Why is nuclear energy not a renewable energy source?

At present, nuclear energy is the use of fissile nuclear materials, mainly uranium-235, which is a natural mineral resource, of course, it is not a renewable energy, but the energy density of nuclear materials is very high, and a large amount of energy can be obtained by using less U-235, so it has become a new energy source used to replace fossil energy.

In addition, with the development of nuclear technology, more abundant fissile nuclear materials such as uranium-238 can also be used to become new artificial nuclear materials through fission reactions, so the availability of nuclear energy resources has been greatly increased.

But at the end of the day, nuclear energy is also a finite energy source and is not renewable.

Landlord. The raw materials required for the development of nuclear energy are glaze energy.

Nowadays, there are two principles of using nuclear energy to generate electricity, one is nuclear fission and the other is nuclear fusion.

Nuclear fission, on the other hand, is more common, and nuclear fusion is being experimental.

Because of the use of glaze to generate electricity, less raw materials are required, and the glaze resources distributed in the world are more abundant.

If nuclear power plants are properly handled, nuclear power generation will not have a significant impact on the environment.

In this case, it can be considered as a cleaner energy source than fossil fuels.

Because glaze is regenerated in a short period of time to meet human needs, it is not inexhaustible, so it is classified as a category of non-renewable energy.

Nuclear energy is the energy produced by nuclear fission using radioactive materials in nature, which are natural mineral deposits, such as uranium ore, etc., which are non-renewable, so nuclear energy is not a renewable energy source.

Once the nuclear fuel has been burned once, it can no longer be used.

1) Whether nuclear energy counts as renewable: This is a controversial issue.

2) Nuclear fuel generally refers to the fissile nuclides uranium-233, uranium-235 and plutonium-239 or their mixtures. It has been calculated that a million-kilowatt nuclear power plant consumes about 235 tons of uranium 25 tons per year. Thermal power plants with the same rate consume 68.75 million tons of coal per year.

The only fissile element that exists in nature is uranium-235

And it accounts only for natural uranium.

The rest are uranium-238), but a portion of uranium-238 can be used in nuclear power plants

Converted to plutonium-239, thorium-232 (abundant in nature) to uranium-233, so the reserves of nuclear fuel can meet the needs of long-term nuclear power generation.

In addition to nuclear fission power generation, thermonuclear fusion power generation is being studied to finally solve the energy problem of mankind. Nuclear fusion can release enormous amounts of energy in an instant (such as a hydrogen bomb), and the calorific value of 1 kilogram of deuterium is equivalent to 4 kilograms of uranium-235.

3) Controlled nuclear fusion is inexhaustible, and the amount is very large, enough for human beings for tens of millions of years, or even hundreds of millions of years, which is recognized by everyone. Our country is building the world's first one in Anhui"Artificial sun"(Hefei Institute of Physical Sciences, Chinese Academy of Sciences).

4) CHZ: You can keep an eye out for reports on this!

5) I think if controlled fusion goes commercialized: then nuclear energy is renewable!! Why?

Because, the fuels used for nuclear fusion energy are deuterium (d) and tritium. Deuterium is abundant in seawater. There is about one deuterium atom for every 600 hydrogen atoms in seawater, and the total amount of deuterium in seawater is about 40 trillion tons.

The fusion energy released by the complete fusion of deuterium contained in each liter of seawater is equivalent to the energy of 300 liters of gasoline fuel. Based on the current energy consumption of the world, the fusion energy of deuterium in seawater can be used for tens of billions of years. Tritium can be manufactured with lithium.

There are two main isotopes of lithium, lithium-6 and lithium-7. After absorbing a thermal neutron, lithium-6 can turn into tritium and release energy. Lithium-7 needs to absorb fast neutrons to turn into tritium.

Although the reserves of lithium on Earth are much smaller than deuterium, there are more than 200 billion tons. It was used to make tritium, which was enough to use the era of human beings using deuterium and deuterium fusion. Therefore, nuclear fusion energy is an inexhaustible new energy source.

6) In the foreseeable time of human existence on the earth, the deuterium of water is enough to meet the energy needs of human beings for billions of years in the future. In this sense, fusion fuel on earth is infinitely abundant to meet the needs of the future, and the development of fusion energy will solve the energy needs of mankind "once and for all". Over the past 60 years, scientists have made unremitting efforts to show a bright future for humanity in this regard.

That's a very good question! Happy Chinese New Year!

Nuclear fission is not a renewable energy source because the earth's mineral resources such as uranium are very limited. Nuclear fusion can be seen as a renewable energy source to some extent, because the fusion feedstock, the isotope of hydrogen, is abundant in the ocean.

