Abstract

Analisis neutronik Super Critical Water Reactor (SCWR) menggunakan simulasi komputasi program SRAC telah dilakukan. Reaktor ini menggunakan air ringan (H2O) sebagai pendingin. Analisis neutronik SCWR dilakukan dengan memvariasikan jenis bahan bakar, yaitu: uranium-plutonium nitrit (UN-PuN), uranium-plutonium karbit (UC-PuC) dan mixed oxide (MOX). Diameter teras dibagi menjadi 10 region dalam arah radial. Reaktor ini menggunakan strategi shuffling, agar reaktor dapat beroperasi menggunakan uranium alam. Masing-masing region diisi dengan bahan bakar yang sudah dibakar dan ditempatkan di dalam teras reaktor dengan konfigurasi tertentu dan uranium alam dibakar dalam jangka waktu 100 tahun. Setelah 10 tahun waktu operasi, bahan bakar di region 1 di pindahkan ke region 2, region 2 di pindahkan ke region 3 begitu seterusnya sampai bahan bakar di region 10 dikeluarkan dari teras reaktor dan region 1 diisi bahan bakar baru. Dari hasil simulasi didapatkan bahwa pada desain teras dengan bahan bakar UN-PuN dan MOX menghasilkan nilai faktor multiplikasi (keff) dan level burn up yang paling optimal.
