Uncertainty and sensitivity analyses of the Kozloduy pump trip test by coupled RELAP5/PARCS code

Bousbia Salah, A.; Kliem, S.; Rohde, U.
The modeling of complex transients in Nuclear Power Plants (NPP) remains a challenging topic for Best Estimate three-dimensional coupled code computational tools. This technique is, nowadays, extensively used since it allows decreasing conservatism in the calculation models and performs more realistic simulating and more precise consideration of multidimensional effects under complex transients in NPPs. In the current paper a contribution to the assessment and validation of coupled code technique through the Kolzoduy VVER100 pump trip test is performed. For this purpose, the coupled REALP5/3.3-PARCS/2.6 code is used. The code results were assessed against experimental data and the comparison study shows good agreements between the calculations and the global kinetic and thermal-hydraulic aspects observed experimentally. Further investigations through the uncertainty and sensitivity GRS method, covering kinetic and thermal-hydraulic parameters, have been carried out in order to assess the origin of the observed discrepancies.
