![]() ![]() The difference between pressurized water reactor and boiling water reactor is that the water in a pressurized water reactor is not vaporized through boiling, but rather by th e action of a steam generator. In PWRs, water usually serves as the coolant fluid that transfers heat. Pressurized water reactor is the most commonly used type of nuclear reactor, and this is as a result of its relatively simple and effective design. The steam generator itself works by a continuous cycling of heat-transfer r ing and heat-absorbing fluids where the heat-transfer r ing fluid flows in the primary coolant loop and helps vaporize the pressurized water which is the heat-absorbing fluid in the secondary coolant loop. Pressurized water reactor works by maintaining high pressure within the vessel that prevents heated water from vaporizing, so that the water is vaporized in a steam generator by action of a primary coolant loop, and the steam is then channeled to a turbine for electricity generation. )Ī pressurized water reactor is a type of nuclear reactor in which pure water is heated by nuclear fission, and delivered to a steam generator under high pressure, in order to generate electricity. Types of Nuclear Reactors: Boiling Water Reactor (BWR) (Credit: Σ64 2020. Boiling water reactors are also associated with high cost and high maintenance requirements. The main disadvantage of a boiling water reactor is its efficiency, which hovers around 30% under practical conditions. The amount of energy a boiling water reactor produces depends on its capacity and scale, which could far exceed 1,000 MW. In boiling water reactors, water serves as the coolant in the reactor core, as well as the heat-circulating fluid. The nuclear fuel used in a boiling water reactor is usually enriched uranium due to its relatively-high energy density that makes the continuous supply of large amounts of heat possible. Boiling Water Reactor (BWR) (as one of the Types of Nuclear Reactors)Ī boiling water reactor works through a closed continuous water-steam cycle, whereby water in the reactor vessel is heated to at least 287.8☌ or 550☏ by nuclear fission in the core, converted t o steam that is used to drive a turbine for electricity generation, and subsequently converted back to water by a circulating water-coolant. This article discusses the types of nuclear reactors, as follows ġ). Types of nuclear reactors are Boiling Water Reactor (BWR), Pressurized Water Reactor (PWR), Light Water Graphite-Moderated Reactor (LWGR), Advanced Gas-Cooled Reactor (AGR), Fast Neutron Reactor (FNR), Small Nuclear Reactor (SMR), Molten Salt Reactor (MSR). ![]()
