Currently, spent nuclear fuel (SNF) from commercial power plants is stored in stainless-steel canisters for interim dry storage. To provide an inert environment, these are backfilled with helium after vacuum drying. However, the environment may be contaminated during extended storage because of material degradation. For example, heavier fission gas xenon released rods into canister cavity should cladding breached. Other gases such as air and water vapor also present a result leakage caused by chloride-induced stress corrosion cracking on walls or insufficient Therefore, monitoring composition can critical information about health SNF canisters. In this study, noninvasive testing was conducted 2/3-scaled mock-up using acoustic sensing. Ultrasonic transducers were placed exterior surface to probe composition. A dataset collected sealing introducing up 1.53% argon 1.29% background gas. Three methods used detect changes composition: time-of-flight (TOF) method, differential autoencoder method. Results showed that TOF method had sufficient resolution abnormal concentrations less than 1.0%. The demonstrated periodic in-phase out-of-phase behavior between benchmark (i.e., pure helium) air) state signals. variational (VAE) Wasserstein (WAE) trained data applied directly data. It found both unsupervised VAE WAE able distinguish states based reconstruction error.
