Nowadays, energy sources from conventional fuels are increasingly depleted and causing great environmental pollution. The need for a cleaner and more abundant energy source is inevitable. Nuclear energy is the number one alternative solution at this time.
The question is: Is nuclear energy renewable?? GREEN IN will help you answer this question and learn more about this special type of energy through the article below!
1. What is nuclear energy?
“Nuclear energy is the useful energy from atomic nuclei obtained by controlled nuclear reactors. There are three types of nuclear reactions: fission, fusion, and radioactive decay. Of these, fission is the most widely used because of its efficiency.”- According to Nationalgrid
For more than half a century, the power of the atom has been at the heart of generating electricity. Today, nuclear fusion is sure to power the clean energy systems of the future. What’s more, the process of using nuclear energy to generate electricity has zero net emissions globally.
2. History of nuclear energy
According to the history of nuclear energy, the first nuclear reactors began production in the early 1950s. And nuclear energy has been recognized as part of the global energy mix.
From its heyday in the 1960s to the late 1980s, the popularity of nuclear power rose and fell – and was often a source of controversy.
Today, it plays a key role in supporting clean, low-carbon electricity supply and could play a key role in efforts to achieve net-zero emissions by 0.
3. How does nuclear energy work?
Nuclear power plants work in much the same way as coal or gas-fired power plants. However, the technology behind the process is much more complex and advanced.
Nuclear reactions are driven by the splitting of atoms in nuclear reactors. Nuclear fission occurs when a nucleus is fired at an atom, causing it to split into two. These two atoms are smaller than the original atom (and may have some extra neutrons).
At this point, a chain reaction will occur with the neutrons. The neutrons will be released and collide with other atoms, causing them to split and release more neutrons. The whole process above creates heat mass.
Finally, the heat from the reactor will be transferred to the water. This reaction turns the water into pressurized steam. Through the turbines, the pressurized steam will be released. The heat energy of the steam will be converted into kinetic energy. This source of power makes the machine rotate to generate electricity to produce electricity.
4. Advantages and disadvantages of nuclear energy
Advantages of nuclear energy:
Emits little (or sometimes no) toxic gases and greenhouse gases.
Does not pollute the environment or cause harm to humans.
No need to use precious raw materials in production.
Affordable, increasingly advanced technology.
Produces energy efficiently.
Very little waste to the environment.
Provides large amounts of energy but requires little fuel.
Disadvantages of nuclear energy:
Community opposition.
Safety issues in energy production.
Occupational accidents are likely to occur during the production process.
The cost is very high if not optimized in factory construction.
Environmental sanitation is not guaranteed when excavating and refining Uranium.
Poor handling of nuclear waste transportation.
The average lifespan of a nuclear reactor is only 60 years.
5. Is nuclear energy renewable?
This is a very difficult question to answer. The world is currently divided into two different opinions. Each opinion has its own arguments, so it is difficult to come to a conclusion.
Those who argue that there are no carbon emissions in nuclear reactors. These are the people who claim that nuclear energy is renewable. They also argue that the amount of waste produced during the production process is manageable (meaning it can be reused).
According to research, nuclear energy production does not directly cause any carbon emissions. It is also proven to be a very low carbon energy source (second in the world, after hydropower). In addition, the waste from nuclear energy production is very small, much smaller than the waste from fossil fuel production.
All of the above arguments are also based on the potential of uranium production. The amount of uranium available that has been extracted and stored can be used for another 1000 years. Not only that, experts also measure that the actual amount of uranium is much larger.
In the future, when science is more and more developed, the amount of uranium will not be a concern for billions of years. That means we can use nuclear energy for billions of years.
On the other hand, there are also people who believe that nuclear energy is not renewable. Because they think that we cannot exploit all the uranium on this planet. They think that science in the future will not be able to do that, so nuclear energy is finite. They also think that the waste from nuclear energy production, although small, can cause many environmental safety problems. In particular, because the half-life of Uranium-235 (the most common nuclear fuel) is in the range of millions of years when it cannot be recycled.
In conclusion, whether nuclear energy is renewable or not depends entirely on whether uranium is finite or infinite. We need to wait for the future to answer this question, to see if scientific progress can make uranium infinite or not.
6. The combination of nuclear energy and renewable energy
In 2021, RTE announced measures to achieve carbon neutrality by 2050. In the same year, COP26 was held in Glasgow with the participation of nearly 200 countries. The event message: “We must divest from fossil fuels and reduce greenhouse gas emissions to limit global warming to +1,5°C”
Currently, the global climate is very alarming, to improve this situation, low-carbon energy production is needed. It is predicted that by 2050, the global energy demand will double. Renewable energy has many advantages, but these types of energy cannot solve all the needs of the global population.
Therefore, combining renewable energy and nuclear energy is really necessary if we want to move forward.
