To provide the best possible experience for you our site uses cookies.
Where are all the worlds nuclear power plants. Once you have your reactor you want to get some power out of it. This is possible only when you have the best cbse class 12 physics study material and a smart preparation plan.
Candidates who are ambitious to qualify the class 12 with good score can check this article for notes. Class 12 physics nuclear physics get here the notes for class 12 physics nuclear physics. Moderator reduces the speed of the neutron by absorbing its energy but not.
To slow down the speed fast moving neutrons produced during the fission process moderators are used. Neutrons of a fairly low speed should be used to have controlled chain reaction. The commonly used fuels are uranium plutonium or thorium moderators.
Fuel the fissionable material used in the reactor is called as fuel. This document is highly rated by class 12 students and has been viewed 3447 times. Jul 16 2020 nuclear energy fission and nuclear reactor class 12 notes edurev is made by best teachers of class 12.
A nuclear reactor formerly known as an atomic pile is a device used to initiate and control a self sustained nuclear chain reaction nuclear reactors are used at nuclear power plants for electricity generation and in nuclear marine propulsion heat from nuclear fission is passed to a working fluid water or gas which in turn runs through steam turbines.
Nuclear reactor diagram class 12. Class 12 physics chapter 13 nuclei. Nuclear reactor helps to carry out controlled chain reaction and also produce energy in sustained manner. Produced energy can be used to produce electric energy. In this article we will discuss about nuclear reactor its parts and their function.
Cbse ncert notes for class 12 physics nuclei. Nuclear reactors are useful in producing electricity. A nuclear reactor is an arrangement to generate electricity whichmakes use of nuclear fission. Nuclear reactor any of a class of devices that can initiate and control a self sustaining series of nuclear fissions.
Nuclear reactors are used as research tools as systems for producing radioactive isotope s and most prominently as energy sources for nuclear power plants. The enveloping structure that separated the nuclear reactor from the surrounding environment. A schematic representation of nuclear reactor types of nuclear reactors. Based on general use there are two types of nuclear reactor nuclear research reactors.
