Nuclear Engineering in Iowa

Iowa's nuclear engineering market of 180 engineers has undergone a significant structural transition following the permanent shutdown of the Duane Arnold Energy Center in 2020 — Iowa's only commercial nuclear power plant, which was originally licensed to operate until 2034 but was shut down early after tornado damage accelerated NextEra Energy's decision to close the facility. This closure reshuffled Iowa's nuclear workforce, with many Duane Arnold engineers relocating or transitioning to adjacent industries, while the state's university research ecosystem and medical nuclear sector have grown to sustain and expand Iowa's nuclear engineering community.

Major Employers: Iowa State University (Ames) has one of the nation's long-established nuclear engineering programs and a research reactor — the Ames Laboratory, co-located with Iowa State, is a DOE national laboratory with nuclear materials research programs. The University of Iowa Hospitals and Clinics (Iowa City) employs nuclear engineers in medical physics, radiation therapy, and nuclear medicine programs. Alliant Energy and MidAmerican Energy (a Berkshire Hathaway company) are evaluating advanced nuclear energy options and employ small numbers of nuclear engineers in energy planning. Rosemont Copper / uranium mining adjacent industries and radiation safety consultancies serve Iowa's industrial sector. Former Duane Arnold employees who remained in Iowa have populated consulting firms, state radiation control offices, and educational institutions across the state.

Key Industry Clusters: Ames anchors Iowa's nuclear research community through Iowa State University and the Ames Laboratory. Iowa City (University of Iowa) is the center of medical nuclear engineering. Des Moines, as Iowa's largest city and home to multiple energy company headquarters, houses energy planning and regulatory affairs nuclear positions. The Cedar Rapids area, near the former Duane Arnold site, retains some nuclear engineering activity through decommissioning support roles and consultancy.

Iowa's nuclear engineering careers have diversified significantly following Duane Arnold's closure, with the state's nuclear workforce now more evenly distributed across research, medicine, energy planning, and environmental/decommissioning niches than the plant-dominated career structure that prevailed before 2020. This diversification, while initially disruptive, has created a more resilient and multi-dimensional nuclear engineering market.
