Abstract

Telah dilakukan perhitungan matriks Pij serta distribusi fluks neutron di dalam geometri slab pada sel bahan bakar nuklir U-235 dan U-238 dalam kondisi homogen dan tidak homogen. Penelitian ini bertujuan untuk memperoleh nilai fluks skalar dan nilai Pij yang menggunakan Method of Characteristic (MOC). Besarnya fluks neutron dan nilai Pij bergantung pada penampang lintang bahan bakar nuklir, lebar region, jumlah region dan parameter input lainnya. Hasil penelitian ini secara umum telah sesuai dengan teori yaitu nilai Pij total pada beberapa region bernilai ≈ 1. Nilai Pij dan distribusi fluks neutron pada keadaan homogen lebih baik dan seragam dibandingkan pada keadaan tidak homogen, hal ini terlihat dari bentuk distribusi fluks pada slab sesuai dengan penelitian yang dilakukan oleh Karriem (2012)
