Abstract

Desain Neutronik Reaktor Cepat Berpendingin Helium 900 MWth bahan bakar Thorium Mix Oxide telah dilakukan. Dibutuhkan penambahan bahan bakar fisil Pu239 karena thorium alam tidak memiliki isotop fisil. Perhitungan dilakukan menggunakan simulasi kompu-tasi dengan program SRAC. Reaktor ini menggunakan Skema Burnup MCANDLE arah Radial dengan membagi teras reaktor menjadi 10 bagian. Setelah 10 tahun periode burn up, bahan bakar di shuffling secara radial dari bagian 1 ke bagian 2, bagian 2 ke bagian 3, begitu seterus-nya sampai bahan bakar di bagian 9 di-shuffling ke bagian 10 sehingga bahan bakar bagian 10 dikeluarkan dari teras reaktor dan bahan bakar baru ditempatkan di bagian 1. Hasil perhitun-gan menunjukkan bahwa komposisi bahan bakar 86% Th dan 14% Pu239 dalam keadaan kritis sampai pada tahun ke 4 ditunjukkan dengan nilai keff 1,012 dengan reaktivitas 0,0119. The Neutronic Design of a 900 MWth Helium Cooled Fast Reactor fueled by Thorium Mix Oxyde has been carried out. The addition of fissile fuel Pu239 is needed because natural thorium has no fissile isotopes. Calculations are performed using computational simu-lations with the SRAC program. This reactor uses the Radial direction MCANDLE Burnup Scheme by dividing the reactor core into 10 parts. After a 10 year burn-up period, the fuel is shuffled radially from section 1 to section 2, section 2 to section 3, and so on until the fuel in section 9 is shuffled to section 10 so that section 10's fuel is removed from the reactor core and new fuel is placed in section 1. The calculation results show that the fuel composition of 86% Th and 14% Pu239 is in a critical state until the 4th year is indicated by a keff value of 1.012 with a reactivity of 0.0119.
