The Y-12 National Security Complex in Oak Ridge, Tennessee, is one of six production facilities in the National Nuclear Security Administration's (NNSA's) Nuclear Security Enterprise (NSE). Y-12’s unique emphasis is the processing and storage of uranium and development of technologies associated with those activities. Decades of precision machining experience make Y-12 a production facility with capabilities unequaled nationwide.
Y-12 helps ensure a safe and effective U.S. nuclear weapons deterrent. We also retrieve and store nuclear materials, fuel the nation’s naval reactors, and perform complementary work for other government and private-sector entities.
Since 1943, Y-12 has played a key role in strengthening our country’s national security and reducing the global threat from weapons of mass destruction. Y-12 has evolved to become the complex the nation looks to for support in protecting America's future, developing innovative solutions in manufacturing technologies, prototyping, safeguards and security, technical computing and environmental stewardship.
In meeting the country’s evolving nuclear security needs, Y-12 has developed unique skills and acquired a wealth of experience that benefit the nation and world. Expertise in science-based product evaluation, materials science, precision manufacturing, applied manufacturing technology, nuclear nonproliferation, data-driven operations management, and the handling of nuclear materials has spurred scientific research and sparked innovation.
Consolidated Nuclear Security, LLC manages and operates the facility along with the Pantex Plant in Texas under a single contract from the U.S. Department of Energy/NNSA.
Ashley Stowe’s technical expertise in novel materials spans from energy storage to ionizing radiation detection. He has numerous publications in development of chemical and metal hydride systems as well as radiation detection materials for handheld and imaging applications. He also has expertise in materials compatibility and aging as well as instrument and method development for the characterization of associated chemistries. He was previously named a Y-12 Technical Fellow and Director of the Nuclear Forensics and Detection Initiative. In that role, he acted as a technical lead, coordinating technology transfer activities and leveraging university partnerships for radiation detection technologies. Stowe holds 15 patents, has authored more than 70 publications, and was recognized with a 2013 R&D 100 award for his pioneering development of the 6LiInSe2 semiconductor radiation detection crystal. He holds a Ph.D. in physical chemistry and an MBA. His research interests include materials development, spectroscopy and materials characterization, crystal growth, radiation detection, and high energy radiation imaging.
