Description

In order to use the existing light water reactor cell calculation codes for fluidized bed nuclear reactor having spherical fuel cells, an equivalence method has been developed. This method is shown to be adequate in calculation of the Dancoff factor. This method also was applicable in LEOPARD code and the results obtained in calculation of K∞ was compared with the obtained using the DTF IV code, the results showed that the method is adequate for the calculations neutronics of the fluidized bed nuclear reactor.

Abstract (Portuguese)

De modo a viabilizar a utilizacao de codigos computacionais ja existentes para reatores a agua leve nos calculos neutronicos do Reator Nuclear a Leito Fluidizado, que utiliza elemento combustivel na forma esferica, foi desenvolvido um metodo de equivalencia neutronica de uma celula esferica em cilindrica. Este metodo foi testado e mostrou-se adequado para o calculo do fator Dancoff. O metodo de equivalencia tambem foi aplicado no codigo LEOPARD e os resultados obtidos no calculo de K∞ foram comparados com os obtidos usando o codigo DTF IV, que e usado para projetos de reatores comerciais pelo Bhabha Atomic Research Centre (BARC), que calcula K∞ para celulas esfericas e cilindricas. Os resultados mostram que o metodo de equivalencia e adequado para os calculos neutronicos e que a versao do codigo LEOPARD utilizada e adequada no estudo deste novo conceito de reator nuclear, fornecendo resultados realisticos.
