Nuclear Energy

What is nuclear energy?
The energy generated during the combustion of oil, coal, gas and energy generated when explosives detonated called the energy generated by the chemical reaction, energy is generated by the movement of electrons orbiting nuclear. Atomic energy is the energy produced during the nuclear fission or nuclear fusion.

How nuclear energy happen?
In the atomic nucleus, the nucleons (protons or neutrons regardless), at very little distance, will attract each other very strongly. Through this link energy that protons and neutrons together in the nucleus unstable. When nuclear fission or nuclear fusion, the binding energy of the nucleus will be released called atomic energy.

Nuclear energy factory is the factory that create power and record the energy from nuclear power. However there is possibilities that accidents will happen. On 26.04.1986, the accident at Unit 4 of the Chernobyl nuclear power plant from the capital Kiev Ukrainian republics of the former USSR is about 130 meters north.
The reactor has a capacity of 3200MW using graphite as retardant and water quality thermal load is light. This is a particular type of reactor developed by Russia.
The accident occurred while testing to stop power supply from outside, to see the rotation inertia of the turbine, the generator will gain much power.
From a wide range of errors, such as operating personnel actions violated the principle of operation, making the device automatically stops the oven does not work, the priority for the completion of the test, to deviate from the plan, reactor running at low power is unstable, then violated the principle of the control rods. Therefore, the reactor power increased rapidly, overheating fuel, steam generated intense, leading to damaged pipe pressure, part of the reactor and oven building.
According to the authorities, 31 people died in this accident (which, one person died from burns while extinguishing the fire and another was missing) and 203 people hospitalized due to acute radiation exposure. Because the reactor and the building was destroyed, and so the radioactive material inside the reactor leak out. As soon as the accident occurred, around 135,000 residents within a radius of 30 km from the plant to flee.

Fixing these problems might lower the chance of  facing the accidents:
- The defects of the management system of the factory
- The functional defects of sealed radioactive materials
- Violates the principle of operation, operating personnel lack knowledge
