Penelitian ini menggunakan bahan bakar thorium-232 dan uranium-233. Perhitungan dilakukan menggunakan kode ASMBURN pada program SRAC, dengan menentukan pengayaan bahan bakar, radius sel, menganalisis densitas atom setelah burn up, penambahan burn up, dan perubahan daya linear. Hasil perhitungan yang diperoleh menunjukkan nilai pengayaan bahan bakar yang efisien yaitu pada penngayaan 4%, dengan radius sel bahan bakar sebesar 0,3902 cm, cladding 0,4508 cm, dan moderator sebesar 0,5586 cm. Nilai densitas atom Th232 mengalami penurunan untuk setiap periode burn up, sementara densitas atom U233, U235, dan Pu239 mengalami kenaikan. Nilai keff akan mengalami penurunan seiring dengan penambahan burn up dan daya linear yang lebih besar. Kata kunci: ASMBURN, burn up, SCWR, thorium. The research about the calculation of burn-up model of the hexagonal assembly in SCWR reactor using thorium as fuel materials has been done. This research uses thorium-232 and uranium-233 as fuel materials. Calculations were performed using the ASMBURN code in the SRAC program, by determining fuel enrichment, cell radius, analyzing atomic density after burn up, increasing burn up level, and change of linear heat. The calculation results obtained show the value of efficient fuel enrichment at 4% enrichment, with 0.3902 cm of fuel cell radius, 0.4508 cm of cladding, and 0.5586 cm of moderator. The atomic density of Th232 decreased for each burn-up period meanwhile, the atomic density of U233, U235, and Pu239 increased. The keff value will decrease along with the addition of burn up and greater change of linear heat. Key words: ASMBURN, burn up, SCWR, thorium. date: 2021-12-14 date_type: published publisher: Fakultas Matematika Ilmu Pengatahuan Alam place_of_pub: UNIVERSITAS LAMPUNG citation: MEY PUJI ASTUTI, 1417041056 (2021) PERHITUNGAN BURN UP MODEL ASSEMBLY HEKSAGONAL PADA REAKTOR SCWR MENGGUNAKAN BAHAN BAKAR THORIUM.
