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. 0000005120 00000 n
Clipping is a handy way to collect important slides you want to go back to later. PWR is the most common type of nuclear reactor, representing about 60% of all nuclear power reactors in the world. The abbreviation for Boiling Water Reactor is BWR. While similar to a BWR nuclear a PWR has a different way of producing steam in the form of a heat exchanger As an effect of this, only localized boiling occurs and steam will recondense promptly in the bulk fluid. 0000002750 00000 n
A BWR nuclear power plant consists of the reactor coolant recirculation system and main steam system that compose a nuclear reactor, engineered safety features that consist of the emergency core cooling system, reactor core isolation cooling system, containment cooling system and boric-acid injection system, turbine and generator equipment and other systems, such as the reactor … GEH has a full range of new nuclear plant services available and can tailor solutions to help customers overcome new plant challenges and experience better project development and execution.
