ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Radiation Protection & Shielding
The Radiation Protection and Shielding Division is developing and promoting radiation protection and shielding aspects of nuclear science and technology — including interaction of nuclear radiation with materials and biological systems, instruments and techniques for the measurement of nuclear radiation fields, and radiation shield design and evaluation.

Matthew Denman: On Probabilistic Risk Assessment
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 Maintenance and Work Management
Tuesday, August 11, 2020|11:00AM–12:30PM (12:00–1:30PM EDT)|5
Jon Anderson (ACA Proactive)
Pete Arthur (INPO)
John McDonald (INPO)
Bryant Hearne (INPO)
Saieed Ahmed (Exelon Corporation)
This session starts with a discussion by Brandon Jenewein on the Work Management Simplification South Texas Project is implementing. This project will result in a significant reduction in personnel through “automated” Functional Equipment Group (FEG) Long-Term Scheduling. Brandon will be supported in this discussion by Jon Anderson, Tim Johnson, and Richard Jackson, three suppliers that are helping with this project. Pat Schotter from Palo Verde will discuss their TeMPO project and significant savings through automation. Topics will include Work Order Screening, Recurring Task Generation, Risk Reviews, Material Requests, etc. Scott Lappegaard from Xcel will discuss the automations they are working on including, Ready to Work Repetitive Work, including Master Tagouts, Model Work Orders, Correct Spare Parts, etc. Pete Arthur, John Mc Donald and Bryant Hearne from INPO will be supporting.
