Blaming “the criminal actions of the ruscists,” Ukraine nuclear plant operator Energoatom this morning reported a primary-to-secondary reagent leak at Unit 5 of the Russian-occupied Zaporizhzhia nuclear power plant (ZNPP), as well as a partial blackout at the facility earlier this week. (The term “ruscist” [рашизм] is a portmanteau of the words “Russian” and “fascist.”)

The European Union has selected a Westinghouse-led consortium to develop and deliver “a secure, fully European nuclear fuel supply” for Russian-designed VVER reactors in the EU and Ukraine, the U.S.-based firm announced last week.

No evidence yet of explosives planted at Zaporizhzhia, says IAEA

July 6, 2023, 3:00PMNuclear News

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.”

Destruction of Ukrainian dam threatens Zaporizhzhia

June 6, 2023, 3:00PMNuclear News

A Soviet-era dam downstream from the Zaporizhzhia nuclear power plant in southeastern Ukraine collapsed last evening, causing the water level of the Kakhovka Reservoir north of the dam to drop and raising new concerns over the already jeopardized safety of the Russian-occupied nuclear facility, Europe’s largest. The reservoir supplies water for, among other things, Zaporizhzhia’s cooling systems.

Statement from the American Nuclear Society on Zaporizhzhia nuclear power plant following dam breach

June 6, 2023, 10:02AMPress Releases

Washington, D.C. — The American Nuclear Society Rapid Response Taskforce is monitoring the impact of the breach of the Nova Kakhovka dam on the upstream Zaporizhzhia nuclear power plant in Ukraine.

Based on the best available information we believe there is enough water at Zaporizhzhia nuclear power plant to cool its six shutdown reactors, even if the downstream Nova Kakhovka dam is breached and the adjacent reservoir is drained.

As the war in Ukraine enters its second year, the International Atomic Energy Agency has released Nuclear Safety, Security and Safeguards in Ukraine, an overview of the conflict’s impact on the beleaguered nation’s nuclear facilities and of the agency’s actions to lessen the likelihood of a nuclear accident.

As if being stuck in the middle of a combat zone isn’t sufficiently nerve-racking, workers at Ukraine’s Zaporizhzhia nuclear power plant—under Russian occupation since last March—must now concern themselves with having access to enough water to keep the facility safe.

IAEA support teams sent to bolster Ukrainian power plants

In what it is calling a “major expansion” of its efforts to prevent a severe nuclear accident befalling Ukraine, the International Atomic Energy Agency yesterday announced that it is deploying teams of nuclear security and safety experts this week to the beleaguered nation’s nuclear power plants and the Chernobyl site. (The agency has already stationed a team of experts at Ukraine’s largest nuclear facility, the six-unit Zaporizhzhia plant, which has been under Russian military occupation since last March.)

Looking back at 2022—January through March

January 3, 2023, 3:00PMNuclear News

Another calendar year has passed. Before heading too far into 2023, let’s look back at what happened in 2022 for the American Nuclear Society and the nuclear community. In today's post that follows, we have compiled from Nuclear News and Nuclear Newswire what we feel are the top nuclear news stories from January through March 2022.

Stay tuned this week for the top stories from the rest of the past year.

But first, click here for some of ANS’s activities for 2022.

Russia building protection over Zaporizhzhia spent fuel tanks, according to Russian news source

Russia has begun construction of protected covering at Ukraine’s Zaporizhzhia nuclear power plant, according to a December 17 report from Russian news outlet RT. The story has been picked up in the West by some news agencies but has not been widely circulated.

Vladimir Rogov, a Russian-appointed official in Zaporizhzhia Oblast, said, “Russia is constructing a protective dome over spent radioactive fuel stores at the [Zaporizhzhia] nuclear power plant as Ukrainian forces continue to target the facility.”

Zaporizhzhia the focus of Grossi interview

December 1, 2022, 3:00PMANS Nuclear Cafe


The ongoing, tense situation surrounding the Zaporizhzhia nuclear power plant in Ukraine was the subject of a recent interview with International Atomic Energy Agency director general Rafael Mariano Grossi when he appeared on CBS's 60 Minutes program.

The Zaporizhzhia facility is in an area of Ukraine that became occupied by Russian forces in late February 2022. Though Ukrainian staff remain at the now mostly idle plant, artillery shells have repeatedly landed at and near the plant over the past several months, with Ukrainian officials—along with many Western media outlets—blaming Russia, while Russian officials and media blame Ukraine.

Action from the IAEA: Following months of negotiations with both sides, inspectors from the IAEA, led by Grossi, finally visited the site in late August and early September, and the agency has been monitoring the situation since then with an observation mission at the site. In the interview, which aired on November 20, Grossi did not attribute blame for the shelling to either side.

Four recipients awarded ANS Presidential Citations

At this year’s Winter Meeting in Phoenix, Arizona, American Nuclear Society President Steven Arndt honored four ANS members with Presidential Citations. The president of ANS has the privilege of presenting presidential citations to individuals who, in their opinion, have demonstrated outstanding effort in some manner for the benefit of ANS and/or the nuclear community.

The awards are “highlighted throughout our community as a personal outreach to our recipients to say, ‘well done,’” said Arndt.

The International Atomic Energy Agency’s board of governors has adopted a resolution calling for an immediate end to the Russian occupation of Ukraine’s Zaporizhzhia nuclear power plant. According to a report from Reuters, the 35-member board voted 26–2 yesterday in favor of the resolution, with seven abstentions. The two “no” votes were cast, unsurprisingly, by Russia and China, while abstentions came from Burundi, Egypt, India, Pakistan, Senegal, South Africa, and Vietnam.

Energoatom, Ukraine’s nuclear plant operator, is reporting that Units 5 and 6 at the Zaporizhzhia plant—currently the facility’s only operational reactors—were disconnected from the country’s power grid early in the morning of August 25.

The Zaporizhzhia site has been under the control of the Russian military since March 4, just days after Russia commenced its invasion of Ukraine.
