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.
The Department of Energy's Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time.
