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.

Three types of moisture monitors: MCM Model Dewluxe-20, Panametrics Model System One, and Shaw Model SHA-TRS were tested for accuracy and speed of response over low (10–50 ppm H2O), medium (100–500 ppm H2O), and high (500–4,000 ppm H2O) concentration ranges. The results for the three instruments tested (one of each kind) showed that the MCM instrument was generally more accurate and responded more quickly than the other two instruments, with the Panametrics instrument being less accurate (except at low concentration) and slower to respond, and the Shaw instrument was the least accurate and least responsive of the three instruments during the tests made.
