In large-scale systems like nuclear systems, automation frees operators from vigilance over routine and tedious tasks by emulating the human expertise in a faster and reliable fashion. The nuclear power plant operational data indicate that the conventional control system may fail when plant nonlinearities and their parameter changes become significant. Typical examples in pressurized water reactors (PWRs) are the power oscillations due to nonlinear xenon behavior, and large level swings of steam generators due to the swell and shrink effects during startup. Since the conventional automation technologies are not completely suitable, their operations are primarily dependent on plant operators. Since the power distribution and steam generator level controls have been the most challenging control problems in the nuclear field, there have been a number of research activities in these areas. Among many controllers proposed to replace the manual operations, the neuro-fuzzy control method is generally regarded as a suitable control method due to its human-like characteristics.
