Philip Abelson conducted research on the liquid thermal diffusion method of isotope separation at the Philadelphia Navy Yard. This process was utilized for the S-50 Plant at Oak Ridge.

In September 1944, two workers were killed while trying to fix a clogged tube in the transfer room of the liquid thermal diffusion semi-works at the Philadelphia Navy Yard.

Philip Abelson first became involved in uranium enrichment while a graduate student at the University of California-Berkeley, working with cyclotrons under Ernest O. Lawrence. He explains how he came up with the idea that liquid thermal diffusion could enrich uranium-238 to U-235, how this process was implemented first at a factory at the Philadelphia Navy Yard and later at the S-50 Plant in Oak Ridge, and the important role the S-50 Plant played in the uranium enrichment process.
