| 内容記述 | Neutron multipliers with lower swelling and higher stability at elevated temperatures are desired for the pebblebed blankets of designed DEMO rector. Among beryllium-based intermetallic alloys, vanadium beryllide Be12Visconsidered to be an attractive material from the point of view of its potential use as an advanced neutronmultiplier of the breeding blanket.Rotating electrode method (REM) was applied in this study for fabrication of sphere-shaped Be12V pebblesusing a plasma-sintered Be-V electrode. Be-V electrode as raw material played a role of the target which wasmelted and centrifugally ejected in the form of spherical droplets in the helium-filled atmosphere of REM ap-paratus. Since the angular rotation speed of Be-V rod is one of the important technological parameters whichsignificantly influences the sizes of produced pebbles, the wide operating range (2000–10000 rpm) was selectedby granulation process and produced batches of pebbles were analyzed. The yield properties, sizes and somecharacteristics of microstructure of fabricated vanadium beryllide pebbles are summarized and discussed in thiswork. Besides this, thefirst results on investigation of the packing density of single- and binary-sized pebble bedsconsisting of Be12V pebbles showed that the maximal achieved packing factor values are, accordingly, about64–65 and 80%. | |||||
