what is the difference between pwr and bwr
Boiling water reactor The boiling water reactor (BWR) is a type of light water nuclear reactor used for the generation of electrical power. 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-1950s. The main present manufacturer is GE Hitachi Nuclear Energy, which specializes in the design and construction of this type of reactor.
Bachelor's degree A bachelor's degree (from Middle Latin baccalaureus) or baccalaureate (from Modern Latin baccalaureatus) is an undergraduate academic degree awarded by colleges and universities upon completion of a course of study lasting three to seven years (depending on institution and academic discipline). In some institutions and educational systems, some bachelor's degrees can only be taken as graduate or postgraduate degrees after a first degree has been completed. In countries with qualifications frameworks, bachelor's degrees are normally one of the major levels in the framework (sometimes two levels where non-honours and honours bachelor's degrees are considered separately), although some qualifications titled bachelor's degrees may be at other levels (e.g. MBBS) and some qualifications with non-bachelor's titles may be classified as bachelor's degrees (e.g. the Scottish MA and Canadian MD).
