A criticality assessment through user's routines in FLUKA

Abstract

In the present paper, a method to obtain the k_eff value using the FLUKA code is described. It took advantage of the chance to write user defined routines in the standard code. A new algorithm was implemented and tested on the simulation of a research nuclear reactor. Results pertaining to the estimation of k_eff and neutron fluence are in good agreement with the MCNP's ones.
