2DB is a two-dimensional (X-Y, R-Z, R-e), multigroup diffusion code for use in fast reactor criticality and burnup analysis. All programming is in FORTRAN-IV. The code can be used to: 1) Compute k_eff and perform criticality searches on time absorption (α), reactor composition, and reactor dimensions by means of either a flux or an adjoint model; (2) Compute material depletion rates. 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 2 minutes for a 30 x 30 mesh problem using 4 energy groups.
