The Questions of Compliance With the NPT Regime and Complex Multilateral Nuclear Negotiations: A Comparative Analysis of North Korea and Iran As Defector States
… of Hiroshima and Nagasaki in August 1945, nuclear weapons have never been used in a war despite the conditions of international relations characterized by constant conflict and instability. The norm of nuclear nonproliferation institutionalized by the NPT has been the major force behind …

Maintaining Nuclear Stability in the Wake of a Strained Liberal Order
… that allowed the current order to blossom. The nuclear nonproliferation regime coevolved with the liberal order, and as the order moves away from American hegemony, the nonproliferation regime, as an institution of the liberal order, is also evolving. Unlike other institutions that may decline …

Epistemic Communities and Proliferation: The Implications of Nuclear Knowledge
<p>How do epistemic communities facilitate nuclear proliferation? The nuclear nonproliferation regime contains numerous actors exerting varying levels of influence on policy outcomes and state behavior. Neoliberal institutional theory emphasizes the role of sub-national groups play in forming …

Technical basis for use of a correlated neutron source in the uranium neutron coincidence collar
Nuclear nonproliferation efforts rely on a variety of safeguards to protect sensitive materials in nuclear facilities. The enrichment of fresh light-water-reactor fuel assemblies is verified by several inspectorates using the uranium neutron coincidence collar (UNCL), which uses neutrons from an …

A 3D Computational Fluid Dynamics Model Validation for Candidate Molybdenum-99 Target Geometry
As part of its nuclear nonproliferation mission, the U.S. Department of Energys Global Threat Reduction Initiative (GTRI) is working to develop a sustainable means for producing the critical medical isotope molybdenum-99 (99Mo) without using highly enriched uranium (HEU). 99Mo is the parent product …

Gold Standard or Case-by-Case: Which Method Is Best for the Nonproliferation Regime?
With the Manhattan Project in the 1940s, U.S. nuclear technology created the first nuclear bombs, which promptly ended World War II. What to do with this new technology with regard to nuclear armaments never seemed hard to comprehend, as the world witnessed the advent of the nuclear arms race that …
