“The locomotive is rushing forward at great speed. Today there is still a chance to stop it, but tomorrow it might be too late.”
In the marshy flatlands and forests of the Ukraine, spring breezes arrived early that April, carrying scents of cherry blossoms. A giant nuclear electricity-generating plant with a red-and-white candy-striped smokestack stood astride the Pripyat River, ten miles north of the town of Chernobyl and nestled next to a small town, Pripyat. The station housed four 1,000-megawatt reactors, and two more reactors were under construction that, when finished, would make it the largest nuclear power plant in the Soviet Union. In the early-morning hours of Saturday, April 26, a test was getting underway at Reactor No. 4.21
The reactor core was a mammoth block of graphite 23 feet high and 38 feet in diameter, weighing 1,700 tons, honeycombed with 1,661 holes for rods filled with uranium fuel. When lowered by a crane into the holes, the fuel rods set off nuclear fission, which gave off heat, turning water into steam to power turbines generating electricity. Another 211 holes in the graphite were drilled for control rods. When lowered into the reactor, the control rods absorbed neutrons and slowed or stopped the nuclear fission. Six pumps, capable of moving up to 18.6 million gallons an hour, forced coolant water through the reactor, with two pumps in reserve. Seventeen of the Soviet RBMK-1000 reactors were built in the Soviet Union between 1973 and 1990; the RBMK acronym stood for Reaktor Bolshoi Moshchnosti Kanalnyi, or High-Power Channel Reactor. Unlike reactors in the West, such as the one at Three Mile Island, where an accident occurred in 1979, the Soviet RBMK-1000 design lacked a containment shelter, the overarching, concrete shell to hold radioactivity inside in the event of a disaster.
The rods, pumps and gears used to control and moderate the nuclear fission inside the Chernobyl reactor were dependent on electricity. If outside power were suddenly cut off, it would take forty seconds to kickstart auxiliary diesel engines. Without power for forty seconds, however, the pumps would not force water through the reactor, which would quickly overheat. This forty-second gap was something that Soviet designers knew about and worried over; they were still trying to fix it. On the night of April 26, an improvised work-around was being tested. The operators knew that after a power outage, the spinning turbine blades would keep rotating under their own momentum. So they reasoned: why not use the still-spinning blades to generate enough power to keep the water pumps going for forty seconds? The goal of the test was to see how much power the rotating blades could generate, but the duty operators were ill prepared and the reactor design badly flawed.
One operator, arriving at his station, was confused by the logbook. He called someone else to inquire.
“What shall I do?” he asked. “In the program there are instructions of what to do, and then a lot of things crossed out.”
The other person thought for a minute, then replied, “Follow the crossed out instructions.”22
After midnight Saturday, the reactor was powered down to very low levels for the test. Then, apparently because power was too low, the operators tried to power it up again, perhaps too quickly. Nuclear fission creates by-products that must be allowed to dissipate before the reactor is powered up again, but this danger was ignored.
As they powered up the reactor, a chain reaction began to spin out of control.
A foreman who entered the reactor hall at about 1:23 A.M. saw an unforgettable sight. The reactor had a massive lid. It was the “upper biological shield,” intended to prevent radiation exposure to workers during routine operations. The lid was a circle forty-nine feet in diameter, consisting of cubes, each sitting on top of a channel. When the foreman looked down, he saw the 770-pound cubes start to rumble and dance on top of the channels, “as if one thousand seven hundred people were tossing their hats into the air.”23
The operators hit the red panic button, marked “AZ,” for the emergency power reduction system. But it was too late. They desperately tried to lower the control rods to stop the fission, but the rods, by some accounts, got stuck, perhaps because the holes in the core had warped. Also, there was a design flaw in the rods, which had a section of water and graphite at each end known as the displacer, while the absorber was in the middle. When the rods got stuck, the absorber didn’t make it far enough down into the core to be useful in moderating the fission. Moreover, the rods also may have forced water out from the channels, increasing the heat and steam. In the RBMK-1000 reactor design, excessive steam caused the nuclear chain reaction to accelerate. As the heat inside the graphite core skyrocketed, more of the water then turned to steam, which caused the reactor to get even hotter. More steam, more heat, and the reactor went out of control.
