Multimetallic Layered Composites (MMLCs) for Rapid, Economical Advanced Reactor Deployment
Project Innovation + Advantages:
The Massachusetts Institute of Technology (MIT) will lead a team including Georgia Tech, Louisiana Tech, and the Idaho National Lab in developing multimetallic layered composites (MMLCs) for advanced nuclear reactors and assessing how they will improve reactor performance. Rather than seeking complex alloys that offer exceptional mechanical properties or corrosion resistance at unacceptable cost, this team will develop materials with functionally graded layers, each with a specific function. The team will seek general design principles and engineer specific MMLC embodiments. The materials developed will be tested using irradiation experiments, coupled with predictive models for performance under irradiation. To date, the issue of material performance at low cost has proved a challenge for advanced reactor deployment. Developing a scalable method of materials manufacturing and testing for advanced nuclear reactors could facilitate their rapid deployment, thereby reducing energy-related emissions and improving energy efficiency.
This project aims to develop MMLCs, engineered materials that offer the properties needed for demanding future nuclear reactor requirements. Through realizing MMLCs, a pathway toward advanced reactors may be enabled.
The technology will reestablish U.S. leadership in advanced metal composite development.
This solution will reduce energy-related emissions by enabling rapid, advanced nuclear reactor deployment and improve energy efficiency via the higher thermodynamic efficiency and closed fuel cycles of advanced nuclear reactors.
This work will reinvigorate U.S. steel and specialty metals industries by creating design principles for new engineered materials suitable for future advanced reactors and other demanding applications. In addition, it will explicitly test MMLC manufacture at commercial scale on domestic facilities to demonstrate a high technology readiness level.
