Division Spotlight
Young Members Group
The Young Members Group works to encourage and enable all young professional members to be actively involved in the efforts and endeavors of the Society at all levels (Professional Divisions, ANS Governance, Local Sections, etc.) as they transition from the role of a student to the role of a professional. It sponsors non-technical workshops and meetings that provide professional development and networking opportunities for young professionals, collaborates with other Divisions and Groups in developing technical and non-technical content for topical and national meetings, encourages its members to participate in the activities of the Groups and Divisions that are closely related to their professional interests as well as in their local sections, introduces young members to the rules and governance structure of the Society, and nominates young professionals for awards and leadership opportunities available to members.

ARPA-E announces $40 million to develop transmutation technologies for UNF
The Department of Energy’s Advanced Research Projects Agency–Energy (ARPA-E) announced $40 million in funding to develop cutting-edge technologies to enable the transmutation of used nuclear fuel into less-radioactive substances. According to ARPA-E, the new initiative addresses one of the agency’s core goals as outlined by Congress: to provide transformative solutions to improve the management, cleanup, and disposal of radioactive waste and spent nuclear fuel.
As vice president of nuclear strategy & development for Exelon, Marilyn Kray leads major initiatives on current and advanced reactor designs to create growth opportunities that leverage Exelon’s nuclear operations competency. These initiatives include pursuing operational service agreements, both domestically and internationally, as well as engaging with advanced reactor developers in order to evaluate potential business opportunities and future technology deployment.
She served as president of NuStart Energy Development LLC, an industry consortium formed to develop the process for preparing the combined construction and operating license applications for the first new nuclear plant construction in the United States in over 30 years.
Her in-depth knowledge of the global nuclear industry comes from years of experience including as vice president of Exelon Nuclear Partners. In this role, she led international business development. Prior to this, she served as Exelon’s vice president of nuclear acquisition support, where she pioneered internal processes for due diligence and plant transitions. The result was the successful purchases of the Three Mile Island, Clinton, and Oyster Creek generating stations. More recently, she led the acquisition of the FitzPatrick nuclear power plant.
Marilyn began her career with Exelon in the licensing organization for the Peach Bottom Atomic Power Station. Prior to joining Exelon, she was a reactor engineer and project manager for the U.S. Nuclear Regulatory Commission. She has testified in front of Congress on multiple occasions regarding nuclear development in the United States. Throughout her career Marilyn has served in leadership roles as Exelon’s representative to the Nuclear Energy Institute and the Electric Power Research Institute.
Marilyn has been a member of ANS since 2007 and serves in the Education, Training, and Workforce Development Division as well as the Operations and Power Division. In 2007, she received the American Nuclear Society’s Utility Leadership Award. Other recognitions Marilyn has received include the World Nuclear Association award for Distinguished Contribution to the Peaceful Use of Nuclear Technology, and under her leadership the NuStart organization was one of four finalists for the 2012 Edison Award.
Marilyn is a graduate of Carnegie-Mellon University, with a Bachelor of Science degree in Chemical Engineering.
