PMCR - A Power Mapping and Calibration Routine for 600 MWe CANDU-PHW Reactors

Abstract

In 600 MWe CANDU-PHW reactors PMCR (Power Mapping and Calibration Routine) will be used on-site for calibration of the regional overpower system. PMCR will be executed off-line in one of the station computers. The program calculates accurate channel power maps by incorporating a fuel burnup dependent flux to power conversion algorithm. Fuel burnup is calculated by PMCR, hence it is independent of other software. Extensive comparisons with the uniform flux/power conversion approximations were made. Significant improvements in power mapping accuracy are achieved with PMCR.
