M1DX is a multipurpose, one-dimensional (plane, cylinder, sphere) diffusion theory code for use in fast reactor analysis. M1DX is a Merger of the HEDL H1DX and the LANL SUPERX codes, which are both based on 1DX. The code is designed to: compute k/sub eff/ and perform crticality searches on time absorption (..cap alpha..), reactor dimensions, and buckling by means of either a flux or an adjoint model; compute and output collapsed microscopic and macroscopic cross sections averaged over the spectrum in any specified zone; and compute and output resonance shielded cross sections using data in the Russian format.
