WebBWR design. It assumes a rupture of one of the pipes connecting the external circulating pump with the reactor vessel. The BWR LOCA involves a more gradual depressurization than the PWR. The reason is that the main coolant pipe diameter in the BWR is 50 cm in diameter compared with 80 cm in the PWR.

A boiling water reactor (BWR) is a type of light water nuclear reactor used for the generation of electrical power. It is a design different from a Soviet graphite-moderated RBMK. It is the second most common type of electricity-generating nuclear reactor after the pressurized water reactor (PWR), which is … Ver mais A boiling water reactor uses demineralized water as a coolant and neutron moderator. Heat is produced by nuclear fission in the reactor core, and this causes the cooling water to boil, producing steam.
