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.)

The director general of the International Atomic Energy Agency, Rafael Mariano Grossi, led a mission to Ukraine’s Chernobyl nuclear plant this week to address ongoing radiological safety concerns at the shuttered site following five weeks (February 24–March 31) of Russian military occupation.

On the 36th anniversary of the Chernobyl nuclear accident, the American Nuclear Society held the webinar, “A Reactor Physicist’s Explanation of Chernobyl,” led by Christopher Perfetti, an assistant professor in the Nuclear Engineering Department at the University of New Mexico. (Here we use the more common Russian spelling of Chernobyl, rather than the Ukrainian spelling, Chornobyl.)

Ukraine’s nuclear operator, Energoatom, announced yesterday that the Russian military has withdrawn from the Chernobyl plant and surrounding area.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.

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.

External power supplies were restored to the decommissioning Chernobyl facility following repairs of damaged power lines — before being reportedly damaged again, according to Ukraine's transmission system operator Ukrenergo.
