What is Nuclear Energy
Nuclear energy is the energy produced as a result of atomic energy where the nuclear reaction of fusion or fission takes place. Today the world uses about 17% of nuclear energy. To harness the energy, the radioactivity of the atoms is subjected to create nuclear power.
For instance, a nuclear chain reaction takes place to drive a steam turbine, where vast amounts of boiling water and heat are generated, that drives the former.
It’s megawatts of power that is produced in this process, but the opening cost of setting up a nuclear plant to use and harness this energy is very high.
Researchers and scientists believe that the solution to the world’s most top problem of global warming is nuclear energy.
France is the nation that utilizes a large amount of nuclear energy, at an estimate of 78 per cent. Lithuania follows second place with 67 per cent and the United States with 20 per cent.
Although ultimately it’s the heat that is produced from both a nuclear plant and any other power plant, it’s to be noted that the way of heat production varies between the two.
Since there’s always an energy demand whose needs keep on increasing day by day, it’s not feasible to provide them with limited amounts of fuel to satisfy their needs.
Unlike other thermal plants, this is a good source that’s made available even against the backdrop of climatic change.
Nuclear Energy Benefits
Over the next 45 years, humankind will use much more energy than it has consumed in history entirely. Earlier predictions of energy consumption evolution and growth of energy technologies proved to be wrong as consumption is increasing very faster than expected while new sources of energy aren’t likely to become commercially viable until 2035.
Moreover, fossil fuels are meanwhile growing short. Also, opportunities to create new hydropower capacity remain finite, while greenhouse effect prevention measures impose limitations on burning gas, coal and, oil at thermal power stations.
A potential response to these problems is nuclear energy, one of the fastest and youngest evolving global industries. Increasingly, having realized this, more nations are embarking on nuclear power.
The following are the benefits of nuclear energy:
1. Large capacity: One kilogram of 5%-enriched fuel grade uranium releases energy equivalent or equal to the combustion of roughly 100 tons of high-grade coal or 62 tons of oil.
2. Reusable fuel: Uranium-245 isn’t wholly burnt up in the reactor and also can be reused after reproduction (unlike slag ash remaining after fossil fuel combustion). The technology will produce zero waste, with the future transition to the closed fuel cycle,
3. Greenhouse gas reduction: speed development of nuclear energy can be regarded as a means of combating global warming. Nuclear stations decrease CO2 emissions by 750 million tons in Europe every year.
Every year, Russian nuclear stations prevent closely 205 million tons of carbon dioxide from being emitted in the atmosphere, making Russia the world’s fourth nation in terms of CO2 prevention.
4. Economic boost: In the current conditions, nuclear energy is one of the most significant sectors of Russia’s economy. Dynamic improvement of the sector is one of the basic conditions to make sure energy independence of the state, as well as the stable growth of the country’s economy.
What is Nuclear Energy Used For
The primary use of nuclear energy is the creation of electrical energy. Nuclear power plants are accountable for producing electricity. Nuclear fission reactions are created in the nuclear reactors of nuclear power plants.
What is nuclear energy – Thermal energy is obtained with these reactions that’ll be converted into mechanical energy and later transform into electrical energy.
There are other uses in which nuclear energy is used indirectly or directly. Working with variety isotopes of the same element, also you can use nuclear technology for other purposes in many fields:
- Generation of electricity: The essential and known use of nuclear energy is the production of electricity. After World War Two, the main use that was provided to nuclear energy was the creation of electric power.
Nuclear power plants are the facilities responsible for transforming the nuclear power contained in the uranium atoms into electricity. The process to obtain this conversion, However, is the result of a thermodynamic and mechanical operation.
At first, the nuclear reactor creates nuclear fission reactions that emit a massive amount of thermal energy. Steam is obtained at high pressure with all this heat energy.
The steam, thanks to its extreme pressure, drives the steam turbines of the plant. In this place, mechanical energy is obtained, the energy of rotation of an axis. The electric generator will transform the kinetic energy of the axis into electrical power.
- Uses in agriculture of nuclear technology: The application of isotopes to agriculture has enabled to escalate the agricultural production of the less developed nations.
technology is very useful in the harness of insect pests, in the improvement of crop varieties, in the high use of water resources, or in the establishment of the critical conditions to optimize the effectiveness of water and fertilizers.
- Uses of nuclear technology to food: As for food, nuclear techniques play an essential role in food production and preservation. The use of isotopes enables to escalate the conservation of food considerably. At a recent, more than 34 countries allow for irradiation of some foods.
