Last month, the National Nuclear Security Administration hosted representatives from 11 members of the States Parties to the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) and one representative from the United Nations Office for Disarmament Affairs, who visited facilities in Los Alamos.
The officials from non-nuclear-weapon states visited not only Los Alamos National Laboratory facilities, but also Sandia National Laboratories facilities related to U.S. implementation of the NPT.
The NNSA laboratories gave an overview of the multidisciplinary work involved in maintaining a smaller stockpile of nuclear weapons in a non-explosive testing environment through science-based stewardship. They also showed activities that increase confidence in the safety, security, and effectiveness of the U.S. nuclear stockpile and ultimately allow for future reductions.
The party visited facilities and observed R&D demonstrations illustrating U.S. efforts to meet future nuclear arms control monitoring and verification requirements.
These activities highlighted laboratory capabilities supporting a wide variety of other national and international security goals, including nonproliferation and nuclear security.
The two-day visit and discussion of laboratory capabilities are among a number of U.S. transparency measures stemming from the 2010 NPT Review Conference Action Plan that encourages NPT states to enhance transparency and build mutual confidence.
The visit was led by Ambassador Adam Scheinman, U.S. Special Representative of the President for Nuclear Nonproliferation, and Dr. Don Cook, Deputy Administrator for Defense Programs.
