The effect of xenon and temperature on reactor dynamics in a free system is extended to include an explicit spatial dependence. The stability boundaries are determined in linear approximation for solid and annular cylindrical systems for several core sizes. Annular stability is found to be the hardest to achieve. It is shown that several terms in the series expansion of the fundamental are necessary to give a good representation of the stability of the first harmonic.
