ARMP-02 documentation: Part 2, Chapter 9: PDQ7-E computer code manual: Volume 1, EPRI modifications to PDQ7-V2

PDQ7E V2 is a modified version of the PDQ7 Version 2 program released by Bettis Atomic Power Laboratory in 1972. PDQ7E V2 is a nuclear reactor analysis program which solves the neutron diffusion equations in one, two or three dimensions and also performs depletion calculations. Steady state solutions of the flux and power distributions and the reactivity are obtained. A specified interval of depletion may be input, resulting in the prediction of nuclide concentrations via the depletion equations. PDQ7E V2 is a few group program, i.e., up to five lethargy groups are permitted. The PDQ7E V2 program has been installed on the CDC and IBM computer systems using the EPRI Environmental Library Subroutines. Special EPRI capabilities have been installed
