In 2002, the Department decided to permanetly shutdown the Hanford Site Fast Flux Test Facility, FFTF. Since the FFTF was the last sodium-cooled reactor remaining in the United States, the decision involved significant debate within and outside the Department and a series of reviews going back to the early 1990s. The shutdown, as directed by the Department, will encompass three activites- deactivation, decontamination and decommissioning.
