3. NATURE OF PHYSICAL PROBLEM SOLVED

CONDOR-3 is a few group bi-dimensional lifetime program. The types of reactor regions which can be considered are - normal diffusion regions, non-diffusion or logarithmic regions in which a logarithmic derivative condition is given on the boundary, rodded regions which  simulate the control rod poison properly smeared. The types of considered poisons are - burnable poisons, poison diluted over the whole reactor according to the dilution factor theta, poison in the  rodded regions. The types of diffusion calculations are - straight Keff, dilution factor theta, poison in rodded region, boundary of a  rodded region.
The main differences of CONDOR-3 with respect to CONDOR-2 concern the following points: the depletion equations are solved mesh-wise instead of region-wise. The library of basic cross sections is still a microscopic library or a macroscopic library (to be used for non-lifetime calculations). However, one can use different basic microscopic libraries for different regions. Moreover, the basic microscopic library (or libraries) can be modified at each time step by the program itself by computational procedures which obviously must be set up bearing in mind the reactor type.

4. METHOD OF SOLUTION

The method of spatial nodal expansion and the five points finite difference method are coupled. By means of the spatial nodal expansion the program determines the eigenvalue of the reactor (Keff, theta, poison or boundary of a rodded region). By means of the finite difference method, the program improves the above calculation and the group flux spatial distribution.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

Maximum number of - harmonics - 100, if number of groups = 1 or 2
                                 85, if number of groups = 3
                                 72, if number of groups = 4
                    nodes along x - 100
                    isotopes - 50
                    burnable isotopes - 40
                    mesh points - 12000
                    polynomial coefficients - 2000

6. TYPICAL RUNNING TIME:  More than 30 minutes.

7. UNUSUAL FEATURES OF THE PROGRAM

The chains of burnable isotopes can be defined by the user without unjustified restrictions.
However, a standard set of isotopic chains is built into the code.
The isotopes can be assigned either constant self-shielding factors  or concentration dependent self-shielding factors.
