Used Nuclear Fuel Actinide Management in a Sodium- Cooled Heterogeneous Innovative Burner Reactor
<p>This 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 …

The Influence of Preferential Diffusion On the Blow-Off of Laminar Aerated Burner Flames
The blow-off of a laminar aerated burner flame in which Hydrogen is present cannot be characterised by the flame stretch correlation proposed by Reed. A literature review has indicated that the preferential diffusion of Hydrogen towards the point of stability in the region of maximum primary flame …
