ANS joins others in seeking to discuss SNF/HLW impasse
The American Nuclear Society joined seven other organizations to send a letter to Energy Secretary Christopher Wright on July 8, asking to meet with him to discuss “the restoration of a highly functioning program to meet DOE’s legal responsibility to manage and dispose of the nation’s commercial and legacy defense spent nuclear fuel (SNF) and high-level radioactive waste (HLW).”

We discuss the technology developed at the Lebedev Physical Institute for the manufacture of hollow microspheres polyethylene terephthalate (PETP). The microspheres are produced by means of foaming solid PETP granules containing CO2 blowing agent in a vertical free-fall furnace. The diameter of obtained microspheres ranges from 50 to 800 µm, with aspect ratio typically from 10 to 50. Reasonably high maximum rupture strengths and relatively low permeabilities have been measured. These properties allow PETP microspheres to be used for long-duration storage of gases and in the technology of cryogenic targets for the ICF program.
