Description
Activation of the soil surrounding the ESS accelerator tunnel calculated by the MARS15 code is presented. A detailed composition of the soil, that comprises about 30 different chemical elements, is taken into account. Spatial distributions of the produced activity are provided in both transverse and longitudinal direction. A realistic irradiation profile for the entire planned lifetime of the facility is used. The nuclear transmutation and decay of the produced radionuclides is calculated with the DeTra code which is a built-in tool for the MARS15 code. Evaluated nuclear data for some of the soil components—Sr, Ce, Nd, Dy—at present can be found only in the ENDF/B-VII library. Therefore, radionuclide production by low-energy neutrons is calculated using the most recent data libraries, mostly ENDF/B-VII, included in the MCNP6 package.
