Ítem Acceso Abierto Gaseous diffusion enrichment modular unit(2004-04-01) Juanicó, Luis Eduardo; Brasnarof, Daniel Oscar; Florido, Pablo Carlos; Bergallo, Juan Esteban; CNEA; INVAP do Brasil LTDA.; Juanicó, Luis EduardoA gaseous diffusion enrichment modular unit and gaseous diffusion enrichment plant, comprehending a gaseous diffusion enrichment unit of the enrichment cascade type, being an integrated module containing all the elements of the unit, with several flows of circulation with different enrichment degrees, comprehending an axial compressor in simultaneous work of compression of said flows, a diffuser with membranes. The diffused (enriched) fluid passes through to the compressor in another section to accomplish the following enrichment phase and the non-diffused flow outlet is connected to an injector to even the pressures and to recycle the depleted material. Said modular unit of isotopic enrichment integrates multiple enrichment phases to achieve a high separative efficiency by means of the internal recirculation of a fraction of the diffused fluid in each phase. The multiflow axial compressor is driven by a gas turbine and the outgoing gases of the turbine and the heat generated in the process are injected in a thermal cycle. In the center of the unit is a probe to perform non-destructive analysis. The gaseous diffusion enrichment plant comprehends said enrichment modular units connected in series and the numbers of the phases of one or more said units are different. An application of the present invention is its use for the isotopic separation of uranium hexafluoride in gaseous phase.Ítem Acceso Abierto Gaseous diffusion enrichment modular unit and gaseous diffusion enrichment plant(20020306) Juanicó, Luis Eduardo; Brasnarof, Daniel Oscar; Florido, Pablo Carlos; Bergallo, Juan Esteban; CNEA; INVAP do Brasil LTDA.; Juanicó, Luis EduardoGaseous diffusion enrichment modular unit and gaseous diffusion enrichment plant, comprehending a gaseous diffusion enrichment unit of the enrichment cascade type, being an integrated module containing all the elements of the unit, with several flows of circulation with different enrichment degrees, comprehending an axial compressor (1) in simultaneous work of compression of said flows, a diffusor (3) with membranes.

O fluído difundido (enriquecido) passa ao compressor em outra seção para realizar a seguinte etapa de enriquecimento e a saída de fluxo não difundido conecta-se a um injetor para nivelar as pressões e reciclar o material empobrecido. A referida unidade modular de enriquecimento isotópico integra múltiplas etapas de enriquecimento para conseguir um alto rendimento separativo mediante a recirculação interna de uma fração do fluído difundido de cada etapa. O compressor axial multifluxo é acionado por uma turbina de gás e os gases de saída da turbina e o calor gerado no processo são injetados em um ciclo térmico. No centro da unidade existe uma sonda para efetuar análise não destrutiva. A fábrica de enriquecimento por difusão gasosa, compreende ditas unidades modulares de enriquecimento conectadas em série e os números de etapas de 1 ou mais de ditas unidades é diferente. Uma aplicação da presente invenção é sua utilização para a separação isotópica do hexafluoreto de urânio em fase gasosa.
