Abstract : Any change in neutronic properties in a reactor operating at steady state will result in a change in the equilibrium neutron flux and hence, the power of the reactor. A main cause for a change in neutronic properties is the high temperature attained in a reactor, which produces a feedback in the reactor operation. The response of the reactor to a particular feedback is analyzed by using Liapunov's Second Method to specify stability regimes. Both, the pointkinetics model and the distributed parameters system are analyzed. Data from a typical thermal and fast reactors is used to specifically determine the stability domains. (Author)
