Summary:

This publication by the International Atomic Energy Agency provides a comprehensive overview of the post-irradiation examination (PIE) techniques used to assess research reactor fuels. The text details various methods, both destructive and non-destructive, employed to evaluate the in-pile behavior and operational performance of nuclear reactor fuels. The guide is intended to assist fuel designers, fabricators, reactor operators, and regulators by offering insights into the irradiation performance and safety of research reactor fuels. It serves as a valuable resource for advancing the understanding of nuclear materials and supports the development and testing of new fuel systems. The publication is part of the IAEA Nuclear Energy Series, aiming to promote the peaceful use of nuclear technology. Generated by AI.
