ABSTRACT
An empirical
model predicting the oxide film thickness on aluminum alloy cladding during
irradiation has been developed as a function of irradiation time, temperature,
heat flux, pH, and coolant flow rate. The existing models in the literature are
neither consistent among themselves nor fit the measured data very well. They
also lack versatility for various reactor situations such as a pH other than 5,
high coolant flow rates, and fuel life longer than ~1200 hrs. Particularly,
they were not intended for use in irradiation situations. The newly developed
model is applicable to these in-reactor situations as well as ex-reactor tests,
and has a more accurate prediction capability. The new model demonstrated with
consistent predictions to the measured data of UMUS and SIMONE fuel tests
performed in the HFR, Petten, tests results from the ORR, and IRIS tests from
the OSIRIS and to the data from the out-of-pile tests available in the
literature as well.
