Software Analysis Tool
Pass 2 Calibration Analysis is the determination of calibration status for each Wear Rate Analysis (WRA) run in the CHECWORKS™ SFA model. It involves using inspection data to adjust the CHECWORKS™ SFA algorithm predictions to better correlate with actual plant wear conditions. It also helps the user determine a degree of confidence in the model predictions.
Without a Pass 2 Analysis, all WRA runs in the CHECWORKS™ SFA are considered non-calibrated. This means Pass 2 Analysis results do not reflect actual plant conditions.
Relative FAC wear rates can be used, but the predicted remaining service life is not an indicator of the actual remaining life. Therefore, more inspections are required to understand wear trends in a WRA run, leading to additional inspections in low- wear areas of the plant.
GSE Engineering, Programs & Performance (formerly True North Consulting) has provided the nuclear industry with Flow Accelerated Corrosion (FAC) program support for the past twenty years. Our team of FAC program subject matter experts (SMEs) works with most of the US utilities in support of their FAC programs including performing a significant number of Pass 2 Calibrations each year.
GSE has developed an innovative Pass 2 Calibration tool built on our quality TSM Enterprise Software platform already in use at many utilities in the industry to support this and provide an additional benefit to the FAC industry. The Pass 2 Calibration tool will automate the overall process. thereby reducing the level of manual effort and reducing/eliminating potential human errors.
