He then welcomed this month’s speaker: Craig Benson from the University of Wisconsin–Madison, who presented “Natural Systems Approach for Closure of Uranium Mill Tailing Facilities.”

My story: Abraham Weitzberg, ANS member since 1962

November 25, 2025, 9:31AMANS NewsAbraham Weitzberg

. . . and today.

Weitzberg then. . .

My first exposure to nuclear engineering was in 1956–57 when I was a fourth-­year chemical engineering undergraduate at MIT. The previous summer, I worked at an oil refinery in New Jersey and our class visited a Monsanto sulfuric acid factory in Boston Harbor. I lost my enthusiasm for chemical engineering and decided to take a couple of introductory nuclear engineering courses as a senior. After a summer job at Y-­12 in Oak Ridge, I started on a nuclear engineering master’s degree program. (An Atomic Energy Commission fellowship certainly helped my decision.)

The following summer, I performed reactor physics experiments at Brookhaven with Herb Kouts, Joe Hendrie, Rudy Sher, and Henry Windsor. In January 1962, after defending my Ph.D. dissertation on measuring uranium-­238 capture in lattices of uranium rods in heavy water, I headed to Los Angeles to work on SNAP reactors for Atomics International. There, I performed critical experiments and managed their aerospace safety program.

Coming up: The 4th annual ARCSC workshop

Mobley

American Nuclear Society member John Mobley IV recently donated some historical nuclear artifacts and memorabilia to the Department of Nuclear Engineering and Radiological Sciences (NERS) at the University of Michigan.

Mobley is a nuclear engineering education researcher at the University of Michigan. Among his roles at ANS, he is currently the secretary of Young Members Group; the vice chair of the Education, Training and Workforce Development Division; and the vice chair of Student Sections Committee.

He said he chose to donate part of his collection to NERS because the University of Michigan is broadly committed to nuclear outreach at the local, state, and federal levels. The university is home of the first ANS Student Section, which turned 70 this year.
