Swelling incubation 2026-10-20
The transient dose interval before substantial measurable cavity void swelling. Nucleation and evolution of competing defect sinks make it sensitive to starting microstructure and irradiation conditions.
Swelling rate per displacement dose 2026-10-20
The derivative of volume void swelling with respect to displacement dose, . It differs from a time rate; conversion requires a dose rate and a specified irradiation history.
Journal of Nuclear Materials 367–370, pp.954–959. The official laboratory abstract describes pressurized-tube measurements separating irradiation creep, void swelling, precipitation and plastic strain. The source's full title continues “Irradiated as Pressurized Tubes in the EBR-II Fast Reactor”.
