The United States intends to invest about $80 billion to maintain and modernize its nuclear weapons capabilities and infrastructure over the next decade. The National Nuclear Security Administration (NNSA), a semi-autonomous agency within the Department of Energy (DOE), maintains the nation's nuclear weapons through its Stockpile Stewardship Program (SSP). NNSA uses contractors to manage and operate eight separate sites, referred to as the nuclear security enterprise, to achieve the SSP's mission. The National Defense Authorization Act for Fiscal Year 2010 directed GAO to review the SSP. This report focuses on the extent to which NNSA has the data necessary to make informed, enterprisewide decisions, particularly data on the condition of infrastructure, capital improvement projects, shared use of facilities, and critical human capital skills. GAO analyzed agency infrastructure data; reviewed agency directives and guidance; and interviewed DOE, NNSA, and contractor officials. GAO recommends that NNSA take four actions to ensure that it is equipped with the information needed to effectively and efficiently manage the SSP. NNSA stated that it understood and can implement GAO's recommendations.

Work Description
The National Nuclear Security Administration's (NNSA) Tritium Readiness Program aims to establish an assured domestic source of tritium, a key isotope used in nuclear weapons, in order to maintain the U.S. nuclear weapons stockpile. Because tritium decays at a rate of 5.5 percent annually, it must be periodically replenished in the stockpile. However, since 2003, NNSA's efforts to produce tritium have been hampered by technical challenges. In this context, GAO was asked to (1) determine the extent to which NNSA has been able to overcome technical challenges producing tritium, (2) determine the extent to which NNSA is able to meet current and future nuclear weapons stockpile requirements for tritium, and (3) assess the management of NNSA's Tritium Readiness Program. To do this, GAO visited facilities involved in tritium production and reviewed tritium requirements established by NNSA and the Department of Defense, among other things. GAO recommends that NNSA develop a plan to manage tritium releases from reactors, analyze alternatives to its current tritium production strategy, ensure its contracting complies with appropriate contracting procedures, and ensure its future budget requests account for the program's large unexpended balances. NNSA generally agreed with our recommendations.
