ABSTRAK
STUDI MODEL BENCHMARK MCNP6 DALAM PERHITUNGAN REAKTIVITAS BATANG KENDALI HTR-10. Dalam operasi reaktor nuklir, sistem batang kendali memainkan peranan yang sangat penting karena didesain untuk mengendalikan reaktivitas teras dan memadamkan reaktor. Nilai reaktivitas batang kendali harus diprediksi secara akurat melalui eksperimen dan perhitungan. Makalah ini mendiskusikan model Benchmark dalam perhitungan reaktivitas batang kendali reaktor HTR-10. Perhitungan dikerjakan dengan program transport Monte Carlo MCNP6 dan pustaka data nuklir energi kontinu ENDF/B-VII. Hasil perhitungan memperlihatkan prediksi MCNP6 memiliki kesesuaian yang cukup baik dengan pendekatan difusi maupun model Monte Carlo yang diestimasi China untuk reaktivitas sepuluh batang kendali fully in di teras penuh (problema Benchmark B3.1 dan B4.1). Simulasi MCNP6 memperlihatkan hasil yang kurang menguntungkan dalam kasus reaktivitas satu batang kendali fully in di teras penuh (problema Bechnmark B3.2), namun sebaliknya mendemonstrasikan akurasinya yang paling tinggi di teras inisial (problema Benchmark B4.2). Hasil-hasil ini menyimpulkan bahwa model MCNP6 yang digunakan dalam perhitungan reaktivitas batang kendali HTR-10 dapat diaplikasikan untuk analisis fisika teras reaktor pebble bed lainnya.Keywords
