Nuclear power is a clean, safe and mature technology with strong supply capacity and can be applied on a large scale. The application of nuclear energy in the world has experienced.
In the process of continuous improvement of nuclear power units from the first generation to the third generation, at present, the international research on the fourth generation nuclear energy utilization system has put forward new concepts of reactor design and nuclear fuel cycle scheme. China nuclear power entered the development stage from the very beginning, and has the ability to independently design and build the second generation nuclear power. China has made a major decision to actively promote the development of nuclear power, accelerate the construction of nuclear power in China, and increase the proportion of nuclear power in power supply, which will help ease the contradiction between power growth and transportation and environmental protection. The development prospect of nuclear energy utilization will be.
Keywords: nuclear energy application; Prospect; Nuclear power development
The use of nuclear energy is the only way to solve the energy problem, and it can be used in energy.
The proportion of sources will gradually increase, thus improving the energy structure, and
I hope that in the future, human demand for energy can be completely solved. In that way
However, the development and utilization of nuclear energy is a long-term and gradual process.
Cheng, according to its scientific and technological difficulty and industrialization prospect, is promising.
It can be divided into three stages: the first stage is thermal neutron reactor,
The second stage is fast breeder reactor, and the third stage is controlled fusion.
These three stages need to be interrelated and cross, and gradually enter the reality.
Use, realize industrialization.
Actively develop nuclear power, because nuclear energy has its irreplaceable conditions.
Advantages of chromatographic column:
(1) nuclear energy is the most abundant energy on the earth, and it is also
Highly concentrated energy. 1t energy generated by uranium fission,
Equivalent to 2.7 million tons of standard coal. Confirmed nuclear fission on earth
Fuel, that is, uranium ore and thorium ore resources, according to their energy content,
Equivalent to 20 times of organic fuel, as long as it is developed and utilized in time,
It has the ability to replace and follow up organic fuels. In addition, in order to
There is still a lot of fused nuclear fuel deuterium on the ball, which can be reversed by fusion.
Nuclear energy should be generated. 1t deuterium fusion produces energy equivalent to 1 100.
Ten thousand tons of standard coal, deuterium is the "heavy hydrogen" of heavy water, which is found in ordinary water.
One thousandth of heavy water, so there are about 40 trillion tons on the earth.
Deuterium Therefore, after the success of the fusion reactor, the energy was really taken away.
Endless, inexhaustible, mankind will no longer be troubled by energy problems.
(2) Nuclear power is a kind of clean energy, which is beneficial to environmental protection.
At present, the consequences of burning a lot of organic fuels in the world are worrying enough.
Yes After combustion, a lot of sulfur dioxide, carbon dioxide and oxygen are discharged.
Nitrite and other gases not only directly endanger human health and crops.
Growth has also led to acid rain and the "greenhouse effect" of the atmosphere, breaking.
Ecological balance is not good. Comparatively speaking, nuclear power plants do not have these hazards.
Nuclear power plants strictly abide by internationally recognized safety norms and health regulations.
Fan design, radioactive waste, in principle, is recycling and storage.
Saving is not good for the environment, but only after treatment and recycling.
There is little residual tail gas, which is not true to the environment.
Qualitative influence.
(3) Nuclear power plants adhere to the policy of safety first and quality first.
Nuclear power plants designed correctly, built with high quality and operated according to specifications,
Its security is guaranteed.
(4) the economy of nuclear power and the competitiveness of thermal power. Power plant every
The cost of kilowatt-hours consists of building depreciation, fuel and operating expenses.
It consists of three parts. Mainly construction depreciation and fuel costs. nucleus
The construction cost of power plants is higher than that of thermal power plants, because thermal power plants pay attention to safety and quality.
But the fuel cost is lower than that of thermal power plants, which account for about the power generation.
40% ~ 60% of the cost, while the fuel cost of nuclear power plants only accounts for.
About 2o%. Generally speaking, the power generation cost of nuclear power plants can be
Competing with thermal power.
(5) Developing nuclear power is conducive to reducing the impact of transportation system on fuel transportation.
The burden of failure. 1 coal-fired thermal power unit, daily power generation 1 10,000 kilowatts.
It needs about 1 10,000 tons of coal, and 1 year needs about 3 million tons, while it needs 1 seat.
LOOkW's nuclear power unit only needs 30 tons of nuclear fuel every year, which shows that nuclear
The fuel transportation volume is only one-hundredth of the coal transportation volume, which is greatly reduced.
The transportation burden is light.
(6) Replacing coal and oil with nuclear fuel is beneficial to resources.
Reasonable use. Coal and petroleum belong to chemical industry and textile industry.
Precious raw materials can be used to make various products. They are on the ground.
The storage on the ball is very limited; As raw materials, they are better than
Fuel alone is much more valuable. Therefore, from the rational use of capital
From the source, we should also gradually replace organic combustion with nuclear fuel.
Materials.
In a word, nuclear power is a clean, safe and mature technology.
Power generation mode with strong power supply capacity and large application scale; Let me speed up
China's nuclear power construction, increase the proportion of nuclear power in power supply, there are
Spear helps to alleviate power growth, transportation and environmental protection.
Shielding; The development of nuclear power plays an important role in promoting high-tech industries and equipment manufacturing.
Develop, promote economic growth, adjust energy structure and ensure energy.
Security and the implementation of sustainable development strategy are of great significance.
