title: Ceramic nuclear fuel mechanical resistance development by means of dynamic impact testing.
abstract: In commercial reactors where a 'pellet missing surface' is observed a cladding crack has also been observed several times. Chips are produced mainly by dynamic impacts during pellet production process as a whole, i.e. emptying the sintering boats, pellets handling, vibration in the bowl feeder and grinding. At this work UO(2) chipping behavior was investigated and showed that pellets with higher density resist more to impacts and also that at the lowest impact angle tested the pellet weight loss was quite high.
