Anna Armstrong is a M.S. student in NSSPI who is working with Dr. Sunil Chirayath to investigate safeguards approaches of Molten Salt Reactors (MSRs) in collaboration with Oak Ridge National Laboratory (ORNL). The research work is primarily sponsored by US-DOE’s National Nuclear Security Administration. This work involves radiation transport modeling and fuel burnup simulations of two types of MSRs (a fast neutron spectrum and thermal neutron spectrum) to compute the inventory of Special Nuclear Material (SNM) production and flow rates in MSRs. SNM quantification will support the development of safeguards approaches by investigating options for nuclear material accounting and control at these types of “bulk material handling” reactors compared to usual “item facility” type PWRs, BWRs and FBRs.
Before joining NSSPI, Armstrong received a Bachelor of Science in Nuclear Engineering with a minor in Radiological Health Engineering from Texas A&M University. Armstrong also interned with the late Senator Daniel Inouye of Hawaii on Capitol Hill and with the United States Secret Service in Washington D.C. where she accompanied Special Agents on Head of State and U.S. President protective missions and also served on the Critical Infrastructure Committee Cyber Security Sector during the 2013 Presidential Inauguration National Special Security Event (NSSE).
