Corrosion of the AlFeNi alloy used for the fuel cladding in the Jules Horowitz research reactor

Annealing tests of in-pile irradiated oxide coated U–Mo/Al–Si dispersed nuclear fuel

“…8 g/cc U). It has been compacted and further enclosed by an AG3NE frame and an AlFeNi cladding [23]; the composition of these Al-Mg and Al-Fe-Ni-Mg alloys) are given in [24,25]. This assembly has been hot-rolled [26].…”

“…Note that Al self-diffusion has been found to be much quicker at temperatures close to Al melting point than Fe diffusion in Al [44] (no data have been found regarding Mg diffusion into Al). To fully validate this interpretation, Ni location should be characterised in this sample: its diffusion coefficient in Al is supposed to be much higher than Fe [44] and both elements are present in the cladding material with comparable weight fractions [25].…”

Quantitative crystallographic analysis of as-fabricated full size U–Mo/Al(Si) nuclear fuel plates

“…The material used for the frame is AG3NE [18] whereas the alloys for the cladding are either AG3NE or AlFeNi [19].…”

Effects of pH, surface finish and thermal treatment on the corrosion of AlFeNi aluminum alloy. Characterization of oxide layers

“…Many factors can increase the solubility of the aluminum oxide in water and further decrease its passivating role. Several corrosion studies developed in dynamic conditions on aluminum alloys used in research reactors dealt with the effect of the pH of the solution on the oxide growth rate [2][3][4][5][6][7][8]. Only a few studies were reported on the effect of surface finish and thermal treatment [1,9].…”
