Telah dilakukan penelitian tentang pengaruh geometri teras terhadap kinerja neutronik pada reaktor pembiak cepat dengan siklus bahan bakar tertutup. Penelitian dilakukan melalui simulasi komputasi dengan memvariasikan geometri teras untuk reaktor pembiak cepat berpendingin logam cair (Pb-Bi) dengan bahan bakar UN-PuN (Nitrida) yang beroperasi selama 20 tahun. Analisis
dilakukan terhadap hasil pengamatan perubahan harga faktor multiplikasi neutron (keff), perubahan nilai Burnup, perubahan nilai Breeding Ratio, dan perubahan densitas bahan fertil dan fisil di dalam teras reaktor. Dari keseluruhan model teras reaktor yang diamati, model G5 (Z>>X) memberikan hasil yang terbaik dengan mempertahankan harga keff dalam batas toleransi reaktifitas ($) ± 0,05 selama 13 tahun. Nilai breeding ratio (BR) untuk seluruh model teras masih dalam rentang yang diharapkan (BR>1), namun nilai BR paling baik diberikan oleh model teras G1 (Z<<X). Nilai burnup untuk keseluruhan model meningkat seiring dengan banyaknya nuklida yang berfisi di dalam teras reaktor dan yang paling baik diberikan oleh model teras G1. Beberapa nuklida baru hasil transmutasi bahan bakar muncul di dalam teras reaktor, contohnya 241Am.
