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 .
TerraPower selected Kemmerer, Wyoming as the site for a 345 MWe Natrium reactor using a molten salt energy storage system. The reactor can temporarily boost output to 500 MWe, enabling the plant to integrate with renewable resources. [9] In June 2024 the site broke ground, beginning preparation for the as-yet unapproved reactor. [10]
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]
The Sodium Reactor Experiment, designed by Atomics International, was one of the chosen reactors. [6] Design of the Sodium Reactor Experiment began in June 1954, and construction was underway in April 1955. A local utility company, Southern California Edison, installed and operated a 6.5 MW electric-power generating system.
The actual reactor would be located in a sealed, cylindrical vault 30 m (98 ft) underground, while the building above ground would be 22×16×11 m (72×52.5×36 ft) in size. This power plant is designed to provide 10 megawatts of electrical power with a 50 MW version available in the future. [3] The 4S is a fast neutron sodium reactor
In May 2005 the core support basket was drilled to drain the remaining sodium coolant, which effectively made the reactor unusable. However, a technical study is being pursued with regard to repairing the reactor. [citation needed] As the coolant was drained, the system was filled with high purity argon gas to prevent corrosion. The support ...
The Experimental Breeder Reactor II. Experimental Breeder Reactor-II (EBR-II) was a sodium-cooled fast reactor designed, built and operated by Argonne National Laboratory at the National Reactor Testing Station in Idaho. It was shut down in 1994. Custody of the reactor was transferred to Idaho National Laboratory after its founding in 2005.
