Abstract
A novel full-digital real-time neutron flux monitor (NFM) has been developed for thorium-based molten salt reactor (TMSR). The system is based on the high-speed, parallel, and pipeline processing of the field programmable gate array as well as the high-stability controller area network platform. A measurement range of 108 counts per second is achieved with a single fission chamber by utilizing the normalization of the count and Campbell algorithms. With the advantages of using the measurement range, system integrity, and real-time performance, digital NFM has been tested in the Xi’an pulsed reactor fission experiments and was found to exhibit superior experimental performance.
