The absorption of hydrogen in zirconium alloys and the potential precipitation of brittle hydrides is a key life controlling phenomenon for these alloys when used in nuclear reactors. This project represents a new collaboration between leading centres for academic research into the mechanical properties of zirconium in three countries (Canada, USA and Argentina). This research will provide an improved understanding of the influence of hydrides on crack propagation in these alloys. Longer term impacts of this research will have potential use on both nuclear power and hydrogen storage applications.

锆合金对氢的吸附和脆性氢化物的潜在析出是锆合金应用于核反应堆时的关键寿命控制现象。该项目代表了三个国家（加拿大、美国和阿根廷）锆机械性能学术研究中心之间的新合作。本研究将有助于进一步了解氢化物对这些合金裂纹扩展的影响。这项研究的长期影响将在核电和储氢应用方面具有潜在的用途。
