20 Years of Success: Science, Technology, and the Nuclear Weapons Stockpile

On Oct. 22, 2015, NNSA celebrated the proven success of the Stockpile Stewardship Program at a half-day public event featuring remarks by Secretary of Energy Ernest Moniz, Secretary of State John Kerry, and Under Secretary for Nuclear Security and NNSA Administrator Lt. Gen. (retired) Frank G. Klotz. The event also featured remarks by Deputy Secretary of Energy Elizabeth Sherwood-Randall and NNSA Principal Deputy Administrator Madelyn Creedon.

W76-1 Life Extension Program (Maintaining the Stockpile)

The W76-1 is a refurbished W76-0 warhead, which is a submarine-launched ballistic missile system that was first introduced into the stockpile for the Navy in 1978. The W76-1 Life Extension Program extends the originally designed warhead service life of 20 years to 60 years. The W76-1 continues to meet all missions and capabilities of the original W76-0 warhead and does not provide new military capabilities. NNSA completed refurbished warhead production at the Pantex Plant in December 2018.

W88 Alteration 370 (Maintaining the Stockpile)

The W88 nuclear warhead entered the stockpile in late 1988 and is deployed on the Navy’s Trident II D5 Submarine-Launched Ballistic Missile (SLBM) system, carried onboard Ohio-class ballistic missile submarines. Deployed now for almost three decades, several updates are required to address aging issues and to maintain its current state of readiness. The W88 Alteration (Alt) 370 program replaces the arming, fuzing, and firing subsystem, adds a lightning arrestor connector, and refreshes the conventional high explosives within the weapon to enhance nuclear safety and support future life extension program options. The W88 Alt 370 program is scheduled to be completed concurrent with planned exchanges of limited-life, or routinely replaced, components, including the gas-transfer system

Article on Trident Laser Facility for NA-11 Stockpile Stewardship Quarterly

The Trident Intermediate-Scale Laser Facility at Los Alamos National Laboratory is an extremely versatile Nd:glass laser system dedicated to high energy density laboratory physics and weapons physics research and fundamental laser-matter interactions. Trident is a three-beam, 200 J/beam at the second harmonic for glass (527 nm wavelength), facility with tremendous flexibility and high beam quality. Pulse durations varying over 6 orders of magnitude, from 0.5 picoseconds to 1.0 microsecs, can be directed to either of two different target chambers with changeable illumination geometries, including the ability to achieve near-diffraction limited focus. This provides a unique range of capability at one facility from sub-picosecond pulses (and high-intensity laser science) to nanosecond pulses (and LPI physics relevant to ICF) to microsecond pulses (and driving flyer plates for supported shock dynamic materials science.) When in short-pulse mode (less than picosecond pulse), a single beam can provide up to 200 TW of power with uniquely controllable and measured pre-pulse contrast of 10 orders of magnitude. A recent external capability review at Los Alamos concluded that "Trident is generating excellent, cutting edge science and is a leading intermediate scale laser system worldwide."

Los Alamos Explosives Performance Key to Stockpile Stewardship

As the U.S. Nuclear Deterrent ages, one essential factor in making sure that the weapons will continue to perform as designed is understanding the fundamental properties of the high explosives that are part of a nuclear weapons system. As nuclear weapons go through life extension programs, some changes may be advantageous, particularly through the addition of what are known as "insensitive" high explosives that are much less likely to accidentally detonate than the already very safe "conventional" high explosives that are used in most weapons. At Los Alamos National Laboratory explosives research includes a wide variety of both large- and small-scale experiments that include small contained detonations, gas and powder gun firings, larger outdoor detonations, large-scale hydrodynamic tests, and at the Nevada Nuclear Security Site, underground sub-critical experiments.
