SCEPTRE 2.2 Angular Quadrature Sets

Drumm, Clifton R.; Pautz, Shawn D.; Bruss, Donald E.; Fan, Wesley C.

This document includes details of the angular quadrature sets available in SCEPTRE for performing numerical integrations in the angular phase space. The angular dependence of the boundary and fixed-source terms an d initial angular flux are specified by angular index rather than by direction. It is, therefore, necessary to know the mapping from a specific direction to a direction index. This document includes angular quadrature weights and direction cosines for most of the quadrature sets available in SCEPTRE.
