AbstractAbstract
[en] 1 - Nature of physical problem solved: TDA (Time-Dependent ANISN) solves the one-dimensional time- dependent Boltzmann transport equation for neutrons and/or gamma- rays in slab, sphere or cylindrical geometries. Delayed neutron and other time-dependent effects are not considered in the present version. A choice of two types of sources and one initial condition specification is given (A. Space and energy distributed source with a step function time distribution. B. Analytical first collision source). 2 - Method of solution: TDA is based on the steady-state SN code ANISN for reasons of stability and generality. The weighted difference equations are used. 3 - Restrictions on the complexity of the problem: Limited only by available main storage
