Advanced Power Plant Modeling with Applications to an Advanced Boiling Water Reactor and a Heat Exchanger

Advanced methods that use continuity wave equations in fluid flow paths and exact solutions of these and all other differential equations are applied to transient performance models of a counter flow heat exchanger and an Advanced Boiling Water Reactor (ABWR). The continuity wave equations for single and two-phase flow, with heat addition, are developed, and the exact solution for a typical lead lag circuit is presented. The models using these equations are described, and transient performance results are presented. These results are more accurate and are obtained with larger time intervals because of the exact solutions used. It is concluded that these two advanced methods have been successfully applied to the selected models.
