[en] Since 1978 the CNEA ECBE project has been involved in the development of dispersion fuel plates with four types of fuel materials -- UAl_x, U₃O₈, U₃Si, and U₃Si₂ -- to be used in low enriched (LEU < 20% ²³⁵U) fuel elements for research reactors. Miniplates with these fuel materials were manufactured at CNEA and were irradiated in the ORR in three series of irradiations as part of the RERTR miniplate irradiation program. The first irradiation contained U₃O₈ and UAl_x fuel, the second U₃O₈, UAl_x and U₃Si, while the third irradiation test consisted of six U₃Si₂ miniplates and one U₃Si miniplate. This third test is the subject of this paper. The present results compare favorably with other irradiations performed in the RERTR program^1,2 showing in particular the excellent behavior of the U₃Si₂. The overall data accumulated support the qualification of the CNEA fabrication techniques. 5 refs., 13 figs., 3 tabs
