A perturbation code for conventional assembly homogenized diffusion problems
VARI3D is a code based upon DIF3D-FD that is used to generate kinetics parameters and perturbation theory based reactivity coefficients for use in a conventional point kinetics based safety analysis of a reactor. VARI3D can also generate R-Z based sensitivity coefficients for use in an uncertainty assessment.
VARI3D is distributed with PERSENT.
