ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

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.
