PWR primary flow measurements by correlation analysis of nitrogen 16 fluctuations

Transit time flow measurements by means of correlation methods have been applied in many cases and the state-of-the-art is well defined at the present time. However, the application of such a method for accurate PWR primary flow control in industrial conditions, entails the solving of important problems, concerning measurements errors and experimental outfit design. This paper presents theoretical developments and results of experimental investigations that have been carried out on french PWRs.
