核能与核安全(英文版)

For example, a coal - fired power plants with installed capacity of 1 million kw, coal consumption is 2.5 million tons a year. A nuclear power station of the same size, annual consumes 25 tons of low-enriched uranium.
Nuclear energy is the economical energy. Because the fuel cost and the transportation cost is low. As the technology is constantly improving and enhancing， nuclear power plant will also continue to lower costs. And nuclear power generation cost less affected by international economic. .situation
The consequences of the Chernobyl nuclear accident was very serious, but the accident was caused by human factors. The direct cause of the accident was due to mishandling during a test.
First, nuclear energy is a high concentrated energy, especially suitable for lack of conventional energy sources and electricity - starved region, not limited by fuel for transport。As China's southeast and south region.

The Soviet Union in 1986 of the Chernobyl Nuclear Power Plant Accident, Japan's Fukushima nuclear power plant accident in 2011, had increased people's worries.

4、 Advantages of nuclear energy
Nuclear power is concentrated, clean, safe and economical energy.
Dayawan nuclear power plant French special Likasitan nuclear power plant
Nuclear power plants now mainly uses a defense-indepth strategy, the first layer of defense is the fuel cladding
the fuel cladding
the second layer of defense is the primary circuit pressure boundary
Chain reaction
Ways of developing nuclear energy have two : one is the fission of heavy elements, such as the fission of uranium

The human development and utilization of nuclear energy is mainly developed nuclear power, relative to other forms of energy, nuclear energy has distinct advantages.
The world nuclear power distribution
In the 30 countries that now have nuclear power, the proportion of nuclear power changes greatly. Up to 80 percent from France, Belgium 52, South Korea 39, Switzerland 37, Japan 29, United States 20, South Africa 4 and China 2.
Science has shown that nuclear power on the public health impact is far less than many health risks encountered in daily life.
Comparison of radiation Around the nuclear power plant
the other is the fusion of light elements, such as deuterium, tritium, and so on
Fusion
Fission of heavy elements techniques, have been practical application, And light elements in fusion technology, is also being actively developed .
The root cause of the accident was Tokyo Electric Power Company taking into account economic factors at the beginning of the accident，refused to pump water into the reactor core.Until a week later when tried to water the Core， but the time was late because gathered a large amount of heat and radiation eventually caused the explosion.
In 1954, the former Soviet Union built an experimental nuclear power station ; in 1957, the United States had successfully built nuclear power plant.
Tokamak
2、 Use of nuclear energy
Human reality uses of nuclear energy began in the war.

China also have our own nuclear bombs, hydrogen bombs, nuclear submarines.
And after decades of development and improvement of nuclear energy, nuclear power plants has become one of the security sector. Since first nuclear power station is built, more than 400 nuclear power plants in operation around the world, but they are basically safe and normal in more than 30 years。
Besides radiotherapy is one of the applications of nuclear energy.
Nuclear magnetic resonance equipment
3、All of the nuclear concerns
We ordinary people know about nuclear power plant is basically negative. Biggest problem is the concern that nuclear power plants vulnerable to security issues.

1、What is nuclear energy
Nuclear energy is released from the nucleus through the conversion of its quality.
Nuclear reactions may be induced by bombardment with a wide variety of particles.
primary circuit Pressure boundary

In accordance with the method of determining theory and probability theory, personal risks of nuclear power plants is : Every 100 years due to reactor accidents killed 4 people, far below the traffic accident, fire, air crash, the Tornados.
the emissions from waste carbon dioxide 6.5 million tons sulfur dioxide 17,000 tons nitrogen oxides 4,000 tons coal ash 280,000 tons
5、The current nuclear security measures
1kg U
=
2700 tons of coal
Meanwhile, nuclear power is clean energy and to protect the environment. Nuclear power generation unlike fossil fuel power plants that emit huge amounts of pollutants into the atmosphere.
