What is a nuclear power plant and how does it work?
What do you mean by nuclear power plant?
A nuclear power plant is a facility that converts atomic energy into usable power. In a nuclear electric power plant, heat produced by a reactor is generally used to drive a turbine which in turn drives an electric generator.Jul 31, 2002
What is the importance of nuclear power plant?
Nuclear is the largest source of clean power in the United States. It generates nearly 800 billion kilowatt hours of electricity each year and produces more than half of the nation's emissions-free electricity.Mar 29, 2021
Why are nuclear power plants near water?
Most nuclear power plants are located along lakes, rivers or seacoasts because the facilities use water to cool the reactors. Cooling water discharged from a plant can affect the ambient habitat conditions for aquatic species.Dec 16, 2020
What do you mean nuclear?
1 : of, relating to, or being a nucleus (as of a cell) 2 : of or relating to the nucleus of the atom Fission is a nuclear reaction. 3 : produced by a nuclear reaction nuclear energy. 4 : of, relating to, or being a weapon whose destructive power comes from an uncontrolled nuclear reaction.
What is nuclear energy Class 10?
A physical reaction which involves changes in the nucleus of an atom is called a nuclear reaction. The energy released during a nuclear reaction is called nuclear energy (because it comes from the nucleus of an atom). Nuclear energy can be obtained by two types of nuclear reactions: (i) Nuclear fission, and.Mar 20, 2019
What is the main function of moderator?
Moderator: Moderator is a material used in a nuclear reactor to slow down the neutrons produced from fission. By slowing the neutrons down the probability of a neutron interacting with Uranium-235 nuclei is greatly increased thereby maintaining the chain reaction.
What are the 5 main components of a nuclear power plant?
Any nuclear reactor that produces power via the fission of uranium (U-235) or plutonium (Pu-239) by bombardment with neutrons must have at least five components: nuclear fuel consisting of fissionable material, a nuclear moderator, reactor coolant, control rods, and a shield/containment system.Jan 23, 2021
What is the most important part of a nuclear power plant?
Steel vessel that houses the nuclear reactor, the main component of the nuclear power plant where the fission chain reactor is produced. Its nucleus is composed of the fuel elements.
What are nuclear power plants made of?
Reactors use uranium for nuclear fuel. The uranium is processed into small ceramic pellets and stacked together into sealed metal tubes called fuel rods. Typically more than 200 of these rods are bundled together to form a fuel assembly.Mar 29, 2021

How does nuclear power affect the environment?
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.Jan 15, 2020

How much electricity does a typical nuclear power plant generate?
- A typical nuclear power plant has a generating capacity of approximately one gigawatt (GW; one billion watts) of electricity. At this capacity, a power plant that operates about 90 percent of the time (the U.S. industry average) will generate about eight terawatt-hours of electricity per year.

What are the disadvantages of a nuclear power plant?
- Disadvantages: Initial cost to set up nuclear power plant is higher as compared to hydro or steam power plant. Nuclear power plants are not well suited for varying load conditions. Radioactive wastes if not disposed carefully may have an effect on the health of operators and the population nearby. Maintenance cost of the nuclear power plant is high.

What does a nuclear power plant need to produce electricity?
- The only difference is that “chain reaction” is used to produce the heat. Nuclear power plants use nuclear fission to produce electricity. A nuclear power reactor uses uranium rods as nuclear fuel to generate heat that will be used to generate electricity.
