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 operation of the ITER machine requires the implementation of two sets of coil systems installed inside the vessel - the edge-localized mode (ELM) coil system and the vertical stabilization (VS) coil system. The ELM coils generate resonant magnetic perturbations in order to reduce high power deposition in the divertor induced by ELM heating and can as an option be used to control moderately unstable resistive wall modes (RWM). The VS coils provide fast vertical stabilization of the plasma. There are three ELM coils in each 40 degrees vacuum vessel (VV) sector; one each in the lower, middle and upper segments for a total of twenty seven individually powered coils. ELM coils are 6-turn rectangular coils. There are two VS coils in the VV, in the lower and upper segments below and above the lower and upper ELM coils respectively. Each upper or lower VS coil is made with 4 turns independently fed for failure recovery in the event of a faulted turn. The In-Vessel Coils (IVCs) and feeders are placed under the blanket shield modules and manifolds and need to be compatible with them. An integrated design concept has been developed that provides for an integrated design of the IVCs and their feeders, the blanket manifolds and the blankets and their respective attachment features to the VV.
