The paper describes the functionality and structure of a program package called CORIDA being developed for radiation safety analysis of legacy nuclear facilities and radioactive waste disposal sites. Results of such computations are heavily dependent on the emissive properties of radioactive wastes; that is why the program package includes a nuclide kinetics module. Neutron and photon transport is simulated using the TDMCC code. To simplify the pre-processing procedure in the program-specific format, the program package contains a special graphics editor and a data converter for problem geometry, materials and radiation sources. Results of testing the nuclide kinetics module and the program package as a whole are reported. Keywords: program package, radioactive wastes, nuclide kinetics, radiative transfer simulations, graphics editor, data converter, yield, dose rate.