At 1:23 A.M., two explosions rocked Chernobyl. These were extremely powerful, caused by the chain reaction generating huge amounts of heat and pressure. The reactor blew apart, and the explosions were followed by fire. The blast blew a hole straight upward through the roof of Reactor No. 4. The weighty lid was tossed aside like a cocked hat, and radioactive materials—gases, graphite and bits of broken fuel rods—were thrust into the atmosphere. Some debris fell down near the site. Radioactive elements were carried by the winds across Europe. The initial contamination was one nightmare, then came another: the graphite core was on fire and burned for ten days, spewing more dangerous materials into the air.
Hours after the disaster, with the graphite core burning, an “urgent report” arrived at the Central Committee in Moscow from Deputy Energy Minister Alexei Makukhin, who had once been minister of energy in the Ukraine when Chernobyl was first being built. The report said that at 1:21 A.M. on April 26 an explosion occurred in the upper part of the reactor, causing fire damage and destroying part of the roof. “At 3:30, the fire was extinguished.” Personnel at the plant were taking “measures to cool the active zone of the reactor.” No evacuation of the population was necessary, the report said.
Almost everything in Makukhin’s report was wrong. The reactor was still burning and was not being cooled, and the population should have been evacuated immediately. What the report did not say was even worse: at the scene, radiation detectors failed, firefighters and others were sent in without adequate protection and officials were debating—but not deciding—about evacuation.24
Gorbachev recalled many years later that he first heard of the disaster in a phone call at 5 A.M., but he insisted he did not learn until the evening of April 26 that the reactor had actually exploded and there had been a huge discharge into the atmosphere. “Nobody had any idea that we were facing a major nuclear disaster,” he recalled. “Quite simply, in the beginning even the top experts did not realize the gravity of the situation.”25Chernyaev, who was at Gorbachev’s side throughout the crisis, recalled that “even our top leadership did not fully realize the difficulties and dangers associated with nuclear energy.” He acknowledged that “one can blame Gorbachev for trusting those responsible,” but added, “since nuclear energy was directly linked to the military-industrial complex, it was taken for granted that everything was in perfect order. And that there was no chance of a ‘surprise’ like Chernobyl.”26
The reason for the lack of information was the Soviet system itself, which reflexively buried the truth. At each level of authority, lies were passed up and down the chain; the population was left in the dark; and scapegoats were found. Gorbachev was at the top of this decrepit system; his biggest failure was that he did not break through the pattern of cover-up right away. He reacted slowly, a moment of paralysis for this man of action. He seemed unable to get the truth when he needed it from the disaster scene or the officials responsible for nuclear power. While Gorbachev’s personal charisma had sparked excitement on the streets of Leningrad the year before, he did not appear in public for eighteen days after the explosion. While he disdained the secrecy of the military, he was just as silent before his own people and much of Europe in a situation of real peril. Gorbachev, who in January called for the elimination of all nuclear weapons, suddenly was faced with a real-
time, catastrophic example of what the world might be like after a nuclear explosion, and it was even more frightening than he could have guessed.
Without a containment shelter, radioactive isotopes soared into the atmosphere. Winds carried the contamination north, and by Sunday, radiation was detected in Sweden at the Forsmark nuclear power station, one hundred miles north of Stockholm. The Swedes confronted the Soviets at midday Monday, April 28. Gorbachev had assembled an emergency Politburo meeting at 11 A.M., but the Kremlin had not said a word about the accident, at home or abroad. In notes from the emergency meeting, aides to Gorbachev wrote: “The information was alarming but scant.”27According to Volkogonov, the historian, as the Politburo discussed how to handle the accident, Gorbachev said, “We must issue an announcement as soon as possible, we must not delay…” Alexander Yakovlev also said, “The quicker we announce it, the better it’ll be…” Other accounts suggest some Politburo members wanted to keep silent.28 The announcement was delayed for hours and hours. But people with radios that could pick up foreign broadcasts in Moscow already knew something truly horrible had happened; the reports were alarming.
