After the Cold War, the U.S. voluntarily ended underground nuclear testing. NNSA maintains the existing nuclear deterrent through the use of science experiments, engineering audits and high-tech simulations at its three national laboratories: Los Alamos National Laboratory, Lawrence Livermore National Laboratory, and Sandia National Laboratories.
The Advanced Simulation and Computing Program (ASC) is a super-computing program run by the National Nuclear Security Administration, in order to simulate, test, and maintain the United States nuclear stockpile. [1] The program was created in 1995 in order to support the Stockpile Stewardship Program (or SSP). The goal of the initiative is to ...
NNSA officials believe the program is needed to maintain nuclear weapons expertise in order to rapidly adapt, repair, or modify existing weapons or develop new weapons as requirements evolve. They see the ability to adapt to changing military needs rather than maintain additional forces for unexpected contingencies as a key program driver. [ 9 ]
The new Sentinel nuclear weapons program is 81% over budget and is now estimated to cost nearly $141 billion, but the Pentagon is moving forward with the program, saying that given the threats ...
The Nuclear Emergency Support Team (NEST), formerly known as the Nuclear Emergency Search Team, is a team of scientists, technicians, and engineers operating under the United States Department of Energy's National Nuclear Security Administration (DOE/NNSA). NEST is the umbrella designation that encompasses all DOE/NNSA radiological and nuclear ...
Material Protection, Control and Accounting (MPC&A) refers to the safeguarding of nuclear assets, including nuclear fuel and weapons. In the United States, the National Nuclear Security Administration (NNSA), a component of the Department of Energy, oversees MPC&A as part of its non-proliferation program.
Iran may decide to build nuclear weapons following tit-for-tat strikes with arch-foe Israel and Biden's failure to revive major power talks with Iran on restoring curbs on its nuclear program.
A Safeguards Transporter (SGT) is a truck developed for and used by the National Nuclear Security Administration (NNSA), a semi-autonomous affiliate agency of the United States Department of Energy, for the ground transport of nuclear weapons in the contiguous United States. SGTs' trailers are known as Safe Secure Trailers (SST).
