Phase transformations in Cr-coated zirconium nuclear fuel cladding studied by in-situ neutron diffraction
Cr-coating of the classical Zr-based claddings is a new concept supposed to bring more safety in case of an accident in a nuclear power plant. It is important to study the phase transformations occurring in such alloys during the temperature transients encountered in accidental conditions. Model alloys have been synthesized aiming to reproduce the different levels of chromium reached in the cladding after an accidental excursion at high temperature. Studying these model alloys allow to reproduce the phase transformations occurring in the complete cladding. In-situ neutron diffraction allows to study not only the phase transformation occurring as a function of temperature but also the partitioning of the different elements via the measurement of lattice parameters. We will study two model samples plus the complete cladding in-situ. In addition, ex situ measurements will be performed on samples previously quenched with a quenching rate not obtainable in in-situ conditions.
