Oak
Ridge Thermal Diffusion Plant
Oak Ridge Thermal Diffusion Plant is a DOE facility for 1944-1952 so workers are eligible to fil for Part B and Part E claims.
There is a Special Exposure Cohort which covers all workers with specific cancers and at least 250 days of employment from July 9, 1944 through 1951.
The S-50 Plant at Oak Ridge was constructed in 1944 to
enrich uranium feed material for the Y-12 electromagnetic
facility using a liquid thermal diffusion process. The
process was originally developed at the Naval Research
Laboratory in Washington, DC, and tested on a pilot plant
level at the Philadelphia Naval Shipyard. Located near the
K-25 gaseous diffusion facility, the S-50 Plant operated for
a limited period during 1944-1945. The plant was closed in
September 1945 because the thermal diffusion process was not
as efficient as the gaseous diffusion.
The S-50 plant was reopened in 1946 as part of the joint
Air Force/AEC project to investigate the possibility of
developing a nuclear-powered airplane. This project, known
as Nuclear Energy for the Propulsion of Aircraft (NEPA), was
housed at S-50 and the contractor was the Fairchild Engine
and Aircraft Corporation. Fairchild's NEPA Division at S-50
conducted a number of experiments involving beryllium powder
during the time period 1946-1951.
The S-50 Plant at Oak Ridge was constructed in 1944 to enrich uranium feed material for the Y-12 electromagnetic facility using a liquid thermal diffusion process. Oak Ridge Thermal Diffusion Plant was one of three Manhattan Project uranium enrichment plants and was located at the Clinton Engineer Works in Oak Ridge, Tennessee. It was adjacent to the K-25 plant. It began operation on September 16, 1944 and was shut down on September 9, 1945.
Alternative Name
DOL
DOL provides Part B and Part E statistics on S-50. DOL also has Site Exposure Matrix for S-50 but lists it under S-50 rather than Oak Ridge Thermal Diffusion Plant.
NIOSH
NIOSH lists statistics for S-50's dose reconstructions. NIOSH has a webpage on Oak Ridge Facilities. NIOSH has developed technical basis documents for S-50 and has information on S-50's Special Exposure Cohorts.
