Remembering ANS member Gil Brown
Brown
The nuclear community is mourning the loss of Gilbert Brown, who passed away on July 11 at the age of 77 following a battle with cancer.
Brown, an American Nuclear Society Fellow and an ANS member for nearly 50 years, joined the faculty at Lowell Technological Institute—now the University of Massachusetts–Lowell—in 1973 and remained there for the rest of his career. He eventually became director of the UMass Lowell nuclear engineering program. After his retirement, he remained an emeritus professor at the university.
Sukesh Aghara, chair of the Nuclear Engineering Department Heads Organization, noted in an email to NEDHO members and others that “Gil was a relentless advocate for nuclear energy and a deeply respected member of our professional community. He was also a kind and generous friend—and one of the reasons I ended up at UMass Lowell. He served the university with great dedication. . . . Within NEDHO, Gil was a steady presence and served for many years as our treasurer. His contributions to nuclear engineering education and to this community will be dearly missed.”
Donald Hoffman is the current president and CEO of EXCEL Services Corporation. He founded EXCEL Services Corporation in 1985 to provide specialized professional services to nuclear utilities in licensing, regulatory support, and operational areas.
Hoffman is very active in the nuclear industry and served as the 59th president of the American Nuclear Society. He is the Chair of the Virginia Nuclear Energy Consortium Authority which is charged with the responsibility for making the Commonwealth a national and global leader in nuclear energy and to serve as an interdisciplinary study, research, and information resource for the Commonwealth on nuclear issues. He is the Co-Chair of the ANS Special Committee on Nuclear in the States which shall identify and review: state and regional-opportunities for new nuclear development in the US; state-level legislative and regulatory barriers preventing such development; federal policies that have a direct impact on state level decision-making; lessons learned from the new nuclear development projects currently under construction, and determine the best course forward. He is also the president of Eagle Alliance, a U.S. based grassroots organization that represents all facets of nuclear science and technology.
Prior to starting EXCEL, Hoffman served in the U.S. Nuclear Submarine Navy as a senior reactor operator and engineering officer. He was a branch chief and a lead reviewer at the Nuclear Regulatory Commission reviewing license applications and technical specifications.
Hoffman has been a member of ANS since 1984, has served on the Board of Directors, and has been an active member of many divisions and committees.
He received his degree in Nuclear Engineering and Technology in 2010 from Excelsior College in New York.
He continues to make presentations and provide testimony regarding the benefits of nuclear science and technology to the U.S. Congress, the U.S. Governors, the National Governors Association, and other U.S. organizations.
