The FFTF is a liquid-sodium-cooled research and test reactor with a mixed fuel of uranium oxide and plutonium oxide. It was completed in 1978 and was at full operation in 1982. “Fast flux” refers to the speed of neutrons moving through the reactor during the fission process. The facility was built to test fuels and materials to expedite the nuclear power production process, but in 1993, DOE determined that the reactor was not worth the $100 million annual upkeep. It has been deactivated and its sodium coolant drained. It is still standing at the Hanford site, pending a final decision on decommissioning activities for the reactor and its support buildings.
