In 1967, C. Cawthorne and E. J. Fulton reported electron-microscope thin-foil examinations of type316 stainless-steel fuel cladding and mechanical-test specimens irradiated in the Dounreay Fast Reactor. The work helped identify microscopic cavities in the dimensional-instability problem.[ref]

C. Cawthorne coauthored Voids in irradiated stainless steel by C. Cawthorne and E. J. Fulton, reporting microscopic cavities in irradiated stainless steel. A related coauthored study, High-temperature Embrittlement of Stainless Steel irradiated in Fast Fluxes by A. S. Fraser and others, examines loss of high-temperature ductility. Together these contributions connect observations of irradiation damage to distinct dimensional and mechanical changes.[ref][ref]
