Description
The research reactors, of which the fuel elements are of MTR type, functions presently, almost in their majority with high U-235 enrichment. The fear that those fuel elements might generate a considerabLe proliferation of nuclear weapons rendered almost mandatory the conversion of highly enriched fuel elements to a low U-235 enrichment. As the IEA-R1 reactor of IPEN is operating with highly enriched fuel elements a study aiming at this conversion was done. The problems related to the conversion and the results obtained, demonstrated the technical viabilty for its realization. (E.G.)
Abstract (Portuguese)
Os reatores de pesquisas, cujos elementos combustiveis sao do tipo 'MTR', funcionam atualmente, quase que em sua maioria, com alto enriquecimento em U-235. O receio de que estes combustiveis propiciassem uma proliferacaO consideravEl de armamentos nucleares, tornou quase que obrigatoria a conversao dos elementos combustiveis altamente enriquecidos para baixo enriquecimento em U-235. Como o reator IEA-R1 do Instituto de Pesquisas Energeticas e Nucleares vinha operando com elementos altamente enriquecidos, houve a necessidade de se fazer um estudo para sua conversa Procura-se enfocar os problemas relativos a conversao e os resultados alcancados demonstrando a viabilidade tecnica para a sua realizacao.
