Argonne assists advanced reactor development with award-winning safety software
The development of modern nuclear reactor technologies relies heavily on complex software codes and computer simulations to support the design, construction, and testing of physical hardware systems. These tools allow for rigorous testing of theory and thorough verification of design under various use or transient power scenarios.

Gas puff imaging is a two-dimensional diagnostic that measures the edge D light emission from a neutral D2 gas puff near the outer midplane of the National Spherical Torus Experiment (NSTX). DEGAS 2 is a three-dimensional Monte Carlo code used to model neutral transport and plasma-neutral interactions in fusion plasmas. In this paper, we compare the measured and modeled D light emission for specific NSTX experiments. Both the simulated spatial distribution and the radiance of the D light emission agree well with the experimental data obtained during time periods between edge-localized modes (ELMs) in ELMy H-modes.
