The nuclear spectroscopy studies at the Holifield Radioactive Ion Beam Facility (HRIBF) at Oak Ridge National Laboratory concentrate on nuclei far from beta stability. The recent results include the information on the structure of nuclei next to three doubly-magic nuclei 100Sn [1], 132Sn [2] and 78Ni [3,4,5]. The observed single particle levels and decay processes help to analyze the evolution of nuclear structure in these exotic regions of nuclei. The large beta-delayed neutron branching ratios observed for precursors near 78Ni are also important for the analysis of the processes occurring in nuclear fuels and during the rapid neutron capture process in hot stars. The construction of new detectors improving our discovery potential at the HRIBF will be presented as well as Oak Ridge recent contribution [6] and planned detector upgrades for the studies of new super heavy nuclei.
