TWOTRAN2; two-dimensional, multigroup transport in xy, rz, and r theta geometries. [CDC7600,6600; IBM360/195; FORTRAN IV]

Technical Report ·
OSTI ID:6365228
TWOTRAN2 solves the two-dimensional multigroup transport equation in (x,y), (r,theta), and (r,z) geometries. Both regular and adjoint, inhomogeneous and homogeneous (keff and eigenvalue searches) problems subject to vacuum, reflective, periodic, white or input-specified boundary flux conditions are solved. General anisotropic scattering is allowed and anisotropic inhomogeneous sources are permitted.CDC7600,6600;IBM360/195; FORTRAN IV; Five output units, five interface units (use of interface units is optional) and two system input/output units are required. A large bulk memory is desirable, but it can be replaced by disk, drum or tape storage..
