Description

The dynamic behaviour of the Brazilian uranium hexafluoride is analyzed in this paper, with regard to its radiolytic decomposition and to the action of catalysts on the reaction between UF6 and H2. The process gas (UF6/H2) was submitted in the laboratory of dynamic tests (DV-II) to similar conditions as those used in the enrichment plant presently being erected in Resende - RJ, 'First Cascade - FC'. The tests carried out have shown that the Brazilian UF6 has the same dynamic behaviour of the German UF6. It does not contain either any catalyst of the reaction between UF6 and H2 which could render it inappropriate for use in commercial plants. (author)

Abstract (Portuguese)

Neste trabalho e analisado o comportamento dinamico do hexafluoreto de uranio nacional em mistura com hidrogenio, no que se refere a sua decomposicao radiolitica e a acao de catalizadores da reacao entre UF6 e H2. O gas de processo (UF6/H2) foi submetido no laboratorio de testes dinamicos FV-III a condicoes semelhantes as utilizadas na usina de enriquecimento 'Primeira Cascata' - FC, ora em fase final de construcao em Resende. Os testes realizados permitem concluir que o UF6 produzido no Brazil possui o mesmo comportamento dinamico do UF6 alemao, nao contendo catalizadores da reacao entre UF6 e H2, que inviabilizem a sua utilizacao em usinas comerciais.
