3. DESCRIPTION OF PROGRAM OR FUNCTION

TP2 is a transport theory code, developed to determine reactivity effects and kinetic parameters such as effective delayed neutron fractions and mean generation time by applying the usual perturbation formalism for two-dimensional geometry.

[ top ]

4. METHODS

Direct and adjoin angular dependent neutron fluxes are read from an interface file (INTFAC). Multigroup cross sections are supplied in the SIGMN-block. Two-perturbation options are included in TP2: a) the usual first order perturbation theory to determine the prove reactivities, and b) assuming there are available direct fluxes for the unperturbed reactor system and adjoint fluxes for the perturbed system, the exact reactivity effect induced by the perturbation can be determined by an exact perturbation calculation.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

The IBM VS Fortran compiler is used, with LANGLVL(66). The interface fiel INTFAC and the SIGMN file have to be copied by means of the IBM utility IEHMOVE to avoid loss of data.

6. TYPICAL RUNNING TIME

Execution of the program with the sample input takes about 11 seconds of CPU time on the IBM 3033.
