Chernobyl: From nuclear disaster to war threat
New threat to Chernobyl.. 40 years after the explosion, the Russian-Ukrainian conflict revives the danger
Forty years after the explosion of the fourth reactor, the Chernobyl site is no longer just a memory of the worst nuclear disaster in history, but has become a meeting point between a radioactive legacy and the Russian-Ukrainian conflict. What was supposed to be a lesson from the past has become a continuous test of the present and an open threat to the future, the effects of which may extend to Europe and beyond, according to the New York Times and Washington Times.
Abandoned cities and long-lived radiation
In a joint article by Andrew E. Kramer and Evelina Riabenko, the New York Times focused on how the contaminated area remains unchanged since 1986, with dilapidated houses overgrown with plants, personal belongings left hastily by residents, and high radiation levels making return nearly impossible, especially with long-lived radioactive isotopes such as plutonium. Despite the return of wildlife to some areas, contamination remains a persistent danger.
Economic plans frozen by war
In recent years, Ukraine has attempted to exploit the region economically through projects such as nuclear waste storage, building small reactors, creating solar farms, and developing “disaster tourism.” However, the war has frozen most of these plans indefinitely.
Chernobyl a military launch point
Since the beginning of the Russian-Ukrainian conflict in February 2022, Chernobyl has gained a military dimension. Russian forces entered the region in the early days and used it as a launch point towards Kyiv. Despite their withdrawal, the area remains exposed to continuous risks, most notably landmines that hinder the work of scientists and firefighters and increase the likelihood of radiation spread in the event of fires.
Fortified zone and training ground
Chernobyl has become a closed military zone serving as a “security belt” on the border with Belarus, and is used for military training, with surface-level fortifications to avoid radiation exposure, as the war has completely changed its function. The number of deployed soldiers now exceeds the number of scientists, and security considerations take priority above all else.
Drone strike reveals containment vulnerability
In February 2025, a drone targeted the massive protective shell covering the destroyed reactor. Although no radiation leak occurred and radiation levels remained relatively stable, the strike damaged the structure designed to contain the contamination, bringing back the risk of the old “sarcophagus” collapsing.
Solar energy an exception despite war
Solar energy projects are a relative exception, as they are unaffected by radiation and can be distributed over wide areas, making them less vulnerable to attacks. Two solar power plants are operating in the region, with work continuing on a third despite the war.
Containment designed for time, not shelling
In an article by Guillaume Ptak, the Washington Times explained that the “New Safe Confinement” — a giant steel arch costing over two billion dollars and completed in 2016 — was designed to withstand time and natural factors, not wars. However, the February 2025 strike damaged vital layers responsible for sealing.
Nuclear systems designed for a different era
Inside the protective shell, there are highly hazardous materials: molten nuclear fuel, radioactive dust, and unstable debris. Any additional damage could radically change the level of danger, possibly releasing radioactive materials into the environment. The newspaper noted that the world’s nuclear safety systems were designed for a different era and did not account for modern warfare scenarios.
Warning extends to Zaporizhzhia and Europe
The same risk is repeated at the Zaporizhzhia nuclear plant, the largest in Europe, where military presence and power cuts have raised fears of a new nuclear incident. Today, the stability of the Chernobyl site depends on the course of the war, not just on engineering and technology, threatening Ukraine and possibly all of Europe.
Worst nuclear disaster in history
To understand the transformation the site has undergone after four decades, it is necessary to recall the scale of the Chernobyl disaster as an icon of nuclear danger. On April 26, 1986, reactor number 4 at the plant, located in northern Ukraine (then part of the Soviet Union), exploded due to a human error during a safety test.
