DoE on Verifiable Dismantlement of Nuclear Warheads
In anticipation of future nuclear arms control agreements that would require the dismantlement of nuclear warheads, the Department of Energy undertook a technical study during the Clinton Administration to determine how such dismantlement could be verifiably accomplished. The resulting report, experts say, is still the best available treatment of the subject.
A copy of the unclassified report, marked “official use only,” was obtained by Secrecy News and posted online today.
The DOE authors identified ten types of activities that could be used in a warhead dismantlement regime, involving various forms of monitoring at successive stages of the process. One or more of the ten could be employed, depending on the degree of confidence desired.
In principle, it should be fairly straightforward to dismantle a given nuclear warhead with confidence. However, “determining that an item to be dismantled is actually a nuclear warhead is very difficult” without compromising classified information, the report states. The use of x-rays or radiographs to confirm that an object is in fact a warhead “would be highly intrusive and would reveal highly classified nuclear warhead design information” to foreign inspectors, potentially exposing design vulnerabilities and other sensitive information. Such concerns might be addressed by other forms of monitoring, the report says.
The study concluded that “transparency measures for monitoring warhead dismantlement can be applied… with up to a moderate level of confidence that dismantlement has taken place if implemented at the Unclassified to [Confidential] level.” Verification that an actual weapon has been dismantled — which is a more demanding standard than mere “transparency” — can be achieved with an appropriate exchange of classified nuclear weapons design information.
The report provides a detailed description of the dismantlement process, a summary of previous dismantlement studies (including one by the Federation of American Scientists and another by the JASONs, but not the 1960s-era Project Cloud Gap study), and other valuable information that could serve to inform and accelerate current analyses of nuclear warhead dismantlement.

It is in the interests of the United States to appropriately protect information that needs to be protected while maintaining our participation in new discoveries to maintain our competitive advantage.
The question is not whether the capital exists (it does!), nor whether energy solutions are available (they are!), but whether we can align energy finance quickly enough to channel the right types of capital where and when it’s needed most.
Our analysis of federal AI governance across administrations shows that divergent compliance procedures and uneven institutional capacity challenge the government’s ability to deploy AI in ways that uphold public trust.
From California to New Jersey, wildfires are taking a toll—costing the United States up to $424 billion annually and displacing tens of thousands of people. Congress needs solutions.
