Description

The time-dependent temperature of the glass is considered in assessing its dissolution rate and the heat generated by HLW is considered in terms of its wider effects on the engineered barrier system. In particular, heat output is considered in repository design in order to ensure that thermal criteria, especially for bentonite, are met.
