CONTROL OF XENON SPATIAL OSCILLATIONS

Technical Report ·
OSTI ID:4702947
An automatic delayed-reactivity feedback based on exit coolant temperature is shown to lead to an increase in linear stability against xenon oscillations when the delay time is within a few percent of the free period of oscillation. Numerical calculations showed that the stabilizing effect extends into the nonlinear range as well. It is shown that dead-band control is spatially destabilizing if the dead band width is too small. A width of plus or minus 5% was, however, found to be sufficient to avoid this form of instability for large changes in power demand. (auth)
