Two series of borosilicate glasses were prepared for studying the influence of the
substitution of (i) CaO for Na2O and (ii) ZrO2 for SiO2 on glass durability. They were …

The effect of alumina mole fraction on the 7-day Product Consistency Test (PCT) responses,
ln [NL α], of simulated nuclear waste glasses was examined. It was found that the effect is …

Understanding alteration mechanisms of borosilicate glasses in aqueous media is essential
to nuclear waste performance assessments to ensure radioisotopes are contained for …

Numerical simulations of the water dissolution of a random ternary solid are presented. The
three elements represent silica, soluble oxides (alkalis and boron) and quasi-insoluble …

This report reviews literature concerning the relationship between the composition and
durability of silicate glasses, particularly glasses proposed for immobilization of radioactive …

Borosilicate glass is to be used for permanent disposal of high-level nuclear waste in a
geologic repository. Mechanistic chemical models are used to predict the rate at which …

We present a Monte Carlo simulation method for modelling glass dissolution in aqueous
solutions. This simulation method is consistent with transition state theory, and therefore also …

Future reprocessing of nuclear fuel may produce a waste stream consisting of alkali and
alkaline earth fission products that can be converted into stable aluminosilicate minerals …

A percolation phenomenon has been discovered for the dissolution of sodium borosilicate
glasses in aqueous solutions under low‐pH conditions (pH∼ 2). The glasses fall into one of …

The observed relationship between the ratio of the glass surface area to the volume of the
leachant (S/V) and the leachate pH is discussed in terms of a simple model of the glass …
