Alloy clear for use in high-temperature reactors

Alloy 617 - a combination of nickel, chromium, cobalt and molybdenum - has been approved by the American Society of Mechanical Engineers (ASME) for inclusion in its Boiler and Pressure Vessel Code. This means the alloy, which was developed by Idaho National Laboratory, can be used in proposed molten salt, high-temperature, gas-cooled or sodium reactors. It is the first new material to be added to the Code in 30 years.
