2DB is a two-dimensional (X-Y, R-Z, R-0), multigroup diffusion code for use in fast reactor criticality and burnup analysis. The code can be used to: Compute k_eff and perform criticality searches on buckling, time absorption (α), reactor composition, and reactor dimensions by means of either a flux or an adjoint model; Compute material burnup. All programming is in FORTRAN-IV. Since variable dimensioning is employed, no simple restrictions on problem complexity can be stated. However, in a 65K memory, the current version is nominally restricted to 50 energy groups. Running time (for a k_eff calculation) on a UNIVAC 1108 is about 1 minute for a 30 x 30 mesh problem using 4 energy groups.
