“…These codes are extremely useful for criticality safety and overall fuel cycle analysis and can be used to support safeguards and MC&A for fixed-fuel applications. However, the fluid nature of saltfueled MSRs has required modifications to SCALE (Betzler, Powers, and Worrall 2017) and prompted new tool development, TRANSFORM (Michael S. Greenwood 2018). TRANSFORM is a system-level modeling tool that allows for dynamic inventory tracking of specified fission products as a function of reactor operating conditions.…”

Molten salt reactors (MSRs) are an attractive advanced reactor technology because of their increased fuel utilization and efficiency, the ease of fueling, and the potential to use alternative fuel cycles, including thorium and breeder/burner scenarios. Since an MSR has never been domestically operated for commercial electricity production, minimal infrastructure exists to support performance and materials testing, reactor licensing (including research, test, and operating reactors), and technology development in general. These factors could present challenges for the commercialization of the proposed design technology. Several research and development efforts and investments have begun to identify and supplement the infrastructure to accommodate the molten salt concept, including the United States Department of Energy Office of Nuclear Energy Molten Salt Reactor Program. This report reviews safeguards technology and domestic infrastructure to support the evaluation of nuclear safeguards (primarily material control and accounting) measures and approaches for salt-fueled MSRs. Recommendations for potential priority infrastructure investments, including safeguards measurement test beds and future research, are presented.
