Web• A BWR produces steam directly by boiling the water coolant. The steam is separated from the remaining and passed to the turbines, then condensed and recycled. • In GCRs (gas-cooled reactors) and AGRs (advanced gas-cooled reactors) carbon dioxide is used as the coolant and graphite as the moderator. Like heavy WebBoiling water reactors (BWR) are a type of nuclear reactor that use light water (ordinary water, as opposed to heavy water) as their coolant and neutron moderator.They are the second most used reactor for nuclear … WebThe PWR also uses light water as both coolant and moderator. However, in the pressurized water system the cooling water is kept under pressure so that it cannot boil. As a consequence the PWR differs in another respect from the BWR; the primary coolant that flows through the reactor core does not drive the steam turbine. most read genre of books
