Ukraine’s State Emergency Service has finally gained full control over a blaze that started February 14 after a drone struck the protective dome over the destroyed reactor from the 1986 Chernobyl nuclear plant accident.

When I graduated from Scranton University in 1956 with a B.S. in physics, I was in awe of the nuclear era and determined to be part of a nuclear future. Fortunately, I landed a position with Pratt & Whitney Aircraft as part of the Aircraft Nuclear Propulsion program. The position included a one-year assignment as a visiting staff member at Oak Ridge National Laboratory.

Social media this past weekend streamed with reactionary posts following a drone strike last Friday at the site of the destroyed reactor from the 1986 Chernobyl accident. The drone—armed with a warhead—ripped a hole in the New Safe Confinement (NSC), a large structure built to prevent any radioactive release from the damaged reactor unit 4 and to protect it from any external hazard. The drone strike caused a fire that was still smoldering in places as of Monday morning, and left a hole larger than 500 square feet. Efforts continue to mitigate the consequences of the fire and extinguish isolated smouldering areas of the NSC's insulation material.
Due to damage to the external and internal cladding of the NSC's arch and main crane system equipment, the safety boundaries and operational conditions of the NSC complex have been compromised, according to the Chernobyl nuclear power plant Facebook page.

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.
