Description
Summary:This paper is devoted to the test case for ALLEGRO MOX pin modeling using Serpent and ATHLET codes for coupled neutronics - thermal hydraulics coupled calculation. This research can be considered highly actual as ALLEGRO is the demonstrator of the Gen IV reactors and it should show the possibilities of the fast gas cooled reactors. In this paper, coupling scheme and the basic steps of the calculation, Serpent and ATHLET models of the MOX fuel pin divided into ten axial layers, and the calculated axial power distribution for all iterations are introduced. The auxiliary programs responsible for data processing are written in Python and Fortran languages.
