Abstract
This work proposes the use of genetic programming (GP)
for automatic design of a fuzzy expert system aimed to
provide the control of axial xenon oscillations in
pressurized water reactors (PWRs). The control
methodology is based on three axial offsets of xenon
(AOx), iodine (AOi) and neutron flux (AOf), effectively
used in former work. Simulations were made using a
two-point xenon oscillation model, which employs the
non-linear xenon and iodine balance equations and the
one group, one-dimensional neutron diffusion equation,
with non-linear power reactivity feedback, also
proposed in the literature. Results have demonstrated
the ability of the GP in finding a good fuzzy strategy,
which can effectively control the axial xenon
oscillations.
