The reaction that takes place in nuclear power plants and nuclear bombs is nuclear fission, which is a chain reaction. Fission is the splitting of atoms. Nuclear reactions are different from chemical reactions because they involve the nucleus, while chemical reactions only involve electrons outside the nucleus.
Which type of reaction occurs in the core of a nuclear reactor in a nuclear power plant Brainly?
The type of reaction that occurs in the core of a nuclear reactor in a power plant is the fission reaction where the nucleus of an atom is split into smaller nucleus. Along with this splitting, high amounts of energy is being produced.
What is chain reaction in nuclear power plant?
A chain reaction refers to a process in which neutrons released in fission produce an additional fission in at least one further nucleus. This nucleus in turn produces neutrons, and the process repeats. … If each neutron releases two more neutrons, then the number of fissions doubles each generation.
Why is nuclear energy bad?
Nuclear energy produces radioactive waste
A major environmental concern related to nuclear power is the creation of radioactive wastes such as uranium mill tailings, spent (used) reactor fuel, and other radioactive wastes. These materials can remain radioactive and dangerous to human health for thousands of years.
How much power does a nuclear plant produce?
Nuclear energy has been powering the U.S. grid for the past 6 decades and produces around 1 gigawatt of power per plant on average.
Is the steam from a nuclear power plant radioactive?
steam. This steam is not radioactive because it does not come into contact with the primary circuit. … The gaseous radioactive waste produced during operation of a nuclear power plant is released in a controlled way through the stacks.
Where does nuclear waste come from?
Radioactive (or nuclear) waste is a byproduct from nuclear reactors, fuel processing plants, hospitals and research facilities. Radioactive waste is also generated while decommissioning and dismantling nuclear reactors and other nuclear facilities.
Is nuclear energy clean?
Nuclear is a zero-emission clean energy source. It generates power through fission, which is the process of splitting uranium atoms to produce energy. The heat released by fission is used to create steam that spins a turbine to generate electricity without the harmful byproducts emitted by fossil fuels.
Is nuclear fusion difficult to control?
Fusion, on the other hand, is very difficult. Instead of shooting a neutron at an atom to start the process, you have to get two positively charged nuclei close enough together to get them to fuse. … This is why fusion is difficult and fission is relatively simple (but still actually difficult).
What stops a nuclear chain reaction?
The only way to control or stop a nuclear chain reaction is to stop the neutrons from splitting more atoms. … As the rods are raised, less of each rod absorbs neutrons, and the chain reaction speeds up. In this way the operators of the nuclear power plant can control and stop the nuclear chain reaction.
How do you start a nuclear reaction?
The operation of nuclear reactors is based on these reactions. By being bombarded with neutrons, nuclei with heavy atoms can be divided into several fragments formed by nuclei with lighter atoms, with neutron emission and a large release of energy. This type of nuclear reaction is called “nuclear fission reaction”.
Is it dangerous to live near a nuclear power plant?
More than 20 years after a major study said there is no evidence that people who live near nuclear power plants face an increased risk of dying from cancer, the federal government will look anew at the subject, starting with seven nuclear facilities from Connecticut to California.
Is nuclear safer than solar?
Nuclear is safer based upon actual deaths per terawatt hour and less polluting. … Solar, wind, nuclear are all much safer than coal, natural gas and oil. The fossil fuels kill with particulates and other pollution. Nuclear power did offset coal power usage.
How safe is nuclear power?
The evidence over six decades shows that nuclear power is a safe means of generating electricity. The risk of accidents in nuclear power plants is low and declining. The consequences of an accident or terrorist attack are minimal compared with other commonly accepted risks.
