Description

A ten stage pilot plant to study experimentally dynamic behavior of a uranium enrichment plant based on separation nozzle process was developed and constructed at Karlsruhe Nuclear Research Center. This installation was transfered to the Development Center of Nuclear Technology (CDTN) of Nuclebras in Belo Horizonte, Brazil. The separation elements installed have a new design with higher efficiency, Known as double-deflections system. The power plant has been used to improve the control method and to prove the stability of separation nozzle cascade under pertubations produced artificially. The stabilization process of UF6 quantity in cascade by UF6 inventory regulation at bottom stage will have practication in the First Cascade, in Rezende, RJ, Brazil and may be uded i emonstration plant. The experimental results have shown to be comparable with those obtained by computer simulation. (Author)

Abstract (Portuguese)

Foi desenvolvido e construido no Centro Pesquisas Nucleares de Karlsruhe uma usina piloto de 10 estagios para estudar experimentalmente o compportamento dinamico de uma usina de enriquecimento de uranio baseado noo processo de jato centrifugo. Esta instalacao foi transferida para o Centro de Desenvolvimento de Tecnologia Nuclear da Nuclebras, em Belo Horizonte de acordo com as previsoes do Acordo Nuclear Brasil-Alemanha. Os elementos de separacao instalados possuem uma nova geometria, de maior eficiencia denominada sistema de deflexao dupla. A usina esta sendo usada para aperfeicoar a metodologia de controle e para comprovar a estabilidade da cascata de jato centrifugo, sob efeito de pertubacoes provocadas artificialmete. O processo de estabilizacao da quantidade de UF6 na cascata atraves da regulagem do inventario de UF6 no estagio-petera aplicacao pratica na Primeira Cascata, construida em Rezende, RJ, e podera ser usada na usina de demonstracao. Os resultado experimentais tem-se demonstrado comparaveis aqueles obtidos por meio de codigos de simulacao em computador. (Autor)
