3. DESCRIPTION OF PROBLEM OR FUNCTION

CLUB is an integral transport theory code to calculate fluxes, reaction rates and few-group condensed cross sections for cylindricalized PHWR lattice cells. For a specified buckling, it computes keff using few-group diffusion theory in fundamental mode. There is also an option to calculate these quantities as a function of burnup.

4. METHOD OF SOLUTION

There are basically two options for solving the integral equation. In the first option, the integral transport equation is solved by the combination of the small scale Pij method  and the large scale interface current technique. At each region interface, the angular flux is expanded separately in the incoming and outgoing direction. Up to three terms can be considered in this  expansion. In the second option, the complete Pij method is used for the cylindricalized lattice cell.

The calculations are performed in 27 groups for which the cross sections are derived from the 69-group WIMS library by condensing them into 27 groups by using a typical spectrum of PHWRs.

The first order differential burnup equations can be solved by either the trapezoidal rule or the Runge-Kutta method.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

The program considers the same number of zones in each ring. Furthermore, the fuel pin in each ring should be of the same type.

6. TYPICAL RUNNING TIME

The CPU time for a problem is of the order of 6 minutes on PRIME-450 if the problem is solved by the first option  with one-term expansion for the angular flux at region interfaces.
