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.

Toroidal rotation and ion temperature validation studies utilizing an X-ray imaging crystal spectrometer (XICS) and charge exchange spectroscopy (CES) are continuously investigated from previous experiments as part of an International Tokamak Physics Activity Diagnostics Working Group Joint Experimental Activity. Core toroidal rotation and ion temperature measurements of different impurity species from XICS and CES diagnostics have shown good agreement again with various plasma discharges from KSTAR. The experimental results from the XICS diagnostic show detailed toroidal rotation behavior due to improved time resolution.
