Schloesser, J.

The Dragon Project has just started to study the burn-up of Thorium-Uranium systems in a large power reactor. In order to determine core compositions of interest earlier results, obtained in studies by the U.K.A.E.A. are used as a basis for the present investigations. In this paper equilibrium compositions are discussed which can be achieved either by a complete replacement of the core or by a continuous charge discharge operation when the fuel is reprocessed. These two simplified recharge methods were chosen because the uncertainty in the fuel fabrication costs is such that a more detailed fuel cost study involving partial reloading schemes appears to be inappropriate at present. On the other hand a wide range of fuel production costs has been considered and core compositions leading to minimum fuel costs under various conditions have been established.
