Boiling Water Reactor (BWR) – Advantages and Disadvantages: In this Boiling Water reactor, enriched Uranium is used as fuel. Enriched uranium contains more fissionable isotope U235. Water is used as coolant, moderator and reflector like in PWR except the steam is generated in the reactor itself instead of separate steam boiler. Water enters the reactor …

Nuclear Reactor – Definition and its Components: Nuclear reactor is an apparatus which is used to extract the heat produced by the nuclear fission chain reaction. In other words, a nuclear reactor is a controlled chain-reacting system supplying nuclear energy. Mechanism of heat production The fission fragment after bombardment with the nucleus move at high …
Site Selection for Nuclear Power Plant: Assessment of public safety results in greater concern for site selection for a Nuclear power plant. All the natural factors are taken into account like transport of radioactive material to the public during normal operating condition as well as highly unlikely event of an accident that would result in …
Layout of Nuclear Power Plant: The layout of nuclear power plant is shown in Fig.3.4. The main components of nuclear power plant are 1. Nuclear reactor, 2. Steam generator, 3. Turbine, 4. Coolant pump & feed pump, and 5. Generator. 1. Nuclear reactor: It consists of the following components. (a) Core: This contains the nuclear …
Nuclear Fission and Nuclear chain reaction: Uranium exists in different isotopes of U238, U234 , and U235. Out of these, U235 is the most unstable. When unstable heavy nucleus is bombarded with high energy neutrons, it splits up roughly into two equal fragments and about 2.5 neutrons are released and a large amount of energy is produced …
Nuclear Reaction Equation: The Nuclear Reaction Equation are connected with the resettlement of protons and neutrons within the atom. The equations are similar to chemical reactions. The change in the mass of the particle represents the release of energy, that is if the total mass of the particle after the reaction is reduced, it has …
What is Radioactivity? – Definition and Types The phenomenon of spontaneous emission of powerful radiation exhibited by heavy elements is called radioactivity. It is an irreversible self-disintegrating activity as the elements breaks itself up (fission reaction). The elements that exhibit this activity are called radioactive elements. Example of radioactive elements are uranium, radium, thorium, pulutonium, …
Basics of Nuclear Engineering: Basics of Nuclear Engineering – A matter is composed of atoms. An atom consists of a positive charged nucleus surrounded by a number of negatively charged electrons. The atomic structures of hydrogen, Helium and oxygen are shown in Fig. 3.1. The nucleus contains protons and neutrons. The number of protons in …
Diesel Engine Power Plant – Layout, Types and Applications: Introduction: Diesel engine power plant (prime mover is a diesel engine) are installed where supply of coal and water is not available in sufficient quantity. These plants produce power in the range of 2 to 50 MW. The diesel power plants are more efficient then any …
