Description

In this paper some details of a simplified model for transient analysis of pool type liquid metal fast reactors are presented. This model, which calculates the transient mass flow rate and sodium temperatures, can be used for adequate components set up within reactor vessel, that obey structural requirements. The details presented are the intermediary heat exchanger and the pump models, and a mathematical method for the solution of coupled differential equations. These models and method were verified by illustractive calculations of two transients in a typical fast reactor with hot pool, which were compared with the results of other researchers. (author)

Abstract (Portuguese)

Neste trabalho sao apresentados alguns detalhes de um modelo simplificado para analise de transientes em reatores rapidos de metal liquido tipo piscina. Esse modelo calcula a vazao transiente e as temperaturas do sodio, podendo ser utilizado para o adequado arranjo dos diversos componentes dentro do vaso, que satisfacam requisitos estruturais. Os detalhes apresentados sao o modelo do trocador de calor intermediario, o modelo da bomba e um metodo matematico de solucao das equacoes diferenciais acopladas. Esses modelos e metodos foram verificados atraves de calculos ilustrativos de dois transientes em um reator rapido tipico com piscina quente, que foram comparados com resultados de outros pesquisadores.
