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

Mixed/Dual Cycle – Process and its Derivation: Mixed/Dual cycle is a combination of Otto cycle and Diesel cycle, where heat addition takes place partly at constant volume and partly at constant pressure. In fact Otto cycle and Diesel cycle are special cases of Dual cycle. Both Otto cycle (constant volume heat addition) and Diesel cycle

Diesel Cycle – Definition, Process, PV Diagram and TS Diagram: Diesel Cycle was introduced by Rudolph Diesel in 1897. It is the cycle used in the Diesel (compression-ignition) engine. The heat is transferred to the working fluid at constant pressure. The Fig. 2.3 below shows the PV and T-s diagram of a Diesel cycle. The

Otto Cycle – Definition, PV Diagram and TS Diagram: It is an idealized cycle for the spark ignition internal combustion engines. It is the thermodynamic cycle most commonly found in automobile engine. Otto Cycle was conceived by Nikolaws Otto. It is the standard of comparison for internal combustion engine and a description of what happens

Waste Heat Recovery System: Waste heat recovery system is the heat which is not at all used and exhausted out as a waste product. Waste heat is normally available from the industry in the form of process steam and water at high temperature. In every type of industry, the waste heat is also discharged with
