CFD and System Code Validation for HTGR Applications Leveraging HTTF Data

Accurate modelling and simulation tools for thermal hydraulic calculations are a key element needed to efficiently develop and deploy new advanced reactors including HTGRs. Uncertainties in modelling and simulation can have significant safety and economic implications. Well defined benchmark problems are an efficient means to quantify accuracy and identify sources of uncertainties in thermal hydraulic calculations. This panel discusses how data measured at HTTF can be leveraged and is used in the OECD HTTF TH benchmark. Experts from industry, DOE and academia will discuss the value of measured data and associated benchmarks to validate simulation codes.
