Theme: The Chernobyl Nuclear Power Plant (officially the Vladimir Ilyich Lenin Nuclear Power Plant)

Plans:

• Construction of Nuclear Power Plant
• Known accidents and incidents
• Chernobyl Today

Construction

• The Chernobyl Nuclear Power Plant consisted of four RBMK-1000 reactors, each capable of producing 1,000 megawatts (MW) of electric power (3,200 MW of thermal power), and the four together produced about 10% of Ukraine's electricity at the time of the disaster.

Construction of the plant and the nearby city of Pripyat to house workers and their families began in 1970, with reactor No.1 commissioned in 1977. It was the third Soviet RBMK nuclear power plant, after the Leningrad Nuclear Power and the Kursk Nuclear Power Plant, and the first plant on Ukrainian soil.

The completion of the first reactor in 1977 was followed by reactor No. 2 in 1978, No. 3 in 1981, and No. 4 in 1983. Two more blocks, numbered five and six, of more or less the same reactor design, were planned at a site roughly a kilometer from the contiguous buildings of the four older blocks.

1982 reactor #1 partial meltdown

On 9 September 1982, a partial core meltdown occurred in reactor No. 1 as a result of a faulty cooling valve remaining closed following maintenance. Once the reactor came online, the uranium in the tank overheated and ruptured. The extent of the damage was comparatively minor and no one was killed during the accident. However, due to the negligence of the operators the accident was not noticed until several hours later resulting in significant release of radiation in the form of fragments of uranium oxide and several other radioactive isotopes escaping with steam from the reactor via the ventilation stack. But the accident was not made public until several years later despite cleanups taking place in and around the power station and Pripyat. The reactor was repaired and put back into operation after eight months.

On 26 April 1986, the Chernobyl disaster occurred at reactor No. 4, caused by a catastrophic power increase resulting in core explosions and open-air fires. This caused large quantities of radioactive materials and airborne isotopes to disperse in the atmosphere and surrounding land.

• The disaster has been widely regarded as the worst accident in the history of nuclear power. As a result, Reactor No.4 was completely destroyed, and therefore enclosed in a concrete and lead sarcophagus, followed more recently by a large steel confinement shelter, to prevent further escape of radioactivity. Large areas of Europe were affected by the accident. The radioactive cloud spread as far away as Norway.

Decommissioning

After the explosion at reactor No. 4, the remaining three reactors at the power plant continued to operate, as the Soviet Union could not afford to shut the plant down. The schedule for plant decommissioning is intimately wrapped with the dismantling of reactor No.4 and the decontamination of its environs. 

What is Chernobyl like Today?

• In the hours, days, and weeks after the explosion, radioactive elements including plutonium, iodine, strontium, and caesium contaminated a region of roughly 150,000 square kilometers in Belarus, Russia and Ukraine. Carried by the wind, these elements were later detected as far away as Sweden and Finland and across the northern hemisphere. 

The region is expected to remain uninhabitable for thousands of years.

Summary!
