To date, most fast neutron reactors have been liquid metal cooled and so are called liquid metal cooled fast reactors (LMFRs). When configured as a breeder reactor (e.g. with a breeding blanket [ definition needed ] ), such reactors are called liquid metal fast breeder reactors (LMFBRs).
The integral fast reactor (IFR), originally the advanced liquid-metal reactor (ALMR), is a design for a nuclear reactor using fast neutrons and no neutron moderator (a "fast" reactor). IFRs can breed more fuel and are distinguished by a nuclear fuel cycle that uses reprocessing via electrorefining at the reactor site.
A sodium-cooled fast reactor is a fast neutron reactor cooled by liquid sodium. The initials SFR in particular refer to two Generation IV reactor proposals, one based on existing liquid metal cooled reactor (LMFR) technology using mixed oxide fuel (MOX), and one based on the metal-fueled integral fast reactor .
The reactor is a sodium-cooled fast reactor, which uses liquid sodium as the coolant. [4] It uses two separate sodium loops, and these are connected to a main water-cooled loop which feeds the steam generators and turbines for producing electricity. [7] The sodium coolant is pressurized to 5.5 MPa, and is heated to over 500 °C in the reactor. [6]
Schematic diagram showing the difference between the loop and pool designs of a liquid metal fast breeder reactor. The pool-type has greater thermal inertia to changes in temperature, which therefore gives more time to shut down/SCRAM during a loss of coolant accident situation. The reactor is a pool type LMFBR with
English: A schematic of the two types of liquid metal fast breeder reactor (LMFBR), a fast neutron reactor designed to breed fuel by producing more fissile material than it consumes. FBRs are used in nuclear power plants to produce nuclear power from nuclear fuel. LMFBRs are cooled by liquid sodium, but other metals have been used in the past.
The RAPID-L design is a liquid metal fast breeder reactor (LMFBR) concept meant to prevent accidents due to human errors. The goal was to create a long-life core that is inherently safe due to being maintenance free. These were necessary requirements as the reactor was intended to be used on the Moon. [1] [3] [4]
