Apr 9, 2024In this work, material models and correlations for Cr-coatedZircaloycladding have been derived or obtained from the literature and implemented into TRANSURANUS and FRAPTRAN-TUmech. These extended tools have been used to simulate two LOCA tests, enabling a cross-verification of results between codes and a comparative performance analysis ...

Demonstrating the improved response of Cr-coatedZircaloy requires the development or extension of fuelperformance codes to coating simulations. In this work, material models and correlations for Cr-coatedZircaloycladding have been derived or obtained from the literature and implemented into TRANSURANUS and the FRAPTRAN-TUmech suite.

Chromium coatings are being developed for advanced technology fuel (ATF) claddings, offering negligible corrosion during normal operation, improved resistance to high-temperature steam oxidation, and superior high ...
Jun 1, 2024Deformation and failure of chromium (Cr) coated Zircaloy-4 (Zry-4) were studied in loss-of-coolant accident (LOCA) conditions using the BISON fuelperformance code. The BISON validation model simulating Halden research reactor experiments was extended to include Cr coatings and higher rod internal pressures to simulate high-burnup fuel.

(DBAs) or beyond-DBA by an application of Cr-coating, the degree of chromium diffusion and its impact on cladding ductility should be accounted for. In such a context, this study aims at developing and validating a mechanistic Zr-Cr binary diffusion model for Cr-coated Zr-Nb alloy cladding. The model solves
