24th International Conference on Nuclear Energy for New Europe (NENE), Portoroz, Slovenya, 14 - 17 Eylül 2015
In this study, computational results of burnup dependent full core neutronic analysis of Pebble Bed Modular Reactor (PBMR) are presented. The calculations were performed by the MCNP-4b and BURN-HUNEM codes. BURN-HUNEM code was developed and utilized to perform depletion calculations using the cross section data generated by MCNP-4b to include double heterogeneity effect on neutronic parameters. The results for equilibrium cycle core composition and burnup were presented for once-through-then-out (OTTO) and Mehrfach-DUrchLauf (MEDUL) i.e., multi-pass, fuel cycle strategies.
