Characterization of an Aged WESF Capsule

摘要

A joint effort by SNLA and ORNL was initiated for a detailed characterization of an 18-year-old WESF exp 137 Cs source which has been used in the Sandia Irradiator for Dried Sewage Solids. The study included evaluation of the inner and outer stainless steel capsules by optical metallography, electron microprobe, and physical testing. Analysis of the residual atmospheres within the two containers was also done. The CsCl was analyzed for isotopic content and impurities. No potential problem areas, including corrosion, were found.
