Boiling Water Reactor (BWR) Systems

Inside the boiling water reactor (BWR) vessel, a steam water mixture is produced when very pure water (reactor coolant) moves upward through the core abso rbing heat. The major difference in the operation of a BWR from other nuclear systems is the steam voi d formation in the core. The steam-water mixture

to change, the steam exits the steam generator, and th e water is drained back for reuse. The two stage process of moisture removal is so efficient at re moving the water that for every 100 pounds of steam that exits the steam generator, the water content is less than 0.25 pounds. It is important to maintain the
