The boiling water reactor BWR is a type of light waternuclear reactor used for the generation of electrical power. Steam Offline Activation: Software' title='Steam Offline Activation: Software' />It is the second most common type of electricity generating nuclear reactor after the pressurized water reactor PWR, also a type of light water nuclear reactor. The main difference between a BWR and PWR is that in a BWR, the reactor core heats water, which turns to steam and then drives a steam turbine. In a PWR, the reactor core heats water, which does not boil. This hot water then exchanges heat with a lower pressure water system, which turns to steam and drives the turbine. The BWR was developed by the Idaho National Laboratory and General Electric GE in the mid 1. The main present manufacturer is GE Hitachi Nuclear Energy, which specializes in the design and construction of this type of reactor. OvervieweditThe boiling water reactor BWR uses demineralized water as a coolant and neutron moderator. Heat is produced by nuclear fission in the reactor core, and this causes the cooling water to boil, producing steam. The steam is directly used to drive a turbine, after which it is cooled in a condenser and converted back to liquid water. This water is then returned to the reactor core, completing the loop. The cooling water is maintained at about 7. MPa, 1. 00. 01. 10. C 5. 50 F. In comparison, there is no significant boiling allowed in a pressurized water reactor PWR because of the high pressure maintained in its primary loopapproximately 1. MPa, 2. 30. 0 psi. The core damage frequency of the reactor was estimated to be between 1. ComponentseditCondensate and feedwatereditSteam exiting the turbine flows into condensers located underneath the low pressure turbines, where the steam is cooled and returned to the liquid state condensate. The condensate is then pumped through feedwater heaters that raise its temperature using extraction steam from various turbine stages. Feedwater from the feedwater heaters enters the reactor pressure vessel RPV through nozzles high on the vessel, well above the top of the nuclear fuel assemblies these nuclear fuel assemblies constitute the core but below the water level. The feedwater enters into the downcomer or annulus region and combines with water exiting the moisture separators. The feedwater subcools the saturated water from the moisture separators. This water now flows down the downcomer or annulus region, which is separated from the core by a tall shroud. The water then goes through either jet pumps or internal recirculation pumps that provide additional pumping power hydraulic head. The water now makes a 1. Water exiting the fuel channels at the top guide is saturated with a steam quality of about 1. Typical core flow may be 4. However, core average void fraction is a significantly higher fraction 4. These sort of values may be found in each plants publicly available Technical Specifications, Final Safety Analysis Report, or Core Operating Limits Report. The heating from the core creates a thermal head that assists the recirculation pumps in recirculating the water inside of the RPV. A BWR can be designed with no recirculation pumps and rely entirely on the thermal head to recirculate the water inside of the RPV. The forced recirculation head from the recirculation pumps is very useful in controlling power, however, and allows achieving higher power levels that would not otherwise be possible. The thermal power level is easily varied by simply increasing or decreasing the forced recirculation flow through the recirculation pumps. The two phase fluid water and steam above the core enters the riser area, which is the upper region contained inside of the shroud. 08 Kristall Rush on this page. The height of this region may be increased to increase the thermal natural recirculation pumping head. At the top of the riser area is the moisture separator. By swirling the two phase flow in cyclone separators, the steam is separated and rises upwards towards the steam dryer while the water remains behind and flows horizontally out into the downcomer or annulus region. In the downcomer or annulus region, it combines with the feedwater flow and the cycle repeats. The saturated steam that rises above the separator is dried by a chevron dryer structure. The wet steam goes through a tortuous path where the water droplets are slowed down and directed out into the downcomer or annulus region. The dry steam then exits the RPV through four main steam lines and goes to the turbine. Control systemseditReactor power is controlled via two methods by inserting or withdrawing control blades and by changing the water flow through the reactor core. Positioning withdrawing or inserting control rods is the normal method for controlling power when starting up a BWR. As control rods are withdrawn, neutron absorption decreases in the control material and increases in the fuel, so reactor power increases. As control rods are inserted, neutron absorption increases in the control material and decreases in the fuel, so reactor power decreases. Differently from the PWR, in a BWR the control rods boron carbide plates are inserted from below to give a more homogeneous distribution of the power in the upper side the density of the water is lower due to vapour formation, making the neutron moderation less efficient and the fission probability lower. In normal operation, the control rods are only used to keep a homogeneous power distribution in the reactor and compensate the consumption of the fuel, while the power is controlled through the water flow see below. Some early BWRs and the proposed ESBWR Economic Simplified BWR made by General Electric Hitachi designs use only natural circulation with control rod positioning to control power from zero to 1. Changing increasing or decreasing the flow of water through the core is the normal and convenient method for controlling power from approximately 3. When operating on the so called 1. As flow of water through the core is increased, steam bubbles voids are more quickly removed from the core, the amount of liquid water in the core increases, neutron moderation increases, more neutrons are slowed down to be absorbed by the fuel, and reactor power increases. As flow of water through the core is decreased, steam voids remain longer in the core, the amount of liquid water in the core decreases, neutron moderation decreases, fewer neutrons are slowed down to be absorbed by the fuel, and reactor power decreases. Reactor pressure in a BWR is controlled by the main turbine or main steam bypass valves. Unlike a PWR, where the turbine steam demand is set manually by the operators, in a BWR, the turbine valves will modulate to maintain reactor pressure at a setpoint. Under this control mode, the turbine will automatically follow reactor power changes. When the turbine is offline or trips, the main steam bypassdump valves will open to direct steam directly to the condenser.
