Keywords:PHITS, activation calculation, uncertainty, nuclear data

DCHAIN-SP, the radionuclide build-up and decay code distributed alongside the PHITS particle transport code, is being updated with modern data libraries and calculation features, the most important being propagation of statistical uncertainties in its input data to the reported nuclide inventories, activities, decay heat, and gamma-ray spectra. These data library and feature updates will be detailed in this presentation.
