Abstract


Bahan struktur merupakan salah satu kunci penting dalam penelitian reaktor nuklir generasi keempat. Sejak peristiwa kecelakaan di pembangkit listrik tenaga nuklir Fukushima–Daiichi, telah terjadi peningkatan pengembangan Accident Tolerant Fuel (ATF) Cladding atau kelongsong bahan bakar toleran kecelakaan untuk menghindari kecelakaan reaktor air ringan. Maka dari itu Inovasi perekayasaan ATF merupakan salah satu kegiatan dalam litbang material maju yang sedang banyak dikembangkan. Kandidat material yang paling menjanjikan untuk ATF cladding adalah Baja yang diperkuat dengan dispersi oksida (ODS). Dalam penelitian ini baja ODS feritik Fe-Cr-Al-W-Ti-Zr-Y2O3 disintesis dengan metode mekanosintesis menggunakan alat planetary ball mill (PBM) dengan variasi komposisi Zr sebesar 0%, 0.5%, 1%, dan 1.5%. Mekanosintesis dilakukan selama 8 jam dengan menggunakan bola stainless steel. Perbandingan berat antara sampel dengan bola adalah 1:10. Kemudian dilakukan karakterisasi menggunakan mikroskop optik, XRD, dan SEM-EDS. Hasil observasi menunjukkan homogenitas yang baik pada bahan hasil sintesis.
