What they triggered instead was the beginning of the worst civilian nuclear accident in human history.
In seconds, the unstable RBMK-1000 reactor—mortally wounded by a disastrous circus of operator violations and a fatally clever design—roared past one hundred times its rated thermal output. Roughly 2,000 tons of radioactive steam, vaporized fuel, and red-hot graphite blasted skyward. As journalist Adam Higginbotham put it in his award-winning Midnight in Chernobyl, by the moment the test commenced the technicians had effectively created a pistol with a cocked hammer. All that remained was for someone to pull the trigger.
This Sunday, April 26, 2026, marks the 40th anniversary of what happened when that nuclear trigger was pulled.
For me this is not an academic exercise. My long-time friend Victor Kubik, founder of LifeNets, traveled to Pripyat (the then-all-new privileged city built from scratch to support the construction and operation of the Chernobyl power plant) and the first Chernobyl sarcophagus with an Indianapolis delegation in 2003. As a former technology columnist I have long been interested in matters of nuclear development. I joined Victor recently on his Kubik Report podcast to talk about what really destroyed Reactor No. 4.
The technical answers to the disaster are sobering. But as we jointly explored, the spiritual answers are more sobering still.
Following is a summary of our 40-minute discussion.
Chernobyl – a fatally flawed reactor
Why was the explosion so powerful, with the radioactive deadly plume showering DNA-busting debris across Europe? The RBMK-1000 was a graphite-moderated, water-cooled colossus—unique on the planet. No other nation ever paired graphite with water in a commercial power reactor because the design is prone to produce what physicists call a positive void coefficient: when the cooling water flashes to steam (and loses its ability to cool and moderate the white-hot fuel rods), the chain reaction speeds up instead of slowing down. U.S. light-water reactors are forbidden by law to operate that way.
Worse still, the RBMK’s emergency shutdown rods were tipped with graphite displacers. When the AZ-5 button was pressed at 01:23:45, those graphite tips entered the core first, actually accelerating the reaction before the boron-carbide absorbers could choke it off.
Within three seconds the runaway surge ruptured fuel channels, jamming the rods at one-third insertion. The confined inferno of steam savagely tore through all safety features, fashioning a radioactive conflagration that blasted through the roof. The 1,000-ton upper biological shield — the operators had nicknamed it “Elena” — was hurled into the air like a city manhole cover.
As tons of vaporized radioactive fuel, graphite and building materials hurtled toward the stratosphere, the wounded reactor core now lay open to the sky. Lethal ionizing radiation–known as Cherenkov radiation–burned a blue beam heavenward signaling unthinkable catastrophe.
Unlike nuclear reactors in the United States (e.g. Three Mile Island), there was no containment building. Soviet authorities had arrogantly insisted their reactors—together with their “superior design””–did not need one.
The Era of Stagnation comes due
These society-changing pathologies did not appear in a vacuum. The RBMK was a creature of the Brezhnev Era of Stagnation—when planners ruthlessly cheapened civilian nuclear designs to match American electricity output. Unrestrained by civilized norms and moral values, the very core of Soviet society began to cave in on itself in the 1960s and 1970s, and together with it the design of safety-first nuclear reactors.
Worse, the whole nuclear program was overseen by Sredmash, the Ministry of Medium Machine Building: a secretive bureaucracy that also designed Soviet atomic weapons. Inside that closed culture, dissent was career suicide. Appallingly, Soviet scientists at the Kurchatov Institute knew about the positive void coefficient as early as the 1970s. Valery Legasov, the Kurchatov deputy director who later testified before the IAEA, tragically took his own life in 1988 after concluding that nothing he said about safety would change anything.
The technical failures rode on top of a corrupt economy and society. Higginbotham grimly documents how steel, concrete, and shielding destined for Chernobyl were skimmed off and sold on the black market — entire shipments of critical parts had to be returned because the parts no longer fit the holes drilled for them. Victor saw this legacy with his own eyes when LifeNets began partnering with Dr. Vasyl Pasichnyk in 1996.
Dr. Pasichnyk, a pediatrician in Chernihiv—about 35 miles east of the doomed plant—was shocked to see children coming to him with inexplicable symptoms of radiation exposure. When he suggested to local officials that they must begin distributing emergency iodine to ward off later thyroid cancer or disease (radioactive iodine is absorbed by the human thyroid gland), Soviet officials had told him to deny the possibility that any nuclear accident had taken place.
He was further warned of consequences should he not comply. When he reported off-the-scale Geiger readings to city authorities, they ordered him to recalibrate his Geiger counter.
Dr. Pasichnyk and his physician wife Natasha courageously defied the gag order, distributing iodine and treating children.
The hidden Positive Void Coefficient — a moral one
Here is where the story turns. Higginbotham makes a point secular commentators usually skip past: the deeper engine of the disaster was not metallurgy. It was moral decay.
Three generations of Soviet citizens had been formally taught that there is no God, no spiritual engagement, no eternal accountability — that the Ten Commandments were superstition fit only to be wiped from public life. By 1986, lying had become an unremarkable feature of daily existence.
As Victor put it on our podcast, recalling his own visit to Moscow in July some three months after the accident: “To the Communists, lying isn’t irregular. Everybody knows you’re lying. They know you’re lying. But you don’t care.”
What’s the ultimate outcome? A society that has erased “Thou shalt not steal” produces black-market shielding. A society that has erased “Thou shalt not bear false witness” produces operators who falsify reactor logs and managers who tell physicians their instruments must be wrong. Corrupt government leaders model moral aberrations that reverberate to the very core of their citizens.
The critical point? A society that has banished the fear of God—and of consequences of abandoning reverential trust and obedience—will, sooner or later, build a Chernobyl.
To celebrate Chernobyl’s then-status as one of the largest performing producers of Soviet energy, Pripyat’s planners had even erected a six-meter bronze statue at the city entrance: not a Christian symbol, but of Prometheus, the mythological Greek titan who stole society-changing fire from the gods and gave it to humanity, a forbidden act. The intended conceptual message—Soviet Man harnessing the atom—proved truer than the artists knew.
Why? In the original myth, Zeus chains Prometheus to a rock to suffer daily punishment by an eagle ripping into his side. Meanwhile, Zeus punished humanity for the theft by deceptively sending a closed attractive box from Pandora, knowing that humans would be unable to resist opening it. Once opened—like the consequences of the Chernobyl disaster–the mythical Pandora’s box unleashed of host of evils that would afflict humans with misery and disease.
The cleanup that broke a nation
What followed was an act of grim courage on a staggering scale. Roughly 600,000 “liquidators”—soldiers, miners, pilots, firefighters—were rotated through the zone. Coal miners from Donetsk dug tunnels beneath the molten core with hand tools because pneumatic drills might have collapsed the foundation.
Helicopter pilots dumped sand, lead, and boron into the open reactor maw through radiation fields so intense that one approaching armored vehicle’s electronics failed before the crew could complete its assessment. Many liquidators were made to sign documents minimizing their exposure. Many later died of gruesome radiation burns or cancer.
For years the Soviet state denied that the surge in thyroid cancers—the cancers Dr. Pasichnyk catalogued in teenage girls—had any connection to Chernobyl’s deadly plume.
When Victor walked through Kiev in 1996, the city had posted micro-roentgen readings beside the usual time-and-temperature signs. A year later they were gone. Officials had decided the readings were “bad for morale.”
A positive void coefficient of the spirit
Forty years later, seven RBMK reactors still operate in Russia—retrofitted and ostensibly improved, but with the same architecture that cantharophily exploded at 01:23:45. Extracting a grim human cost, a hastily-poured sarcophagus over Reactor 4 staunched the radioactive flame and uncontrolled contamination. This hasty shield was augmented and replaced in 2016 by a $2.1 billion arch, the New Safe Confinement.
In an insane move nearly four decades later in February 2025, a Russian Shahed drone blasted a six-meter hole in its outer shell. The IAEA confirmed last December that the structure has lost its primary safety function. One humanitarian organization warned earlier in April 2026 of a possible catastrophic collapse of the original sarcophagus underneath, which still contains roughly 200 tons of active molten fuel.
What lessons can we learn?
We keep returning to that phrase — positive void coefficient. Inside a reactor it means this: as the coolant loses its life-saving capacity, the danger feeds itself.
What is the strategic essence that guides a civilization and prevents a devastating meltdown? Consider this solution: the moral law that God Himself wrote with His own finger on stone — Thou shalt not steal. Thou shalt not bear false witness. Thou shalt not covet. When a society vaporizes that essence in its own positive void coefficient, the chain reaction does not slow. It quickly accelerates to dangerous, even societally fatal levels.
The Bible–the Word of God–serves up many examples of this very tragedy, both national and personal.
Despite all corruption at the highest levels across the earth, God remains in authoritative control, working out his purpose on the planet.
God can be found
Encouragingly, a growing number of Generation Z are now asking whether the world they inherited makes any sense without a higher reference point. They are—as are we–right to ask. As David instructed his son Solomon, we are instructed to “acknowledge the God of your father, and serve him with wholehearted devotion and with a willing mind, for the Lord searches every heart and understands every desire and every thought. If you seek him, he will be found by you” (1 Chronicles 28:9, New International Version)
Consider the society-destroying focus that enabled Chernobyl. Concerned about a positive void coefficient growing in your life? Here’s a thought for looking forward and all that it means: “Set your minds on things that are above, not on things that are on earth” (Colossians 3:2, ESV).
Forty years after Chernobyl, that is not a sentimental verse. It is instruction for survival.
