Comments on Final EisDecisionThe United States has produced DUF6since the early 1950s as part of the process of enriching natural uranium for both civilian and military applications. Production took place at three gaseous diffusion plants (GDPs), first at the K 25 site (now called ETTP) at Oak Ridge, Tennessee, and subsequently at Paducah, Kentucky, and Portsmouth, Ohio. The K 25 plant ceased enrichment operations in 1985, and the Portsmouth plant ceased enrichment operations in 2001.
