Aging Performance of Viton

Radioactive material packages used for transportation of plutonium-bearing materials often contain multiple O-ring seals for containment. Packages such as the Model 9975 are also being used for interim storage of Pu-bearing materials at the Savannah River Site (SRS). One of the seal materials used in such packages is Viton® GLT fluoroelastomer. The aging behavior of containment vessel O-rings based on Viton® GLT at long-term containment term storage conditions is being characterized to assess its performance in such applications. This paper summarizes the program and test results to date.Copyright © 2007 by Washington Savannah River Company LLC
