Matthew Denman: On Probabilistic Risk Assessment
Matthew Denman
Probabilistic risk assessment is a systematic methodology for evaluating risks associated with a complex engineered technology such as nuclear energy. PRA risk is defined in terms of possible detrimental outcomes of an activity or action, and as such, risk is characterized by three quantities: what can go wrong, the likelihood of the problem, and the resulting consequences of the problem.
Matthew Denman is principal engineer for reliability engineering at Kairos Power and the chair of the American Nuclear Society and American Society of Mechanical Engineers Joint Committee on Nuclear Risk Management’s Subcommittee of Standards Development. As a college student at the University of Florida, Denman took a course on PRA but didn’t enjoy it, because he did not see its connection to the nuclear power industry. Later, during his Ph.D. study at the Massachusetts Institute of Technology, his advisor was Neil Todreas, a well-known thermal hydraulics expert. Todreas was working on a project with George Apostolakis, who would leave MIT to become a commissioner of the Nuclear Regulatory Commission. The project, “Risk Informing the Design of the Sodium-Cooled Fast Reactor,” was a multi-university effort funded through a Department of Energy Nuclear Energy Research Initiative (NERI) grant. Todreas and Apostolakis were joined in this project by a who’s who of nuclear academia, including Andy Kadak (MIT, ANS past president [1999–2000]), Mike Driscoll (MIT), Mike Golay (MIT), Mike Lineberry (Idaho State University, former ANS treasurer), Rich Denning (Ohio State University), and Tunc Aldemir (Ohio State University).
Educational Session|Panel|Sponsored by Business/Economic Performance

Session Organizer:
Maria Hernandez (Duke Energy)
Track Organizer:
Timothy Schlimpert (MCR Group)
Knowledge Manager:
Amber Von Ruden (Exelon Corporation)
This session will review recent operating cost data to analyze the nature of current spending, evaluate trends in spending and identify those areas most likely to provide opportunities for improvement in the future. Maria Hernandez, Nuclear Corporate Finance Manager for Duke Energy and Timothy Schlimpert, Vice President, MCR Performance Solutions will complete and present the analyses. Supporting data is collected and provided for analysis by the Electric Utility Cost Group (EUCG); the only organization collecting robust industry cost data. All information is provided blinded to protect the confidentiality of all data contributors. For more on the EUCG visit: www.eucg.org
