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.

We demonstrate an automated, space-efficient, low-cost, and rep-ratable setup that delivered complex targets to the target chamber center (TCC) and optimized their position along the laser focal axis at GALADRIEL: the General Atomics LAboratory for Developing Rep-rated Instrumentation and Experiments with Lasers. The focal range optimization and directional orientation (FRODO) tool used a continuous-wave laser to create a focal spot on the target and a camera to reimage the spot using a collinear optical path. A tape drive system spooled an aperture tape with periodically spaced two-photon polymerization (2PP) targets through the TCC, and FRODO tracked the patterns and intensity in the reflected light to determine the locations of apertures and targets, deliver the target to the TCC, and then move them to the position of best focus with accuracy smaller than the Rayleigh length of the 1-TW drive laser. Ablation of 2PP foams on the aperture tape produced nearly twice the >1-KeV X-ray energy as shots on plain Cu tape.
