Our mission is to develop and deploy advanced technologies for safer, reliable, sustainable, clean energy.

Our Goals

The Center for Advanced Small Modular and Microreactors (CASMR) will develop and prove technologies that deliver affordable, reliable, resilient, secure, flexible and sustainable energy. We strive for unparalleled safety and zero-carbon emission clean energy.

The center aims to hasten the development of new and transformative technologies, materials and methods to make nuclear fission more affordable. We will work to deploy nuclear fission rapidly and securely. 

CASMR will develop the best, brightest ideas in research to build a community of innovators. These innovators will work together to create practical solutions to advance many industrial sectors, including space, manufacturing, emergency response and defense.

The Center for Advanced Small Modular and Microreactors is a Texas A&M Engineering Experiment Station (TEES) center. We are well-positioned to conduct research that furthers advanced nuclear reactors’ design, construction and operation. 

Building upon TEES’ vast innovation capabilities, the CASMR supports work across the technology development spectrum. The spectrum ranges from basic materials research to reactor design, manufacturing and deployment. 

We join a diverse group of domestic and international industry and government organizations and laboratories to collaborate on nuclear energy initiatives. Thus, our research aligns with the most pressing needs for decarbonizing the power sector and the broader energy system. 

By encouraging industry engagement, the center serves as an integrated solutions platform. We will enable applied research with an awareness of the practical and market barriers that must be tackled to move technologies from lab to market.

The CASMR will pursue and support new approaches for multidisciplinary nuclear research and development, education and external partnerships. 

Our approaches cross departmental and college boundaries. They address all facets of the energy landscape that connect engineering, sciences, technologies, economics, law and policy decisions. 

The center’s interdisciplinary research program will focus on the nuclear energy of small modular reactors and microreactor technologies important to industry, national laboratories, the Department of Defense and the National Aeronautics and Space Administration. 

Our engagement with energy end-users will lead to solutions for the use of nuclear-generated energy (heat) from small modular reactors and microreactors. These solutions will meet energy needs for the hydrogen economy, water desalination by nuclear power, and chemical heat processes..

Small modular and micro reactors consist of related technologies and applications of nuclear science, industrial processes, education and training, energy systems, space exploration, and defense.
