Solidification phenomena for UO2, UC, and UN relative to quenching in sodium coolant

Thermal stress initiated fracture as a fragmentation mechanism in the UO2-sodium fuel-coolant interaction

“…In contrast to the molten drop models, recent efforts to take into account the possibility of solidification of the hot material have resulted in solid shell theories of fragmentation (76)(77)(78)(79) (80) was used.…”

“…Before extending this type of model to the U0 2 -Na system, Cronenberg et al (78,79) for continuity.…”
