“…The volume fractions of each phase are calculated by the phase transformation model described in Section 8.13.6. As the overstress criterion may lead to unsafe predictions in low-stress situations [82], the combined criterion (3) is recommended.…”

“…The model consists of an overstress criterion, which establishes that cladding failure occurs when the local hoop stress exceeds a limiting burst stress. This concept is analogous to overstres criteria used for burst failure of Zircaloy under loss-of-coolant conditions [24,25]. The burst stress varies as a function of temperature and is derived from the failure behavior measured in recent out-of-pile FeCrAl cladding burst tests completed at ORNL by Massey et al [15].…”

This report contains the information necessary to set up fuel performance code calculations for the FeCrAl modeling benchmark in the IAEA ACTOF project. First, we provide a set of models and properties for a selected FeCrAl alloy. Detailed equations and data are given which can be implemented by participants in their codes. Second, we provide standard specifications for the benchmark cases. Proposed cases are relatively simple and cover both LWR normal operating and loss of coolant conditions. Details are given for geometries, input parameters and boundary conditions. To the benefit of the participants, indications on the setup of simulations based on previous experience at INL with the BISON code are also shared. Third, we provide lists of output parameters for code-to-code benchmark comparisons. Relative to previous publications and communications, additional information, data and discussion were added in this report, and corrections were made.

This report summarizes the contribution of Idaho National laboratory (INL) to the IAEA Coordinated Research Project on Fuel Modeling under Accident Conditions FUMAC. In line with the original research agreement bewtween INL/US DOE/Battelle and IAEA, work at INL has focused on both (i) developments of INL's fuel performance code BISON for the analysis of loss-of-coolant accidents (LOCA) and (ii) simulation of selected FUMAC priority cases. With reference to code development efforts, models were implemented in BISON for high temperature cladding oxidation, Zircaloy solid-solid phase transformation, Zircaloy high temperature creep, cladding burst failure and axial fuel relocation. BISON, analyses were performed of the FUMAC cases (1) MTA-EK tests PUZRY, (2) QUENCH L1 rods 4 and 7, (3) Halden IFA-650.2 and ( 4) Halden IFA-650.10. In addition, the REBEKA separate effects tests were analyzed, including an effort to investigate 3D cladding response in presence of azimuthal temperature variations. In general, BISON predictions of burst temperature, pressure and time to burst are very reasonable. Predictions of cladding hoop strain are less satisfactory and require additional investigation. Finally, results of 3D simulations indicated that 3D effects are potentially important in fuel rod analysis during LOCAs. BISON results are made available to the FUMAC project as a contribution to the FUMAC benchmark exercise.
