    Abstract

    In Tore-Supra, neutron productions up to 1020 neutrons/year are expected. Calculations based on 1-D and 3-D codes have been made before the assembly phase. A strategy has been established to reconcile high neutron levels with the needs of an experimental device, i.e. access to the tokamak. Operation at low power (8.5 1016 neutrons) has allowed an initial set of measurements, which has been compared to the calculations. Quite good agreement is observed, especially for fast neutrons. A difference for slow neutrons is attributed to a small quantity of boron added in the concrete wall surrounding the experiment and to safety factors in the computations.
