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.
Robotics & Remote Systems
The Mission of the Robotics and Remote Systems Division is to promote the development and application of immersive simulation, robotics, and remote systems for hazardous environments for the purpose of reducing hazardous exposure to individuals, reducing environmental hazards and reducing the cost of performing work.

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).

On Friday, March 11, 2011, one of the largest earthquakes in the recorded history of the world occurred on the east coast of northern Japan. This earthquake also generated a major tsunami, causing nearly 20,000 deaths. Electricity, gas and water supplies, telecommunications, and railway service were all severely disrupted and in many cases completely shut down. These disruptions severely affected the Fukushima Daiichi nuclear power plant, causing a loss of all on-site and off-site power and a release of radioactive materials from the reactors.
The leadership of the American Nuclear Society commissioned the American Nuclear Society Special Committee on Fukushima to provide a clear and concise explanation of what happened during the Fukushima Daiichi accident, and offer recommendations based on lessons learned from their study of the event. The American Nuclear Society, a professional organization of 11,600 nuclear science and technology professionals, has a strong tradition of advancing nuclear safety, and the Special Committee on Fukushima was organized to further its members' interests in this important professional obligation.
The release of this report is the culmination of a nearly year-long effort by Special Committee members to analyze a range of factors related to what happened at the Fukushima Daiichi facility. The report was officially released at a press conference held on March 8, 2012 at the National Press Club in Washington, DC. ANS Executive Director Robert Fine made opening remarks and introductions. Drs. Dale Klein and Mike Corradini, the Special Committee co-chairs, lead the discussion of the report and the Q&A session. Special Committee members Paul Dickman — who also served as study director — and Jacopo Buongiorno, lead for regulatory issues, also appeared on the discussion panel.
ANS Special Committee Co-Chairs Dale Klein, Ph.D., former chairman of the Nuclear Regulatory Commission, Michael Corradini, Ph.D., Wisconsin Distinguished Professor of nuclear engineering and engineering physics at the University of Wisconsin, and Eric Loewen, Ph.D., President of the American Nuclear Society, discuss the goals of the ANS Special Committee on Fukushima in interviews at the 2011 ANS Annual Meeting:
