[en] The Heavy-Section Steel Technology (HSST) Program, supported by the US Nuclear Regulatory Commission, has completed the Series 5 (HSST5) irradiation experiments. Twelve capsules which contain metallurgical test specimens have been irradiated at the Oak Ridge Research Reactor located at the Oak Ridge National Laboratory. These capsules have been disassembled, internal dosimeters have been analyzed, and exposure parameters are presented for each irradiation test specimen. This report describes the computational methodology for the least-squares adjustment of the dosimetry data with neutronics calculations, and it presents exposure parameters at each test specimen location for the fluence rate greater than 1.0 MeV, fluence rate greater than 0.1 MeV, and displacements per atom. The specific activity of each dosimeter at the end of irradiation is listed in the Appendix
