LMNT Consulting


Steve Nesbit is a Professional Engineer who founded LMNT Consulting following a distinguished career with Duke Energy Corporation. LMNT Consulting provides support on matters related to nuclear technology, energy, and the environment. The company focuses on the nuclear fuel cycle, advanced nuclear energy systems, and nuclear nonproliferation.

Nesbit’s career at Duke Energy began in 1982 doing nuclear safety analysis. Between 1996 and 2005, he led Duke Energy’s efforts related to the use of mixed oxide (MOX) fuel in its nuclear power reactors as a part of the Department of Energy (DOE) project to dispose of surplus plutonium from nuclear weapons. He also managed used nuclear fuel activities for Duke Energy. Between 2009 and 2018 he was responsible for developing the company’s policy positions related to nuclear power, and interacting with industry and government groups on used fuel management and related issues. In addition to substantial accomplishments in the nuclear utility sector, Nesbit has considerable experience on government projects through his work with Duke Energy and its former affiliate, Duke Engineering and Services. He worked as a DOE contractor on the MOX fuel project as well as other DOE initiatives: the New Production Reactor Project, 1990 to 1992; the Yucca Mountain Spent Nuclear Fuel Disposal Project, 1992 to 1996; and the Centralized Interim Storage Facility Project in 1996. These assignments included managing groups responsible for licensing and safety analysis. He supported the Department of State on outreach to countries with developing nuclear power programs. His plutonium disposition work led to involvement in nuclear nonproliferation issues. He is serving on the International Panel of Experts for the Nuclear Threat Initiative’s 2020 Nuclear Security Index report as he did for the 2016 and 2018 reports.

Nesbit has been involved in spent fuel issues through a number of industry groups and other organizations, including the Nuclear Industry Council (NIC), the Nuclear Energy Institute and the Nuclear Waste Strategy Coalition. He published technical and policy papers on geologic repository seismic design methodology, centralized interim storage, a new used fuel management organization, a proposed waste acceptance queue for shutdown nuclear power reactors, and NIC recommendations for nuclear waste management reform. He testified to the House Energy and Commerce Committee on H.R. 3053, the Nuclear Waste Policy Amendments Act, in 2017 and to the Senate Energy and Natural Resources Committee on S.1234, the Nuclear Waste Administration Act, in 2019.

Nesbit received Bachelor of Science and Master of Engineering degrees in nuclear engineering from the University of Virginia. He is a registered professional engineer in North Carolina. He is a past adjunct faculty member at the University of North Carolina at Charlotte, where he taught nuclear engineering. He is active in the American Nuclear Society (ANS), currently serving on the Board of Directors, the Nuclear Waste Policy Task Force (chair), the Special Committee on Government Relations (vice-chair), the Public Policy Committee (past chair), and the Special Committee on Advanced Reactor Policy. He also chairs the Piedmont Carolinas ANS local section.
