Understanding the high-temperature corrosion behavior of zirconium alloy as cladding tubes: a review
Publikováno v:
Frontiers in Materials, Vol 11 (2024)
Operated under extreme conditions, corrosion occurs between zirconium alloy cladding tubes and the coolant in the primary loop of pressurized water reactors (PWRs), contributing to a reduction in the effective metallic material thickness. Therefore,
