Method for obtaining load-following capability in natural circulation, free-surface separation boiling water reactors
This patent describes an improvement in a natural-circulation boiling water reactor (BWR). It is of the free-surface separation type wherein housed within a reactor pressure vessel (RPV) is a nuclear core which with the RPV defines an annulus region which is in flow communication with a core lower plenum region disposed beneath the nuclear core, a first upper steam dryer assembly connected to a steam outlet in the RPV, a chimney mounted atop the core and in fluid communication with the first upper steam dryer assembly, the region outside of the chimney defining a down-comer region which also is in fluid communication with the chimney, free-surface steam separation occurring within the chimney, and a feedwater inlet disposed in the RPV. The improvement is for obtaining load-following capability.
