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.
Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

Resurrecting Three Mile Island
When Exelon Generation shut down Three Mile Island Unit 1 in September 2019, managers were so certain that the reactor would never run again that as soon as they could, they had workers drain the oil out of both the main transformer and a spare to eliminate the chance of leaks. The company was unable to find a buyer because of the transformers’ unusual design. “We couldn’t give them away,” said Trevor Orth, the plant manager. So they scrapped them.
Now they will pay $100 million for a replacement.
The turnaround at the reactor—now called the Crane Clean Energy Center—highlights two points: how smart Congress was to step in with help to prevent premature closures with the zero-emission nuclear power production credit of 0.3 cents per kilowatt-hour (only two years too late), and how expensive it is turning out to be to change course.
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.
