Abstrakt:	Тhe paper considers the dynamics of a power pulse in a periodically pulsed reactor with allowance for fast reactivity feedback. The calculation method includes a system of coupled equations based on one-point kinetics of the reactor and on two models of thermoelastic behavior of reactor fuel rods: approximation of a reactor core as a one-dimensional oscillator, and a more realistic approach considering the propagation of elastic waves through a single rod. It is shown that the oscillator model with reasonably chosen parameters yields results close to those of the wave model. [ABSTRACT FROM AUTHOR]
