Loss of Coolant Accident in a Natural Circulation Cooled Advanced BoilingWater Reactor

摘要

This research involved undergraduate students to perform safety analyses of an advanced lightwater reactor designs and to observe flow phenomena that occur during LOCA. Bothexperimental and computational methods were developed. The design and construction of asmall experimental facility capable of modeling specific aspects of phenomena during LOCA andthe development of a thermal-hydraulics model for the facility were implemented. This facilitywas completed by first performing detailed scaling methods, which allowed for design anddevelopment of a physical experimental facility to produce and gather data, followed bymodeling with RELAP5 thermalhydraulics codes to compare physical data to computationallygenerated data.
