FRACTURE TOUGHNESS IN NUCLEAR WASTE GLASSES AND CERAMICS - ENVIRONMENTAL AND RADIATION EFFECTS
The effects of atmospheric moisture and radiation damage on fracture properties of nuclear waste glasses and ceramics was investigated by indentation techniques. In nuclear waste glasses, atmospheric moisture had no measurable effect on hardness but decreased the fracture toughness. In nuclear waste ceramics, self-radiation damage from alpha decay decreased the hardness and elastic modulus; the fracture toughness increased with dose to a broad maximum and then decreased slightly with further increases in dose.
