Summary
Advanced Molten Salt Reactors (MSRs) are being developed around the world to close the nuclear fuel cycle and ensure long-term, reliable sources of energy. Unlike traditional solid fueled reactors, the liquid nature of the MSR reactor core lends itself to online reprocessing for the extraction of fissile material isotopes including uranium-233 and plutonium-239. To reduce proliferation concerns and support the widespread deployment of these technologies, systems and methods enabling near-real time determination of the fissile material content within the core are currently needed. To this end, we report development of a field-portable sample dissolution, chemical separation, and alpha/gamma spectrometry system for near-real time actinide analyses from highly radioactive molten salt samples. The system enables rapid, in-field forensic evaluation of radioactive molten salt samples, thereby enabling verification of reactor operator declarations.
