Abstract

Penampang lintang makroskopik memiliki peranan penting dalam menghitung transport neutron yang terjadi pada reaktor nuklir. Hasil penampang lintang digunakan untuk menghitung nilai distribusi fluks neutron yang terjadi di teras reaktor. Penelitian ini menampilkan nilai penampang lintang makroskopik total dari sebuah sel bahan bakar nuklir. Tahap awal dilakukan dengan menentukan bahan bakar yang digunakan yaitu uranium-plutonium nitride, kemudian fraksi massa dan fraksi volume, cladding, dan pendingin. Perhitungan penampang lintang makroskopik ini dilakukan dengan metode simulasi komputer menggunakan bahasa pemrograman Borland Delphi 7.0. Program yang digunakan adalah program homogenisasi sel dengan data library JFS-3-J33 dari JAEA (Japan Atomic Energy Agency) yang menghasilkan nilai penampang lintang makroskopik total untuk 70 grup energi. Hasil analisis menunjukan bahwa pola penampang lintang makroskopik total untuk nuklida uranium dan plutonium pada energi tinggi (unresolved resonance) mengalami tumpang tindih (overlap) dalam sel bahan bakar nuklir.
