Progress in Uranium Chemistry: Driving Advances in Front-End Nuclear Fuel Cycle Forensics

Identification of uranium signatures relevant for nuclear safeguards and forensics

The paper describes the applicability of different characteristics (signatures) in nuclear safeguards and forensics for assessment of uranium material provenance in terms of production process. The study follows a uranium ore concentrate production from an ore to a U3O8 product. It turned out that rare-earth elemental pattern, radiochronometry (age of ore body and material production date), sul...

Secondary organic aerosol production from diesel vehicle exhaust: impact of aftertreatment, fuel chemistry and driving cycle

Environmental chamber (“smog chamber”) experiments were conducted to investigate secondary organic aerosol (SOA) production from dilute emissions from two medium-duty diesel vehicles (MDDVs) and three heavyduty diesel vehicles (HDDVs) under urban-like conditions. Some of the vehicles were equipped with emission control aftertreatment devices, including diesel particulate filters (DPFs), selecti...

The key role of the back-end in the nuclear fuel cycle

Dædalus Winter 2010 This two-volume special issue of Dædalus highlights the challenges associated with the global expansion of nuclear power. The topics covered include environmental impacts, nuclear safety, and the economics of nuclear power production, but the major emphasis is on nonproliferation and security aspects. To develop an understanding of possible problems and their potential solut...

Thermal -Hidraolyc Study of Trr Core in Fuel Conversion Frome Highly Enriched Uranium to Low Enriched Uranium Fuel (RESEARCH NOTES)

Safeguarding the Military Naval Nuclear Fuel Cycle

In the safeguards agreements between non-nuclear-weaponstate members of the Nuclear Nonproliferation Treaty and the International Atomic Energy Agency, there is a possibility for non-nuclear weapon states, acting with the approval of the agency’s board of governors, to remove from safeguards nuclear materials to be used in non-proscribed military activities such as naval nuclear propulsion. Thi...
