N2 - A Mixed-Spectrum Reactor (MXR) is proposed as an alternative design to typical sodium-cooled long-lived fast reactors. Moderating material is locally inserted into the outer core region, and assemblies are shuffled once throughout their lifetime to ensure all fuel rods are exposed to both the thermal and fast spectra within the core. The final core outline maintains a long-lifetime of up to 25 years, while improving the proliferation resistance of the reactor. Peak neutron fast fluence at the clad is also reduced to approximately 4xl023n/cm2, close to the range where experimental data is available. The main tradeoffs of the MXR design relative to the original fast configuration were higher fuel resources requirement, a larger core volume, a larger reactivity swing, and the reliance on shuffling once during the operating lifetime of the core.
