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).”

Double oxide layers were observed on the stainless steel coupons. The outer layer consisted of well-developed crystals (diameter: 0.5 to 1.0 üm, probable major oxide form: NiO Fe2O3), while the inner layer consisted of smaller particles [diameter: 0.1 to 0.3 μm, probable major oxide form: NiO-(Cr,Fe)2O3]. The depletion of chromium and nickel and the accumulation of impurities in the water, such as 60Co, zinc, and copper, were observed in the outer layer. For the carbon steel the chromium-rich layer existed at the outer/inner interface. It was considered that the outer and inner layers were a corundum-type oxide (Cr,Fe)2O3. The outer layer seemed to be formed by a wet corrosion mechanism (dissolution-precipitation of metal), while the inner layer seemed to be formed by a dry corrosion one (reaction of metal with oxygen diffused through the oxide layers from the water). More than 80% of the 60Co in a coupon was included in the outer layer, and it was supposed that this was deposited mainly during wet corrosion.
