The Power Shape Monitoring System (PSMS) is a computer system for monitoring and prediction of BWR reactor cores. It can be used by the site nuclear engineers as well as the core follow engineers of the downtown office. The PSMS was installed at Oyster Creek in 1978 for testing and it is now used as their core monitoring system. In addition, the PSMS is also the starting point for a recently initiated effort of standardizing reactor core monitoring systems. The PSMS uses a 3D nodal code (NODE-B/THERM-B) to estimate the core power distribution. It has been demonstrated that adaptation of this code to partially fit the TIP and LPRM readings followed by a statistical characterization of the remaining errors results in better accuracy and improved sensitivity for anomaly detection compared to an approach that is entirely dependent upon the detector readings.
