    ABSTRACT Globally, the production, transport and storage of nuclear materials have led to serious concerns over illegal trafficking of such materials. Ukraine stands at one of the geographical crossroads of such activities, and contains the largest uranium ore reserves in Europe. Moreover, Ukraine retains significant waste from Soviet-era uranium production and enrichment activities, as well as radioactive materials accumulated from the Chernobyl catastrophe. Lawrence Livermore National Laboratories (LLNL), with support through NA-242, has initiated multiple cooperative efforts within Ukraine, engaging some of the best Ukrainian scientists and institutions in nuclear forensic science. Nuclear forensics serves as a vehicle for scientific collaborations between the Ukrainian and United States governments, strengthening the response and core capabilities of Ukraine, who is also taking an active role as the regional leader in nuclear forensics, and additionally contributing to further engagements between respective governments. These collaborations are being supported through the Department of Energy, NA-242 GIPP (Global Initiatives for Proliferation Prevention) and CBM (Confidence Building Measures) programs, and serve to enhance nuclear forensics capabilities for Ukraine and neighboring countries, as well as in the United States. INTRODUCTION Ukraine stands at a geographical and geopolitical crossroads for illicit trafficking of nuclear materials, possessing the largest uranium ore reserves in Europe, as well as retaining significant waste from Soviet-era uranium production and enrichment activities, and radioactive materials accumulated from the Chernobyl catastrophe. Additionally, Ukraine supports a large uranium mining industry founded on a diverse set of geological settings and employing multiple uranium mining technologies, from open-pit to leach field mining. According to the illicit trafficking database maintained by the International Atomic Energy Agency (IAEA) [1,2], over the past two decades, more than one thousand cases have been confirmed by States Points of Contact, about 25% of which involved nuclear materials.
