Y-12 National Security Complex, Oak Ridge Tennessee

 

Y-12Y-12 National Security Complex

 

Y-12 is a DOE facility for August 13, 1942 to the present so workers are eligible to file both Part B and Part E claims.

Y-12 has four Special Exposure Cohorts which covers specific workers with specific cancers and at least 250 days of employment for March 1943-December 31, 1957.

Built in a rural section of East Tennessee, the Y-12 National Security Complex, previously known as the Oak Ridge Y-12 Plant, was part of the Manhattan Project. Its job was to process uranium for the first atomic bomb. Construction of Y-12 started in February 1943; enriched uranium production started in November of the same year. Construction, however, was not entirely finished until 1945.The first site mission was the separation of uranium-235 from natural uranium by the electromagnetic separation process. The magnetic separators were taken out of commission at the end of 1946 when gaseous diffusion became the accepted process for enriching uranium.

Since World War II, the number of buildings at Y-12 has doubled. Its missions have included uranium enrichment, lithium enrichment, isotope separation and component fabrication. For more than 50 years, Y-12 has been one of the DOE weapons complex’s premier manufacturing facilities. Every weapon in the stockpile has some components manufactured at the Y-12 National Security Complex.

Throughout the course of its operations, the potential for beryllium exposure existed at this site, due to beryllium use, residual contamination, and decontamination activities.
