Extending nuclear power accident code for advanced reactor designs

A number of new nuclear reactor designs, such as small modular reactors and non-light water reactors, have been developed over the past 10 to 15 years. In order to help the Nuclear Regulatory Commission evaluate the safety of the next generation of reactors, fuel cycle facilities and fuel technologies, researchers at Sandia National Laboratories have been expanding their severe accident modeling computer code, called Melcor, to work with different reactor geometries, fuel types and coolant systems.

Simulating sneezes and coughs to show how COVID-19 spreads

Two groups of researchers at Sandia National Laboratories have published papers on the droplets of liquid sprayed by coughs or sneezes and how far they can travel under different conditions. Both teams used Sandia’s decades of experience with advanced computer simulations studying how liquids and gases move for its nuclear stockpile stewardship mission.
