Abstract

Analisis kekritisan Sodium-Cooled Fast Reactor (SFR) berdasarkan variasi bahan bakar telah dilakukan. Variasi bahan bakar yang digunakan adalah MOX, UN-PuN, dan U-Zr. Reaktor ini menggunakan natrium sebagai pendingin dan parameter yang diamati adalah faktor multiplikasi (keff )pada teras reaktor. Penelitian ini dilakukan secara simulasi komputasi meggunakan kode SRAC (Standard Thermal Reactor Analysis Code System) dengan JENDL-32 sebagai library. Teras reaktor dibagi menjadi 10 region arah radial.  Pada awal operasi reaktor, masing-masing region diisi dengan bahan bakar uranium alam.  Setelah 10 tahun pembakaran, hasil burn up pada region 1 di shuffling ke region 2, hasil region 2 di shuffling ke region 3 dan seterusnya sampai hasil burn up di region 9 di shuffling ke region 10, hasil burn up region 10 dikeluarkan dari teras reaktor dan pada region 1 akan diisi dengan bahan bakar yang baru. Hasil penelitian menunjukkan bahwa bahan bakar MOX dan U-Zr memilki nilai keff  yang paling optimal digunakan pada reaktor SFR.

Kata kunci: faktor multiplikasi keff , periode burn up, program SRAC, strategi shuffling
