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.
