The thriving gray wolf population in the Chernobyl exclusion zone (CEZ) has been the subject of recent media interest. While some sensationalist reports have referred to “mutant wolves” with “superpowers,” other news outlets have offered more sober discussions of the science behind the story.

Cara N. Love, a biologist and postdoctoral fellow in the Department of Ecology and Evolutionary Biology at Princeton University, has been following the wolf population. Her research in the Chernobyl exclusion zone (CEZ) in Ukraine and Polesie State Radioecological Reserve in Belarus is helping biologists understand how nature adapts to chronic radiation exposure.

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.”

Space needs a few good nukes

We might actually be going back to the Moon . . . and then, on to Mars.

The Artemis program has been developed by NASA to accomplish this. Using innovative technologies, NASA will establish the first long-term human presence on the Moon, allowing a team of astronauts to explore more of the lunar surface than ever before.

With what is learned from the Artemis missions, NASA will take the next giant leap: sending the first astronauts to Mars. This goal is for scientific discovery and the economic and technological benefits that have always come from the space program, but it will also inspire a new generation of explorers: the Artemis Generation.

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.)

Countries change nuclear policies in response to Ukraine war

January 6, 2023, 7:09AMNuclear News

As a direct result of the war in Ukraine, several countries have changed their policies on nuclear energy—even those with long-standing nuclear phase-out plans. This February will mark one year since Russia began its invasion of Ukraine, leading to ongoing war and turning pandemic-era energy shortages into a global energy crisis. Spiking gas prices and concerns about electricity supply during the cold winter months have thrown many governments into a frenzy as they try to ease the impact on their citizens.

Countries in the process of phasing out their nuclear power had been prepared to increase their reliance on natural gas. But as Russia supplies 40 percent of the European Union’s natural gas, nations with no reliable alternative now face sky-high energy prices—even energy poverty. Across Europe and beyond, nuclear power plants slated for permanent closure have been given second chances to shore up energy supply. Nuclear power has also claimed a bigger spotlight in countries’ strategies for energy independence.

Four recipients awarded ANS Presidential Citations

December 1, 2022, 9:35AMANS News

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.

Freakonomics podcast focuses on nuclear energy and climate change

On a recent Freakonomics Radio podcast, host Stephen J. Dubner and his guests explored the topic of nuclear power. The episode, “Nuclear Power Isn’t Perfect. Is It Good Enough?” was teased on the podcast website with this thought: “Liberals endorse harm reduction when it comes to the opioid epidemic. Are they ready to take the same approach to climate change?”

Europe is showing renewed interest in nuclear energy “despite danger,” says the Washington Post

April 26, 2022, 7:06AMANS Nuclear Cafe

“The war in Ukraine has intensified interest across Europe in building new nuclear energy plants or extending the lives of old ones to liberate the continent from its heavy reliance on Russian oil and natural gas,” Washington Post reporters Steven Mufson and Claire Parker write in their recent article, before describing what they view as the potential dangers of nuclear energy. They also quote the American Nuclear Society in regard to the Chernobyl nuclear site in Ukraine.

Ukraine’s nuclear operator, Energoatom, announced yesterday that the Russian military has withdrawn from the Chernobyl plant and surrounding area. “According to the staff of the Chernobyl nuclear power plant, there are now no outsiders on-site,” Energoatom stated in an online post. Russian forces took control of Chernobyl on February 24, day one of the invasion.

In a separate post, the company said that the Russians had formally agreed to return the responsibility for Chernobyl to Ukraine. It shared a scan of a document, with the heading “Act of acceptance and transfer of protection of the Chernobyl nuclear plant,” purportedly signed by a representative of Russia’s National Guard, a representative of Rosatom, Russia’s state atomic energy corporation, and a Chernobyl plant shift manager.

Wars are dangerous, reactors much less so

The six reactors at the Zaporizhzhia nuclear power plant in southeastern Ukraine.

On March 4, Russian forces set fire to an office building at Ukraine’s Zaporizhzhia nuclear power plant, raising fears about reactors being damaged. The attack stirred up memories of the Chernobyl accident in 1986, a reaction that longtime nuclear opponents are taking advantage of to rekindle their cause. However, the reactors operating in Ukraine today are profoundly different from the design used at Chernobyl, and are, by nature, difficult to damage.

Let’s set the record straight and explain the risks of nuclear power plants in war zones.

Update on Ukraine

International Atomic Energy Agency director general Rafael Mariano Grossi said on Wednesday that he remains “gravely concerned” about Ukraine’s nuclear sites amid the ongoing Russian invasion and stressed the urgency of reaching an agreement on a framework that would enable his agency to provide technical assistance to ensure the safe and secure operation of those facilities.

At the press conference, Grossi explained that the IAEA has stopped receiving safeguards information from certain monitoring systems installed at Ukrainian nuclear facilities, as indicated by the red dots.

IAEA director general Rafael Mariano Grossi traveled to Antalya, Turkey, on March 10 to meet with Ukrainian foreign minister Dmytro Kuleba and Russian foreign minister Sergei Lavrov to discuss the safety and security of Ukraine's nuclear facilities. After returning to Vienna, Grossi held a press conference at which he said that a “common denominator” had emerged from the discussions and that both sides agree that something needs to be done. “They are both ready to work and to engage with the IAEA,” he said. “So this is a very important building block.”
