The story of Chernobyl nuclear power plant disaster

The world's most horrible Nuclear disaster happened at Chernobyl on 26 April 1986 in the Soviet Union. The Chernobyl nuclear power station was located about 65 miles north of Kiev in Ukraine at the settlement of Pripyat. Total 32 people are died in this accident and dozens of people suffered from the radiation burns in the opening days of this crisis. Chernobyl nuclear power plant was built on the banks of the priyapt river in the late 1940s. This power plant had four nuclear reactors, each was capable for generating 1,000 megawatts of electric power. In the evening of 25 April 1986, engineers started an electrical experiment on the Number 4 reactor. The engineers whose working on that experiment had little knowledge of reactor physics, they wanted to see that, the reactor’s turbine could start emergency water pumps on inertial power.

Because of their poor knowledge of experiment, the engineers disconnected the emergency safety systems of the reactors and also power regulating system. Next, they did lots of mistakes in the experiment, They ran reactor at a very low power level and because of this mistake the reaction became unstable, and then they removed too many control rods of the reactor to power it up again. But it was increasingly difficult to control. On 26 April at 1:23 a.m. again the engineers continued their experiment and shut down the turbine engine to examine its inertial spinning would power the reactor’s water supply system. In fact, they did not provide alternative cooling source for the water pumps, and without cooling water the power level in the reactor increased.

The operators reinserted all the control rods into the reactor again to prevent meltdown. The control rods is used to reduce the reaction but had a design fault. So, before the control rod’s start to work, over 200 graphite tips entered in the reactor and causing an explosion that explode the heavy steel metal and concrete lid of the reactor. This was not a nuclear explosion, as the nuclear power stations are not capable for producing such type of reaction, but it was a chemical explosion, which created from the ignition of gases and steam. In this explosion more than 50 tons of radioactive material was released in the atmosphere, which was carried by the air currents to the long distance.

On 28 April, Swedish radiation monitoring system, which located more than 800 miles from the northwest of Chernobyl, reported the radiation levels are 40 percent higher than actual. After that day, the Soviet agency accepted that it was a major nuclear accident occurred at Chernobyl.

Over 32 people died at Chernobyl and dozens of suffered from radiation burns. The radiation spread into the atmosphere and due to this radiation, it was estimated that over 5,000 Soviet citizens are died from cancer and some other are suffered from illnesses caused by the Chernobyl radiation, and millions of peoples are health adversely affected. In 2000, the last working reactors at Chernobyl was officially closed by the Soviet Union.

Tunnel of Love - Ukraine

Tunnel of Love is a part of railway line located near Klevan, Ukraine, that connect with Orzhiv. This railway route is surrounded by three to five kilometers long lush green arches. The Tunnel of Love is amazing destination to visit in Klevan, Ukraine. This three kilometer green tunnel is a small part of railway line which leads to the fibreboard factory.

The train runs three times a day on this track and transport woods to the factory. However, the green tunnel attracts many travellers and photographers from all around the world.

It is believed that if you and your partner come into the Tunnel of Love and honestly make a wish, it will come true. It can be a new romantic place for you to explore.

The Tunnel of Love railway line runs between the arches of lush green trees. The length of this Tunnel of Love is between 3 to 5 kilometres of the total 6.4 km of track.

The train track of Tunnel of Love was firstly used in the Cold War to deliver military stuff to the nearby secret military camp and to provide adequate coverage trees were planted beside the rail line, to keep the operation remain secret.

The Tunnel of Love is most famous spot among couples, many couples come here to walk between the lush green tunnel, take some photos along the track and enjoy this natural beauty.

Everyday three or more trains may pass through the Tunnel of Love to transport loads from a nearby factory.

In this Tunnel of Love Incidents have occurred in 2015, when one Japanese women was injured after hit by a train.

The Odek plywood factory when removed some trees from the Tunnel of Love,. Many objections were taken by local people and since, that time the factory has not interfered with the trees.         

Most of people don't know about this tunnel of love until it became viral on the internet in 2011, and a publicity through social media, it has since been visited by lots of people from all over the world, and visitors have significantly increased during the past few years.
