Exnihilo is a modern radiation transport framework that implements a variety of advanced solvers and solution method- ologies, enabling it to solve a wide variety of nuclear engineering and applications problems with the scalability to run on both desktop machines and leadership-class supercomputers. It supports "stand-alone" execution using its internal front ends, but its components (such as the the Denovo S_N solver) are also integrated into other radiation transport codes.
