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.

With the growth of the private fusion industry and a shift in R&D programs toward the engineering aspects of fusion energy systems, the study of neutronics is likely to play an increasingly important role in the overall design of fusion systems. The geometric complexity, deep shielding type problems, and needs for multiphysics integration and uncertainty quantification in fusion systems pose significant methodological challenges to be addressed by the fusion neutronics community. This panel brings together experts from industry, academia, and government laboratories to discuss the current state of fusion neutronics modeling and where challenges lay ahead.
