DESCRIPTION:The Random Ray Method is a recently developed multigroup metho
 d for performing 3D neutron transport. The new method uses randomly sample
 d rays that are ray-traced through a geometry to iteratively solve for the
  flux distribution and eigenvalue -- a process which shares some common ro
 ots with the deterministic Method of Characteristics. Beyond being very si
 mple and easy to implement\, the method’s stochastic nature provides sur
 prising advantages compared to existing transport methods. The Advanced Ra
 ndom Ray Code (ARRC) implements the random ray method and can converge ful
 l core 3D light-water reactor problems in high-fidelity on both CPU- and G
 PU-based supercomputers. Random ray has also recently been implemented in 
 the OpenMC and SCONE Monte Carlo codes. In this seminar\, I will explain h
 ow (and why) random ray transport works\, demonstrate the method on a vari
 ety of problems\, compare its performance against other transport methods\
 , and present a brief roadmap for future research topics in the field. \n\
