Stability analysis can be performed by transient analysis using different system codes which model the phenomena in detail. These system codes can capture the intrinsic nonlinearities in the system but the simulations have to be performed for different values of parameters and initial perturbations. This becomes a computationally intensive work and the estimation of the stability characteristics for the entire domain is difficult using this method. In this study, the effect of Core length (L)/Core diameter (D) ratio on stability characteristics of different modes of spatial Xenon oscillations in a large Pressurized Heavy Water Reactor has been analyzed using multipoint kinetics coupled with Xenon and Iodine equations.
