The pressurized water reactor is a type of nuclear reactor.This type of reactor's main characteristic is that the water uses high pressure in the primary circuit to prevent it from boiling. Pressurized Water Reactor Simulated by TRACE, Advanced nuclear reactor in nuclear power station, Nuclear waste disposal-geological importance, Preferred Utilities Manufacturing Corporation, No public clipboards found for this slide, Power Plant Engineering: Pressurised Water Reactor. This is contained within the drywell within a steel containment which is itself contained within the outer, reinforced concrete shield building. Boiling Water Reactors (BWR) Unlike the PWR, inside the boiling water reactor, the primary water system absorbs enough heat from the fission process to boil its water. The steam … Pressurized water reactor uses nuclear power in the form of enriched Uranium. This heats the light water used for producing steam. In the boiling water reactor the same water loop serves as moderator, coolant for the core, and steam source for the turbine.. Built in 1963 by Allis-Chalmers, the control rod drives entered from the bottom rather than through the top head as per standard configuration. In such a reactor, water is used as a coolant. In contrast to the PWR, the BWR uses only two separate water systems as it has no separate steam generator system. See our Privacy Policy and User Agreement for details. The main steam system transports steam from the reactor vessel to the turbines that power the plant's electrical generator. Light-water reactors (LWRs) are power reactors that are cooled and moderated with ordinary water.There are two basic types: the pressurized-water reactor (PWR) and the boiling-water reactor (BWR). 0000004040 00000 n 0000004845 00000 n 0000004319 00000 n 0000005519 00000 n This hot water then exchanges heat with a lower pressure water system, which turns to steam and drives the turbine.
