AbstractAbstract
[en] A model of thermohidraulic simulation, for steady state, considering the secondary flow divided in two parts individually homogeneous, and with heat and mass transferences between them is developed. The quality of the two-phase mixture that is fed to the turbine is fixed and, based on this value, the feedwater pressure is determined. The recirculation ratio is intrinsically determined. Based on this model it was developed the GEVAP code, in Fortran-IV language. The model is applied to the steam generator of the Angra II nuclear power plant and the results are compared with KWU'S design parameters, being considered satisfactory. (Author)

Apresenta-se o desenvolvimento de um modelo de simulacao termohidraulica, para regime permanente, geradores de vapor tipos tubos em 'U' invertido, considerando-se o escoamento secundario dividido em duas partes, individualmente homogeneas, e com troca de calor e massa entre elas. O titulo da mistura bifasica que alimenta a turbina e fixado e a pressao da agua de alimentacao e determinada em funcao dele. A razao de recirculacao e intrinsicamente determinada. Baseado neste modelo, desenvolveu-se o programa GEVAP, em linguagem Fortran-IV. O modelo e aplicado ao gerador de vapor da central de Angra II e os resultados obtidos sao comparados com os dados de projeto da KWU, sendo considerados satisfatorios. (Autor)Original Title
