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).”

The separation of tritiated sources from the exhaust stream of a nuclear fusion system remains a key area of study. While current hydrogen isotope separation technologies are effective at separating gaseous elemental hydrogen, they require additional costly and time-intensive electrolysis steps to be applied toward tritiated water. Previous work has proposed a capture and exchange method, which this work has applied to screen for an optimal weight loading of platinum onto a zeolite molecular sieve. Several samples of various weight loadings were cycled using a series of isotope exchange processes, and it was determined that a weight loading between 0.65 to 0.80 wt% Pt is optimal to separate heavier isotopes of hydrogen from a water waste stream.
