CX-020784: Fuel Salt Sampling Technology Development – Vanderbilt University and University of Michigan

Vanderbilt University (VU), in collaboration with the University of Michigan (UM), proposes to develop and demonstrate a modern equivalent to the Molten Salt Reactor Experiment (MSRE) Sampler-Enricher (S-E) that allows reactor operators to sample the hot fuel salt as well as insert additional fuel salt and control materials. The tasks associated with this project are (1) Complete a comprehensive investigation of historical molten salt system technical documentation to fully characterize the modern day (MD) S-E interfacing systems and functional requirements; (2) Develop an initial MD S-E conceptual design that incorporates modern-day technological advances, design standards, and previous molten salt system experience; (3) Perform reliability modeling of MD S-E concurrently with design development process; (4) Create initial physical prototype of conceptual MD S-E design; (5) Perform preliminary testing of MD S-E at VU LASIR facility; (6) Perform design changes and develop second iteration physical prototype (if necessary); (7) Perform comprehensive testing of revised prototype in molten salt environment; and (8) Assess performance and reliability of the final MD S-E prototype. Existing laboratory facilities will be used.
