| Popis: |
For safety reasons, reactor coolant system (RCS) flows in nuclear power plants have to be maintained between a high and a low limit. The current measurement uncertainty is impacted by the heterogeneity of the RCS fluid. The objective of the present study is to use the existing plant elbow taps to measure accurately and absolutely the RCS flow continuously and independently of the temperature measurement. CFD simulations are used to find out a calibration coefficient for the method. An uncertainty calculation is performed. This innovative method was tested on actual data issued from French nuclear power plants. |
