Description

CANDU reactors each contain several hundred zirconium-niobium pressure tubes. The zirconium-niobium alloy is prone to hydrogen (and deuterium) absorption, which can lead to the formation of brittle zirconium hydride platelets within the metal. These hydrides have caused a number of pressure tube leaks, and were the cause of a major failure in one early reactor. They have necessitated the retubing (or the scheduled retubing) of the earliest reactors at a cost of several hundred million dollars each.
