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.
ANS Young Members Group Spotlight on National Labs
July 16, 2020|11:00AM–12:30PM (12:00–1:30PM EDT)
Available to All Users
In the sixth installment of the "Spotlight on National Labs"series, attendees will learn about Lawrence Livermore National Laboratory's history and current ongoing research related to nuclear sciences and engineering.
LLNL was created in 1952 as a “new ideas” laboratory to augment the efforts of Los Alamos in accelerating the U.S.’s hydrogen bomb program. Beginning with the vision of Nobel Prize winner and LLNL namesake E.O. Lawrence, the laboratory established a matrix organization that allows experts in various disciplines to assemble as a team and work together to understand and solve complex problems, a distinguishing feature of LLNL that is still in use today. The unique LLNL environment has allowed for advances in many disparate fields, including high performance computing, laser technology, element discovery, and nuclear weapons science and technology.
