The activation of the biological shield is an important process for waste management considerations of nuclear facilities. The final activity can be estimated by modeling using the neutron flux density rather than the radiometric approach of activity measurements. Measurement series at the TRIGA reactor Vienna reveal that the flux density next to the biological shield is in the order of 109 cm−2 s−1 at maximum power; but it is strongly influenced by reactor installations. The data allow the estimation of the final waste categorization of the concrete according to the Austrian legislation.
► Neutron activation is an important process for the waste management of nuclear facilities. ► Biological shield of the TRIGA reactor Vienna has been topic of investigation. ► Flux values allow a categorization of the concrete concerning radiation protection legislation. ► Reactor installations are of great importance as neutron sources into the biological shield. ► Every installation shows distinguishable flux profiles.
