Keywords:Fast Reactor, Annular fuel pin, Post irradiation examination, gamma scanning, Fuel pin diameter measurement, Ceramography, Cs migration behaviour, Fuel-Cladding mechanical interaction

Evaluation was made on irradiation behavior of annular fuels by using post irradiation examinations of MOX fuel pins irradiated in EBR-II, showing difference in FCMI and Cs migration behaviors between annular fuel pins and solid fuel ones.
