Abstract

A reactor noise approach has been successfully performed at the IPEN/MB-01 research reactor facility in order to determine experimentally the effective delayed neutron parameters βi and λi in a six-group model and the point kinetic equations. The theory/experiment comparison shows that for the abundances the JENDL3.3 presents the best performance while for the decay constants the revised version of ENDF/B-VI.8 shows the best agreement. As a by-product and a consistency check, the βeff parameter was obtained without the need of the Diven factor and the power normalization and it is in excellent agreement with independent measurements. Also, the βeff result is independent on the nuclear data library used in the fitting procedure. The reflector effect appears to be important only for frequencies larger than βeff/Λ, and the results for the kinetic parameters are almost the same as for the non-reflected case.
