NRC issues draft EA/FONSI for Duane Arnold restart
Efforts by NextEra Energy to restart the Duane Arnold nuclear power plant as early as 2029 continue to move forward with the Nuclear Regulatory Commission's preliminary environmental assessment and determination that the restart would have no significant environmental impacts.
On Thursday, the NRC posted a draft environmental assessment and a finding of no significant impact for the Palo, Iowa, facility; the Federal Register notice was published on Monday. The Department of Energy’s Office of Energy Dominance Financing is a cooperating agency on the draft EA, as the DOE is considering providing financial assistance to the restart project.

The tritium trick technique was used to build-up radiogenic helium inside stainless steel 12Cr18Ni10Ti (SS). A great quantity of defects with a mean diameter of 20 nm, most probably platelet-like bubbles with 3He atoms, was observed in 3He-containing samples. The mean density of these bubbles in SS samples containing ~75 appm of 3He is estimated to be 61020 m-3. Much larger helium bubbles were observed in SS after annealing the samples at T1170 K. Thermal release of radiogenic helium occurs at T>1500 K. The presence of 3He in structural materials causes the formation of an additional state for hydrogen sorption.
