The test An inactive nuclear reactor continues to generate a significant amount of residual heat. The Chernobyl reactors used water as a coolant with reactor 4 fitted with 1, individual fuel channels; each requiring a coolant flow of 28, litres per hour.
Andrew Leatherbarrow It's been 30 years since the Chernobyl disaster, a nuclear reactor meltdown caused by a dark mix of design flaws and human error. The event immediately killed dozens and scarred the lives of tens of thousands of people over the ensuing decades. Chernobyl is still considered the worst nuclear accident in history — but it could have been much, much worse, if not for a "suicide squad" of three brave men.
Build-up to a nightmare In the early hours of April 26,a test gone awry caused two explosions that took out Chernobyl's Unit 4, killing two workers instantly and 29 more in the next four months. The long-term death count is still growing, and all estimates are disputed among scientists, government officials, and international bodies.
Together, the explosions released times as much radiation than the bomb the US dropped on Hiroshima in All fires were extinguished or contained within 6 hoursbut few anticipated a second, more dangerous problem would soon appear. In early May, Unit 4's reactor core was still melting down. Under the reactor was a huge pool of water — coolant for the power plant.
The continuous nuclear reaction, traveling in a smoldering flow of molten radioactive metal, was approaching the water. Leatherbarrow recently published a book, called "1: The Incredible True Story of the Chernobyl Nuclear Disaster ," that recounts the catastrophe's history on its 30th anniversary.
By most estimates, such a blast may have wiped out half of Europeleaving it uninhabitable foryears. The Chernobyl 'suicide squad' Andrew Leatherbarrow In order to prevent the steam explosion, workers needed to drain the pool underneath the reactor.
But the basement had flooded, and the valves were underwater. The most popular version of events then goes something like this: One soldier and two plant workers, all volunteers, bravely strapped on wetsuits and clamored into the radioactive water.
Even though their lamp died and the crew was left in darkness, they successfully shut off the valves. They knew the basement was highly radioactive, but officials promised that if they died, their families would be provided for.
It was, indeed, very possibly a suicide mission. By the time the team left the pool, this version of the story goes, they were already suffering the effects of acute radiation syndrome ARS.
All of them supposedly died within weeks. What really happened Swimming pool abandoned in the nearby town of Pripyat, Ukraine.
Andrew Leatherbarrow Leatherbarrow has spent five years researching the disaster. His book gives a slightly different, but no less heroic, version of events.
Firefighters had tried a couple of times to use specialized hoses to drain much of the basement. The three men were, according to Leatherbarrow, all plant workers — no soldiers — who happened to be on-shift when the firefighters' draining procedure stopped.
They weren't the first in the watery basement, either. Others had entered to measure the radiation levels, though Leatherbarrow said he could never discover who they were, how many had entered, or what their conclusions were.
The shift supervisor died of a heart attack in Where they are now Abandoned doll in Pripyat, Ukraine. Andrew Leatherbarrow As for the other two men, Leatherbarrow said one is still alive and working in the industry, but he hasn't released his name because of privacy concerns.
Leatherbarrow said that he lost track of the third man, but that he was alive at least up until Complicating this is the contradictory reports from English media and the Soviet government, which famously tried to downplay the disaster.
In addition, Leatherbarrow said the best sources out there have yet to be translated from Russian — including the accounts of senior managers, state-run media reports, and a book by an engineer who's been blamed for the disaster, but insists he was scapegoated by the government.
Even so, Leatherbarrow added, these men risked their lives to save untold millions of lives during a disaster of unheard of magnitude.
Like many of the workers in the hours, months, days, and even years after Chernobyl, their bravery led them to a situation that required unimaginable acts.
