233 The High Temperature Reactor is quaIified for the thorium-uraruum fuel cycle. The conversion reactors of this type considered until today may be developed into breeders by the improvement of the reprocessing proce dure and the appIication of beryllium oxide as moderator material. The determination of the fast fis sion factor of beryllium oxide and the research of a pyrolytic procedure for the eIimination of the most important fis sion pro ducts are the top problems which should be solved within the frame of this development. In spite of the Iow breeding factor which is expected for the thorium uranium fuel cycle, a satisfying breeding proce~cc:ould be reached due to the high specific power of this reactor type. Resume Le reacteur a haute temperature se prete au cycle du combustible Thorium 233 Uranium Les convertisseurs de ce genre pris en consideration jusqu'a present peuvent etre developpes en surgenerateurs par une amelioration du procede de regeneration du combustible et par l'emploi de la glucine comme moderateur. La determination du facteur de fis sion rapide de la glucine ainsi que la recherche d'un procede pyrolitique pour la suppression des produits de fission les plus importants sont les problemes de premier ordre qui doivent etre resolus dans le cadre de ce developpement. Malgre le rapport de regeneration assez reduit qu'on attend du cycle Thorium-Uranium, une surgeneration satisfaisante peut etre esperee vu la grande puissance specifique de ce type de reacteur.
