Abstract

Reaktor air didih atau boiling water reactor (BWR) merupakan reaktor yang memanfaatkan air sebagai media pendingin dan juga sebagai moderator. Penelitian ini mendesain reaktor air didih berbentuk modul atau Small Modular Reactor (SMR) berdaya 100MWth berbahan bakar Thorium Karbida (Th-U233-C), selongsong Silikon Karbida (SiC) dan pendingin air (H2O). Perhitungan neutronik dilakukan dengan mengunakan program SRAC versi 2006 dengan database nuklir JENDL 4.0. Hasil yang diperoleh menunjukkan bahwa reaktor air didih berbentuk modul dengan bahan bakar Thorium Karbida yang diberi tambahan Protaktinium-231 (Pa-231) sebanyak 6% menunjukkan hasil paling kritis. Reaktor mampu beroperasi selama 20 tahun tanpa pengisian ulang bahan bakar dengan maksimum faktor multiplikasi efektif (keff) 1,00392. Nilai maximum excess reactivity yang dihasilkan sangat kecil dibawah 1% yakni 0,39% ∆k/k dan densitas daya maksimum yang dihasilkan bernilai 59 watt/cc.
