A Methodology for Global Sensitivity Analysis for Time-Dependent Code Output Applied to Reflood Simulation in TRACE

Damar Canggih Wicaksono, Andreas Pautz, Omar Zerkak

Understanding properly the impact of model parameters and their interactions on the predictions is required for an appropriate model assessment. For simulation of reflooding following a LOCA, this requirement is justified because the important parameters a ...

Exploring Variability in Reflood Simulation Results: an Application of Functional Data Analysis

Damar Canggih Wicaksono, Andreas Pautz, Omar Zerkak

In this paper we followed the functional data analysis (FDA) paradigm to summarize the output of computer code simulating a reflood transient. The paradigm stands on the assumption that the data (code output) is generated by a smooth, albeit complex, proce ...

Sensitivity Analysis of a Bottom Reflood Simulation using Morris Screening Method

Damar Canggih Wicaksono, Andreas Pautz, Omar Zerkak

In the work presented in this paper, a sensitivity analysis using the Morris screening method was carried out for a model of the Flooding Experiment with Blocked Arrays (FEBA) separate-effect test facility. The sensitivity analysis was conducted in the con ...

Application of Power Time-Projection on the Operator Splitting Coupling Scheme of the TRACE/S3K Coupled Code

Rakesh Chawla, Damar Canggih Wicaksono, Hakim Ferroukhi, Omar Zerkak

This paper reports refinement studies on the temporal coupling scheme and time-stepping management of TRACE/S3K, a dynamically coupled code version of the thermal-hydraulics system code TRACE and the 3D core simulator Simulate-3K. The studies were carried ...

Cross-section modelling effects on pressurised water reactor main steam line break analyses

Rakesh Chawla, Hakim Ferroukhi, Omar Zerkak

Because of the strong asymmetric overcooling effects occurring during a PWR main steam line break (MSLB) event, an accurate analysis of this transient requires the use of 3-D kinetics methods. An assessment has been made of the relative performance of the ...
