Description
Coated fuel particles in capsules will be irradiated at about 16000C in JMTR. Nb-1%Zr alloy was chosen for inner shell material of the capsules because of its sufficient strength at 10000C and low induced radioactivity. Nb-1%Zr ingot produced by electron beam melting was formed into seamless tubes by hollowing and swaging, followed by annealing. Creep test in helium flow and tensile test in vacuum were made to examine mechanical strength of the Nb-1%Zr tubes at 10000C. Following are the results; 1) 0.2% yield stress at 10000C is about 6 kg/mm2. 2) 3000 hr creep rupture stress at 10000C is about 6 kg/mm2. (auth.)
