Abstract

Telah dilakukan disain kode komputasi untuk Analisis Burnup pada Reaktor Pembiak Cepat menggunakan bahasa pemograman Delphi 7.0. Disain dirancang untuk geometri teras reaktor 3 dimensi XYZ yang berbentuk kubus (seimbang/balance, x = y = z) dengan menggunakan bahan bakar UN-PuN (Nitrida). Simulasi disain diawali dengan perhitungan densitas awal, dilanjutkan dengan penyelesaian persamaan difusi multigrup untuk mendapatkan faktor multiplikasi, distribusi fluks neutron, dan distribusi daya. Nilai fluks neutron digunakan untuk menghitung perubahan densitas nuklida dalam analisis burnup (susutan bahan bakar). Hasil perubahan densitas nuklida digunakan untuk menghitung nilai Breeding Ratio (BR) dan Burnup (B). Contoh dari hasil simulasi melalui kode komputasi yang didisain memperlihatkan perubahan densitas setiap interval waktu tertentu, selain itu nilai Breeding Ratio (BR) untuk 1 siklus (4 tahun) menurun, tetapi masih dalam rentang nilai BR > 1. Nilai Burnup untuk 1 siklus (4 tahun) meningkat seiring dengan banyaknya nuklida dalam bahan bakar yang berfisi (terjadi penambahan densitas nuklida dalam bahan bakar seperti 234U, 236U, 237Np, 238Np, 239Pu, 240Pu, 241Am, 243Am).
