Stockpile Stewardship

The Stockpile Stewardship Program was established in response to the Fiscal Year 1994 National Defense Authorization Act (Public Law 103-160), which requires, in the absence of nuclear testing, a program to:

  1. Support a focused, multifaceted program to increase the understanding of the enduring stockpile;
  2. Predict, detect, and evaluate potential problems of the aging of the stockpile;
  3. Refurbish and re-manufacture weapons and components, as required; and
  4. Maintain the science and engineering institutions needed to support the nation’s nuclear deterrent, now and in the future.

As the civilian steward of the nation’s nuclear weapons complex, the U.S. Department of Energy (DOE) National Nuclear Security Administration is responsible for the safety and reliability of the nation’s nuclear arsenal. The U.S. Department of Defense partners with the DOE in setting requirements and establishing production goals against civilian and military surety and safety concerns.

A suite of enhanced capabilities and facilities across the Nuclear Weapons Complex (which includes weapons laboratories, production plants, and the Nevada National Security Site) have been developed to fill in the knowledge gaps and to provide data relevant to identified stockpile concerns. Capabilities specific to the Nevada National Security Site include: Atlas, the Big Explosives Experimental Facility (BEEF), the Device Assembly Facility (DAF), the Joint Actinide Shock Physics Experimental Research (JASPER) Facility, and the U1a Complex.
