Sodium-Cooled Fast Reactor (SFR).

摘要

The Sodium-cooled fast reactor (SFR) features a closed fuel cycle for efficient conversion of fertile uranium and management of minor actinides. A full actinide-recycle fuel cycle is envisioned with two major options: One involves intermediate-sized (150 to 500 MWe) sodium-cooled fast reactors with uranium-plutonium- minor-actinide-zirconium metal alloy fuel, supported by a fuel cycle based on pyrometallurgical processing in co-located facilities. The second involves medium to large (500 to 1500 MWe) sodium-cooled reactors with mixed uranium-plutonium oxide fuel, supported by a fuel cycle based upon advanced aqueous processing at a centralized location serving a number of reactors. Owing to the number of sodium fast reactors built and demonstrated around the world, and thus their technological maturity, the primary focus of the R&D is on the recycle technology and economics of the overall system.
