How to make metal alloys that stand up to hydrogen

High-tech metal alloys are widely used in important materials such as the cladding that protects the fuel inside a nuclear reactor. But even the best alloys degrade over time. Now, researchers has found a way of greatly reducing the damaging effects these metals suffer from exposure to hydrogen.
