3. DESCRIPTION OF PROGRAM OR FUNCTION

General neutronics calculation including cell calculation with burn-up, core calculation for any type of thermal reactor. Core burn-up calculation and fuel management by an auxiliary code.

[ top ]

4. METHOD OF SOLUTION

Collision probability method, 1D and 2D Sn for cell calculation; 1D, 2D and 3D diffusion for core calculation.

[ top ]

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

20 regions for a
continuous energy resonance absorption calculation and 16 steps for cell burn-up.

[ top ]

6. TYPICAL RUNNING TIME

It depends on the number of energy group, geometry option, and with or without burn-up calculation.

[ top ]

7. UNUSUAL FEATURES OF THE PROGRAM

Flexible energy group structure in cell and core calculation. 13 types of cell geometries for collision probability method. Optional treatments for resonance absorption by table-look-up based on NR or IR, or the continuous energy cell calculation in dominant resonance energy range. Successive cell calculation to treat double heterogeneity.
