Product consistency test of fully radioactive high-sodium content borosilicate glass K-26

摘要

Chemical durability of fully radioactive, high-sodium borosilicate glass K-26 was evaluated using the product consistency test PCT-A. Examination revealed normalised leaching rates as high as 5.93 ·10~(-2), 4.05 · 10~(-2) and 2.93 · 10~(-2) g/m~2 · day for sodium, boron and silicon respectively. Data on chemical durability of glass K-26 are consistent with similar composition glasses. These are of particular interest for performance assessment models.
