The Study of Manufacturing and Ingot Characterization of U-Zr Alloys

Abstract: Manufacturing and characterization of U-Zr alloys for PWR fuel types have been conducted. At first U-Zr alloy ingot was made by melting U and Zr metal in the electric arc furnace that is equipped with a water cooler and in an atmosphere of argon gas. Ingot manufacturing of U-Zr alloy was done at Zr concentration 35%, 45%, 55% and 65% weight respectively. U-Zr ingot result was cut for testing, such as: density, hardness, microstructure and phases. Density testing was done by using Autopicnometer, hardness by us… Show more

“…As the temperature increases even higher, the precipitation remains in the stable bcc band-like structure, but the separated uranium begins to change from bcc to a more liquid state. The band-like atomistic configuration shows the thermodynamic driving force to the lamellar [1][2][3] and acicular [5,7,8,46,47,50,51] microstructures observed experimentally and shown in Fig. 1a and Fig.…”

“…Pengembangan bahan bakar PWR baik UO2 maupun jenis yang lain dilakukan untuk meningkatkan unjuk kerja melalui peningkatan burn up (derajat bakar) karena dengan meningkatnya burn up maka akan menurunkan kebutuhan bahan bakar baru per energi yang dihasilkan [1] . Penggunaan bahan bakar paduan U-Zr telah lama digunakan secara luas, seperti untuk bahan bakar reaktor TRIGA (Training Isotop by General Atommic) dalam bentuk U-ZrHx, Advance Boiling Water Reactor (ABWR), FBR (Fast Bredeer Reaktor) dan EBR (Experiment Breeder Reactor) yang mana dibuat dalam bentuk campuran antara U, Pu dan Zr [2,3] .…”

“…Oleh karena pada pengukuran dengan auto pycnometer yang mempunyai volume lebih kecil dan apabila digunakan untuk membagi berat sampel yang sama maka akan menghasilkan nilai densitas yang lebih besar. Hasil tersebut bila dibandingkan dengan hasil pengukuran densitas pada pembuatan pelet sebelum disinter (green pellet) yang pernah dilakukan di Pusat Teknologi Bahan Bakar Nuklir dengan hasil yang tidak berbeda, yakni untuk pelet yang diukur secara manual diperoleh nilai densitas sebesar 6,7052 g/cm 3 sedangkan dengan menggunakan auto pycnometer diperoleh nilai densitas sebesar 10,43 g/cm 3 [2] . Gambar 3.…”
