Advanced simulation in support to GIF reactor design studies – Contribution of High-Performance Computing (HPC) and Uncertainty Quantification (UQ)

The Generation IV International Forum (GIF) Advanced Simulation Workshop, held on October 27, 2013, in Monte Carlo, focused on the latest advancements in high-performance computing (HPC) and simulation techniques for nuclear engineering. Experts discussed uncertainty analysis in safety studies, CFD applications, multi-physics modeling, and next-generation safety analysis codes. The workshop highlighted the role supercomputing could play in supporting the design and operation of Generation IV reactor systems.

The day featured key presentations, including:

• “Best Estimate Plus Uncertainty” safety studies at the conceptual design phase of the ASTRID demonstrator, M. MARQUÈS, France
• "Experience of adaptation and application of 3D thermal-hydraulic calculation for definition of non-isothermal flows in reactor plant structural components", A. V. BUDNIKOV, Russian Federation
• "Prospects of next generation safety analysis code and experiences of high-performance computing", B. D. CHUNG, Korea
• "Supercomputing as a base for extending usage of turbulence resolving approaches in nuclear thermal-hydraulic analysis", D. ZAYTSEV, Russian Federation
• "Use of intensive simulation supporting SFR uncertainty driven core design process: presentation of multi-physics TRIAD package", E. HOURCADE, France
• "High Performance Computing for CFD problems and uncertainties quantification", V. STRIZHOV, Russian Federation
• "Experiences of LBLOCA uncertainty quantification and 3-D whole-core transport based nuclear analysis system", DeCART/ CHORUS/ MASTER, C. J. PARK, Korea
