摘要

The work presented in this paper describes a methodology for the parameterization of problem-dependent cross-section as a function of reactor parameters. The method is offered as an alternative to cross-section determination using few energy groups in PWR fuel element calculations. Another important advantage of the cross-section parameterization methodology is that once the cross-section data have been parameterized they can be stored and easily used in very simple computer devices for fast calculations. The results of comparison with direct calculations with the SCALE code system show excellent agreements. Although the methodology has been derived for a particular reactor configuration the method can be easily extended for other reactor configurations. It is suggested that the methodology presented here can also be extended to include reactor burn-up.
