Nuclear application software package

Abstract

The Nuclear Application Software Package generates a full-core distribution and power peaking analysis every six minutes during reactor operation. Information for these calculations is provided by a set of fixed incore, self-powered rhodium detectors whose signals are monitored and averaged to obtain input for the software. Following the calculation of a power distribution and its normalization to a core heat balance, the maximum power peaks in the core and minimum DNBR are calculated. Additional routines are provided to calculate the core reactivity, future xenon concentrations, critical rod positions, and assembly isotopic concentrations.
