Modular system of nuclear reaction codes for advanced modeling of nuclear reactions using various theoretical models. It consists of a number of FORTRAN codes, input parameter libraries, and experimental data library (EXFOR/CSISRS) - operated through the Graphic User Interface (GUI).

EMPIRE is intended to be a general, flexible, and easy to use tool for basic research and evaluation of nuclear data. It offers a possibility of combining several theoretical approaches, choosing among alternative input parameters and calculating extended set of observables in a single run. Nuclear data evaluation is facilitated by the ENDF-6 formatting, file verification and graphical comparison with experimental data.
