Nuclear Weapons: NNSA Plans to Modernize Critical Depleted Uranium Capabilities and Improve Program Management
Abstract
High-purity DU is an important strategic material for ongoing and planned modernizations of the nations nuclear weapons stockpile. However, according to NNSA estimates, NNSA has a very limited supply of DU feedstock, and its current supply of DU metal will be exhausted in the late 2020s. NNSA also does not have the full range of capabilities needed to manufacture DU into weapon components needed for modernizing the stockpile. GAO has previously reported that NNSA has experienced challenges in restarting some technical manufacturingprocesses. A Senate committee report accompanying a bill for the National Defense Authorization Act for Fiscal Year 2017 included a provision for GAO to examine NNSAs management of DU for nuclear stockpile modernization. GAOs report examines (1) the status of NNSAs efforts to obtain the necessary quantities of DU to meet stockpile modernization requirements; (2) the status of NNSA efforts to develop DU component manufacturing capabilities to meet stockpile modernization requirements; and (3) the extent to which NNSA is managing DU activities as a program, consistent with agency policy. GAO reviewed relevant agency documents; interviewed NNSA officials and contractor representatives; and conducted site visits at headquarters and at research, development, and production locations.
