The Nuclear and Radiochemistry (C-NR) Group provides vital radiochemical and radioanalytical capabilities to a wide range of programs. These programs include maintenance and stewardship of the nuclear stockpile, nuclear non-proliferation, environmental management, international safeguards, repository validation, and civilian nuclear energy programs.

We perform research and addresses immediate mission needs for sponsors in nuclear weapons, global security, and for those requiring the use of radioanalytical and radiochemical handling capabilities at a range of (radio) activity levels. Current major sponsors include the National Nuclear Security Administration, other federal agencies (Department of Defense, Department of Homeland Security, etc.), and LANL institutional support. Basic and applied research is conducted in support of radiochemistry and radioanalytical methods, nuclear chemistry and physics, and inorganic chemistry.
