Plohi: Russia's nuclear recklessness echoes Chernobyl's flaws

  • Russia's nuclear plant takeovers revive the Soviet secrecy that caused the Chernobyl disaster.
  • Occupiers can trigger meltdowns through mismanagement, not just direct military attacks.
  • International law is unprepared for a world where reactors are front-line military assets.

The real threat to Ukraine’s nuclear plants isn't just a missile strike. It’s the political culture of the soldiers inside.

Historian Serhii Plohi argues the 1986 Chernobyl disaster was a product of Soviet secrecy, not just flawed engineering. Speaking on The Intelligence from The Economist, he explained the reactor's design was adapted from military technology for producing weapon-grade plutonium. Its quirks were classified, leaving even the operators ignorant of the machine's limits. When they hit the emergency button, it detonated.

That same political culture now occupies Zaporizhzhia. Plohi contends that modern Russia shares the Soviet instinct for hierarchy over safety and hiding responsibility. The 2022 invasion didn’t just put reactors on the front line; it reintroduced a historically catastrophic management style into Europe’s largest nuclear plant.

Russia’s actions shattered the global taboo against militarizing atomic facilities. An attack was once unthinkable; now it is a proven tactic. Plohi notes that international law is dangerously outdated, treating reactors like hydroelectric dams and leaving the International Atomic Energy Agency powerless to intervene when a state turns a plant into a fortress.

Drones have made the situation more volatile. A non-nuclear state can now trigger a nuclear event by striking a rival's cooling systems or spent fuel storage. Luck has been the main defense. A Russian drone pierced the Chernobyl sarcophagus in 2025 without a major release, but as Plohi argues, relying on luck is not a strategy.

The original Chernobyl blast stalled nuclear power's growth for a generation. Only three new reactors have been built in the U.S. in 30 years, and the Fukushima disaster prompted Germany to abandon nuclear power entirely. This new era of weaponization creates another chilling precedent.

Plohi’s warning is direct: We have no business building new reactors until a global convention protects existing ones during war. The taboo is gone, and the world is unprepared.

An explosion still echoing: Chernobyl at 40 • Apr 24

  • Chernobyl fostered international learning, with the International Atomic Energy Agency (IAEA) facilitating information exchange and leading to the modernization of Soviet-made reactors to Western standards. The realization that "Chernobyl anywhere is Chernobyl everywhere" underscored nuclear safety as an international concern.
  • In 2022, Chernobyl became the first nuclear plant occupied by an invading army, followed by Zaporizhzhia in March 2022, the largest nuclear power plant in Europe. Serhii Plohi argues that Russia demonstrated a complete disregard for nuclear safety, showing "zero learning" from the 1986 disaster.
  • There was no pre-existing protocol for the military occupation of a nuclear plant, as such an event was previously considered unthinkable. Serhii Plohi advocates for a new international convention to protect nuclear sites during wartime, as the IAEA currently lacks a mandate for such situations.
  • Chernobyl became a potent symbol of nuclear dangers, contributing to public reluctance towards nuclear power and affecting its proliferation. Jim Smith notes only three reactors have been built in the U.S. in the last 30 years, and Germany decided to go nuclear-free after Fukushima.

History (3)

  • The Chernobyl nuclear power plant explosion in April 1986 was the worst nuclear disaster in history, detonating with the force of 60 tons of TNT. The incident stemmed from a safety test where engineers overrode protocols and a less experienced night shift unexpectedly managed the test.
  • The Soviet Union inaugurated the world's first atomic power plant in 1954, sparking a nuclear power race during the Cold War. By the 1970s, the RBMK reactor design was the largest globally, praised for quick, cheap construction but known to have faults.
  • Serhii Plohi explains that the Chernobyl reactor design, stolen from the U.S. in the late 1940s, was dual-purpose, capable of producing weapon-grade materials. This military secrecy meant even operators were unaware of critical design flaws, contributing to the disaster.

Politics (1)

  • Immediately after the explosion, 115,000 people were evacuated from Pripyat and surrounding areas, with another 220,000 displaced later. The Soviet government attempted to conceal the truth, falsely attributing deaths to decrease official victim numbers.

Health (1)

  • Approximately 15,000 people are estimated to have died from radiation exposure following the accident, with about 30 workers succumbing to acute radiation sickness shortly after. Hundreds of thousands of 'liquidators' were deployed for cleanup, often with inadequate protection.

Biology (2)

  • The Chernobyl Exclusion Zone has transformed into a thriving nature reserve, with a dramatic improvement in its ecosystem since 1994, according to Jim Smith. Przewalski's horses, an endangered species, were introduced starting in 1998 and have since flourished there.
  • Radiobiologist Olena Podolyuk studies bacteria within the Chernobyl sarcophagus that thrive in highly radioactive environments. These bacteria may have evolved to use radiation as an energy source, offering insights for genetic engineering to enable survival in high-radiation conditions like space.
