Modeling of the PACTEL Facility and Simulation of a Small Break LOCA Experiment With the TRACE V5.0 Code

Abstract

The applicability of the TRACE code to analyze VVER type PWRs is being studied in Finland. To this end the PACTEL integral test facility of Lappeenranta University of Technology (LUT), has been modeled using the TRACE V5.0 patch2 code. PACTEL is a full height model of VVER-440 type nuclear reactor located in Loviisa. A small break loss-of-coolant-accident (SBLOCA) experiment SBL-30 with multiple loops included in the test was chosen to be simulated using the model. The calculation results succeeded reasonably well in estimating the experiment propagation.
