This Integrated Research Project (IRP) stems from a collaboration among UC Berkeley (the SALT group), MIT, NCSU and ORNL.
This IRP will build a general purpose loop at the MIT research reactor where salt flowing through the loop is irradiated by neutrons from the reactor. The neutrons interact with the salt to create various radionuclides in the salt including tritium, helium and noble metal fission products—depending upon the salt being irradiated. The loop creates conditions similar to those in the primary coolant circuit of salt-cooled reactors, to allow experimenters to (1) understand salt behavior in a reactor, (2) test redox control and other chemistry control systems designed to minimize corrosion, (3) test salt cleanup systems, (4) test instrumentation systems and other equipment for salt reactors, and (5) collect data to validate models of radionuclide transport in salt systems.
In the scope of the project, the SALT research group will develop systems to measure and control salt chemistry and tritium transport in the loop.
