“…Additional analogue observations regarding bulkheads in Canada and other case studies are reported by Eyermann, Van Sambeek, and Hansen (1995). An experience at the Rocanville mine involved drift seal construction of brine-based concrete, analogous to possible panel closure construction for a salt repository room or panel.…”

This report summarizes the state of salt repository science, reviews many of the technical issues pertaining to disposal of heat-generating nuclear waste in salt, and proposes several avenues for future science-based activities to further the technical basis for disposal in salt. There are extensive salt formations in the forty-eight contiguous states, and many of them may be worthy of consideration for nuclear waste disposal. The United States has extensive experience in salt repository sciences, including an operating facility for disposal of transuranic wastes. The scientific background for salt disposal including laboratory and field tests at ambient and elevated temperature, principles of salt behavior, potential for fracture damage and its mitigation, seal systems, chemical conditions, advanced modeling capabilities and near-future developments, performance assessment processes, and international collaboration are all discussed. The discussion of salt disposal issues is brought current, including a summary of recent international workshops dedicated to high-level waste disposal in salt.Lessons learned from Sandia National Laboratories' experience on the Waste Isolation Pilot Plant and the Yucca Mountain Project as well as related salt experience with the Strategic Petroleum Reserve are applied in this assessment. Disposal of heat-generating nuclear waste in a suitable salt formation is attractive because the material is essentially impermeable, self-sealing, and thermally conductive. Conditions are chemically beneficial, and a significant experience base exists in understanding this environment. Within the period of institutional control, overburden pressure will seal fractures and provide a repository setting that limits radionuclide movement. A salt repository could potentially achieve total containment, with no releases to the environment in undisturbed scenarios for as long as the region is geologically stable. Much of the experience gained from United States repository development, such as seal system design, coupled process simulation, and application of performance assessment methodology, helps define a clear strategy for a heat-generating nuclear waste repository in salt.iv ACKNOWLEDGMENTS

“…Different studies on the long-term compressive strength of concrete made with seawater discovered that there is almost no difference to that of concrete mixed with freshwater [50][51][52]. Other mixtures of concrete and salt were developed for the protection of radioactive waste in abandoned salt caves [53][54][55][56][57], here salt comprised around 50% of the whole mass [53].…”

3D Printing for Construction With Alternative Materials

Sustainable materials and additive manufacturing have the potential to increase material efficiency and minimize waste in the building process. One of the most promising materials is salt (sodium chloride). It is highly available as a residue of desalination and potash production processes and attracts attention due to its material properties (storage of humidity and heat). This research presents an investigation and evaluation of using salt as an alternative material in additive manufacturing. Thus, the focus of the study was on small-scale 3D printing with paste extrusion. Experimental studies of different salt mixtures with different binders, printing properties and other parameters were analyzed in three stages. In the first phase (P1) the mixing ratio of salt and potential binders (clay, gypsum, cement and starch) was defined; in the phase two (P2) the most promising mixture was selected, modified by additives and investigated by 3D image scan measurements; and in the last third phase (P3) the potential applications of salt in additive manufacturing were presented. As the research shows, the salt in material extrusion processes can substitute the main material by up to 70%, is successfully manipulated with different additives (to improve the workability of the printing mortar) and is highly dependent on the printer`s settings. For future full-scale 3D printing with salt many steps still have to be taken. However, incorporating salt in additive manufacturing showed a potential of saving material resources, addressing environmental issues and initiating new construction processes.
