Abstract

Analisis neutronik pada Gas Cooled Fast Reactor (GCFR) dengan variasi strategi shuffling bahan bakar telah dilakukan dengan pengaturan awal daya reaktor 550 MWTh dan umur 100 tahun menggunakan input bahan bakar uranium alam tanpa pengayaan. Bahan bakar pada pada teras reaktor dibagi atas 10 region, dengan label region 1 hingga region 10. Setiap region bahan bakar mengalami perbedaan lama proses burnup dan perbedaan densitas nuklida. Variasi strategi shuffling dilakukan dengan cara menyusun masing-masing region bahan bakar secara acak dari region 1 hingga 10. Pada penelitian ini dirancang 4 macam variasi strategi shuffling bahan bakar arah radial. Shuffling bahan bakar dilakukan sekali dalam 10 tahun bersamaan dengan periode refueling. Perhitungan dilakukan dengan metode komputasi menggunakan kode SRAC dengan input data nuklir dari JENDL-32 Library dengan model teras silinder 2D R-Z. Hasil analisis menunjukkan bahwa berdasarakan nilai faktor multiplikasi efektif, variasi strategi shuffling memenuhi kriteria desain reaktor. Strategi shuffling dengan pengaturan region bahan bakar berdensitas fisil tertinggi yang didekatkan dengan region bahan bakar berdensitas fisil rendah menghasilkan densitas 239Pu yang tinggi.
