“…However, there has also been considerable research on crystallisation behaviour of terrestrial basaltic glasses [33] [34] as well as their physical/chemical [35] and magnetic [36] properties. Practical applications of synthetic basalt glass are, for example, basalt fibre reinforced concrete [37] or immobilisation of transuranic wastes [38].…”

International space agencies are aiming to establish permanent outposts on the lunar surface. For that purpose, new technologies and equipment are being developed which will enable and augment these mission goals. To increase the duration of a long-term planetary mission and to expand mission capabilities, the ability to manufacture transparent glass in-situ could be an important enabler on the lunar surface. Results presented in this work show that it is feasible to use different lunar regolith simulants to manufacture optically transparent glass by magnetically beneficiating regolith prior to processing. Beneficiated regolith simulant was melted, cast into glass nuggets which were then ground, lapped and polished into glass slides of 1mm thickness. The glass slides' surface roughness and geometry were measured, prior to optical analysis, which showed an average transmission of about 80 % of light in the wavelength range from 250 to 1250 nm. A comparable reference glass sample performed only about 9 % (absolute) better on average. From these results it seems viable to manufacture transparent glass from actual lunar regolith on the lunar surface as well, however, differences in regolith simulant and actual regolith still need to be fully explored -Regolith may be available on the lunar surface in unlimited quantities and therefore open up new strategic possibilities.

“…Durability studies on the devitrified ISV waste forms have shown that the devitrified products do not adversely affect the chemical durability (Lokken 1982, Timmons 1996. This is probably because the formation of diopside and wollastonite crystals during devitrification decreases the concentration of CaO while increasing the concentration of SiO, in the residual glassy phase for silica-rich soils.…”

Portions ABSTRACTThe objective of this report is to recommend a waste form program plan that addresses waste form issues for mixed low-level waste (MLLW). The report compares the suitability of proposed waste forms for immobilizing MLLW in preparation for permanent near-surface disposal and relates them to their impact on the U.S. Department of Energy's mixed waste mission. Waste forms are classified into four categories: high-temperature waste forms, hydraulic cements, encapsulants, and specialty waste forms. Waste forms are evaluated concerning their ability to immobilize MLLW under certain test conditions established by regulatory agencies and research institutions. The tests focused mainly on leach rate and compressive strength. Results indicate that all of the waste forms considered can be tailored to give satisfactory performance immobilizing large fractions of the Department's MLLW inventory. Final waste form selection will ultimately be determined by the interaction of other, often nontechnical factors, such as economics and politics. As a result of this report, three top-level programmatic needs have been identified: (1) a basic set of requirements for waste package performance and disposal; (2) standardized tests for determining waste form performance and suitability for disposal; and (3) engineering experience operating production-scale treatment and disposal systems for MLLW.iv
