Initial examination of fuel compacts and TRISO particles from the US AGR-2 irradiation test

•Compacts from the US AGR-2 irradiation test suspected of Cs release were examined.•Acid leaching and particle gamma scanning were used to investigate releases.•TRISO particles with SiC failure were isolated by gamma screening.•SiC failure was studied by X-ray tomography and SEM with elemental analy...
