Sensitivity of reactor integral parameters to #betta##betta# parameter of resolved resonances of fertile isotopes and to the α values, in thermal and epithermal spectra

  • 1. Instituto Militar de Engenharia, Rio de Janeiro (Brazil)

Description

A sensitivity analysis of reactor integral parameter to more 10% variation in the resolved resonance parameters #betta##betta# of the fertile isotope and the variations of more 10% in the α values (#betta# sub(#betta#)/#betta# sub(f)) of fissile isotopes of PWR fuel elements, is done. The analysis is made with thermal and epithermal spectra, those last generated in a fuel cell with low V sub(M)/V sub(F). The HAMMER system, the interface programs HELP and LITHE and the HAMMER computer codes, were used as a base for this study. (E.G.)

Abstract (Portuguese)

Faz-se uma analise da sensitividade de parametros integrais do reator a variacoes de +10% nos parametros de ressonancia resolvida #betta# sub(#betta#) dos isotopos ferteis e a variacoes de +10% nos valores de α(#betta# sub(#betta#)/#betta# sub(f)) dos isotopos fisseis do combustivel de um reator tipo PWR. A analise e feita em espectros termicos e epitermicos, estes ultimos gerados em uma celula de combustivel com baixa razao V sub(M)/V sub(F). O sistema HAMMER1, com sua biblioteca basica, os programas interfaces HELP e LITHE e o codigo HAMMER, serviu como base para o estudo. (Autor)