Theoretically, it is renewable.

Now people use nuclear energy mainly with the energy produced by nuclear fission, but there is another form of nuclear reaction, that is, nuclear fusion, the energy produced by this reaction is three orders of magnitude higher than nuclear fission or more, but now people have not found a way to control the conditions of nuclear fusion, and now nuclear fusion is only carried out in the laboratory. But believe that people will get to this point.

No matter what kind of reaction people use one nucleus to bombard another nucleus, the new nucleus produced in this reaction can be used as a reaction substance for another reaction, so it can be said again.

You may ask that such a reaction will violate the energy balance, but otherwise, there will be a loss of mass in this reaction, which is the problem of the mass-energy equation, and people can use atoms to get energy in this way!

Nuclear energy is certainly not a renewable energy source, and all nuclear waste from China's nuclear power plants has to go through a special route and be sent to a place for centralized burial and disposal with the help of the army and local police.

No, it's in the textbooks! The use of nuclear fission or nuclear fusion consumes nuclear energy (uranium), which is scarce!

No, after the release of nuclear energy, it cannot return to nuclear fuel on its own in the short term, that is, it is not a renewable energy source.

Nuclear energy is not considered a renewable energy source because it is obtained from uranium ore, a non-renewable resource. Uranium ore reserves are limited, so nuclear energy does not meet the definition of renewable energy. Renewable energy refers to the energy that is continuously generated in nature, such as solar energy, wind energy, hydro energy, geothermal energy, etc.

These energies are considered to be sustainable because they can be continuously regenerated and renewed, and are not depleted by use. Although nuclear energy is not a renewable energy source, it is a clean energy source that can replace the traditional fossil energy of Zhaotong to a certain extent and reduce the emission of greenhouse gases such as carbon dioxide. However, at the same time, nuclear energy also has certain safety problems and nuclear waste disposal problems, and strict measures need to be taken to ensure safety and environmental protection.

It is not nuclear energy, it is not a renewable energy, nuclear energy is a non-renewable energy source. Because nuclear fuel is a mineral resource, mineral resources are non-renewable resources. Non-renewable energy refers to energy that has been formed over hundreds of millions of years in the self-drafted energy world, cannot be restored in the short term, and with large-scale development and utilization, the reserves are getting smaller and smaller, and there is always a day of depletion.

Nuclear energy is the energy released from the nucleus through nuclear reactions, which can be released through three types of nuclear trapped chain reactions: nuclear fission, nuclear fusion, and nuclear decay.

No, nuclear energy is not a renewable energy source, but it is a clean energy source.

Compared to thermal power plants, nuclear power plants are very clean energy sources and do not emit these harmful substances"The greenhouse effect"Therefore, it can greatly improve the quality of the environment and protect the ecological environment on which human beings depend.

China is stepping up efforts to adjust its energy structure. It is urgent to actively develop clean and high-quality energy sources such as nuclear power, wind power, and hydropower. China's energy structure is still dominated by coal, and the proportion of clean and high-quality energy is low.

Nuclear Energy Costs:

Statistics from the world's nuclear power countries for many years show that although the investment in nuclear power plants is higher than that of coal-fired power plants, the total cost of electricity generation of nuclear power plants is lower than that of coal-fired power plants, because the cost of nuclear fuel is much lower than the cost of coal, on the contrary, the energy released by nuclear fuel reactions is much higher than that released by fossil fuel combustion, and nuclear fuel is inexhaustible, which makes the total power generation cost of nuclear power plants lower than that of coal-fired power plants. <>

Yes, nuclear energy is a non-renewable resource, nuclear energy is the energy released from the nucleus through the nuclear balance reaction, there are three main types of nuclear reactions, namely nuclear fission, nuclear fusion and nuclear decay, now most of us use nuclear fission energy, and the elements of nuclear fission are non-renewable. The fusion element Hydrogen 3** is in a dynamic equilibrium on Earth, and the half-life of this isotope is about years, due to decay, and the amount brought by the solar wind is in equilibrium. If it can be used, it has almost no significant impact on hydrogen 3 in nature, so it can be called a "renewable" energy fiber Zhiyou, and its regeneration is the transmission of solar wind.

According to the law of conservation of energy, tritium and deuterium collide into a larger nucleus to release a huge amount of energy, then the obtained nucleus into small pieces need to absorb a huge amount of energy, at present human beings are unable to provide such a large amount of energy to break them into small pieces, since it can't be done of course is a non-renewable resource. Destroy the locust.
