ABSTRACT

IPEN/CNEN-SP produces, for its IEA-R1 Research Reactor, MTR fuel assemblies based on U₃O₈-Al dispersion fuel type. Since 1985 a qualification program on these fuel assemblies has been performed. Average ²³⁵U burnup of 30 % and peak burnup of 50% was already achieved by these fuel assemblies. This paper presents some results acquire, by these fuel assemblies, under irradiation at IEA-R1 Research Reactor.
