Abstract

This report assesses the predictive capabilities of the Transient Reactor Analysis Code (TRAC-PD2) using data from the SUPER CANON and HEISS DAMPF REACTOR (HDR) experimental facilities. The report is divided into three parts. Part I is the TRAC-PD2 assessment using SUPER CANON data. Part II is the TRAC-PD2 assessment using HDR data. Part III provides recommendations for the user using the combined assessment results. In general, it is shown that the TRAC-PD2 predictions were in good agreement with the actual test pressures and and mass flow rates for both these tests. TRAC-PD2 provided considerably better results than TRAC-P1A. This was particularly true with regard to sound velocity predictions which play a significant role whenever the speed of pressure relief waves must be determined.
