Fuel Pellets | Definition & Characteristics | nuclear-power
Fuel Pellets. In nuclear reactors, fuel pellets are ceramic cylinders made from UO 2. These cylindrical pellets are loaded and encapsulated within a fuel rod (or fuel pin), made of zirconium alloys due to their very low absorption cross-section (unlike stainless steel). The surface of the tube, which covers the pellets, is called fuel cladding.
Densification mechanisms of UO2 consolidated by spark plasma sintering
Spark plasma sintering (SPS) is a field assisted sintering technique (FAST) that allows densification to occur at lower temperatures and with shorter processing times, when compared with conventional sintering (CS) and hot pressing (HP). The main difference with the latter is the use of a pulsating current through the die sample assembly.
