Los Alamos National Laboratory

For nearly a decade, the Laboratory, in partnership with its sister Defense Programs laboratories and the Department of Energy (DOE)/National Nuclear Security Administration (NNSA), has maintained the enduring nuclear stockpile without nuclear testing. National science-based Stockpile Stewardship is the program through which the safety, reliability, and performance of the United States nuclear stockpile is assured. Through Stockpile Stewardship and other programs, LANL develops and applies the best science and technology to meet national security requirements by creating and adapting capabilities to address critical mission needs.
