NONLINEAR EFFECTS IN XENON SPATIAL OSCILLATIONS

Technical Report ·
OSTI ID:4724618
Xenon feedback can produce spatial oscillations in large power reactors. Depending on the reactor size, materials inventory, power, and temperature coefficient, these oscillations may be either transient or persistent. This phenomenon is treated by a modal analysis in which nonlinear terms are retained. The nonlinear effects are shown to limit the amplitude of the oscillation and to cause the position of the flux peak to precess azimuthally; a formula for calculating the limiting amplitude of the oscillation is derived and compared with analog computer results.
