Research questionHow can we estimate a strongly coupled reactor’s full internal state from three noisy external measurements across operating and accident scenarios?Strong coupling between reactor neutronics and thermal hydraulics makes internal fields difficult to infer when only a few noisy measurements are available. The challenge is to recover unmeasured quantities reliably as system conditions change.

Latest papersRecent research connected to this question, newest first.Towards Efficient Parametric State Estimation in Circulating Fuel Reactors with Shallow Recurrent Decoder NetworksThe evidence concerns a Molten Salt Fast Reactor test case, with neutron fluxes, precursor concentrations, temperature, pressure, and velocity reconstructed from three out-of-core time-series neutron-flux measurements alone. The study covers parametric operating and accidental scenarios and considers uncertainty quantification and real-time use, but does not establish performance beyond this test setting.research paper · Sep 4, 2026
