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.
Dr. Joseph R. Dietrich served as president of the American Nuclear Society (ANS) from 1977-1978. In addition, he served on the Society’s Board of Directors from 1958 to 1961, and again from 1977 to 1980. He was a Fellow of ANS.
Dr. Dietrich was internationally known for a pioneering career in nuclear power reactor development that spanned more than thirty years.
He was born on August 25, 1914 and began his nuclear career in 1946, when he joined the Daniels Pile development project in Oak Ridge, Tennessee. In 1948, he moved to Argonne National Laboratory, where he was in charge of reactor physics and shielding design for the prototype nuclear power plant for the Nautilus, the first nuclear-powered submarine. At Argonne he was also in charge of the planning, theory, and experimental instrumentation for the BORAX experiments, at the conclusion of which he directed the physics work for the experimental boiling water reactor. During 1953-54, Dietrich took part in the first large-scale reactor safety experiments at the National Reactor Testing Station.
In 1956, with the founding of General Nuclear Engineering Corporation, he joined the company as a vice president. Later, after the company had been purchased by Combustion Engineering, Inc., Dietrich became chief scientist in Combustion Engineering’s Nuclear Power Systems Division, a position he held until his retirement in February 1980.
Dr. Dietrich earned his BS in physics and chemistry from the College of William and Mary in Williamsburg, and MS and PhD in physics from University of Virginia in 1937 and 1939, respectively.
Dr. Joseph R. Dietrich passed away on November 4, 1982.
