N-SLOPE: A One-Class Classification Ensemble for Nuclear Forensics
… classification is applied here to the field of nuclear forensics, which is the study and analysis of nuclear material for the purpose of nuclear incident investigations. Nuclear forensics data poses an interesting challenge because false positive identification can prove costly and data is often …

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 …

Analysis of surrogate post-detonation urban debris (SPUD) gamma rays and self-attenuation
Despite the importance of post-detonation nuclear forensics, there is a dearth of Standard Reference Materials (SRMs) suitable for such measurements that are traceable back to a national standard. Accordingly, the nuclear forensics community has requested SRMs be produced that mimic the …

The deterrence of nuclear terrorism through an attribution capability
The state of the world is such that the pace of nuclear weapons proliferation appears to be increasing. The growing number of nuclear states and amount of nuclear material available poses a great challenge to those that would attempt to keep nuclear weapons out of the hands of terrorists and other …

A kinetic transport model of uranium molecular species formation in a laser ablated plasma plume
Nuclear forensics is a technical field of study concerned with the characterization and interpretation of nuclear materials. A central issue in nuclear forensics is the attribution of nuclear devices based on analysis of post-detonation nuclear debris. The issue is complicated by fractionation …

Uranium Enrichment Signatures of Fluorinated Epoxy
… This potentially allows a way to fill the gap in nuclear forensics regarding uranium enrichment, allowing a more comprehensive verification of fissile material production for nations subject to the non-proliferation treaty.

Interference Effects of Urban Rubble on the Radioanalytical Analysis of Strontium
… that will be encountered in the aftermath of a nuclear incident. In such a situation, it will be important to characterize the isotopes of interest present in the affected area to obtain signatures for nuclear forensics and ensure the appropriate response. Specifically, this research is aimed at …

Nuclear forensic applications of uranium oxide chemistry and morphology
… OF MISSOURI AT AUTHOR'S REQUEST.] The entire nuclear fuel cycle is a chemistry-intensive process, from accessing the raw materials from ore, to enriching and forming the fuels, to the eventual long-term disposition or reprocessing of the spent fuel. This chemistry is vital to nuclear …

Carbon Nanotube Based Dosimetry of Neutron and Gamma Radiation
As the world's nuclear reactors approach the end of their originally planned lifetimes and seek license extensions, which would allow them to operate for another 20 years, accurate information regarding neutron radiation exposure is more important than ever. Structural components such as the …

Investigating methods for the speed-up of intra-lanthanide chromatographic systems
High-purity separations of elements from nuclear forensic samples that are also fast have long been a challenge. The simplest analytical-scale separations for most research are based on relatively slow gravity-fed column chromatography, which trades speed for purity. However, in nuclear forensic …

An Improved Model of Nuclear Debris Analysis Systems in Atmospheric Collection Aircraft
Nuclear treaty verification via the use of nuclear cloud sampling aircraft, such as the US Air Force's WC-135, has been common practice since 1965. But while other verification methods have seen extensive computational models developed to support their mission, a detailed model of airborne cloud …
