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.

Sven Bader
Session Organizer:
Fossil uranium is often separated into at least two categories, such as low-enriched uranium (LEU, with <20% U-235), and high-enriched uranium (HEU, with >20% U-235). Occasionally, LEU is further split into categories such as LEU+ (5-10% U-235) and high-assay LEU (10-20% U-235). However, plutonium never appears to be sub-divided into sub-categories, regardless of whether it is, for example, reactor-grade or weapons-grade plutonium. This panel will discuss the pros and cons of potentially dividing plutonium into sub-categories of importance (similar to uranium) and the potential to develop an ANS position statement support this position.
