Oxidation stability study for field reclamation and refortification of cascade lubrication oil at the Oak Ridge Gaseous Diffusion Plant. Addendum 1

An oxidation stability study of filtered used cascade lubrication oil refortified with 0.51 to 0.60% 2,6-Ditertiary-butyl Paracresol and 0.31% Chevron OLOA-233A produced an oil within specified operating limits. The oil also passed a 1000-hour oxidation stability test. These data were used to establish a monitoring program for successful field reclamation and refortification of a unit in the K-33 building at the Oak Ridge Gaseous Diffusion Plant.
