The Sodium-cooled Fast Reactor (sfr)
نویسنده
چکیده
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 intermediatesized (150 to 500 MWe) sodium-cooled fast reactors with uranium-plutonium-minor-actinidezirconium metal alloy fuel, supported by a fuel cycle based on pyrometallurgical processing in colocated 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. On the reactor side, demonstration of passive safety and improvements in inspection and serviceability will be emphasized.

An SPND (Self-powered Neutron Detector) is commonly used for neutron detection in NPP (Nuclear Power Plant) by virtue of un-reactivity for gamma-rays. But it has a drawback, which is that it cannot detect neutrons in real time due to beta emissions (about > 48 s) after reactions between neutrons and Rh in an SPND. And Generation IV reactors such as MSR (Molten-salt reactor), SFR (Sodium-cooled ...