- Environmental uses of nuclear energy: The use of isotopes enables to determine the actual amounts of contaminating substances and positions where they occur as well as their causes.
Additionally, treatment with electron beams decreases the health and environmental consequences of the large-scale use of fossil fuels, and also contributes more effectively than other techniques to solve problems like acid rain and “the greenhouse effect.”
Is Nuclear Energy Clean
What comes to mind? When you hear the words “clean energy.”
Many individuals immediately think of wind turbines or solar panels but how many people thought of nuclear energy?
Nuclear is often left out of the renewable and “clean energy” conversation despite it being the second most significant source of low-carbon electricity in the globe behind hydropower.
This new global exertion under the Clean Energy Ministerial makes sure nuclear will be considered in evolving the advanced clean energy systems of the future.
So, just how sustainable and clean is nuclear?
Try these must read facts for starters.
1. Nuclear energy system protects air quality: Nuclear is a zero-emission clean source of energy. It produces power via fission, which is the process of splitting uranium atoms to generate energy.
2. Nuclear energy’s land footprint is small: Despite generating large amounts of carbon-free power, nuclear energy creates more electricity on less land than any other clean-air source.
3. Nuclear energy creates minimal waste: Nuclear fuel is highly dense. It is about 1.2 million times greater than that of other traditional energy sources — because of this, the amount of used nuclear fuel isn’t as significant as you might think.
What is Nuclear Energy
Nuclear power is the use of sustained nuclear fission to produce electricity and heat, contributes nearly 22 per cent of the electricity created in America.
The U.S has used nuclear power for more than 65 years to generate reliable, low-carbon energy and also to support national defence activities.. As a nuclear technology, however, nuclear power can be obtained from nuclear decay, fission, and nuclear fusion reactions.
Currently, the vast majority of electricity from nuclear power is generated by nuclear fission of plutonium and Uranium. Nuclear decay processes are used in niche applications like radioisotope thermoelectric generators. Producing electricity from fusion power remains at the focus of international research.
Nuclear power is categorized as a low greenhouse gas energy supply technology, along with renewable energy, by the Intergovernmental Panel on Climate Change.
More so, Since its commercialization in the early 1970s, nuclear power has prevented about 1.85 million air pollution-related deaths and the emission of about 65 billion tonnes of carbon dioxide equivalent that would’ve otherwise resulted from the burning of fossil fuels.
What is nuclear energy – There’s a debate about nuclear power. Proponents, like the Environmentalists for Nuclear Energy and World Nuclear Association, contend that nuclear power is a safe, sustainable source of energy that decreases carbon emissions. Opponents, such as NIRS and Greenpeace argue that nuclear power poses a lot of threats to the environment and people.

How Does Nuclear Energy work
As nuclear energy is touted as a more operable and viable option for long-term energy creation, you may now ask yourself, “How does nuclear energy work?” The answer may astonish you that it’s an efficient form of energy.
What is nuclear energy – The process in which nuclear energy is generated in the result of a series of steps:
Step 1. Splitting of Atoms: Uranium atoms, in the form of ceramic-coated pellets, are positioned in a reactor core. A chain reaction is generated inside the core, which splits the atoms. However Uranium is an unstable element; by separating it, the metal becomes a variety, stable element. Radiation and heat are the byproducts generated by this process.
Step 2. Absorption: Control rods, however, are used to absorb the free-floating neurons released during the fission process. Boron released into the cooling water assists to absorb these as well. This serves to entail the radiation and keep the reactor safe and cool.
Step 3. Heat: The radiation and heat generated by the fission start to heat the water or the coolant that surrounds the reactor. However, this water serves two purposes; it keeps the reactor from becoming overheated and carrying away the steam and heat, which will power the turbines.
Step 4. Water and Piping: Water is constantly flowing around and through the reactor and serves as a coolant. Also, two sets of pipes carry this coolant out and in of the chamber. The primary pipes supply fresh water to the tank, and cold, while the secondary pipes carry away hot water and steam to the turbines.
However, once the secondary one has taken the water out of the pressurized chamber – which prevents the water from boiling, then the heated water can boil into steam and also power the turbines.
The two systems of pipes never interact with each other to keep the temperature in the chamber well balanced and to control the amount of steam and heat generated by the reactor.
Containing the Nuclear Reaction
Since the fission process creates massive amounts of radiation and heat, the nuclear reaction must be entailed at all times. This is done in several ways:
- Uranium is formed into ceramic pellets to harness the radiation.
- The pellets are packed into zirconium rods which safe and entail the fission process.
- The reactor core is surrounded by 450-tons of steel that is nine inches thick.
