Nuclear reactor: S work by using

Nuclear reactors work by using the heat energy released from splitting atoms of certain elements to generate electricity. Most nuclear electricity is generated using just two kinds of reactor which were developed in the 1950s and improved since. The first generation of these reactors have all been retired, and most of those operating are second-generation. New designs are coming forward, both large and small. About 9% of the world's electricity is produced from nuclear energy. This page is ... nuclear reactor , any of a class of devices that can initiate and control a self-sustaining series of nuclear fission s. Nuclear reactors are used as research tools, as systems for producing radioactive isotope s, and most prominently as energy sources for nuclear power plants. Introduction to Nuclear Reactor Before we start with the nuclear reactor , a basic understanding of nuclear fission is necessary. Nuclear fission is the process where the nucleus of a heavy atom splits into fragments of lighter nuclei. This process gives out energy. One of the ways to achieve this is to bombard the nucleus of heavy atoms with neutrinos. Along with producing energy (in terms of the ‘missing mass’), the reaction also produces neutrons. These neutrons can be used to split ... What is Nuclear Reactor ? The nuclear reactor (or atomic reactor ) is a furnace in which energy is produced by the nuclear fission process.
