“…4 Oak Ridge National Laboratory (ORNL) had begun experimental demonstration of remote pump maintenance in support of commercial MSR deployment using hot cell tooling by 1958. 5 Fixtures were designed and added to a high temperature pump to permit making and breaking all service lines en bloc and replacing the rotor element; all of this was accomplished using a manipulator while observing via a camera with a monitor (see Figure 1). In 1959, ORNL constructed a non-nuclear full-scale physical mock-up of an MSR with prototypic materials and temperatures to develop and demonstrate remote O&M capabilities (see Figure 2).…”

Remote, highly automated operations and maintenance tools (O&M) are crucial for economically successful deployment of molten salt reactors (MSRs). Liquid-fueled MSRs will have high dose rates within containment following initial start-up due to the proximity of the fuel salt and gaseous fission products. The challenges of performing O&M in high dose environments have long been recognized, and many of the required technology components have been developed for use in similar high radiation environments.To be competitive, future MSRs need to have much lower labor costs than existing nuclear power plants. The advance of digital technologies provides the opportunity to automate maintenance activities. Advances in modeling and simulation (M&S) may enable the role of the operator to be shifted from remote task performance to oversight of automated systems. Dynamically updating a plant's digital twin representation through integrating multiple sensor signals will be key to automating complex process tasks. Since complex, highly automated maintenance in high radiation areas has not been proven, adequate demonstration is required to validate its performance.
