Description

An homogeneous model which simulates the stationary behavior of steam generators of PWR type reactors and uses the differential formalism of perturbation theory for analysing sensibility of linear and non-linear responses, is presented. The PERGEVAP computer code to calculate the temperature distribution in the steam generator and associated importance function, is developed. The code also evaluates effects of the thermohydraulic parameter variation on selected functionals. The obtained results are compared with results obtained by GEVAP computer code . (M.C.K.)

Abstract (Portuguese)

Apresenta-se um modelo homogeneo que, simula o comportamento estacionario de geradores de vapor de centrais nucleares do tipo PWR e usa o formalismo diferencial da teoria da perturbacao, para analise de sensibilidade de respostas lineares e nao lineares. Desenvolveu-se o programa computacional PERGEVAP para calcular a distribuicao de temperatura atraves do gerador de vapor e a funcao importancia associada. O codigo tambem avalia os efeitos da variacao dos parametros termohidraulicos sobre os funcionais selecionados. Os resultados obtidos sao comparados com os resultados obtidos pelo codigo GEVAP.
