3. DESCRIPTION OF PROGRAM OR FUNCTION

DNTM/R2D solves the neutron transport equation in two-dimensional X-Y geometry by the discrete nodal transport method. Source and eigenvalue problems can be solved. As compared to the two-dimensional nodal transport code DNTM/2D, the following new improved features are included:
- Anisotropic scattering is considered. The order of anisotropic
  scattering is from P0 to P3.
- The cross section input format is the same as for ANISN. Multi-
  group cross section libraries such as DLC-37 and DLC-BUGLE-80 can
  be used.

4. METHOD OF SOLUTION

DNTM/R2D uses the discrete nodal transport method. Anisotropic scattering is treated using Legendre expansion.  Order of interior flux approximation is 2. Plane leakage approximation of surface flux is used.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

Maximum number of -
        anisotropic scattering order =  3
        material composition         = 20
        energy groups                =  2
        angular quadrature           =  8
        zones                        = 30
When coarse-mesh rebalancing is used, the maximum number of coarse meshes is 12 in each direction. If the computer permits some arrays  can be enlarged to reduce the above restrictions.
