In 1943, the Oak Ridge facilities were constructed near Knoxville, Tennessee. As was the purpose of the majority of nuclear facilities during this time, Oak Ridge was tasked with developing an atomic bomb. Three facilities were built:
• K-25, also referred to as the Oak Ridge Gaseous Diffusion Plant, enriched uranium. Today, it is the Eastern Tennessee Technology Park (ETTP).
• Y-12 separated uranium using an electromagnetic process.
• X-10, also referred to as Oak Ridge National Laboratory, converted uranium into plutonium.
Nuclear workers from the Oak Ridge facilities have been included in many NIOSH studies. Below are fact sheets that summarize some of the study findings for workers.