Gorbachev later claimed there were two reasons for the delay: he lacked information and didn’t want to create panic. The Kremlin eventually instructed the news media to distribute a statement so terse as to relay none of the catastrophic nature of the event. The announcement was issued at 9 P.M. on April 28:
An accident has occurred at the Chernobyl Nuclear Power Plant, damaging one of the reactors. Measures are being taken to eliminate the consequences of the accident. The injured are receiving aid. A government commission has been set up.29
On the next day, April 29, Gorbachev called another Politburo meeting. According to Volkogonov, Gorbachev now realized “that he had anything but a routine problem on his hands,” given the global alarm about the accident. He began consulting with physicists and security officials. Gorbachev opened the Politburo meeting with a terse remark, “Perhaps we aren’t reacting as sharply as the states around us?” Gorbachev proposed they create an operational group to manage the crisis. He then asked, “How are we to deal with the population and international public opinion?” He paused and added a somewhat contradictory remark: “The more honestly we conduct ourselves, the better. To ensure that a shadow of suspicion should not fall on our equipment, we must say that the power station was undergoing a planned repair…”
After more discussion, the Politburo decided to issue another public statement, which Volkogonov described as “terms that might have been used to announce an ordinary fire at a warehouse.”30 The announcement said the accident had destroyed part of the reactor building, the reactor itself, and caused a degree of leakage of radioactive substances. Two people had died, the statement said, and “at the present time, the radiation situation at the power station and the vicinity has been stabilized.” One section was added for socialist countries saying that Soviet experts had noted radiation spreading in the western, northern and southern directions from Chernobyl. “Levels of contamination are somewhat higher than permitted standards, however not to the extent that calls for special measures to protect the population.”31
In the early weeks, firefighters and “liquidators,” people called from all over the country to help mitigate the disaster, fought bravely and worked with amazing courage and dedication in the face of danger. Firefighters recalled standing on a roof so hot their boots melted; helicopter pilots braved the smoldering ruins to dump 5,020 metric tons of sand and other material in an effort to suffocate what appeared to be a red glow, the burning graphite reactor below.32 But while individuals performed acts of heroism, the bosses of the Soviet state obfuscated. One of the first actions of the plant director was to cut nonessential telephone lines around Chernobyl.33 An evacuation of Pripyat was begun only thirty-six hours after the explosion; the second stage of the evacuation, including a wider zone that eventually displaced 116,000 people, did not begin until May 5. The Communist Party in Ukraine insisted that May Day parades should carry on as usual in Kiev even though winds were blowing in that direction. On May 1 in Moscow, Nikolai Ryzhkov, the prime minister, signed an instruction to take Soviet news correspondents to areas adjacent to the Chernobyl power station with a goal of preparing reports in newspapers and television showing the “normal vital activity of these areas.”34 But the truth was dawning at the highest levels in Moscow. The same instruction from Ryzhkov admitted the Health Ministry “failed” to provide full information from the scene and insisted that the ministry “take urgent measures to bring order into this affair.”
