Abstract

Telah dilakukan simulasi perhitungan untuk analisis pengaruh berbagai bahan pendingin jenis logam cair terhadap kinerja termalhidrolik pada reaktor cepat dengan bahan bakar UN-PuN.  Perhitungan dilakukan terhadap desain reaktor dengan geometri teras berbentuk kubus 3D dengan ukuran 80 x 80 x 80 cm. Optimasi desain reaktor dilakukan untuk variasi empat jenis bahan pendingin logam cair yaitu, Na, NaK, Pb dan PbBi. Tinjauan dilakukan terhadap parameter-parameter termalhidrolik yang meliputi distribusi temperatur teras dan penurunan tekanan sistem. Simulasi diawali dengan perhitungan difusi multigrup yang menghasilkan distribusi fluks neutron, faktor multiplikasi neutron dan distribusi densitas daya. Perhitungan termalhidrolik dilakukan terhadap  masing-masing bahan pendingin pada laju alir awal 3000 kg/s.  Kemudian dilakukan pengaturan hingga diperoleh kondisi laju alir yang sesuai untuk masing-masing performa pendingin. Hasil simulasi menunjukkan bahwa pendingin Pb dan PbBi memberikan kinerja termalhidrolik yang baik pada laju alir 3000 kg/s, sedangkan pendingin Na dan NaK menunjukkan kinerja termalhidrolik baik pada rentang laju alir massa pendingin dari 500 sampai 1500 kg/s.
