Editing Fast-neutron reactor (section)

====United States====
*[[Clementine (nuclear reactor)|Clementine]] was the first fast reactor, built in 1946 at [[Los Alamos National Laboratory]]. It used plutonium metal fuel, mercury coolant, achieved 25&nbsp;kW thermal and used for research, especially as a fast neutron source.
*[[Experimental Breeder Reactor I]] (EBR-I) at Argonne West, now [[Idaho National Laboratory]], near [[Arco, Idaho]], in 1951 became the first reactor to generate significant amounts of power. Decommissioned in 1964.
*[[Fermi 1]] near [[Detroit]] was a prototype fast breeder reactor that powered up in 1957 and shut down in 1972.
*[[Experimental Breeder Reactor II]] (EBR-II) at [[Idaho National Laboratory]], near [[Arco, Idaho]], was a prototype for the Integral Fast Reactor, 1965–1994.
*[[SEFOR]] in Arkansas, was a 20 [[MWt]] research reactor that operated from 1969 to 1972.
*[[Fast Flux Test Facility]] (FFTF), 400 MWt, operated flawlessly from 1982 to 1992, at [[Hanford Site|Hanford]] Washington. It used liquid sodium drained with argon backfill under care and maintenance.
*[[Sodium Reactor Experiment|SRE]] in California, was a 20 [[MWt]], 6.5 MWe commercial reactor operated from 1957 to 1964.
*[[LAMPRE-1]] was a molten plutonium fueled 1 MWth reactor.  It operated as a research reactor from 1961 to 1963 at Los Alamos national Lab.
