U-M leading $25M program to advance nuclear nonproliferation

Topic: Campus News

Advancing technologies to identify bomb-making nuclear materials, ferret out secret nuclear weapons facilities and detect nuclear detonations anywhere in the world is the aim of a new $25 million program led by the University of Michigan and funded by the Nuclear National Security Administration.

The effort brings together 14 universities and 13 national laboratories. It has the dual purpose of demonstrating new ways to catch terrorists and nations that are acting in violation of nuclear treaties and also developing the nuclear security workforce.

Through the program — known as the Consortium for Monitoring, Technology and Verification, or MTV — at least 200 students will have the opportunity to work on the cutting edge of nuclear nonproliferation — on big international projects or more speculative concepts.

“The national laboratories are experiencing a large number of retirements of skilled and experienced workers, so there is an urgent need for young people to be trained in these areas and connected with the national laboratories,” said Sara Pozzi, director of the new program and professor of nuclear engineering and radiological sciences. “The majority of the funds will go to student fellowships, internships and travel.”

The research efforts will be aligned along three “thrusts”:

Thrust 1: Particle detection

Sample project: WATCHMAN, a U.S.-U.K. collaboration, is developing an underground detector for ethereal particles that can travel straight through Earth. These “antineutrinos,” produced in reactors, can reveal whether a reactor is running or not — and engineers can use the operating schedule to deduce whether a reactor is being used to produce weapons-grade plutonium. It may be possible to monitor reactors from hundreds of miles away. MTV students will do research related to antineutrino detection in WATCHMAN.

Thrust 2: Detecting secret production of nuclear weapons

Nuclear nonproliferation inspectors take samples inside nuclear facilities to look for evidence of weapons-related activity. Should they be picking up samples from outside the facilities as well? Researchers will look for changes in plants and living things that might take in or interact with materials released from nuclear activities, perhaps revealing uranium enrichment or plutonium separation.

Thrust 3: Enhancing global monitoring for nuclear explosions

Sample project: A global network of sensors already watches for nuclear explosions, but it could be more accurate if it had more data, giving a truer picture of a nation’s nuclear weapon capabilities. One type of sensor collects infrasound data, or sound waves with frequencies below human hearing. The RedVox app harnesses the microphones on smartphones as infrasound listening devices, exploring the possibility of crowdsourcing data.

The MTV follows on the success of the Consortium for Verification Technology, led by Pozzi for the past five years. This consortium developed new detectors and methods for verifying nuclear treaties while recruiting and training nearly 300 students.

Other members of the MTV leadership team are Shaun Clarke, associate director and associate research scientist in nuclear engineering and radiological sciences, and David Wehe, chief scientist and professor of nuclear engineering and radiological sciences.

Igor Jovanovic, professor of nuclear engineering and radiological sciences, is the associate director for the national laboratories within MTV and the lead for Thrust 1. Steven Biegalski, professor of nuclear and radiological engineering at Georgia Tech, leads Thrust 2. Milton Garçes, a researcher at the University of Hawaii at Mãnoa, leads Thrust 3.

Other university participants are MIT, Princeton, Columbia, Wisconsin, Texas A&M, New Mexico, Penn State, Florida, Virginia Tech and Tennessee.

Participating national labs are Argonne National Laboratory, Brookhaven National Laboratory, Idaho National Laboratory, Lawrence Berkeley National Laboratory, Lawrence Livermore National Laboratory, Los Alamos National Laboratory, Nevada National Security Site, Oak Ridge National Laboratory, Pacific Northwest National Laboratory, Princeton Plasma Physics Laboratory, Sandia National Laboratories, Savannah River National Laboratory and Y-12 National Security Complex.
