New Material Finally Makes It Into the Almighty Nuclear Code

Posted by in categories: materials, nuclear energy

Scientists working at Idaho National Laboratory (INL) have announced the approval of a new high-temperature metal after 12 years and a $15 million Department of Energy investment. Alloy 617, a “combination of nickel, chromium, cobalt and molybdenum,” is tolerant and strong at temperatures of more than 1,700 degrees Fahrenheit. The scientists say this means it could be used in existing high temperature nuclear facilities as well as cutting-edge applications like molten salt reactors.

For any new nuclear plant material, making the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code is like qualifying for the Olympics. Alloy 617 is the first new material to get into “The Code” in 30 years.