Reagan wrote in his diary, “As usual the Russians won’t put out any facts but it is evident that a radioactive cloud is spreading beyond the Soviet border.”35
Vladimir Gubarev, the science editor of Pravda, who had good contacts in the nuclear establishment, heard of the accident soon after it happened and called Yakovlev, Gorbachev’s close adviser and champion of new thinking. But Yakovlev told him to “forget about it, and stop meddling,” Gubarev recalled. Yakovlev wanted no journalists to witness the scene. But Gubarev was persistent, and kept calling Yakovlev every day. Yakovlev finally authorized a group of journalists to go to Chernobyl, including Gubarev, who had a physics degree but also wrote plays and books. He arrived May 4 and returned May 9. His private report to Yakovlev depicted chaos and confusion. One hour after the explosion, the spread of radiation was clear, he said, but no emergency measures had been prepared. “No one knew what to do.” Soldiers were sent into the danger zone without individual protective gear. They didn’t have any. Nor did helicopter pilots. “In a case like this, common sense is required, not false bravery,” he said. “The whole system of civil defense turned out to be entirely paralyzed. Even functioning dosimeters were not available.” Gubarev said, “the sluggishness of local authorities is striking. There were no clothes, shoes, or underwear for victims. They were waiting for instructions from Moscow.” In Kiev, the lack of information caused panic. People heard reports from abroad but didn’t get a single word of reassurance from the leaders of the republic. The silence created more panic in the following days when it became known that children and families of party bosses were fleeing. “A thousand people stood in line in the ticket office of the Ukraine Communist Party Central Committee,” Gubarev said. “Naturally, this was perfectly well known in the city.” When Gubarev returned to Moscow, he gave Yakovlev his written report. It was passed to Gorbachev.36
Gorbachev finally spoke about the disaster on May 14, two and a half weeks after it happened, in a nationally televised address. He looked “like a man bereaved,” recalled Angus Roxburgh, the BBC correspondent. “His face showed that he knew he had lost credibility.” His speech dodged the reasons for the catastrophe, and advanced the line that people had been alerted “as soon as we received reliable initial information.” Gorbachev seemed to lose his cool entirely at some of the wild accusations that spread in the West while the Kremlin had bottled up information, such as early reports of mass casualties in the thousands. He also took umbrage at criticism of his sincerity as a reformer. The United States and Germany “launched an unrestrained anti-Soviet campaign,” he complained.
In the weeks after Chernobyl, Gorbachev began to shake off his early inertia. At the Politburo meeting July 3, his fury boiled over at the nuclear establishment.
For 30 years you’ve been telling us that everything was safe. And you expected us to take it as the word of God. This is the root of our problems. Ministries and research centers got out of control, which led to disaster. And, so far, I do not see any signs that you’ve learned your lesson from this… Everything was kept secret from the Central Committee. Its apparat didn’t dare to look into this area. Even decisions about where to build nuclear power stations weren’t made by the leadership. Or decisions about which reactor to employ. The system was plagued by servility, bootlicking, window-dressing…persecution of critics, boasting, favoritism, and clannish management.

sp; Chernobyl happened and nobody was ready—neither civil defense, nor medical departments, not even the minimum necessary number of radiation counters. The fire brigades don’t know what to do! The next day, people were having weddings not far away from the place. Children were playing outside. The warning system is no good! There was a cloud after the explosion. Did anyone monitor its movement?37
In Gorbachev’s anger after the disaster, he did not turn the spotlight of blame on the Soviet party or the system itself. Rather, he responded by blaming individuals and finding scapegoats, including the plant operators, who were later put on trial. Gorbachev wanted to shake off the lethargy of the system, not challenge its legitimacy. Yet the inescapable truth was that Chernobyl offered a glimpse of how the Soviet Union was rotting from within. The failures, lassitude and misguided designs that led to the disaster were characteristic of much else. “The great glowing crater at Block 4 had revealed deep cracks in the state,” Volkogonov said. “After the Afghan fiasco, which Gorbachev condemned but which dragged on for another four years, Chernobyl was the next bell tolling for the system.”
Gorbachev’s emphasis on glasnost, or openness, grew significantly when he finally came to grips with what happened at Chernobyl. The word glasnost eventually became a signature of his reforms, along with perestroika, which referred to the idea of rebuilding society, politics and the economy. At the July 3 Politburo meeting, he declared, “Under no conditions will we hide the truth from the public, either in explaining the causes of the accident nor in dealing with practical issues.” He added, “We cannot be dodging the answers. Keeping things secret would hurt ourselves. Being open is a huge gain for us.” Shevardnadze’s assistant Sergei Tarasenko said Gorbachev and Shevardnadze were shamed by the way the radioactive cloud floating over Europe had revealed what they failed to announce. “For the first time, they understood that you cannot cover up anything,” Tarasenko said. “You can say, ‘Nothing happened there,’ but with radiation you cannot hide it. It will go in the air, and anyone will know it is there.”38 Shevardnadze wrote in his memoirs that Chernobyl “tore the blindfold from our eyes and persuaded us that politics and morals could not diverge.”39
