The nuclear reactors are classified based on factors that include the following: 1. Nuclear reactions are processes in which one or more nuclides are produced from the collisions between two atomic nuclei or one atomic nucleus and a subatomic particle. Types of Nuclear Power Plant: Nuclear power plant are majorly classified as: (a) Boiling water reactor (BWR) (b) Pressurized water reactor (PWR) (c) Liquid metal cooled reactor (LMCR) (a) Boiling Water Reactor: In a boiling water reactor, the water acts as a coolant as well as moderator. Compact reactor core design: core size is reduced by half for same power output. The present analysis of There are many different types of nuclear reactors. The coolant is the material that passes through the core, transferring the heat from the fuel to a turbine. This type of waste is produced after nuclear fuel is burnt and removed from the nuclear reactors. Main components. This gives way to three large groups that include a series of generations: I, II, III, III+, which are the currently existing ones, and IV for the future ones. D. Boiling water reactor. Gas- cooled reactors are also discussed. ⦁ Nuclear Power Reactors: Established for the solitary purpose of producing energy and electricity. C. Molten sodium cooled reactor. Thermal-neutron reactors are the most common type of nuclear reactor, and light-water reactors are the most common type of thermal-neutron reactor. There are three facilities in the U.S. that handle low-level waste by land disposal. As for uranium based reactors, the basic classification of thorium nuclear reactors is based upon the average energy of the neutrons which cause the bulk of the fissions in the reactor core.From this point of view nuclear reactors are divided into two categories:. On the basis of Moderator used a) Water Moderator b) Heavy water Moderator c) … In the boiling water reactor the same water loop serves as moderator, coolant for the core, and steam source for the turbine.. High-level waste accounts for more than 95% of the radioactivity released in the power generation process from nuclear sources. Some nuclear reactors can operate with a mixture of plutonium and uranium (see MOX). . A “Generation IV International Forum” (GIF) was initiated in 2000. Boiling Water Reactors (BWR) and Pressurized Water Reactors (PWR). Worldwide, there are different types of nuclear reactors available. A nuclear reactor is a device in which the nuclear fission reaction takes place in a self sustained and controlled manner. The types of advanced nuclear reactors are categorized in various ways. Nowadays, nuclear reactors are classified according to the technological leap they constitute. fBreeder Reactors. Pressurized water nuclear reactors, or PWRs, are another type of light water reactors, using ordinary water as its coolant. This steam is used to power a turbine to generate electricity.
