This report has been prepared as a part of the Agreement on Research Participation and Technical Exchange under the Code Assessment and Maintenance Program.
The data collected by Kalinin NPP Unit-1 Data Acquisition System and In-Vessel Monitoring System during stop of feedwater supply to the SG-4 transient have been analyzed by using the RELAP5/MOD3.2 and RELAP5/MOD3.2.2Beta codes. Kalinin NPP-1 is a Russian designed four loop pressurized water reactor (VVER-1000, project V-338) rated at 1000 MWe.
RELAP5 code calculated results were compared with plant data. Sensitivity studies were carried out to investigate the effects of modeling on major thermal-hydraulic parameters and to examine a new heat transfer model for horizontal tube bundles.
