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).”

Niobium deuteride samples are exposed to vacuum sparks with plasma temperatures exceeding 10 keV and a density of >1023 cm−3. An investigation of the surfaces of the niobium deuteride samples by scanning electron microscopy reveals clear signs of surface melting, orifices, bubbles, blisters, and cracks. The surface features are explained in terms of a very high vapor pressure of deuterium forming in niobium at temperatures near its melting point. Vacuum sparks touching the surfaces for ∼1 µs may expel most of the deuterium from the surface region.
