Abstract

The European (Reactor) Accident Code EAC2 uses the neutron transport program HEX-NODYN which applies response matrix elements (generalised albedoes, including side scattering and transmission) in order efficiently to reduce the computer running time. In the case of a large reactor accident, much material in the core (coolant, fissile and structure material) gets shifted, strongly changing the response matrix elements. It would be very time-consuming to recalculate them at frequent intervals, but it seems both necessary and physically possible to interpolate them within a prefixed mesh in dependence of the main partial densities. Formulae for such an interpolation are proposed and discussed.
