Urgent warning over Sarcophage Tchernobyl after new damage
The sarcophage tchernobyl is back under intense scrutiny after Greenpeace warned on Tuesday, April 14 ET, that the damaged confinement structure at the Chernobyl nuclear site in Ukraine cannot be fully restored right now. The group said the risk is especially serious if the internal enclosure were to collapse uncontrollably, because that could increase the chance of radioactive releases into the environment. The warning comes after a Russian drone perforated the modern outer confinement structure in February 2025.
What Greenpeace says is at stake
Greenpeace said the outer structure, installed in 2016 to cover the reactor that exploded in April 1986, has not regained its full confinement function even after repair work. In its public report released Tuesday, the organization said the site now carries a risk of radioactive releases if the damaged system fails further. That concern centers on the inner sarcophage tchernobyl, the steel-and-concrete enclosure built after the 1986 disaster to seal the reactor remains.
Shaun Burnie, a nuclear specialist with Greenpeace Ukraine, said the situation would be “catastrophic” if the inner enclosure were to give way, pointing to the presence of highly radioactive dust, fuel granules, and large amounts of radioactivity inside. He also said the outer confinement structure cannot be repaired at present and cannot function as intended, which leaves the site exposed to continued danger.
Officials describe the site as dangerous
Sergiy Tarakanov, director of the Chernobyl plant, said the situation is very dangerous. He warned that if a rocket struck not only the confinement structure but even 200 meters away, the external impact could resemble an earthquake. He added that the 1986 accident showed that radioactive particles do not recognize borders. The sarcophage tchernobyl remains at the center of those fears because any new failure could spread contamination beyond the site itself.
Greenpeace said dismantling unstable elements inside the inner enclosure is necessary to prevent an uncontrolled collapse. But Burnie said the work is complicated by the war, with Russian missiles still being fired over Chernobyl. Ukrainian authorities have repeatedly accused Russia of targeting the site since the 2022 invasion and of striking it in 2025, damaging the structure that protects the sarcophage tchernobyl.
Cost, context, and the road ahead
In March, Jean-Noël Barrot, France’s foreign minister, said the cost of restoring the arch of the sarcophage tchernobyl in Ukraine, damaged by a Russian drone in 2025, is around 500 million euros. The figure underlines how expensive and technically difficult the response has become while the war continues around the site. The situation also keeps the Chernobyl disaster in focus 40 years after the explosion of reactor No. 4.
For now, the immediate question is whether repair efforts can stabilize the damaged confinement system before any further strike or structural failure worsens the risk. With the sarcophage tchernobyl still vulnerable and the war ongoing, the next developments will hinge on safety work, military conditions, and whether the damaged enclosure can be kept from failing further.
Immediate reactions and next steps
Greenpeace’s warning is the clearest signal yet that the current damage has not been neutralized. The organization says the site still faces a real risk of radioactive releases, and the plant director’s remarks show that those responsible for the site view the danger as immediate. The sarcophage tchernobyl therefore remains under close watch as repair and containment questions move to the front of the crisis.
