Description
Strong oscillations in fluid velocities and densities have been measured in the LOBI PWR simulator during natural circulation tests. A sort of 'syphon condensation' occurs in the loop when the primary side mass inventory roughly equals 70% of the initial value. RELAP5/MOD2 code predicts oscillations of the same quantities with similar frequency. This report deals with the analysis of the above physical phenomena even from the code calculation point of view.
