From the 1960s to the end of the 20th century, considerable studies were performed in Europe on fast breeder reactor fuels for reaching an industrial maturity. In the European plan, the European fast reactor project reached in 1998 the phase of validation of the concept, satisfying the requirements of economy and safety of the countries that contributed to the project.
In this paper, we intend to give an idea about the main obstacles met on the way toward the high burnups: inner corrosion cladding interface, swelling and mechanical behavior of the constitutive materials (clad and wrapper), pin/pin interactions and pin/wrapper mechanical interactions, wrapper interactions within the reactor core, etc.
For this, the paper is divided in three parts:
