Abstract

Banyak perangkat kritik dibangun untuk memenuhi kebutuhan studi fenomena kecelakaan kritikalitas pada larutan fisil di fasilitas daur bahan bakar nuklir. Salah satu diantaranya adalah perangkat kritik SCAMP. Di perangkat ini dikerjakan eksperimen kritikalitas menggunakan bejana silindris stainless steel berisi larutan plutonium- uranium nitrat (Pu+U nitrat). Sebanyak 7 eksperimen didemonstrasikan dengan reflektor air di semua sisi permukaan bejana larutan kecuali di bagian atas bejana. Makalah ini membahas simulasi transport Monte Carlo MCNP5 dalam eksperimen kritikalitas larutan Pu+U nitrat dengan reflektor air dan polyethylene. Simulasi MCNP5 dengan pustaka ENDF/B-VI memberikan hasil yang paling dekat dengan data eksperimen terutama pada kasus A untuk varian geometri 4. Dibandingkan pustaka ENDF/B-V, perhitungan kritikalitas dengan pustaka ENDF/B-VI memberikan hasil lebih dekat dengan perhitungan MONK dimana bias perhitungannya < 0,44%, khususnya pada kasus A namun pada kasus B dan C simulasi MCNP5 dengan pustaka ENDF/B-V memberikan hasil dengan kecenderungan lebih baik dibandingkan pustaka ENDF/B-VI dengan bias perhitungan < 2,67% dan < 1,13%. Secara keseluruhan dapat disimpulkan bahwa MCNP5 telah menunjukkan reliabilitasnya dalam simulasi kritikalitas larutan Pu+U nitrat.
