Introduction of the Quasi-Static Synthesis Method for Solution of Space-Time Reactor Kinetics Problems

An improved space-time kinetics method that can be applied to the analysis of either fast or thermal reactor transients is presented. The method blends the concepts of formal reduction (i.e., the quasi-static method) and time synthesis into a single unified approach (called quasi-static synthesis) to handle spacetime equations. Preliminary results obtained with the method indicate reduced computer time, while maintaining computational accuracy, when compared to several other kinetics methods presently in use.
