Worldwide, there are different types of nuclear reactors available. Operation at a power level of 1,500 MWth, for 6 months, followed by a scram (shut-down). A nuclear power reactor is operated according to the following power history: 1. Various types of nuclear reactor are used to generate electricity in France. In most naval reactors… Water is used as the moderator in pressurised-water reactors. Nuclear reactors have come to stay as a major source of energy for electricity generation especially in advanced nations. DIFFERENT TYPES OF NUCLEAR POWER PLANT INTRODUCTION . Six types of reactor (Magnox, AGR, PWR, BWR, CANDU and RBMK) have emerged as the designs used to produce commercial electricity around the world. The reactants are fed in to the reactor all at once initially. Based on its design, it uses Uranium with different concentrations used for fuel, moderators to delay the process of fission and coolants to heat transfer. 1. ⦁ Nuclear Power Reactors: Established for the solitary purpose of producing energy and electricity. It generates five megawatts of electricity or 15 megawatts of thermal power.
