Abstract

In this chapter, we describe a set of fuzzy systems which automate the manual part of procedures being used in the reactor operations for PWR-type nuclear power plants. One of the fuzzy systems evaluates the total power defect as a function of the boron concentration and the reactor power level. Others are used to compute the amount of step changes for the control rod as a function of the current rod position and the increment of the total power defect needed for the power level change. Each fuzzy system is either an exact or an approximate representation of the cubic spline interpolation for the corresponding function provided as graphs. The resulting set of fuzzy systems not only improves the efficiency in performing the curve readings but also reduces the interpolation errors involved.
