The Chernobyl nuclear power them. V. I. Lenin-the Ukrainian nuclear power plant stopped its work in connection with the explosion at unit # 4. Its construction began in the spring of 1970, and 7 years later she was commissioned. By 1986, the station consisted of four blocks, which added two more. When exploded Chernobyl, or rather, one of the reactors, its operation is not stopped. Currently, the construction of the sarcophagus, which will be completed by 2015.

Station details

1970-1981. – this time was built six units, two of which did not have time to run until 1986 For cooling turbines and heat exchangers between the river Pripyat and Chernobyl were built liquid pond.

Before the accident generating station capacity was 6,000 MW. Currently, work is underway to transform Chernobyl into an environmentally safe construction.

Start of construction

To select a suitable site for the construction of the first nuclear power station design Institute of the capital of Ukraine examined the Kiev, Zhytomyr and Vinnytsia region. The most convenient place was the territory on the right side of the Pripyat river. The land on which soon began construction, was unproductive, but the requirements for the maintenance of the nuclear power station full compliance. The site was approved by gostekhkomissii of the USSR and the Ministry of energy of Ukraine.

Why exploded Chernobyl NPP

February 1970 marked the beginning of construction of Pripyat. The city was created specifically for engineers. The fact that the first years service station staff had to live in hostels and rented houses close to Chernobyl villages. For the job security of members of their families in Pripyat was built a variety of enterprises. Thus, for 16 years existence of the city it was equipped with everything necessary for comfortable living people.

The 1986 Accident

01:23 the night of 26 April 1986, there was developed the design test of the turbine of the 4th unit, which exploded Chernobyl nuclear power plant. As a result, the building collapsed, there was more than 30 fires. The first victims were V. Hodemchuk - operator circulation pumps, and V. Shashenok-employee start-up company.

In a minute after the incident, the duty for the protection of the ChNPP was informed about the explosion. Promptly to the station the firefighters arrived. Head of liquidation was appointed V. Pravik. Thanks to skillful actions had stopped the spread of the fire.

When exploded Chernobyl NPP

When exploded Chernobyl nuclear power plant, the environment was contaminated by radioactive substances such as:

- plutonium, uranium, iodine-131 (half-life lasts about 8 days);

- cesium-134 (half-life – 2 years);

- cesium-137 (from 17 to 30 years);

- strontium-90 (28 years).

The horror of the tragedy lies in the fact that the residents of Pripyat, Chernobyl and the former Soviet Union for a long time concealed the cause of the explosion of the Chernobyl nuclear power plant and who's to blame.

Accident

25 on April 4-th reactor had to be stopped for the next fixation but instead decided to test. It was to create an emergency situation in which the station itself would have coped with the problem. Such cases by that time there were already four, but this time something went wrong...

The First and main reason for the explosion of the Chernobyl nuclear power plant – it's careless and unprofessional attitude of the staff to a risky experiment. Workers supported the unit capacity by 200 MW, which led to self-poisoning.

As if nothing had happened, the staff watched the scene, rather than withdraw control rods from the work and press the button A3-5 for the emergency plugging of the reactor. As a result of inaction in the power unit began an uncontrolled chain reaction which blew up the Chernobyl nuclear power plant.

the cause of the explosion of the Chernobyl nuclear power plant

By evening (about 20.00) in the Central hall took place over an intense fire. To extinguish the fire people this time not attracted. It was eliminated with the help of helicopters.

For all the time, except firefighters and plant personnel in rescue operations were involved in about 600 thousand people.

What blew up Chernobyl? There are several reasons that contributed to this:

- the experiment was to be carried out at any cost, despite the sharp change in the behavior of the reactor;

- decommissioning work process protections that would be produced by the stop unit and prevent the accident;

- the silence of the leadership of the station of the scale of the disaster occurred and the reasons, from-for what blew up Chernobyl.

Consequences

In the aftermath of the spread of radioactive substances from the 134 firefighters and station staff developed radiation sickness, 28 of them died within a month after the accident.

Signs of exposure was vomiting and weakness. First aid was given by medical staff at the station, and after that the victims were transported to a hospital in Moscow.

The cost of his own life, the rescuers did not allow the transition of the fire to the third block. This helped to avoid the spread of fire in neighboring blocks. If the extinguishing is not successful, a second explosion could exceed the capacity of the first 10 times!

Accident of 9 September 1982

Until that day, he exploded Chernobyl nuclear power plant, was the destruction of the unit 1. During a test run of one of the reactors at a power of 700 MW has been a kind of explosion of the fuel Assembly and channel No. 62-44. This resulted in deformation of the graphite stack and the release of significant amounts of radioactive substances.

That explains why the exploded Chernobyl nuclear power plant in 1982, is the following:

- gross violations of the personnel Department in the regulation of water flow in channels;

- balance the internal stresses in the walls of the channel zirconium tubes, resulting from the changes in the technology of the factory that produced it.

The Soviet Government, as usual, decided not to inform the population why the exploded Chernobyl nuclear power plant. Photos of the first accident was not preserved. It is even possible that it never existed.

The station

Next, the article presents the names of employees and their posts before, during and after the tragedy. As the Director of the station in 1986 was Bryukhanov, Viktor Petrovich. Two months later, became the Manager Pozdyshev E. N.

Sorokin N. M. he was Deputy engineer for maintenance in the period 1987-1994 Gramotkin, I. I. from 1988 to 1995 he held the post of head of the reactor Department. Currently, he is CEO of GSP "Chernobyl".

Dyatlov Anatoly Stepanovich-Deputy chief engineer for maintenance and one of those responsible for the accident. The cause of the explosion of the Chernobyl nuclear power plant was to conduct a risky experience, which was headed by the engineer.

Exclusion Zone at the present time

The long-Suffering young Pripyat today is contaminated with radioactive substances. They are going to most often in soil, houses, ditches and other depressions. In the city of existing facilities remained the only station for water fluoridation, special Laundry, CAT and garage equipment. After the accident, Pripyat, oddly enough, have not lost the status of a city.

Exploded Chernobyl NPP

With Chernobyl, the situation is quite different. It is safe for life, live in it people in charge of the station, and so-called squatters. The city today – the administration centre of the exclusion zone. Chernobyl amalgamate the businesses that support the surrounding area in an environmentally-safe condition. Stabilization of the position is to monitor radionuclides in the Pripyat river and the air. The city is the personnel of the Ministry of internal Affairs of Ukraine, which carries out the protection and exclusion zones from illegal intrusion.
