Abstract

"UNIDADE MODULAR DE ENRIQUECIMENTO POR DIFUSãO GASOSA E FáBRICA DE ENRIQUECIMENTO POR DIFUSãO GASOSA". Compreendendo uma unidade de enriquecimento por difusão gasosa, do tipo de cascata de enriquecimento, sendo um módulo integrado, que contém todos os elementos da unidade, com vários fluxos de circulação com diferente grau de enriquecimento, compreendendo um compressor axial em trabalho simultâneo de compreensão de ditos fluxos, um difusor com membranas. 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.
