3. DESCRIPTION OF PROGRAM OR FUNCTION

NOTRAN/3D solves the neutron transport equation in three-dimensional XYZ geometry by the discrete nodal transport method. Source and eigenvalue problems can be solved. The input format for cross sections is the same as for ANISN. Multigroup cross section libraries such as DLC-37 and DLC75/BUGLE-80 can be used.

4. METHOD OF SOLUTION

NOTRAN/3D uses the discrete nodal transport method. Anisotropic scattering is treated using Legendre expansion.  The order of interior flux approximation is two. Plane or linear leakage approximation of surface flux is used.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

Maximum order of -
                 anisotropic scattering =  3
                 material compositions  = 20
                 energy groups          =  2
                 angular quadrature     =  8
                 zones                  = 20.
When coarse-mesh rebalancing is used, the maximum number of course meshes is 5 in each direction. If computer memory permits, some arrays can be enlarged to reduce the above restrictions.
