Getting back to yes: A local perspective on decommissioning, restart, and responsibility
For 45 years, Duane Arnold Energy Center operated in Linn County, Ia., near the town of Palo and just northwest of Cedar Rapids. The facility, owned by NextEra Energy, was the only nuclear power plant in the state.
In August 2020, a historic derecho swept across eastern Iowa with winds approaching 140 miles per hour. Damage to the plant’s cooling towers accelerated a shutdown that had already been planned, and the facility entered decommissioning soon after, with its fuel removed in October of that year. Iowa’s only nuclear plant had gone off line.
Today the national energy landscape looks very different than it did just six short years ago. Electricity demand is rising rapidly as data centers, artificial intelligence infrastructure, advanced manufacturing, and electrification expand across the country. Reliable, carbon-free baseload power has become increasingly valuable. In that context, Linn County has approved the rezoning necessary to support the recommissioning and restart of Duane Arnold and is actively supporting NextEra’s efforts to secure the remaining state and federal approvals.

Five years have passed since the Broader Approach (BA) activities launched in 2007 under the framework of collaboration between Japan and EURATOM. In the International Fusion Materials Irradiation Facility (IFMIF) Engineering Validation and Engineering Design Activities (EVEDA) project, commissioning of the prototype lithium test loop was completed in March 2011, and a lithium flow of 25 mm thick at 15 m/s was obtained in July 2012. Components of the prototype accelerator are being fabricated. Injector will be delivered in Rokkasho in March 2013 followed by the validation test of the accelerator. In the International Fusion Energy Research Center (IFERC) project, five R&Ds mainly on DEMO blanket are being carried out at a newly constructed DEMO R&D facility. A high performance supercomputer with a LINPAC performance of 1.27 Pflops is now operational for the fusion simulation. In the Satellite Tokamak Program (STP) project, JT-60 torus disassembly is almost completed, and manufacture of tokamak components such as PF coils, vacuum vessel, cryostat are being fabricated on schedule. JT-60SA construction will start in Dec.2012. Present status and recent achievements of these BA activities are summarized.
