Used Nuclear Fuel Actinide Management in a Sodium- Cooled Heterogeneous Innovative Burner Reactor
… research developed a design of an innovative sodium-cooled fast reactor (SFR) for minor actinide (MA) destruction in used nuclear fuel (UNF). The destruction of MAs would reduce the radiotoxicity of the discharged waste to less than 25% of the once-through cycle after 100 years. The design can …

Applying risk informed methodologies to improve the economics of sodium-cooled fast reactors
… production and for nuclear waste management, the Sodium-Cooled Fast Reactor (SFR) is being developed. The main drawback has been its high capital and operating costs in comparison with traditional light water reactors. In order to compete, the SFR must be shown to be economically competitive. This …

Tools for supercritical carbon dioxide cycle analysis and the cycle's applicability to sodium fast reactors
The Sodium-Cooled Fast Reactor (SFR) and the Supercritical Carbon Dioxide (S-C0₂) Recompression cycle are two technologies that have the potential to impact the power generation landscape of the future. In order for their implementation to be successful, they must compete economically with existing …

Levelized Cost of Fuel (LCOF) studies for microreactors using TRISO fuel in hydride and beryllium-based composite moderators in open and closed fuel cycles
… class of nuclear batteries—high-temperature gas-cooled 10 MW_th microreactors (HTGRs) with TRISO fuel in prismatic- and pebble-bed cores—using four composite moderator concepts (MgO–Be, MgO–BeO, MgO–YH, MgO–ZrH). These options are compared against a prismatic graphite benchmark, under both …

Improvements to the Cheng-Todreas wire-wrapped rod bundle friction factor correlation in response to pin number and in the transition flow region
… correlation for measuring the pressure drop of sodium coolant through a Sodium-Cooled Fast Reactor (SFR). Although CTD is the most accurate correlation, there is room for improvement with new data and modern ways to visualize data and check the accuracy of changes easily. This thesis attempts to …

Development of thermodynamic cycles for sodium-cooled-fast reactors.
… level of 40-62%. As there are six GEN-IV nuclear-reactor concepts and the performance of these reactors-concepts depends on their design, it is reasonable to start with all GEN-IV reactor concepts and investigate the coolants and their characteristics in these concepts. For this objective, main …

Structural and thermodynamic properties of sodium actinide ternary oxides
In the potential event of a clad breach in a Sodium-cooled Fast Reactor (SFR), the sodium metallic coolant could come into contact with the (U,Pu,Np)$O_2$ nuclear fuel. The reaction products are numerous, but there is little knowledge of their structural and thermodynamic properties. Under the …

Diffusion Barrier Coatings for Liquid Metal Corrosion Resistance in Next-Generation Nuclear Reactors
… diffusion barrier coating applied onto nuclear reactor cladding, liquid metal coolants, and metallic fuel used in Sodium-Cooled Fast Reactors (SFRs) and Lead-Cooled Fast Reactors (LFRs). In SFRs and LFRs, damage to cladding and structural materials from the liquid metal coolant poses large …
