Keywords:decommissioning, activation estimation, DORT, group structure, neutron flux, JPDR

Activation estimations for decommissioning depend on neutron spectra used in calculations. We studied how neutron spectra and activation inventories varied corresponding to neutron group structures in DORT calculations with a simplified JPDR model.
