VARI3D (Perturbation Theory Codes)

Standard Code Description

VARI3D is a generalized perturbation theory code that allows calculation of the effects on reactivity and reaction rate ratios of alterations in microscopic cross sections and/or material number densities. VARI3D is most frequently used to compute the reactivity coefficient distributions and kinetics parameters employed in reactor dynamics and safety analyses. The flux and adjoint distributions required to compute these quantities are provided by DIF3D.
