upward its annual projections of nuclear power’s potential growth over the coming decades as an electricity provider.
In the just-released 42nd edition of Energy, Electricity and Nuclear Power Estimates for the Period up to 2050, the IAEA has increased its high-case scenario for nuclear by 10 percent over last year’s report. (In 2021, the agency revised upward its annual projections for the first time since the 2011 Fukushima Daiichi accident.)
According to the high-case scenario, world nuclear generating capacity more than doubles to 873 GWe by 2050, compared with current levels of about 390 GWe—an addition of 81 GWe to last year’s projection. In the low-case scenario, generating capacity remains essentially flat.
Kishida
Having already declared last month his government’s intention to return to service as many as nine idled power reactors in order to ensure stable supplies of energy this winter, Japanese prime minister Fumio Kishida yesterday called for additional restarts and endorsed the development and construction of next-generation nuclear plants, according to reports from various news outlets, including Nikkei Asia, the Washington Examiner, and the Los Angeles Times.
Kishida made the comments at the second meeting of Japan’s GX (Green Transformation) Implementation Council, a new group tasked with helping the country achieve carbon neutrality by 2050.
