Abstract EN
In a fast reactor, we evaluated a new core concept that prevents severe recriticality after whole-scale molten formation in a severe accident.
A core concept in which Duplex pellets including neutron absorber are loaded in the outer core has been proposed.
Analysis by the continuous energy model Monte Carlo code MVP using the JENDL-4.0 nuclear data library revealed that this fast reactor core has large negative reactivity due to fuel melting at the time of a severe accident, so that the core prevents recriticality.
Regarding the core nuclear and thermal characteristics, the loading of Duplex pellets including neutron absorber in the outer core caused no significant differences from the normal core without Duplex pellets.
