Power Plant Diagram Boiling Water Reactor - Various types of reactors are being used in practice for power plant purposes, viz., advanced gas reactor (AGR), boiling water reactor (BWR), and heavy water moderated reactor, etc. CANDU reactor Natural uranium (in oxide form), pressurized heavy water moderated is adopted in India.. English: Nuclear reactor: boiling water type. Water is heated through the controlled splitting of uranium atoms in the reactor core and turns to steam. Pumps force the water through the reactor at top speed, maximizing steam production. Steam drives the turbines that turn the generator that makes electricity.. A boiling water reactor (BWR) is cooled and moderated by water. It takes place at a lower pressure as in PWR, what allows the water to boil inside the pressure vessel producing the.

The temperature-entropy diagram (Ts diagram) in which the thermodynamic state is specified by a point on a graph with specific entropy (s) as the horizontal axis and absolute temperature (T) as the vertical axis, is the best diagram to describe behaviour of a Carnot cycle.. Boiling water reactors (BWRs) are nuclear power reactors utilizing light water as the reactor coolant and moderator to generate electricity by directly boiling the light water in a reactor core to make steam that is delivered to a turbine generator.. in Fig. 4, water at about 2200 psia or 150 bars is pumped into a pressure vessel containing the reactor core shown. The water flows through an annular region between the reactor vessel and the reactor core and then its flow is distributed by a nozzle system to the core for cooling the fuel elements..

The water is allowed to boil in the reactor. The steam is generated as it heads out of the reactor and then flows through the steam turbine. One major disadvantage of a BWR is that, the coolant water comes in direct contact with fuel rods as well as the turbine.. The BWR reactor typically allows bulk boiling of the water in the reactor. The operating temperature of the reactor is approximately 570F producing steam at a pressure of about 1000 pounds per square inch. Current BWR reactors have electrical outputs of 570 to 1300 MWe. As this the PWR designs, the units are about 33% efficient.. BWR = boiling water reactor, PWR= pressurised water reactor, PHWR= pressurised heavy water reactor (CANDU). FBR= fast breeder reactor (at higher temperature). In Europe (especially Scandinavia) low water temperature is an important criterion for power plant location..

Figure 1.3b Schematic: Boiling Water Reactor (BWR) Water Cooled, Graphite Moderated the valves are 'fail safe' in that on loss of power they move to the safety position. • Operating lifetime of 60 years with a design plant availability of 90%+. Nuclear Reactor Types ). Nuclear Boiling Water Power Plant Closed System Water is heated through the controlled splitting of uranium atoms in the reactor core and turns to steam.. Schematic Diagram of Advanced Boiling Water Reactor (ABWR) Hitachi developed the ABWR in 1985, in collaboration with various international partners and support from power companies with experience in operating BWR plants..

Seen below is the flow of water through a boiling water reactor power plant, and its production of electricity. Figure 4. A boiling water nuclear reactor operates on a direct cycle, where the water from the core is also used as steam in the turbine section..
