The Nuclear Security Science and Policy Institute (NSSPI) and
Los Alamos National Laboratory (LANL) organized a trip to Santa Fe,
New Mexico last week for Texas A&M University nuclear
engineering graduate students and two NSSPI professional staff
members. The trip had two objectives: to attend a one-day 19th
Annual Technical Meeting of the Institute of Nuclear Materials
Management (INMM) Southwest Chapter on May 16th and get hands-on
training on uranium and plutonium measurements on May 17th.
The students, Linda Anuar, Barbara Fisher, Paul Mendoza, Patrick
O'Neal, Athena Sagadevan, Yanuar Ady Setiawan, and Robert Zedric,
are all working in areas focused on nuclear nonproliferation,
security, or safeguards, and they were joined in New Mexico by
three graduate students from the University of New Mexico (UNM)
working in the same areas.
At the INMM Southwest Chapter Technical meeting, Mendoza presented
a paper titled "Neutron energy spectrum-based nuclear forensics
attribution methodology using trace nuclide ratios in weapons-grade
plutonium," and Setiawan presented a paper on "Minimal cut sets
evaluation of modified fault tree method for security system
vulnerability analysis in radiotherapy facility case study." The
meeting was an opportunity for the students to interact with the
INMM southwest regional chapter committee members, as well as share
their research with their peers at another regional
At LANL, the students participated in a training session at the
Nuclear Materials Safeguards Training Facility. They learned
how to perform nondestructive assay of uranium and plutonium using
neutron and gamma measurements applied to safeguards.
The trip was sponsored by LANL through the National Nuclear
Security Administration's Next Generation Safeguards Initiative
(NGSI). NGSI supports the training and development of skilled
professionals in the area of international safeguards as part of
its mission "to develop the policies, concepts, technologies,
expertise, and infrastructure necessary to sustain the
international safeguards system as it evolves to meet new
LANL staff involved in planning the trip included Mark Croce,
Stacey Eaton, James Miller, Laura Osburn, and Alexis Trahan.
NSSPI Director Sunil Chirayath and NSSPI Research Engineer Claudio
Gariazzo accompanied the students on the trip.
