Professor Arden Rowell was part of an interdisciplinary team of University of Illinois researchers raising concerns about a proposed rule that could reduce environmental oversight for advanced nuclear reactors. The group submitted a public comment to the U.S. Department of Energy about a rule that would allow certain advanced reactor activities—including siting, construction, operation, and decommissioning—to proceed without standard environmental reviews. The team concluded the U.S. Nuclear Regulatory Commission should not adopt the Department of Energy’s characterization of advanced reactors as technologies that normally have no significant environmental impacts.

The College of Law was well-represented at the recent St. Louis University Colloquium on Law, Behavioral Science, and Social Science. Professor Jennifer Robbennolt presented a work-in-progress called “’The Rule of Law’ Silo” that is co-authored by Professors Verity Winship and Colleen Murphy. The paper presents the results of a survey to understand what people understand the phrase “the rule of law” to mean.

The federal government’s moves to reform the rules surrounding nuclear energy plants might have had the effect of streamlining the process of bringing new reactors online and, thus, creating more nuclear energy for the United States’ power grid. Federal agencies making changes behind closed doors, without input from experts, has chilled scientists, however. Moving quickly and creating uncertainty, Professor Arden Rowell tells Science, could backfire and slow progress.

Working with an interdisciplinary team of nuclear engineers, Professor Arden Rowell coauthored a public comment submitted to the Nuclear Regulatory Commission in response to its proposed “Sunset Rule.” The rule had proposed “sunsetting” ten regulatory rules addressing nuclear safety.

Many recent changes in rules and regulations surrounding nuclear power reactors have been enacted with the goal of expanding the use of nuclear technology, but the shifts also run the risk of overwhelming the Nuclear Regulatory Commission and threatening the industry. In a new editorial published by Nuclear Newswire, Professor Arden Rowell and a team of nuclear engineers from the University of Illinois attempt to answer urgent questions in order “to prevent industry-wide paralysis and ensure that new nuclear power reactors are deployed both safely and efficiently.”

Professor Arden Rowell was awarded the 2025 Carroll P. Hurd Award for Scholarly Excellence for her paper, “Indoor Environmental Law,” 54 Environmental Law 101 (2024). The Carroll P. Hurd Award for Scholarly Excellence was established in 2002, by Michael Moore and Heidi Hurd, in honor of Heidi’s father, Carroll Parsons Hurd, whose work as a political theorist and lawyer elevated theoretical curiosity and intellectual rigor above all other virtues. Rowell accepted the award during the annual faculty retreat on May 15, 2025.

The “Dear Colleague Letter” issued by the U.S. Department of Education in February expressed a threat that schools that support diversity initiatives could face funding cuts. With several cultural houses on campus, University of Illinois Urbana-Champaign could be among the targets to lose funding. In an extensive examination, Illinois Public Media quotes both Dean Jamelle Sharpe and Professor Arden Rowell on how the letter may affect the Illinois campus and the levels of uncertainty that exist currently. “The Department is taking a very aggressive and expansive view of the Supreme Court’s decision,” Sharpe said. “They believe it should be applied to situations that the Supreme Court’s decision itself did not address.”

Americans spend nearly 90% of their time indoors, yet current environmental laws do not regulate indoor air quality. The Regulatory Review recently analyzed a recent article from Professor Arden Rowell in which she argues that effective environmental policies should include indoor environments, as existing regulations like the Clean Air Act only cover outdoor air, creating a patchwork of inadequate protections. She advocates for comprehensive federal regulations to address indoor air quality, emphasizing that such measures are essential for safeguarding human health as outdoor environments become more hazardous.

Professor Arden Rowell has teamed up with the Socio-Technical Risk Analysis (SoTeRiA) Research Laboratory, led by Nuclear, Plasma, & Radiological Engineering Associate Professor Zahra Mohaghegh on a new research grant from the Nuclear Regulatory Commission (NRC). The grant, titled “Context-Based Analysis of a Risk-informed, Performance-based Regulatory Approach for Advanced Nuclear Reactors,” will span from 2024 to 2027. The project aims to help the NRC—the agency responsible for regulating the safety of civilian nuclear reactors—identify how to effectively use its aging statutory mandates to address new and emerging nuclear technologies. 

Professor Arden Rowell, an expert in environmental law, administrative law, risk regulation and human behavior, has joined the faculty of the Beckman Institute or Advanced Science and Technology. In addition to her work at the College of Law, Rowell will share her expertise with students of Beckman and continue her collaborative work with the faculty and researchers there. Rowell’s recent collaborations at Beckman have focused on work with Zahra Mohaghegh, an associate professor of nuclear, plasma, and radiological engineering.
