pellet

Ceramic fuel pellets also can be fabricated in an advanced process called sol-gel microsphere pelletization. The sol-gel route (described in the article advanced ceramics) achieves homogeneous distribution of uranium and plutonium in solid solution, enables sintering to occur at lower temperature, and ameliorates the toxic dust problem…

… (ICF) reactor, a tiny solid pellet of fuel—such as deuterium-tritium (D-T)—would be compressed to tremendous density and temperature so that fusion power is produced in the few nanoseconds before the pellet blows apart. The compression is accomplished by focusing an intense laser beam or a charged particle beam, referred to…

Finished pellets are round and have diameters of 10 to 15 millimetres, making them almost the ideal shape for the blast furnace.

Pellets made of low-enrichment UO₂ are universally employed as fuel in commercial light-water reactors that produce electrical energy. The pellets are made by blending appropriate quantities of enriched and natural or depleted UO₂ powders, mechanically compacting them, adding an organic binder, pressing into pellets, heating…
