APPROACH

1. BTB Jansky generates a plant model and maps the plant process conditions before and after retrofit.
2. ProcessPLUS^™ Acceptance Test is performed remotely at the location of the BTB Jansky offices. Process data is analyzed off-site.
3. Process modeling is usually done 3-4 weeks prior to retrofit. After receiving the pre-retrofit process data the reconciliation of data is performed and results are presented.
4. The final results of the delta analysis in the course of a ProcessPLUS^™ Acceptance Test are available after receiving the post-retrofit process data. One week later, the official acceptance test report is handed over.

During the performance of a ProcessPLUS^™ Acceptance Test, two datasets from two different time intervals (pre- and post retrofit) are evaluated using the same reconciliation model.

The analysis can be performed using operational data only. Additional measurements are not needed which saves considerable costs. During the ProcessPLUS^™ Acceptance Test, BTB Jansky is adhering to the methodology of the

Delta (Δ) Analysis:

Possible systematic errors in both analyzed time intervals of the delta analysis are therefore eliminated.

ADVANTAGES

1. Data reconciliation with ProcessPLUS^™ minimizes the uncertainties of process values and therefore yields the most precise process values possible in the mathematical-statistical sense.
2. ProcessPLUS^™ Acceptance Test yields results with a higher precision than customary industry acceptance tests.
3. ProcessPLUS^™ Acceptance Test has been performed for numerous retrofits at various nuclear power plant sites.
4. ProcessPLUS^™Acceptance Test is accepted by utilities and component suppliers.
