A Control System For A Power Plant Research Paper

A Control System For A Power Plant - Research Paper Example In some pressurized water reactors, distinctive control rods are used to facilitate the core to withstand a low level of power proficiently (Levine, 1999). Coolant. A liquid flowing inside the core so as to transmit the heat from it.   In light water reactors, the water mediator functions also as a major coolant. Except in boiling water reactors, there is subordinate coolant circuit where the water is changed into steam. Pressure vessel or pressure tubes. Normally, a strong steel vessel enclosing the reactor core and the coolant, but a series of tubes holding the fuel and transmitting the coolant through the adjacent moderator may be used. This has helped in the yielding of electricity that enhances other types that are costly and seasonal (Lee, 2004). Steam generator. Part of the cooling compartment where the high-pressure basic coolant taking heat from the reactor is incorporated to make steam for the turbine, in an adjacent circuit. Basically, a heat exchanger like a motor vehicle radiator. Reactors may have up to four coils, each with a steam generator.   Containment. The organization around the reactor and related steam generators which is intended to protect it from outside interruption and to protect those outside from the impacts of radiation in case of any crucial fault inside. It is usually a meter thick steel and concrete structure. Powering a nuclear plant reactor: Most reactors need to be turned off for refueling, so that the pressure tubes can be opened up. In this case, topping up is at intervals of 1-2 years, when a 1/4 to a 1/3 of the fuel assemblies are changed with fresh ones. In case graphite or water is used as a coolant, it is possible to drive a power reactor on natural instead of impure uranium. Natural uranium has the similar elemental build-up as when it was mined, while impure uranium has
