INMM Member at Large Kerry DunnMember at Large
Kerry Dunn
Kerry A. Dunn, a Senior Advisory Engineer within the Nuclear Materials Management directorate at the Savannah River National Laboratory, is an internationally recognized expert in the area of plutonium materials management and storage including behavior of nuclear materials, age-related degradation, corrosion, treatment, packaging, and transportation.  She has been instrumental in developing and implementing the U.S Department of Energy (DOE) programs for the interim storage of plutonium materials including the associated surveillance programs.  In this role, Kerry has lead the team of researchers and engineers which has developed the body of scientific and engineering models and data to validate the technical basis for the safe interim storage of these materials.  In these areas, Kerry also worked with INMM’s Journal of Nuclear Materials Management (JNMM) during 2010-2011 to develop and publish two special issues of the JNMM focused on plutonium storage and surveillance and containing 21 seminal peer reviewed articles in this area. The articles, seven of which were authored or co-authored by Kerry, described a comprehensive scientific work from the Plutonium Storage and Surveillance Program which provides the understanding of age-related degradation processes and materials performance for long-term storage of plutonium materials. 
In addition, Kerry also leads the DOE-NNSA programs on the removal of plutonium worldwide to support U.S. threat reduction initiatives.  She has led the successful efforts in over half dozen countries, working with facility owners and regulators, to stabilize, package and remove plutonium materials for ultimate disposition.  Her work has directly led to announcements of successful project completion by the respective national leaders at each of the Nuclear Security Summit since 2012.  Most recently, Kerry was named the National Pillar for cross cutting activities associated with the U.S High Performance Research Reactor (USHPRR) Convert Program which is focused on HEU (high enriched uranium) minimization, also for the DOE NNSA. 

Currently, Kerry is the President of the INMM Southeast Chapter and prior to that served as the Vice President of the INMM Southeast Chapter.  She has been a member of INMM for the past 7 years, is a Senior Member of the Institute and has been active in the annual meeting each year organizing papers and chairing sessions.  Equally important, she has been instrumental in engaging early career staff in INMM activities and helping the SE Chapter become more vibrant.

Outreach projects are performed in Central and South-East Asia, Africa, South-America and Middle-East.

The Nuclear Security unit operates several experimental nuclear safeguards laboratories and a nuclear emergency crisis room on the Ispra site in North of Italy. There are 6 major activities in the unit, which cover non-destructive analysis of nuclear materials, physical modelling (incl. Monte Carlo) and process monitoring of nuclear fuel cycle facilities, sealing technologies, verification technologies and methodologies, assessment methodologies for non-proliferation and nuclear security (incl. open source intelligence, strategic trade control, disarmament verification etc) and monitoring of radioactivity in the environment (incl. emergency information management and reporting systems ECURIE/EURDEP) .
