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.

A diagnostic method for spatial distributions of D-D and D-3He fusion reactions has been developed. Refinement of collimation geometry and choice of a detector and a shielding foil resulted in a drastic improvement of signal separation from noise in collimated proton counting. The developed method was then applied and revealed proton yield distributions in an inertial-electrostatic confinement device running with a D2-3He mixture fuel gas. The result showed localized D-3He reactions on cathode gird surfaces. It also indicated considerable fractions of D-D reactions on anode grid and chamber wall surfaces as well as the cathode grid.
