CEνNS in Natural Zinc Superconductors and its Applications for Nuclear Non-Proliferation
The potential of neutrinos for nuclear non-proliferation has been heavily debated due to their abundance and low interaction rates. A newly discovered neutrino detection technique, referred to as Coherent Elastic Neutrino Nucleus Scattering (CEνNS), has the potential to settle this debate due to …

From ambivalence to activism: Australia and the negotiation of the 1968 Nuclear Non-Proliferation Treaty
… and early interpretation of the 1968 Nuclear Non-Proliferation Treaty (NPT), an instrument which remains the most important global nuclear arms control measure in international law. Using data from recently released Australian government documents, the study analyses the process by which …

Interferences between non-proliferation and science: ‘exporting’ dual-use know-how and technology in conformity with security imperatives
… 3 illuminates the role of knowledge from a proliferation point of view. What are the obligations stemming from legally binding treaties for industry and academia? The chapter also offers a comparative analysis of the multilateral export control regimes including main principles, control …

Nuclear non-proliferation regime effectiveness : an integrated methodology for analyzing highly enriched uranium production scenarios at gas centrifuge enrichment plants
… on the effectiveness of the existing nuclear non-proliferation regime. Furthermore, the success of the Pakistani Gas Centrifuge Enrichment Technology (GCET)- based nuclear weapons program has imposed a great challenge on the Nuclear Nonproliferation Treaty (NPT) regime. In this context, this …

Cooperation on non-proliferation: An analysis of the Treaty of Tlatelolco and the Latin American and Caribbean Nuclear-Weapon-Free Zone (NWFZ)
… effective to tackle nuclear threats and nuclear proliferation and what factors can explain it? To answer this inquiry, we analysed multidimensionally the nuclear capabilities and non-proliferation preferences of Mexico, Argentina and Brazil between 1947 and 1997, and the performance of the Agency …

A unified risk-Informed framework to assess the proliferation risk and license the proliferation performance of nuclear energy systems
In order to strengthen the current non-proliferation regime it is necessary to guarantee high standards of security for the sites that use, store, produce, or reprocess special nuclear materials (SNM). The current surge of interest in nuclear energy requires resolution of concerns about the …

A proof of principle nuclear forensics technique for determining ²³⁵U enrichment from UF₆ steel cylinders
Non-proliferation of nuclear materials depends on international regulations and the inspection tools available to safeguard inspectors for ensuring adherence to international treaties such as the Non-Proliferation Treaty (NPT). In collaboration with Dr. Michael P. Short (MIT) and the Mesoscale …

Rethinking Nonproliferation: Reforming the IAEA and Deterring NPT Withdrawal
… vitality and effectiveness of the nuclear non-proliferation regime (NPR) is threatened on several fronts. The International Atomic Energy Agency (IAEA), charged with monitoring compliance of states‟ nonproliferation obligations, has been incapable of enforcing these commitments or applying …

Uranium Enrichment Signatures of Fluorinated Epoxy
… component of enforcing the international non-proliferation regime. However, while there are well defined forensic techniques for estimating and verifying the production of plutonium, there are currently no such techniques for the production of enriched uranium, despite the fact that many …

An analysis of plutonium accountability in the COPRECAL process
In the late 1970's, emphasis on non-proliferation forced suspension of all commercial spent-fuel reprocessing. The spent-fuel storage problem plaguing the nuclear industry can be alleviated by reprocessing. For commercial spentfuel reprocessing to again become a reality, a process is needed to …

Development of an isotope-sensitive warhead verification technique using nuclear resonance fluorescence
… Despite obligations under the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) to make 'good-faith efforts' to disarm their nuclear arsenals, the United States and Russia still maintain thousands of nuclear warheads. Progress towards complete disarmament has been gradual due to a …

THE CONFRONTATION OVER IRAN’S NUCLEAR PROGRAMME: NATURE, SCOPE, AND LEGALITY
The international nuclear proliferation regime generally and the Nuclear Non- Proliferation Treaty (NPT) in particular were created to prevent nuclear war and promote global security. However, it can be argued that the NPT has become as much a political instrument by which major states advance …

Impact assessment for the MIT Research Reactor low enrichment uranium fuel fabrication tolerances
In the framework of non-proliferation policy, the Massachusetts Institute of Technology Reactor (MITR) is planning to convert from highly enriched uranium (HEU) to low enriched uranium (LEU) fuel. A new type of high-density LEU fuel based on a monolithic U-10Mo alloy is being qualified to allow the …

An Agent-Based Model of the International Nuclear System
… Strategic Arms Reduction Treaty and the Nuclear Non-Proliferation Treaty, the last decade has seen a growing number of states in possession of nuclear weapons. As states enter and exit the nuclear proliferation arena, a set of rules (implicit and otherwise) guide each action. These actions have …

A framework for comparing nuclear warhead authentication protocols
… of strategic stability and international non-proliferation efforts. New treaties are necessary to build upon, or at least maintain, the status-quo, and will rely upon verification technologies and protocols to ensure all sides are dismantling their warheads as promised. The nuclear weapon …

Examination of the proposed conversion of the U.S. Navy nuclear fleet from highly enriched Uranium to low enriched Uranium
.The Treaty on the Non-Proliferation of Nuclear Weapons creates a loophole that allows a non-nuclear-weapon country to avoid international safeguards governing fissile materials if it claims that the materials will be used for naval nuclear propulsion purposes. The United States ability to …

A dynamic multi-criteria analysis of spent-nuclear-fuel alternatives
… vector cost. With regard to the objectives of non-proliferation and non-diversion, occupational and population exposure, uranium resource conservation, and fuel cycle economics. the major conclusion is to use the spent fuel for further energy production, preferably via a combination of extended …

Observation of Reactor Antineutrinos with the CHANDLER Detector
… been searching for the sterile neutrino, but none can claim either its discovery or fully rule it out. To test the sterile neutrino hypothesis, we search for short baseline oscillations using antineutrinos from nuclear reactors. We have developed a reactor antineutrino detection technology …
