Maintaining the U.S. Nuclear Stockpile in the Absence of Nuclear Explosive Testing
Fact Sheet
Bureau of Arms Control, Verification and Compliance
September 26, 2012
The leading methods used to maintain the United States nuclear weapons stockpile include:
Life Extension Programs (LEPs) extend the service life of the current weapons in the stockpile by using only nuclear components based on previously tested designs thereby eliminating the need to conduct nuclear explosive tests. NNSA, in coordination with the Department of Defense (DoD), also performs alterations and modifications to the stockpile in order to sustain the warheads that underpin the U.S. nuclear deterrent.
Advanced Simulation and Computing capabilities provide greatly increased confidence in the ability to model and evaluate the performance and safety of nuclear weapons without nuclear explosive testing. Computers have become at least a hundred-thousand times more powerful, and modern integrated design codes now more realistically capture the behavior of real nuclear devices.
Enhanced Surveillance tools and models play critical roles in providing information essential to assessing weapon safety, security, and performance changes that would affect military effectiveness. The use of data from surveillance of our nuclear weapons enables us to predict how the weapons will perform over time without using underground nuclear explosive testing.
The Annual Assessment process of the U.S. Nuclear Weapons Stockpile is the authoritative method for the DoD and NNSA to evaluate the safety, reliability, performance and military effectiveness of the nuclear weapons stockpile, and it is a principal factor in our ability to maintain a credible nuclear deterrent without nuclear explosive testing.
Infrastructure Modernization is in accordance with the Nuclear Posture Review; NNSA has identified a path for sustaining the nuclear deterrent while modernizing the supporting infrastructure without nuclear explosive testing. This modernization is implemented by focusing on recapitalization and refurbishment of existing infrastructure for plutonium, uranium, tritium, high-explosive production, non-nuclear component production, high-fidelity testing and waste disposition
