Abstract
Pellet-Cladding Interaction (PCI) in a Light Water Reactor is one of the major concerns to guarantee fuel rod clad integrity of PWR nuclear reactor during operations needed to follow power grid demand. In order to forbid operations leading to clad failure, modeling capability to simulate the mechanism has improved through the years. And, Codes need more and more detailed and precise experimental data. Until now, those data result from dedicated irradiation programs, named “power ramp tests”, carried out in experimental devices in Material Testing Reactors, ISABELLE in OSIRIS in the past and the future ADELINE in the Jules Horowitz Reactor JHR.
There is currently no instrumentation for online PCI detection required for full validation of the modeling scheme.
A previous work has shown that it is possible to measure, under specific conditions, the effects of PCI on the vibrations of a nuclear fuel rod subjected to axial excitation of turbulent flow under external conditions. The objective of this PhD thesis will then be to develop a general process, including the three aspects, modelling, measurement and data processing, in order to improve existing methods capable of providing precise information on the mechanical interactions of the components of a complex structure in a very constrained context (limited space for instrumentation, high temperatures, irradiation, etc.).
