The FREEWARE program ChainSolver has been created as a tool for nuclear chain calculations. It takes into account both radioactive decays and possible neutron reactions (threshold ones,thermal neutron captures and neutron induced fission).

NKE is developed as a tool for detailed data on radionuclides properties retrieval.NKE data file contains nuclear constants and decay data for more than 2800 nuclides with atomic weights from 1 up to 293 (nuclear charge from 1 up to 118) and characteristics of chemical elements.
