    Abstract

    Activation of concrete in wall depends on the incident neutron energy spectrum, composition of the concrete, depth from the wall surface and other parameters. Dependency on the neutron energy spectrum was evaluated by the SCALE system calculations on each important reaction for the activation of concrete. The activation of a concrete wall can be estimated by summing the values of activities for each reaction based on the data of composition of the concrete and the incident neutron energy spectrum.
