Abstract [en]

To improve the effect of the concrete below 10 MeV where iron has resonances in the cross section, a new concrete have been developed. The PE-B4C-concrete utilizes hydrogen containing PE to thermalize the neutron and boron for in situ absorption. It is of utmost importance that the activation of the shielding material itself is well-understood, since it is planned to be used at the ESS. The first steps in this direction are shown the present study, in which concrete as well as reference aluminium samples are subject to XRF measurements to precisely determine the element content. This is compared to data sheets from the vender, and simulations are carried out to predict the sample activity. The samples are planned for insertion into the the Budapest Research Reactor, followed be activity and spectral measurements.
