Thermal-hydraulic analysis of innovative fuel configurations for the sodium fast reactor
The sodium fast reactor (SFR) is currently being reconsidered as an instrument for actinide management throughout the world, thanks in part to international programs such as the Generation-IV and especially the Global Nuclear Energy Partnership (GNEP). The success of these programs, in particular …

Increasing proliferation resistance of sodium fast reactor fuel cycle through use of a nuclear resonance fluorescence detector
The proliferation resistance of a reprocessing facility can be improved by using a novel detection system that utilizes the nuclear resonance fluorescence (NRF) phenomenon to determine the isotopic composition of materials flowing through the plant. In an aqueous reprocessing facility, the waste …

Anti-proliferation safeguard system for General Electric's PRISM reactor plant
… are to be built in the future. The PRISM nuclear reactor system has been examined in this work with focus on the movement of nuclear fuel. The PRISM was chosen as the system to develop a proliferation safeguard system because of the literature that has been readily available for it and its …

Modeling and Analysis of Actinide Diffusion Behavior in Irradiated Metal Fuel
There have been numerous attempts to model fast reactor fuel behavior in the last 40 years. The US currently does not have a fully reliable tool to simulate the behavior of metal fuels in fast reactors. The experimental database necessary to validate the codes is also very limited. The …

Modeling special nuclear material diversion from a pyroprocessing facility
… for its capabilities separating both light water reactor (LWR) and metallic fuels, and inherent proliferation resistance. However, unlike aqueous reprocessing plants, industrial pyroprocessing plants do not yet exist. Similar to safety-by-design in next-generation reactors, reprocessing facilities …

Mechanical characterization of alloy 709 stainless steel after high temperature aging for application in advanced reactors
Sodium fast reactors are among the leading generation IV nuclear reactor designs being studied for future development. They will operate at higher temperatures and have higher neutron fluxes and thus require the use of novel materials. These materials will need to withstand an extreme environment, …

Reactor protection system design alternatives for sodium fast reactors
… basis events that can significantly challenge sodium-cooled fast reactors. The perceived potential consequences of a severe unprotected transient in a sodium-cooled fast reactor include an energetic core disruptive accident, vessel failure, and a large early release. These consequences can be …

Conceptual design of a breed & burn molten salt reactor
A breed-and-burn molten salt reactor (BBMSR) concept is proposed to address the Generation IV fuel cycle sustainability objective in a once-through cycle with low enrichment and no reprocessing. The BBMSR uses separate fuel and coolant molten salts, with the fuel contained in assemblies of …
