Fukushima’s Future for the Realization of SDGs

Abstract

To depict "Fukushima's future for the realization of SDGs," it is necessary to proceed with the decommissioning of the Fukushima Daiichi Nuclear Power Plant (1F) without delay. We are developing "the insoluble neutron absorbers" for the purpose of preventing recriticality of fuel debris as one of the 1F decommissioning technologies. By applying worm-like micelles, we were able to spread the slurry carrying boron carbide, which is a neutron absorber, on the simulated fuel debris in water. We evaluated the radiation resistance of worm-like micelles and found the possibility of application in the primary containment vessel. We have also confirmed the ability to absorb neutrons, and it is expected that this technology will have an effect in preventing recriticality of fuel debris. Unexpected technology is needed for the reconstruction of Fukushima, and I think that there is a technology that Japan Oil Chemists' Society can contribute to in the future.
