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 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.
