3. DESCRIPTION OF PROBLEM OR FUNCTION
GENP-2 is a system of programs that use "generalized perturbation theory" to calculate the pertur- bations of reactor integral characteristics which can be expressed by means of ratios between linear or bilinear functionals of the real and/or adjoint fluxes (e.g. reaction rate ratios), due to cross section perturbations.

4. METHOD OF SOLUTION
GENP-2 consists of the following codes: DDV, SORCI, CIAP-PMN and GLOBP-2D.
DDV calculates the real or adjoint fluxes and power distribution using multigroup diffusion theory in 2-dimensions.
SORCI uses the fluxes from DDV to calculate the real and/or adjoint general perturbation sources.
CIAP-PMN reads the sources from SORCI and uses them in the real or adjoint generalised importance calculations (2 dimensions, multi- group diffusion).
GLOBP-2D uses the importance calculated by CIAP-PMN, and the fluxes calculated by DDV, in generalised perturbation expressions to calcu- late the perturbation in the quantity of interest.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM
DDV although vari- ably dimensioned has the following restrictions:
- max. number of mesh points 6400
- max. number of mesh points in 1-dimension 81
- max. number of regions 6400
- max. number of energy groups 100
- if power distribution calculated, product of number of groups and number of regions 2500.
The other programs have the same restrictions if applicable.

NEA-0605/01
The test cases supplied for the older version of this program system (NEA 0605/02) have been run by NEA-DB on IBM 3090 and VAX 8810 computers. Since no corresponding results were available for the present version, no comparing checks could be made. The following CPU times were required for the two test cases supplied:Case 1: DDV-2D: 44 sec (IBM); 77 sec (VAX)
SORCI: 4 sec (IBM); 14 sec (VAX)
CIAP-2D: 37 sec (IBM); 74 sec (VAX)
GLOBP-2D: 4 sec (IBM); 15 sec (VAX)
Case2: DDV-2D: 30 sec (IBM); 64 sec (VAX)
SORCI: 4 sec (IBM); 14 sec (VAX)
CIAP-2D: 34 sec (IBM); 74 sec (VAX)
GLOBP-2D: 4 sec (IBM).
