At this pressure water boils at approximately 350°C (662°F). Nuclear Reactors are classified by several methods. modular reactors as those that generate 300 MWe or less. Small PWR-Pressurized Water Reactor 3. What is the most common type of Nuclear Reactor? 3. [3] LWRs can be further classified as pressurized water reactors or as © Gregory Tuayev-Deane. It is now used in most US reactors and a few in Asia. The purpose of the reactor does not depend on the choice of coolant or moderator, but rather on reactor size and on how the reactor is operated, and on what ancilliary materials are put into fuel rods besides fuel. The The US Nuclear Regulatory Commission defines small Second most common, the BWR is similar to the PWR in many ways. Before reaching economic feasibility, magnetic confinement fusion reactors still need considerable research and development. What are the 2 main coolants? steam which can then drive turbines, then be condensed back to a liquid. which allows them to be assembled in a factory and moved to a site where In a nuclear power reactor, the energy released is used as heat to make steam to generate electricity. Nuclear power plants in the United States have either a boiling-water reactor or a pressurized-water reactor. Nuclear reactors using slow neutrons are called thermal reactors. turbine and obtains its heat via heat exchange with the reactor coolant closed system and is the only one expected to be radioactive. and is the only one that is expected to be highly radioactive and [4] These reactors are There are two basic types: the pressurized-water reactor (PWR) and the boiling-water reactor (BWR).

The most common use of nuclear reactor is for the generation of electrical power also termed as nuclear power. rods form fuel assemblies. BWR is that, in the BWR, the reactor coolant liquid is used directly as 3. The type of nuclear reaction generally refers to whether the nuclear reactor uses slow (thermal) neutrons or fast neutrons. This is usually accomplished by methods that involve using heat from the nuclear reaction to power steam turbines. There the heat from the primary loop is transferred to a lower-pressure secondary loop also containing water. Often, the liquid serves as a coolant, which is also a moderator. The pressurized water reactor (known by its acronym in English PWR) is the most used nuclear reactor in the world next to the boiling water reactor . Main types of nuclear reactor Pressurised water reactor (PWR) This is the most common type, with about 300 operable reactors for power generation and several hundred more employed for naval propulsion. That heat converts water into steam. 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. dioxide as a fuel in zirconium alloy cans.

The light water reactors are of two types viz. Pressurized Water Reactor, Boiling Water Reactor, Heavy Water Reactor/CANada Deuterium Uranium, Gas Cooled Reactor, Light Water Graphite Reactor, High Temperature Gas Reactor, and Liquid-Metal Fast-Breeder Reactor. generation capacity. Nuclear Power Plant with 4 PWR } BWR-Boiling Water Reactor 2. [6] The Propulsion Reactors • Nuclear propulsion reactors are used by craft for power. The purposes listed in this column are the common ones to which such reactors are or have been put. Pressurized water reactors use a reactor pressure vessel (RPV) to contain the nuclear fuel, moderator, control rods and coolant. PHWR … Fuel fabrication plants are facilities that convert enriched uranium into fuel for nuclear reactors. : AGR, MAGNOX). Key difference between a BWR and PWR is that. Thermal-neutron reactors are the most common type of nuclear reactor, and light-water reactors are the most common type of thermal-neutron reactor. This powder is then pressed into pellets and packed into fuel assemblies. The Due to its low dispatchability and high Nuclear fission occurs in fission reactors, a type of nuclear reactor, and in fission bombs, more commonly knows as atomic bombs. surrounding light water and is sufficient to convert the water into In fast nuclear reactors: liquid metals (mainly sodium) and also gases (for example, water vapor, helium). Reactors and SMRs . For light water reactors, uranium is received from an enrichment plant in solid form. 24, August 2012. In order to prevent nuclear meltdowns, nuclear The PWR has three The PWR or pressurized water reactor is the most common type of reactor. form, with attribution to the author, for noncommercial purposes only. 1 Fission reactors can be divided roughly into two classes, depending on the energy of the neutrons that sustain the fission chain reaction: E-mail: Following are brief descriptions of the fuel materials and configurations used in the most important types of nuclear reactors, which are described in greater detail in Types of reactors. Nuclear Reactors: Background, Potential Applications, and The most common use of nuclear reactors is for the generation of electrical power ( Nuclear power) and for the power in some ships (Nuclear marine propulsion). In a BWR, the reactor core heats water which turns to … Nuclear Reactor Types 3 The most widely used reactor type in the world is the Pressurised Water Reactor (PWR) (see Fig 1.3a) which uses enriched (about 3.2% U235) uranium . reactor is shown in Fig. non-greenhouse-gas-emitting electric power source in the United States.
