In response to the expansion of nuclear fuel cycle (NFC) activities -- and the associated suite of risks -- around the world, this project evaluated systems-based solutions for managing such risk complexity in multimodal and multi-jurisdictional international spent nuclear fuel (SNF) transportation. By better understanding systemic risks in SNF transportation, developing SNF transportation risk assessment frameworks, and evaluating these systems-based risk assessment frameworks, this research illustrated interdependency between safety, security, and safeguards risks is inherent in NFC activities and can go unidentified when each "S" is independently evaluated. Two novel system-theoretic analysis techniques -- dynamic probabilistic risk assessment (DPRA) and system-theoretic process analysis (STPA) -- provide integrated "3S" analysis to address these interdependencies and the research results suggest a need -- and provide a way -- to reprioritize United States engagement efforts to reduce global nuclear risks. Lastly, this research identifies areas where Sandia National Laboratories can spearhead technical advances to reduce global nuclear dangers.

Understanding Risks in the Global Civilian Nuclear Enterprise: Global Nuclear Assured Security Scenarios Workshop
The purpose of the scenarios workshop held for the Civilian Nuclear component of the Global Nuclear Assured Security Mission Integration Initiative was to identify sources of risk in the global civilian nuclear enterprise. The risks identified are inadequately addressed through current technical measures, regulatory frameworks and institutions and should be considered for further research. The workshop participants also developed four high level scenarios describing different sequences of events that could result in radiological releases, widespread loss of electric power, and loss of public confidence in segments of the nuclear industry. The scenarios are intended for further analysis and as the basis for simulation exercises.
Terry Turbopump Expanded Operating Band Full-Scale Component and Basic Science Detailed Test Plan-Revision 2
This document details the milestone approach to define the true operating limitations (margins) of the Terry turbopump systems used in the nuclear industry for Milestone 3 (full-scale component experiments) and Milestone 4 (Terry turbopump basic science experiments) efforts. The overall multinational-sponsored program creates the technical basis to: (1) reduce and defer additional utility costs, (2) simplify plant operations, and (3) provide a better understanding of the true margin which could reduce overall risk of operations.
