Description

A comparison between the TRAC -PD2 code calculations and results from the CANON experiment is presented. The CANON experiment simulates the loss of coolant accident through the depressurization of a horizontal tube containing water at different temperatures. The experiment consist of the instantaneous rupture at one end of the tubing and the corresponding pressure and void fraction measurements during the transient. The comparison shows that the TRAC-PD2 code predicts satisfactorily the pressure and void fraction evolution in the CANON experiment. (F.C.)

Abstract (Portuguese)

O Codigo TRAC (Transiente Reactor Analysis Code), desenvolvido no Laboratorio Nacional de Los Alamos, visa analisar acidente postulados em reatores nucleares refrigerados a agua leve. A versao TRAC-PD2, utilizada neste trabalho, dispoe de uma apurada modelagem da dinamica do escoamento atraves do modelo de dois fluidos que e baseado nas equacoes de conservacao da massa, quantidade de movimento e energia para o liquido e vapor permitindo, assim, considerar o desequilibrio mecanico e termico entre fases. Este trabalho apresenta a comparacao do Codigo TRAC-PD2 com os resultados da experiencia CANON, a qual simula um Acidente de Perda de Refrigerante Primario - APRP (LOCA) atraves da despressurizacao de um tubo horizontal contendo agua a diferentes temperaturas. A experiencia consiste na ruptura instantanea de um dos lados da tubulacao, sendo efetuadas medidas de pressao e de fracao de vazio durante o transiente. Os resultados desta comparacao mostram que o Codigo TRAC-PD2 prediz satisfatoriamente a evolucao da pressao e da fracao de vazio obtida na experiencia CANON. (Autor)
