CHERNOBYL

"No center of population on the earth's surface is secure from surprise destruction in a single attack. There is no defense in science against the weapon which can destroy civilization." (Gale 210) The Chernobyl disaster on April 26, 1986 is described as one of the most frightening environmental disasters in the world. The plant was made up of four graphite reactors, which were the most modern Soviet reactors of the RBMK-type. (Medvedev 4) Two more of these reactors were still under construction at the station. Chernobyl was an obscure town in north central Ukraine (former Soviet Union) on the Pripyat River near the Belarus border. (Gale 135) Immediately its name was joined to the Nuclear Power Plant located twenty-five kilometers upstream. It is not only the radioactive mess left that strikes fear, but nineteen similar stations are still running, because neither the former Soviet Union nor its republics can afford to shut them down. The world first learned of this accident from Sweden, where unusually high radiation levels were noticed at one of their own nuclear facilities. At 1:23 am technicians at the Chernobyl Plant took some erroneous actions that would impact the course of Soviet events without exaggeration.


Chernobyl has developed as an icon for the terror of uncontrolled nuclear power and abilities, and for Soviet deception and inability to provide safe conditions for workers and basic services such as transportation and health care, especially in times of greatest need. The catastrophe also halted a highly potential nuclear program. The impact of the Chernobyl Accident on a Nuclear Energy Policy is tremendous. Some countries stopped national nuclear energy programs. (Medvedev 290-307) Construction of new plants in the Soviet republics was frozen. Public opinion was directed against nuclear power plants. Some plants were even shut down, but have now been reactivated. The accident has also initiated an international activity in the area of nuclear safety and nuclear emergency planning. Many countries started a development of decision support systems for nuclear accident cases.

Multiple fires were formed both inside and out of the reactor. By five o'clock the firemen had smothered the flames. In later days, about 5000 tons of materials were thrown into the reactor well from helicopters of the air force to extinguish burning graphite and suppress radiation release. The flow of different substances continued until the beginning of June 1986. Recent data has shown only a small part of the materials actually got into the well, therefore this was not as effective as it was suppose to be. (Medvedev 26-39)

The way in which Soviet leaders have dealt with the situation is very unsettling. In the aftermath of the catastrophe several designs to encase the damaged reactor were reviewed. The option that was selected included the construction of a massive structure in concrete and steel that used what remained of the reactor walls as support. Its construction is considered one of the most complicated buildings works in the world. In charge of building the tomb was Construction Department No. 605. (Groiler 1) They ran into many problems while constructing the massive concrete and steel shell. Concrete blocks for the tomb were pieced together far from the reactor itself, and the roads entering the facilities were not accommodated for such loads, which made it difficult for the drivers. Once the blocks were delivered, the workers needed to put them in place. Each weighed several dozen tons so eventually crane operators had to perform this task. This outer protective wall, 28 stories high, is placed around the perimeter and other walls connected to the Unit 3 reactor. A steel roof then completed the structure. The destroyed reactor was entombed in a 300,000-ton concrete structure known as the "shelter" or "envelope." In conditions of high radioactivity the mammoth task was completed in seven months, in November 1986. The site around the plant had then been announced safe for about the next thirty years. However today the sarcophagus is cracked and crumbling. Some of these cracks are as
