Can hydrogen be the transportation fuel in an otherwise nuclear economy?
Let’s face it: The global economy should be powered primarily by nuclear power. And it probably will by the end of this century, with a still-significant assist from renewables and hydro. Once nuclear systems are dominant, the costs come down to where gas is now; and when carbon emissions are reduced to a small portion of their present state, it will become obvious that most other sources are only good in niche settings. I mean, why use small modular reactors to load-follow when they can just produce that power instead of buffering it?

Cement-based salt concrete (mass concrete with crushed salt filler) and MgO (sorel) concrete are the building materials used for seals in repositories in salt formations. These structures are important elements to prevent the access of aqueous solutions to emplaced waste containments. The post-closure evolution of such cements is studied in detail at GRS in order to understand the long-term changes in their hydraulic conductivity. This includes CHM-coupled interactions between the concrete material and the host rock and formation water. This paper presents results from laboratory investigations of the sealing capacity of seal systems at laboratory scale in contact with various saline solutions.
