Utility experience with the BWR power shape monitoring system

The Oyster Creek Nuclear Generating Station has used the Electric Power Research Institute (EPRI) boiling water reactor (BWR) power shape monitoring system (PSMS) for approximately one cycle of power operation. During this time, the PSMS was used for both on-line core monitoring and off-line core simulation. The ability to obtain core power distributions in near real time and the ability to simulate anticipated core maneuvers has enabled site personnel to avoid difficult operational situations and to more easily detect problems when they occur. The PSMS is an integrated set of computer codes used to monitor and predict the nuclear and thermal-hydraulic behavior of a BWR code. The PSMS uses a three-dimensional, one-energy-group nodal model similar to the General Electric FLARE code to estimate the core power distribution. The PSMS contains four major modules: (1) data acquisition and storage module: collects plant data; (2) duty cycle approximation module; performs three-dimensional nuclear and thermal-hydraulic calculations; (3) model calibration module: performs all statistical evaluations; and (4) data display module: responsible for displaying PSMS data. The PSMS also has the ability to perform useful predictive calculations. These include: power, flow, or control rod searches; control rod pattern optimizations; and fast approximate predictions.
