“…However, oxidation affects the burst behavior of the Zr-based alloy cladding in a manner more complex than simple metal thickness loss. Oxygen diffuses across the oxide layer into the cladding [23] where it exhibits a very high solubility in α-Zr [24] and therefore affects the phase transformation kinetics [25] and the mechanical properties of the cladding. A number of state-ofthe-art reviews of cladding burst behavior [26][27][28] and models [29] are available.…”

Burst behavior of austenitic and ferritic Fe-based alloy tubes has been examined under a simulated large break loss of coolant accident. Specifically, type 304 stainless steel (304SS) and oxidation resistant FeCrAl tubes were studied alongside Zircaloy-2 and Zircaloy-4 that are considered reference fuel cladding materials. Following the burst test, characterization of the cladding materials was carried out to gain insights regarding the integral burst behavior. Given the widespread availability of a comprehensive set of thermo-mechanical data at elevated temperatures for 304SS, a modeling framework was implemented to simulate the various processes that affect burst behavior in this Febased alloy. The most important conclusion is that cladding ballooning due to creep is negligible for Fe-based alloys. Thus, unlike Zr-based alloys, cladding cross-sectional area remains largely unchanged up to the point of burst. Therefore, for a given rod internal pressure, the temperature onset of burst in Fe-based alloys appears to be simply a function of the alloy's ultimate tensile strength, particularly at high rod internal pressures.

“…Ekinox-Zr is a numerical tool able to simulate the oxidation of zirconium alloys at high temperature [4], [5], [8]. In this model, the cladding tube is represented as a one-dimensional domain containing the successive layers: ZrO2, Zr(O) and Zr .…”

“…It has been demonstrated that the ductility of this quenched Zr phase depends upon the O content: for oxygen contents superior to 0.4wt.%, this phase becomes brittle [3]. A tool has been developed, Ekinox-Zr [4]- [7], able to calculate the O concentration profiles in the three successive layers, ZrO2, Zr and Zr, and the growth of these layers as a function of time at a given temperature [8]. This tool, linked to the Zircobase database and the Thermo-Calc software, has already demonstrated its ability to forecast high temperature isothermal oxidation of Zr alloys [4]- [7].…”

Thermodynamic and kinetic calculations are commonly used for forecasting phase transformations in multi-component alloys as a function of composition, temperature and time. They also turn to be very useful for new alloys design. Thus, in the framework of the qualification of existing industrial alloys and the development of new ones (Cr coated Zr alloys for instance), a new generation of thermodynamic database has been developed thanks to the systematic use of ab initio calculations. Indeed, DFT (Density Functional Theory) calculations are significant for the determination of formation enthalpies of stable and metastable phases. Moreover, SQS method (Special Quasirandom Structure) is used for the prediction of fcc, bcc and hcp mixing enthalpies in binary solid solutions.

Corvalán-Moya [17] investigated a model that can accurately predict the ''critical'' oxidation time corresponding to the overall ductile-to-brittle transition of a high-temperature (HT) oxidized clad. Sridharan [18] examined the oxidation behavior of a plasma surface modified zirconium alloy in pressurized high-temperature water.…”
