Nodalization of Advanced Heavy Water Reactor Core for Efficient Spatial Control

摘要

Large nuclear reactors, like the Advanced Heavy Water Reactor, are susceptible to instabilities in spatial power distribution due to their loose neutron coupling. This puts forth a challenging requirement of spatial power control, in addition to the total power control requirements, in such reactors. This is generally accomplished through a tactful distribution of neutron detectors and reactivity control devices within the reactor core. However, optimization of the number and positions of such monitoring and control devices demands an extensive analysis of the reactor core based on control theoretic approach.
