摘要: Abstract The paper presents the mathematical modeling of space–time kinetics phenomena in Advanced Heavy Water Reactor (AHWR), a 920 MW (thermal), vertical pressure tube type thorium based nuclear reactor. physical dimensions and internal feedback effects AHWR are such that it is susceptible to xenon induced spatial oscillations. For study design suitable control strategy, need for model which not very large order arises. In this paper, reactor within framework nodal derived with two group neutron diffusion equation as basis. A linear standard state space form formulated from set equations so obtained. It has been shown comparison system properties could be helpful deciding upon an appropriate nodalization scheme thus obtaining reasonably accurate model. validation, transient response simplified compared those rigorous finite-difference
