We developed a deep neural network method to predict the composition of the iodine-sulfur process of thermochemical water-splitting hydrogen production using measurable properties. Unlike conventional titration analysis, this approach allows a quick understanding of fluid composition, providing essential information for controlling operating conditions. This study focused on the HI-I$$_{2}$$-H$$_{2}$$O three-component system within the IS process. Using Gibbs phase rule, the DNN model was constructed using online measurable parameters, such as temperature, pressure, and density, as input conditions. The model was trained with experimental data, and the structural parameters were tuned. Composition prediction using actual trend data demonstrated good correlation with titration analysis measurements. Furthermore, the local interpretable model-agnostic explanations method was incorporated to gain insights into the significance of input parameters for compositions from the DNN model, providing valuable information on crucial parameters for effective composition control.

Development of proton exchange membranes for hydriodic acid concentration by ion-track grafting technique

Tanaka, Nobuyuki; Sawada, Shinichi*; Sugimoto, Chihiro; Yamaki, Tetsuya*

QST-M-33; QST Takasaki Annual Report 2020, P. 37, 2022/03

We have been developing the ion exchange membranes by a radiation grafted polymerization method to improve HI concentration performance for Electro-electrodialysis (EED) in the thermochemical water-splitting hydrogen production iodine-sulfur process. We verify to adopt the cation exchange membrane prepared by ion-track grafted technique. In this membrane preparation technique, one-dimensional cylindrical ion-channel can be formed in the base polymer film by the radiation of the heavy ion beam. And, the excess swelling of the ion-channel could be prevented, expecting that the HI concentration performance could be improved. In our works, The HI concentration experiment was conducted by the electric cell assembled the membrane prepared by the ion-track grafting technique. The HI composition of the tested solution increased, indicating that the tested membrane can operate HI concentration by EED.

R&D of a MW-class solid-target for spallation neutron source

R&D works for MW class solid target composed of tungsten to produce pulsed intense neutron source has been made in order to construct a future scattering facility. Three methods were investigated to prevent corrosion of tungsten from water; those are hipping, brazing and electric coating in molten salt bath. Hipping condition was optimized to be 1500 degree C in the previous work: here small punch test shows highest load for crack initiation of hipped materials at the boundary of W/Ta. The basic techniques for the other two methods were developed. Erosion test showed that uncovered W is susceptible of flowing water velocity. At high velocity w is easy to be eroded. For solid target design slab type and rod type targets were studied. As long as the optimized neutron performance is concerned, 1MW solid target is better than mercury target.
