What are the parts of a nuclear?
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.
How does a nuclear work step by step?
Nuclear power comes from nuclear fission Nuclear power plants heat water to produce steam. The steam is used to spin large turbines that generate electricity. Nuclear power plants use heat produced during nuclear fission to heat water. In nuclear fission, atoms are split apart to form smaller atoms, releasing energy.
How is nuclear produced?
Nuclear energy originates from the splitting of uranium atoms – a process called fission. This generates heat to produce steam, which is used by a turbine generator to generate electricity.
What are the 4 types of nuclear reactors?
Main types of nuclear reactor
- Pressurised water reactor (PWR)
- Boiling water reactor (BWR)
- Advanced gas-cooled reactor (AGR)
- Light water graphite-moderated reactor (LWGR)
- Fast neutron reactor (FNR)
- Operable nuclear power plants.
What are the three main sections of a nuclear power plant?
nuclear power plants
- reactor.
- generator.
- cooling towers.
Why is uranium used in bombs?
The isotopes uranium-235 and plutonium-239 were selected by the atomic scientists because they readily undergo fission.
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.
Where does uranium come from?
Uranium occurs naturally in low concentrations in soil, rock and water, and is commercially extracted from uranium-bearing minerals such as uraninite. Uranium ore can be mined from open pits or underground excavations. The ore can then be crushed and treated at a mill to separate the valuable uranium from the ore.
What is PWR and BWR?
A boiling water reactor (BWR) is a type of light water nuclear reactor used for the generation of electrical power. It is the second most common type of electricity-generating nuclear reactor after the pressurized water reactor (PWR), which is also a type of light water nuclear reactor.
