The theory of the core-collapse supernova (CCSN) explosion mechanism relies on an accurate treatment of neutrino transport inside the exploding star. There is a wealth of physical processes that become important at different times and locations, large neutrino optical depths, and nontrivial geometries that make understanding neutrino-driven explosions particularly interesting and challenging. Many state of the art simulations of CCSNe employ a moment-based transport scheme that employs an approximate closure relation. I will describe a method to provide a closure via a time-independent Monte Carlo transport calculation at every timestep and will present test one-dimensional simulations of CCSNe using this method. Finally, I will comment on the state of the field of neutrino flavor transformations in CCSNe and the numerical challenges simulating these effects presents.
